+
+```bash
+# Enable agent teams
+export CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
+
+# Scenario: Authentication feature (security-critical, coordination needed)
+# - 8 tasks (backend + frontend)
+# - Backend/frontend must align on API contracts
+# - Security review critical
+# - Emergent requirements likely
+
+# Result:
+# - 4 agents (lead + 2 impl + reviewer)
+# - 105 minutes (vs 180 with subagents)
+# - $180 cost (vs $70 with subagents)
+# - 8 security issues caught
+# - Verdict: Cost justified
+```
+
+### When to Use Subagents
+
+```bash
+# Scenario: CRUD endpoints (independent, clear patterns)
+# - 5 endpoints (each standalone)
+# - No coordination needed
+# - Sequential acceptable
+
+# Result:
+# - Subagent per task
+# - Standard review process
+# - $40 cost
+# - Verdict: Teams would be overkill
+```
+
+## Testing Strategy
+
+### What Was Tested
+
+- ✅ Documentation completeness
+- ✅ Code review (no issues found)

+# Agent Teams Support Analysis
+
+## Executive Summary
+
+This document analyzes the work needed to add native Claude Agent Teams support to Superpowers alongside the current subagents approach. Agent Teams is a new experimental feature in Claude Code (Opus 4.6+) that enables direct inter-agent communication and collaborative AI workflows.
+
+## Current State: Subagent Architecture
+
+### How Subagents Work in Superpowers
+
+The current `subagent-driven-development` skill uses a **hub-and-spoke model**:
+
+1. **Lead agent (controller)** orchestrates everything
+2. **Fresh subagent per task** - no context pollution
+3. **Two-stage review process**:
+   - Spec compliance reviewer (did they build what was requested?)
+   - Code quality reviewer (is it well-built?)
+4. **All communication through lead** - subagents report back, lead dispatches next
+
+**Key characteristics:**
+- Sequential task execution (one after another)
+- Subagents are isolated - no awareness of each other
+- Controller provides full context to each subagent
+- Review cycles ensure quality before moving forward
+- Cost-effective for independent sequential tasks
+
+### Existing Parallel Approach
+
+The `dispatching-parallel-agents` skill enables **concurrent subagent execution**:
+
+- Multiple subagents work simultaneously on independent problems
+- Each has focused scope (e.g., different test files, subsystems)
+- Still report only to lead agent
+- Used for independent debugging or parallel fixes
+
+**Limitations:**
+- No inter-agent collaboration or discussion
+- Can't share findings or coordinate dependencies
+- Can't challenge each other's approaches
+- No shared task state or self-organization
+
+## New Capability: Agent Teams
+
+### What Agent Teams Add
+
+Agent Teams (introduced in Opus 4.6) provide:
+
+1. **Independent context windows** - Each teammate is a full session
+2. **Direct inter-agent communication** - Agents message each other, not just lead
+3. **Shared task list** - Agents claim/assign/complete tasks collaboratively
+4. **Self-coordination** - Agents can negotiate, delegate, resolve dependencies
+5. **Peer review** - Agents can challenge findings and collaborate on solutions
+
+### Technical Architecture
+
+**Communication primitives:**
+```
+- send_message: Agent-to-agent messaging
+- read_inbox: Check for new messages
+- poll_inbox: Wait for messages asynchronously
+```
+
+**Team structure:**
+```
+~/.claude/teams/<team-name>/
+  ├── tasks.json          # Shared task list
+  └── inboxes/
+      ├── lead.json       # Lead agent's inbox
+      ├── agent-1.json    # Teammate 1's inbox
+      └── agent-2.json    # Teammate 2's inbox
+```
+
+**Enable with:**
+```bash
+export CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
+```
+
+### When Agent Teams Excel
+
+**Best for:**
+- Complex multi-module refactoring requiring coordination
+- Adversarial development (one agent writes, another tries to break)
+- Research requiring multiple perspectives and discussion
+- Cross-layer features needing negotiation between frontend/backend
+- Tasks with uncertain dependencies that emerge during work
+
+**Not optimal for:**
+- Simple sequential task lists
+- Cost-sensitive projects (each agent = full Claude instance)
+- Tasks with clear sequential dependencies
+- When final result is all that matters (no collaboration benefit)
+
+## Gap Analysis: What's Missing
+
+### 1. Team Orchestration Skill
+
+**Need:** New skill `team-driven-development` parallel to `subagent-driven-development`
+
+**Would include:**
+- When to use teams vs subagents (decision flowchart)
+- How to initialize a team (team name, roles, task list)
+- Team lead responsibilities (orchestration, conflict resolution)
+- Teammate responsibilities (claim tasks, communicate, coordinate)
+- How to handle inter-agent disagreements
+- When to escalate to human
+
+### 2. Team Member Prompts
+
+**Need:** Prompt templates for team roles (not just isolated subagents)
+
+**Required prompts:**
+- `team-lead-prompt.md` - Orchestrator and facilitator
+- `teammate-implementer-prompt.md` - Team-aware implementer
+- `teammate-reviewer-prompt.md` - Collaborative reviewer
+- `teammate-researcher-prompt.md` - Exploration and options
+
+**Key differences from current prompts:**
+- Include team context and member roster
+- Encourage inter-agent communication
+- Define when to message vs execute
+- Handle concurrent work conflicts
+
+### 3. Communication Patterns
+
+**Need:** Structured patterns for agent interactions
+
+**Examples needed:**
+- Request review from peer agent
+- Negotiate dependency resolution
+- Share findings and get feedback
+- Escalate blocking issue to lead
+- Coordinate on shared resources
+- Challenge implementation approach
+
+### 4. Team Configuration
+
+**Need:** Team setup and initialization utilities
+
+**Would include:**
+- Team composition guidance (how many agents? what roles?)
+- Task distribution strategies
+- Conflict resolution protocols
+- Progress monitoring for teams
+- Cost estimation for team vs subagent approach
+
+### 5. Integration with Existing Skills
+
+**Skills that would need team-aware versions:**
+
+1. **writing-plans** - Generate team-compatible task lists
+   - Mark tasks as parallel-safe or requiring coordination
+   - Identify dependency groups
+   - Suggest team composition
+
+2. **requesting-code-review** - Support peer review between agents
+   - Enable reviewer-implementer dialogue
+   - Allow multiple reviewers to discuss findings
+
+3. **systematic-debugging** - Parallel investigation by team
+   - Agents explore different hypotheses simultaneously
+   - Share findings and discuss root cause
+
+4. **finishing-a-development-branch** - Team completion
+   - Ensure all agents have finished
+   - Consolidated review of team output
+   - Handle conflicts in changes
+
+### 6. Documentation and Guidance
+
+**Need:** Clear when-to-use guidance and examples
+
+**Documents needed:**
+- Comparison matrix (teams vs subagents vs manual)
+- Cost analysis and budgeting guide
+- Real-world case studies
+- Troubleshooting team coordination issues
+- Best practices for team composition
+
+## Proposed Architecture
+
+### Coexistence Strategy
+
+Both approaches should be available with clear guidance on when to use each:
+
+```
+Have implementation plan?
+  ├─ Tasks highly independent? → subagent-driven-development
+  ├─ Tasks require coordination? → team-driven-development  
+  └─ Tasks tightly coupled? → Manual or executing-plans
+```
+
+### Skill Hierarchy
+
+```
+Collaboration Skills:
+  ├─ subagent-driven-development (existing)
+  │   ├─ Sequential execution
+  │   ├─ Hub-and-spoke model
+  │   └─ Cost-effective
+  │
+  ├─ team-driven-development (new)
+  │   ├─ Collaborative execution
+  │   ├─ Peer-to-peer communication
+  │   └─ Resource-intensive
+  │
+  └─ dispatching-parallel-agents (existing)
+      ├─ Concurrent execution
+      ├─ Independent scopes
+      └─ No coordination needed
+```
+
+### Minimal Implementation Approach
+
+**Phase 1: Core Team Skill**
+1. Create `team-driven-development/SKILL.md`
+2. Define team initialization process
+3. Create basic team member prompts
+4. Document message passing patterns
+5. Add when-to-use decision tree
+
+**Phase 2: Integration**
+1. Update `writing-plans` with team-compatibility markers
+2. Add team-aware version notes to related skills
+3. Create comparison documentation
+
+**Phase 3: Examples and Testing**
+1. Create example team scenarios
+2. Test with real development tasks
+3. Document cost comparisons
+4. Refine based on learnings
+
+## Key Design Decisions
+
+### 1. Coexistence vs Replacement
+
+**Decision:** Coexistence - both approaches remain available
+
+**Rationale:**
+- Subagents are simpler and more cost-effective for many tasks
+- Agent teams are overkill for sequential independent tasks
+- Users should choose based on task requirements
+- Existing workflows shouldn't be disrupted
+
+### 2. Opt-in vs Automatic
+
+**Decision:** Explicit opt-in to agent teams
+
+**Rationale:**
+- Experimental feature requiring configuration
+- Significantly higher token costs
+- Users should consciously choose team approach
+- Avoid unexpected behavior changes
+
+### 3. Skill Structure
+
+**Decision:** New parallel skill, not modification of existing
+
+**Rationale:**
+- Clear separation of concerns
+- Different mental models (sequential vs collaborative)
+- Easier to document and understand
+- Lower risk of breaking existing workflows
+
+### 4. Integration Depth
+
+**Decision:** Light integration initially, deeper over time
+
+**Rationale:**
+- Start with standalone team skill
+- Let patterns emerge from usage
+- Avoid over-engineering before validation
+- Iteratively improve based on real experience
+
+## Implementation Roadmap
+
+### Milestone 1: Research & Analysis (Current)
+- ✅ Research agent teams feature
+- ✅ Analyze current architecture
+- ✅ Identify gaps and requirements
+- ✅ Create implementation plan
+
+### Milestone 2: Core Team Skill (Next)
+- Create `skills/team-driven-development/SKILL.md`
+- Write team member prompt templates
+- Document message passing patterns
+- Add team initialization guide
+- Test with sample scenario
+
+### Milestone 3: Documentation
+- Create comparison guide (teams vs subagents)
+- Document team composition best practices
+- Add configuration instructions
+- Create cost analysis guide
+- Write troubleshooting guide
+
+### Milestone 4: Integration (Future)
+- Update `writing-plans` for team tasks
+- Add team hints to related skills
+- Create team-aware debugging patterns
+- Build team coordination utilities
+
+### Milestone 5: Validation (Future)
+- Real-world testing with teams
+- Cost-benefit analysis
+- Performance benchmarking
+- User feedback integration
+- Pattern refinement
+
+## Cost Considerations
+
+### Token Usage Comparison
+
+**Subagent-driven-development:**
+- 1 implementer + 2 reviewers per task = 3 subagent calls
+- Controller does prep work (extracts context)
+- Review loops add iterations
+- Typical: 3-5 subagent invocations per task
+
+**Team-driven-development:**
+- 1 lead + N teammates (full sessions each)
+- Each agent maintains full context
+- Inter-agent messages add overhead
+- Typical: N * (full session cost) + message overhead
+
+**Estimation:**
+- Teams are 2-4x more expensive in tokens
+- BUT can be faster wall-clock time for collaborative tasks
+- Trade-off: Cost vs speed vs collaboration quality
+
+### When Cost is Justified
+
+Agent teams worth the cost when:
+- Task complexity benefits from multiple perspectives
+- Coordination overhead would be high manually
+- Adversarial validation adds significant value
+- Time-to-completion is critical
+- Research/exploration phase needs breadth
+
+Not justified when:
+- Tasks are clearly independent
+- Sequential execution is fine
+- Budget is constrained
+- Simple review suffices
+- Pattern is well-established
+
+## Risks and Mitigations
+
+### Risk 1: Over-complexity
+**Mitigation:** Start simple, add complexity only as needed
+
+### Risk 2: High costs surprise users
+**Mitigation:** Clear cost warnings in documentation and prompts
+
+### Risk 3: Coordination overhead wastes time
+**Mitigation:** Provide clear patterns for when agents should communicate
+
+### Risk 4: Feature remains experimental
+**Mitigation:** Document fallback to subagents if teams unavailable
+
+### Risk 5: Conflicts in concurrent work
+**Mitigation:** Task planning emphasizes conflict-free work distribution
+
+## Success Metrics
+
+### Adoption Metrics
+- Number of users enabling agent teams
+- Frequency of team-driven-development usage
+- Team size distribution (how many agents typically?)
+
+### Quality Metrics
+- Defect rate: teams vs subagents vs manual
+- Review cycle count before approval
+- Implementation accuracy (spec compliance)
+
+### Efficiency Metrics
+- Wall-clock time: teams vs subagents
+- Token usage per completed task
+- Tasks completed before human intervention needed
+
+### User Experience
+- User satisfaction ratings
+- When-to-use guidance clarity
+- Documentation effectiveness
+- Support ticket frequency
+
+## Conclusion
+
+Adding native agent teams support to Superpowers is feasible and valuable, but should be implemented as a complementary approach rather than a replacement for the existing subagent model. The key is providing clear guidance on when each approach is appropriate and ensuring both can coexist harmoniously.
+
+**Recommended approach:**
+1. Start with a standalone `team-driven-development` skill
+2. Create comprehensive documentation on when to use teams
+3. Test with real scenarios to validate patterns
+4. Gradually integrate with existing skills as patterns stabilize
+5. Monitor costs and effectiveness to refine guidance
+
+The experimental nature of the feature and its higher cost profile mean it should be opt-in and clearly documented, allowing users to make informed choices about when collaborative agent teams provide sufficient value to justify the additional expense.

+# Agent Teams vs Subagents: Comparison Guide
+
+This guide helps you choose between Claude's Agent Teams and the traditional Subagent approach for executing implementation plans.
+
+## Quick Decision Matrix
+
+| Your Situation | Recommended Approach |
+|----------------|---------------------|
+| Independent tasks, sequential execution OK | **subagent-driven-development** |
+| Tasks need coordination, agents must collaborate | **team-driven-development** |
+| Multiple independent bugs/problems | **dispatching-parallel-agents** |
+| Budget constrained | **subagent-driven-development** |
+| Speed critical, cost secondary | **team-driven-development** |
+| Unclear dependencies, need flexibility | **team-driven-development** |
+| Clear specs, well-defined tasks | **subagent-driven-development** |
+| Adversarial review beneficial | **team-driven-development** |
+
+## Detailed Comparison
+
+### Architecture
+
+**Subagent-Driven Development:**
+```
+        Lead Agent
+         /  |  \
+        /   |   \
+       /    |    \
+   Sub1  Sub2  Sub3
+   (task 1→2→3, sequential)
+   
+- Fresh subagent per task
+- All communication through lead
+- No agent-to-agent communication
+- Sequential task execution
+```
+
+**Team-Driven Development:**
+```
+         Lead Agent
+         /    |    \
+        /     |     \
+       /      |      \
+   Agent1 ←→ Agent2 ←→ Agent3
+   (parallel + coordination)
+   
+- Persistent teammate sessions  
+- Direct peer-to-peer messaging
+- Shared task list
+- Parallel task execution
+```
+
+### Team Composition Flexibility
+
+**Subagents (rigid structure):**
+- Fixed 3-role pattern per task: Implementer → Spec Reviewer → Code Quality Reviewer
+- Same structure every time, no customization
+- Roles are predetermined by the skill
+
+**Agent Teams (flexible composition):**
+- **Customizable roles** based on project needs
+- Examples: Frontend/Backend specialists, Security expert, Performance analyst, Documentation writer
+- Team size adaptable (3-6 agents)
+- Roles can be specialized (e.g., "React specialist") or generalized (e.g., "Full-stack developer")
+- Mix and match based on task complexity
+
+**Key insight:** Subagents are a fixed workflow; agent teams are a collaboration framework you adapt to your needs.
+
+### Communication Model
+
+**Subagents:**
+- Hub-and-spoke topology
+- Subagent reports to lead
+- Lead dispatches next subagent
+- No context shared between subagents
+- Communication overhead: O(n) where n = tasks
+
+**Agent Teams:**
+- Mesh topology (agents can message each other)
+- Agents coordinate directly
+- Shared task state
+- Context builds up within each agent
+- Communication overhead: O(n*m) where n = agents, m = coordination points
+
+### Cost Structure
+
+**Subagent Approach:**
+```
+Per task:
+- 1 implementer subagent call
+- 1 spec reviewer subagent call  
+- 1 code quality reviewer subagent call
+- Controller prep/orchestration overhead
+
+Total: ~3-5 subagent invocations per task
+Example: 10 tasks × 4 calls × $2 = $80
+```
+
+**Agent Team Approach:**
+```
+Per team session:
+- N full agent sessions (lead + teammates)
+- Message passing overhead
+- Shared context maintenance
+
+Total: ~N × $40-50 per agent + overhead
+Example: 4 agents × $45 = $180
+
+Typical multiplier: 2-4x cost of subagent approach
+```
+
+### When Each Excels
+
+**Use Subagents When:**
+- ✅ Tasks are clearly independent
+- ✅ Sequential execution is acceptable  
+- ✅ Budget is constrained
+- ✅ Well-established patterns
+- ✅ Simple review suffices
+- ✅ No emergent dependencies expected
+
+**Use Agent Teams When:**
+- ✅ Tasks have interdependencies
+- ✅ Coordination needed between parallel work
+- ✅ Multiple perspectives add value
+- ✅ Adversarial review beneficial
+- ✅ Speed more important than cost
+- ✅ Architectural decisions needed during work
+- ✅ Research/exploration phase
+
+### Real-World Scenarios
+
+#### Scenario 1: CRUD API Endpoints (5 endpoints)
+
+**Analysis:**
+- Tasks are independent (each endpoint standalone)
+- Clear patterns (REST conventions)
+- No coordination needed
+- Sequential is fine
+
+**Recommendation:** Subagent-driven-development
+
+**Why:** Each endpoint can be built, reviewed, and completed independently. No collaboration benefit. Subagents are more cost-effective.
+
+**Estimated cost:** 5 tasks × 4 subagents × $2 = $40
+
+---
+
+#### Scenario 2: Authentication System (8 tasks)
+
+**Analysis:**
+- Backend and frontend must coordinate
+- Security reviewer needs to challenge implementation
+- Dependencies emerge during work (token format, error handling)
+- Multiple layers need alignment
+
+**Recommendation:** Team-driven-development
+
+**Why:** Backend implementer and frontend implementer need to align on contracts. Security reviewer provides adversarial validation. Coordination overhead justifies team approach.
+
+**Estimated cost:** 4 agents (lead + 2 impl + reviewer) × $45 = $180
+
+---
+
+#### Scenario 3: Bug Fixes (6 unrelated bugs)
+
+**Analysis:**
+- Independent failures
+- Different subsystems
+- No shared state
+- Can work in parallel
+
+**Recommendation:** dispatching-parallel-agents
+
+**Why:** Pure parallel execution with no coordination. Even simpler than teams - just dispatch concurrent subagents with focused scopes.
+
+**Estimated cost:** 6 subagents × $3 = $18
+
+---
+
+#### Scenario 4: Database Migration (12 tasks)
+
+**Analysis:**
+- Schema changes affect multiple services
+- Migration scripts must coordinate
+- Rollback strategy needs discussion
+- Data integrity critical
+
+**Recommendation:** Team-driven-development
+
+**Why:** High coordination needs. Multiple agents can explore impact, challenge approaches, and ensure consistency. Worth the cost for mission-critical work.
+
+**Estimated cost:** 5 agents × $50 = $250
+
+---
+
+#### Scenario 5: Refactoring (10 files)
+
+**Analysis:**
+- Each file can be refactored independently
+- Tests verify correctness
+- Pattern is clear (existing code shows the way)
+- No coordination needed
+
+**Recommendation:** Subagent-driven-development
+
+**Why:** Classic independent task pattern. Each file is a task. No collaboration benefit. Subagents are sufficient.
+
+**Estimated cost:** 10 tasks × 4 subagents × $2 = $80

+
+## Migration Path
+
+### Starting with Subagents
+
+Begin with subagent-driven-development for most projects:
+- Lower cost
+- Simpler orchestration
+- Proven workflow
+- Predictable results
+
+### When to Consider Teams
+
+Switch to agent teams when you hit:
+- Coordination bottlenecks (too much lead agent back-and-forth)
+- Emergent dependencies (tasks aren't as independent as thought)
+- Quality issues from lack of discussion (agents should challenge each other)
+- Time pressure (parallelization worth the cost)
+
+### Hybrid Approach
+
+You can mix approaches in the same project:
+1. Use teams for complex coordinated phases (architecture, integration)
+2. Switch to subagents for independent implementation phases
+3. Use teams again for final integration and testing
+
+**Example:**
+```
+Phase 1: Planning (manual)
+Phase 2: Core architecture (agent team - coordination critical)
+Phase 3: Independent features (subagents - clear tasks)
+Phase 4: Integration (agent team - coordination critical)
+Phase 5: Bug fixes (dispatching-parallel-agents)
+```
+
+## Cost-Benefit Analysis Framework
+
+### Calculate Break-Even Point
+
+Agent teams worth it if:
+```
+(Team Cost - Subagent Cost) < (Human Time Saved × Hourly Rate)
+
+Example:
+Teams: $180
+Subagents: $60
+Difference: $120
+
+If teams save 2+ hours at $60/hr: Worth it
+If teams save 1 hour at $60/hr: Not worth it
+```
+
+### Factor in Quality
+
+Also consider:
+- Cost of bugs that reach production
+- Value of adversarial review catching issues early
+- Speed-to-market for time-sensitive features
+
+High-stakes work (security, payments, data integrity): Quality premium justifies team approach
+
+### Monitor Real Costs
+
+Track actual costs:
+```
+Project: Authentication Feature
+Approach: Agent Team
+Agents: 4 (lead + 2 impl + reviewer)
+Actual cost: $195
+Time to complete: 3 hours
+Issues found: 3 security flaws (caught in peer review)
+
+Estimated subagent cost: $70
+Estimated time: 8 hours
+Issues caught: Unknown (sequential review might miss)
+
+Verdict: Team justified - security findings and 5hr time savings
+```
+
+## Common Pitfalls
+
+### Using Teams When Subagents Sufficient
+
+**Symptom:** Agents aren't messaging each other, just implementing independently
+
+**Fix:** Tasks are too independent. Use subagents instead.
+
+### Using Subagents When Teams Needed
+
+**Symptom:** Lead agent doing excessive back-and-forth, reimplementing context for each subagent
+
+**Fix:** Too much coordination overhead. Use teams instead.
+
+### Wrong Team Size
+
+**Symptom:** Costs exploding with 8+ agents, most sitting idle
+
+**Fix:** Team too large. Reduce to 3-6 agents max.
+
+### Over-Communication
+
+**Symptom:** More messages than implementations, no forward progress
+
+**Fix:** Tasks too tightly coupled. Either break dependencies or do sequentially.
+
+### Under-Communication
+
+**Symptom:** Team members building incompatible implementations
+
+**Fix:** More coordination needed. Lead should actively facilitate discussions.
+
+## Summary
+
+**Default choice:** Subagent-driven-development
+- Cost-effective
+- Simple orchestration
+- Works for most projects
+
+**Upgrade to teams when:**
+- Coordination overhead high
+- Multiple perspectives add significant value
+- Speed critical
+- Budget allows 2-4x cost multiplier
+
+**Key insight:** Agent teams are a premium feature for complex collaborative work. Use them strategically where coordination and discussion provide clear value, not as a default replacement for subagents.

+## Multi-Feature Detection
+
+After clarifying questions, assess whether the request contains multiple distinct features. A "distinct feature" is functionality that could ship independently — it has its own user-facing behavior, its own tests, and its own reason to exist.
+
+**Signals of multi-feature scope:**
+- User describes unrelated behaviors in a single request ("add auth AND a reporting dashboard")
+- Different subsystems or layers affected with no shared purpose
+- Request would naturally map to multiple PRs in a code review
+
+**If multiple features detected, present the scope check:**
+
+```
+I've identified N distinct features in this request:
+
+1. **Feature A** — [one-line description]
+2. **Feature B** — [one-line description]
+3. **Shared dependency** — [if any: e.g., "both need a new user model"]
+
+Options:
+1. Focus on one feature (recommended — lower risk, cleaner PRs)
+2. Proceed with all features (higher risk — requires multi-feature orchestration)
+
+Which would you prefer? If focusing, which feature first?
+```
+
+**If user picks one feature:** Continue the normal single-feature path. Note the other features for future sessions.
+
+**If user picks all features (multi-feature mode):**
+1. Run the multi-worktree readiness audit (see superpowers:using-git-worktrees) — identify port conflicts, environment gaps, platform-specific needs (scratch orgs, venvs, etc.) that could block parallel development. Remediation tasks become part of the shared dependency plan or a setup phase in the coordination manifest.
+2. Identify shared dependencies between features — code that multiple features need but that doesn't exist yet
+3. Design each feature independently but note integration points
+4. Present designs per-feature (each gets its own approval)
+5. Write one design doc per feature, plus one for each shared dependency
+6. At transition, invoke writing-plans with multi-feature context so it creates a coordination manifest
+
+**Key constraint:** Each agent works on one feature or one shared dependency. Never assign an agent work that spans features. This preserves agent context and prevents cross-feature interference.

+## Multi-Feature Context
+
+When executing a plan that is part of a multi-feature coordination manifest, you are one agent in one worktree working on one plan. The orchestrator manages the bigger picture.
+
+**What changes:**
+- Your plan file is one of several referenced by a coordination manifest
+- You work only in your assigned worktree — never modify files outside it
+- Shared dependencies may have been merged into your worktree before you started — treat them as existing code, not something you build
+- When you finish, report completion to the orchestrator. Do NOT start work on another feature's plan

+- Load and review your plan exactly as in single-feature mode
+- Execute in batches with checkpoints
+- Follow all the same quality gates

+## Multi-Feature Completion
+
+When this skill is called as part of a multi-feature coordination manifest, there are two levels of completion:
+
+### Per-Worktree Completion (called by each agent)
+
+Each agent finishing its feature/dependency worktree follows the normal process above (verify tests → present options → execute). Typically the agent chooses **Option 3 (Keep as-is)** because integration is handled by the orchestrator.
+
+### Orchestrator Integration (after all worktrees complete)
+
+The orchestrator merges completed branches into the base branch in the order defined by the coordination manifest:
+
+```bash
+# 1. Merge shared dependencies first
+git checkout <base-branch>
+git merge feature/shared-dep-1 --no-edit
+<test command>  # Must pass before continuing
+
+# 2. Merge features in manifest order
+git merge feature/feature-1 --no-edit
+<test command>  # Must pass before continuing
+
+git merge feature/feature-2 --no-edit
+<test command>  # Must pass — full integration verified
+```
+
+**If merge conflicts occur:** Resolve in context of the base branch. The conflict likely means two features touched the same code — this is the integration risk the user accepted in multi-feature mode.
+
+**If tests fail after a feature merge:** The feature may have an incompatibility with previously merged work. Fix before merging the next feature.
+
+**After all merges:**
+- Clean up all worktrees: `git worktree remove <path>` for each
+- Clean up feature branches: `git branch -d <branch>` for each
+- Report final integration status

+## Multi-Feature Context
+
+When dispatched by an orchestrator as part of a multi-feature coordination manifest, this skill executes one plan in one worktree. The same single-feature process applies with these additions:
+
+- **Scope is your plan only.** The orchestrator assigned you a specific plan file — execute only that plan's tasks.
+- **Shared dependencies are pre-merged.** The orchestrator distributed completed dependency branches into your worktree before starting you. Treat that code as existing baseline.
+- **Report completion to orchestrator.** After all tasks pass review and finishing-a-development-branch runs, the orchestrator handles integration with other feature branches.
+- **Never cross worktree boundaries.** If you discover your feature needs code from another feature's domain, flag it to the orchestrator — don't implement it yourself.

+
+# Team-Driven Development
+
+Execute implementation plans using collaborative agent teams with direct inter-agent communication, shared task lists, and self-coordination.
+
+**Core principle:** Multiple agents with independent contexts + direct communication + shared task state = collaborative problem-solving for complex coordinated work
+
+**⚠️ EXPERIMENTAL:** Requires Claude Code with Opus 4.6+ and `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`
+
+## When to Use
+
+```dot
+digraph when_to_use {
+    "Have implementation plan?" [shape=diamond];
+    "Tasks need coordination?" [shape=diamond];
+    "Budget allows teams?" [shape=diamond];
+    "team-driven-development" [shape=box style=filled fillcolor=lightblue];
+    "subagent-driven-development" [shape=box];
+    "Manual or brainstorm first" [shape=box];
+
+    "Have implementation plan?" -> "Tasks need coordination?" [label="yes"];
+    "Have implementation plan?" -> "Manual or brainstorm first" [label="no"];
+    "Tasks need coordination?" -> "Budget allows teams?" [label="yes - agents must collaborate"];
+    "Tasks need coordination?" -> "subagent-driven-development" [label="no - independent tasks"];
+    "Budget allows teams?" -> "team-driven-development" [label="yes - 2-4x cost OK"];
+    "Budget allows teams?" -> "subagent-driven-development" [label="no - use sequential"];
+}
+```
+
+**Use agent teams when:**
+- Tasks have emergent dependencies that need negotiation
+- Multiple perspectives improve quality (adversarial review)
+- Agents benefit from discussing approaches
+- Coordination overhead would be high through lead agent only
+- Real-time collaboration adds value
+- Wall-clock time is more important than token cost
+
+**Use subagents instead when:**
+- Tasks are clearly independent (no coordination needed)
+- Sequential execution is acceptable
+- Budget is constrained (teams cost 2-4x more)
+- Simple hub-and-spoke review suffices
+- Well-established patterns with clear specs
+
+**Cost reality:**
+- Each teammate is a **full Claude instance** (separate session)
+- 3-agent team = 3x base cost + message overhead
+- Teams trade tokens for speed and collaboration quality
+- Budget $50-200+ per team session depending on complexity
+
+## Agent Teams vs Subagents
+
+| Aspect | Subagents | Agent Teams |
+|--------|-----------|-------------|
+| **Communication** | Hub-and-spoke (only through lead) | Peer-to-peer (direct messages) |
+| **Context** | Fresh per task | Persistent per agent |
+| **Coordination** | Lead orchestrates everything | Self-organize with shared task list |
+| **Execution** | Sequential (one task at a time) | Parallel (multiple concurrent tasks) |
+| **Cost** | 3-5 subagent calls per task | N full sessions + overhead |
+| **Best for** | Independent sequential tasks | Coordinated collaborative work |
+| **Review model** | Two-stage (spec, then quality) | Peer review with discussion |
+
+## Prerequisites
+
+### 1. Environment Setup
+
+Enable agent teams in Claude Code:
+
+```bash
+# Option 1: Environment variable
+export CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
+
+# Option 2: Claude Code settings (~/.claude/settings.json)
+{
+  "env": {
+    "CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS": "1"
+  }
+}
+```
+
+Verify enabled:
+```bash
+claude --version  # Should show Opus 4.6+
+echo $CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS  # Should show: 1
+```
+
+### 2. Plan Preparation
+
+Your implementation plan should identify:
+- Which tasks can run in parallel vs need sequencing
+- Which tasks have dependencies on each other
+- Where coordination between agents is beneficial
+- Suggested team composition (roles needed)
+
+## Team Composition
+
+**⚡ Flexible by Design:** Unlike the fixed subagent structure (always 1 implementer + 2 reviewers), agent teams support **any role composition** based on your project needs. The roles below are recommendations, not requirements.
+
+### Common Role Patterns
+
+**Team Lead (required):**
+- Orchestrates team and manages shared task list
+- Resolves conflicts and escalates to human when needed
+- Monitors progress and ensures completion
+- Does NOT implement - delegates to teammates
+
+**Implementer(s) (1-3):**
+- Claim and implement tasks from shared list
+- Communicate dependencies and blockers
+- Request reviews from reviewer teammates
+- Follow TDD and existing patterns
+
+**Reviewer(s) (1-2):**
+- Review completed implementations
+- Provide feedback via direct messages
+- Collaborate with implementers on fixes
+- Ensure quality before marking tasks complete
+
+**Researcher (optional):**
+- Explores uncertain areas
+- Evaluates multiple approaches
+- Shares findings with team
+- Helps make architectural decisions
+
+### Customization Examples
+
+Adapt roles to your project:
+- **Full-stack feature:** Frontend specialist + Backend specialist + Integration tester
+- **Security-critical:** Implementer + Security reviewer + Penetration tester
+- **Documentation-heavy:** Developer + Technical writer + Examples creator
+- **Performance work:** Implementer + Performance analyst + Optimization specialist
+- **Legacy migration:** Code migrator + Test writer + Compatibility verifier
+
+### Team Size Guidelines
+
+- **Small tasks (2-5 tasks):** 1 lead + 1 implementer + 1 reviewer = 3 agents
+- **Medium projects (6-15 tasks):** 1 lead + 2 implementers + 1 reviewer = 4 agents
+- **Large projects (15+ tasks):** 1 lead + 2-3 implementers + 2 reviewers = 5-6 agents
+
+**Never exceed 6 agents** - coordination overhead dominates beyond this

+
+### 3. Spawn Team Members
+
+Use prompt templates from `./team-*-prompt.md` files:
+
+```
+# Lead agent (you) - Already active
+
+# Spawn implementer-1
+Task tool (general-purpose):
+  description: "Backend implementer for auth feature"
+  prompt: [Use ./team-implementer-prompt.md with team context]
+
+# Spawn implementer-2  
+Task tool (general-purpose):
+  description: "Frontend implementer for auth feature"
+  prompt: [Use ./team-implementer-prompt.md with team context]
+
+# Spawn reviewer-1
+Task tool (general-purpose):
+  description: "Security reviewer for auth feature"
+  prompt: [Use ./team-reviewer-prompt.md with team context]
+```
+
+### 4. Team Coordination
+
+**Lead responsibilities:**
+- Monitor shared task list for claimed/completed tasks
+- Read incoming messages from teammates
+- Resolve conflicts when multiple agents claim same task
+- Answer questions and provide clarifications
+- Escalate to human when blocked
+
+**Teammate workflow:**
+1. Read shared task list
+2. Claim available task (or wait if dependencies not met)
+3. Implement task following TDD
+4. Communicate blockers or questions to relevant teammate
+5. Request review when complete
+6. Address review feedback
+7. Mark task complete in shared list
+
+### 5. Message Passing Patterns
+
+**Request dependency info:**
+```
+From: implementer-2 (frontend)
+To: implementer-1 (backend)
+Subject: Login API response format
+
+I'm implementing the login UI (task-3) and need to know the exact 
+response format from POST /api/auth/login. Can you share the schema?
+```
+
+**Report blocker:**
+```
+From: implementer-1 (backend)
+To: lead
+Subject: Blocked on JWT library choice
+
+Task-1 (JWT generation) is blocked. Need decision on library:
+- Option A: jsonwebtoken (mature, widely used)
+- Option B: jose (modern, better types)
+
+Which should we use? This affects task-2 as well.
+```
+
+**Request review:**
+```
+From: implementer-1 (backend)
+To: reviewer-1 (security)
+Subject: Review needed: JWT implementation
+
+Completed task-1 (JWT token generation). Please review:
+- Files: src/auth/jwt.ts, tests/auth/jwt.test.ts
+- Commits: abc123..def456
+- Focus areas: Token expiry, refresh token rotation, signing key management
+
+Let me know if you find any security issues.
+```
+
+**Provide review feedback:**
+```
+From: reviewer-1 (security)
+To: implementer-1 (backend)
+Subject: Re: JWT implementation - Issues found
+
+Security concerns in task-1:
+
+CRITICAL:
+- Signing key is hardcoded (jwt.ts:15) - Use environment variable
+- Token expiry too long (jwt.ts:23) - Reduce from 7d to 15m
+- No refresh token rotation (jwt.ts:45) - Implement rotation
+
+Please fix and request re-review.
+```
+
+### 6. Completion
+
+When all tasks marked complete:
+
+1. **Team review session** - Lead coordinates final review
+2. **Conflict resolution** - If multiple agents modified same files
+3. **Integration testing** - Run full test suite
+4. **Lead consolidates** - Creates summary of what was accomplished
+5. **Use finishing-a-development-branch** - Standard completion workflow
+
+## Multi-Feature Orchestration
+
+When a coordination manifest defines multiple features with shared dependencies, the team lead acts as **orchestrator** and sequences team deployments across worktrees.
+
+### Sequencing Team Deployments
+
+The orchestrator follows the manifest's execution order:
+
+```
+Phase 1: Deploy teams to shared dependency worktrees
+  → Wait for completion + review
+  → Distribute dependency branches to feature worktrees
+
+Phase 2: Deploy teams to feature worktrees (parallel)
+  → Each team operates independently in its own worktree
+  → Teams never reach into another worktree
+
+Phase 3: Integration
+  → Merge features into base branch per manifest order
+```
+
+### One Team Per Worktree
+
+Each worktree gets its own team (or subagent, for simpler plans). Teams are scoped to a single feature or dependency:
+
+```
+Worktree: .worktrees/shared-user-model
+  Team: lead + implementer-1 + reviewer-1
+  Plan: docs/plans/2025-03-15-shared-user-model.md
+
+Worktree: .worktrees/auth-feature
+  Team: lead + implementer-2 + reviewer-2
+  Plan: docs/plans/2025-03-15-auth-feature.md
+
+Worktree: .worktrees/reporting-feature
+  Team: lead + implementer-3 + reviewer-3
+  Plan: docs/plans/2025-03-15-reporting-feature.md
+```
+
+An agent that needs information from another feature's domain asks the orchestrator, not the other team's agents directly. This prevents context bleed.
+
+### Dependency-Aware Scheduling
+
+The orchestrator must not start a feature team until all of that feature's shared dependencies are:
+1. Complete (all tasks done, tests passing)
+2. Reviewed (code quality approved)
+3. Distributed (merged into the feature's worktree, tests passing post-merge)
+
+If dependencies are independent of each other, their teams can run in parallel. If dependencies have their own ordering (dependency B depends on dependency A), they must be sequenced.
+
+### Cost Implications
+
+Multi-feature orchestration multiplies team cost:
+
+```
+Single feature team (4 agents):   ~$160-180
+3-feature orchestration:
+  1 shared dependency team (3):   ~$100
+  2 feature teams (4 each):       ~$320
+  Orchestrator overhead:           ~$50
+  Total:                           ~$470
+
+vs. sequential single-feature:     ~$480-540  (3 × $160-180)
+```
+
+Parallel execution saves wall-clock time without significant cost increase. The orchestrator overhead is offset by eliminating context-switching between features.
+
+## Communication Best Practices
+
+### When to Message vs Execute
+
+**Message another agent when:**
+- You need information they have (API schema, interface contract)
+- Blocked on their work (dependency not complete)
+- Found issue in their code (security flaw, bug)
+- Need architectural decision (affects multiple tasks)
+- Uncertain about approach (want second opinion)
+
+**Just execute when:**
+- Task is clearly specified and unblocked
+- No coordination needed with other agents
+- Following established patterns
+- Review can happen after completion
+
+### Message Structure
+
+Good messages are:
+- **Specific:** Reference exact files, lines, task IDs
+- **Actionable:** Clear what response is needed
+- **Concise:** Respect other agent's context limit
+- **Timestamped:** For async coordination
+
+### Escalation to Human
+
+Escalate to human when:
+- Agents disagree on architectural approach
+- Multiple approaches seem equally valid
+- Blocked on external decision (API design, library choice)
+- Cost is escalating beyond expected (need budget check)
+- Task taking much longer than estimated
+
+## Red Flags
+
+**Never:**
+- Start team without enabling `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS`
+- Exceed 6 agents (coordination overhead too high)
+- Let agents claim same task (race condition)
+- Skip the shared task list (how do agents coordinate?)
+- Ignore messages from teammates (breaks collaboration)
+- Mix team and subagent approaches in same workflow
+- Forget to budget for full sessions per agent
+
+**If agents conflict:**
+- Lead arbitrates based on plan requirements
+- Prefer simpler approach unless complex has clear benefit
+- Escalate to human if no clear winner
+
+**If coordination is failing:**
+- Too many messages = task too tightly coupled (should be sequential)
+- No messages = tasks too independent (use subagents instead)
+- Long message chains = architectural decision needed (escalate)
+
+## Integration
+
+**Required workflow skills:**
+- **superpowers:using-git-worktrees** - REQUIRED: Isolated workspace for team (one per feature/dependency in multi-feature mode)
+- **superpowers:writing-plans** - Creates plan and coordination manifest for multi-feature
+- **superpowers:test-driven-development** - Teammates follow TDD
+- **superpowers:finishing-a-development-branch** - Complete after team done (per worktree, then integration)
+
+**Alternative workflows:**
+- **superpowers:subagent-driven-development** - Use for independent tasks or simpler feature worktrees that don't need full teams
+- **superpowers:dispatching-parallel-agents** - Use for truly independent parallel work
+- **superpowers:executing-plans** - Use for sequential manual execution
+
+## Cost Management
+
+### Estimation
+
+**Before starting, estimate:**
+```
+Base cost per task: ~$1-3 (depends on complexity)
+Number of tasks: 10
+Team size: 4 agents (1 lead + 2 implementers + 1 reviewer)
+
+Subagent approach:
+  10 tasks × 3 subagents/task × $2 = ~$60
+
+Team approach:
+  4 agents × full sessions × ~$40/session = ~$160
+  Plus message overhead: ~$20
+  Total: ~$180
+
+Multiplier: 3x cost for team approach
+Justified if: Coordination saves >3 hours of human time
+             or quality improvement worth >$120
+```
+
+### Cost Control
+
+**Reduce costs by:**
+- Smaller team (minimum: lead + implementer + reviewer = 3)
+- Shorter session (clear task boundaries, exit when done)
+- Fewer messages (provide full context upfront)
+- Clear task specs (reduce back-and-forth)
+
+**When to abort:**
+- Costs exceeding 5x estimate (something wrong)
+- Agents looping on coordination (architectural issue)
+- More messages than implementations (too much overhead)
+
+## Real-World Example
+
+See `./example-auth-feature.md` for a complete walkthrough of using team-driven development for an authentication feature. This example shows:
+- 8 tasks executed by 4 agents (lead + 2 implementers + reviewer)
+- Inter-agent coordination for API contracts
+- Security review catching 8 issues through adversarial discussion
+- Parallel implementation reducing wall-clock time
+- Cost comparison: $180 (teams) vs $70 (subagents), justified by security value and 75min time savings
+
+## Troubleshooting
+
+**"Agent teams not available"**
+- Check Claude Code version: `claude --version` (need Opus 4.6+)
+- Verify environment: `echo $CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS`
+- Try explicit enable: `export CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`
+
+**"Agents claiming same task"**
+- Implement task locking in shared task list
+- Lead assigns tasks explicitly instead of let agents claim
+- Smaller team (less contention)
+
+**"Too many messages, no progress"**
+- Tasks too tightly coupled - break dependencies
+- Architectural decision needed - escalate to human
+- Consider sequential execution instead
+
+**"Costs exploding"**
+- Check message count (excessive coordination?)
+- Verify team size is reasonable (<= 6 agents)
+- Consider switching to subagent approach mid-flight
+
+## Success Metrics
+
+Track to evaluate if teams worth it:
+- **Cost efficiency:** Cost per task vs subagent baseline
+- **Quality:** Defect rate, review cycles
+- **Speed:** Wall-clock time vs sequential
+- **Collaboration value:** Issues found by peer review that would be missed
+
+Compare against subagent-driven-development to decide which approach works better for your task types.

+# Example: Authentication Feature with Agent Teams
+
+This is a complete walkthrough of using team-driven-development to implement an authentication feature with 8 tasks, 4 agents, and inter-agent coordination.
+
+## Project Context
+
+**Goal:** Add user authentication to an existing web application
+
+**Requirements:**
+- JWT-based token authentication
+- Login/logout endpoints
+- Token refresh mechanism
+- Login UI component
+- Secure password handling
+- Session management
+
+**Team Size:** 4 agents
+- 1 Lead (orchestrator)
+- 2 Implementers (backend + frontend)
+- 1 Reviewer (security focus)
+
+**Estimated Cost:** ~$180 (vs ~$70 for subagents)
+**Why Teams Justified:** Security critical, backend/frontend coordination needed, adversarial review valuable
+
+## Step 1: Prerequisites
+
+### Enable Agent Teams
+
+```bash
+export CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
+claude --version  # Verify Opus 4.6+
+```
+
+### Set Up Git Worktree
+
+```bash
+# Using superpowers:using-git-worktrees
+git worktree add ../auth-feature -b feature/authentication
+cd ../auth-feature
+```
+
+### Review Implementation Plan
+
+Plan already exists at `docs/plans/authentication-feature.md` with 8 tasks:
+1. Password hashing utilities
+2. JWT token generation
+3. Login API endpoint
+4. Logout API endpoint
+5. Token refresh endpoint
+6. Session middleware
+7. Login UI component
+8. Logout UI button
+
+## Step 2: Initialize Team
+
+### Create Team Directory Structure
+
+```bash
+mkdir -p ~/.claude/teams/auth-feature/inboxes
+```
+
+### Create Initial Task List
+
+File: `~/.claude/teams/auth-feature/tasks.json`

+```
+
+## Step 4: Team Execution (Simulated Timeline)
+
+### T+0min: Initial Task Claims
+
+**backend-impl claims task-1** (password hashing)
+
+Update `tasks.json`:
+```json
+{
+  "id": "task-1",
+  "status": "in-progress",
+  "assignee": "backend-impl",
+  "claimed_at": "2026-02-16T10:05:00Z"
+}
+```
+
+**backend-impl claims task-2** (JWT tokens)
+
+Update `tasks.json`:
+```json
+{
+  "id": "task-2",
+  "status": "in-progress",
+  "assignee": "backend-impl",
+  "claimed_at": "2026-02-16T10:06:00Z"
+}
+```
+
+> Note: backend-impl can work on both since they're independent
+
+**frontend-impl waits** (tasks 7-8 depend on backend completing tasks 3-4)
+
+### T+15min: Task 1 Complete, Review Requested

+Implementation:
+- Using bcrypt with 12 rounds
+- Proper salt generation per password
+- Timing-safe comparison for verification
+
+Focus areas:
+- Salt rounds sufficient?
+- Any timing attack vectors?

+**security-reviewer → backend-impl:**
+```
+Subject: Re: task-1 - Issues found
+
+Reviewed task-1. Issues:

+CRITICAL:
+- bcrypt rounds hardcoded (password.ts:8) - Should be configurable via env var
+  Fix: Add BCRYPT_ROUNDS env var with default 12
+
+IMPORTANT:
+- Error messages leak user existence (password.ts:45)
+  Current: "User not found" vs "Invalid password"
+  Fix: Use generic "Invalid credentials" for both cases
+
+Please fix and request re-review.
+```

+
+**security-reviewer → backend-impl:**
+```
+Subject: Re: task-2 - Issues found
+
+Reviewed task-2. Issues:
+
+CRITICAL:
+- No refresh token rotation (jwt.ts:78) - Reusing same refresh token
+  Fix: Generate new refresh token on each refresh, invalidate old one
+  
+- Token signing key fallback to default (jwt.ts:12)
+  Current: `const key = process.env.JWT_SECRET || 'default-secret'`
+  Fix: Throw error if JWT_SECRET not set (fail fast, don't use default)
+
+IMPORTANT:
+- No token revocation mechanism (jwt.ts overall)
+  Recommendation: Add token blacklist or versioning
+
+Please fix CRITICAL issues and request re-review.
+```
+
+### T+30min: Backend Fixes Issues
+
+**backend-impl fixes task-1:**
+- Made bcrypt rounds configurable
+- Unified error messages
+
+**backend-impl fixes task-2:**
+- Implemented refresh token rotation
+- Removed default secret fallback
+- Added token revocation via blacklist
+
+**backend-impl → security-reviewer:**
+```
+Subject: Re-review: tasks 1 & 2 (fixes applied)
+
+Fixed all CRITICAL issues:
+
+Task-1:
+- BCRYPT_ROUNDS env var added (defaults 12)
+- Error messages now generic "Invalid credentials"
+
+Task-2:
+- Refresh token rotation implemented
+- JWT_SECRET required (throws if missing)
+- Token blacklist added for revocation
+
+Please re-review both tasks.
+```
+
+### T+35min: Security Approval
+
+**security-reviewer → backend-impl:**
+```
+Subject: Tasks 1 & 2 - Approved ✅
+
+Both tasks approved after fixes:
+
+Task-1 (Password hashing):
+- Strengths: Proper bcrypt usage, good test coverage
+- All issues resolved
+
+Task-2 (JWT tokens):
+- Strengths: Solid token lifecycle, good security practices
+- All CRITICAL issues fixed
+- Token revocation is good addition
+
+You can mark both complete and proceed to task-3.

+
+POST /api/auth/login
+Request:
+{
+  "email": "user@example.com",
+  "password": "plaintextPassword"
+}
+
+Response (200):
+{
+  "user": {
+    "id": "uuid",
+    "email": "user@example.com",
+    "name": "User Name"
+  },
+  "accessToken": "jwt...",
+  "refreshToken": "jwt..."
+}
+
+Response (401):
+{
+  "error": "Invalid credentials"
+}
+
+Store tokens in httpOnly cookies for security.
+Let me know if you need changes.
+```
+
+**frontend-impl → backend-impl:**
+```
+Subject: Re: API contract
+
+Looks good! A few questions:
+
+1. Cookie names? (for reference in frontend)
+2. CSRF token handling? Should I include CSRF token in requests?
+3. CORS headers needed?
+
+Will start on task-7 once task-3 is complete and reviewed.
+```
+
+**backend-impl → frontend-impl:**
+```
+Subject: Re: API contract - Answers
+
+1. Cookie names: `accessToken`, `refreshToken`
+2. CSRF: Yes, include `X-CSRF-Token` header from cookie
+3. CORS: Already configured for localhost:3000 (dev) and our prod domain
+
+Proceeding with task-3 implementation now.
+```
+
+### T+50min: Task 3 Complete
+
+**backend-impl** completes task-3, requests review from security-reviewer
+
+**backend-impl** also claims and implements task-4 (logout) and task-5 (refresh) in parallel since dependencies met
+
+### T+60min: All Backend Tasks Complete & Reviewed
+
+After review cycles:
+- Tasks 3, 4, 5, 6 all implemented, reviewed, and approved
+- Total time for backend: ~60 minutes
+
+**backend-impl → frontend-impl:**
+```
+Subject: All backend tasks complete - You're unblocked
+
+All backend implementation done and reviewed:
+✅ Task-3: Login API (/api/auth/login)
+✅ Task-4: Logout API (/api/auth/logout)
+✅ Task-5: Refresh API (/api/auth/refresh)
+✅ Task-6: Session middleware
+
+You can proceed with tasks 7 & 8.
+
+API docs summary:
+[Provides complete API reference]
+
+Let me know if questions come up during implementation.
+```
+
+### T+65min: Frontend Implementation Begins
+
+**frontend-impl claims task-7** (Login UI)
+
+Implements React login form with:
+- Email/password inputs
+- Form validation
+- Error handling
+- Loading states
+- Calls POST /api/auth/login
+- Stores tokens (via cookies, backend handles)
+- Redirects on success
+
+### T+85min: Frontend Review - Issues Found
+
+**security-reviewer → frontend-impl:**
+```
+Subject: Re: task-7 - Issues found
+
+Reviewed task-7 (Login UI). Issues:
+
+CRITICAL:
+- Password visible in browser console (LoginForm.tsx:67)
+  Current: console.log('Submitting:', { email, password })
+  Fix: Remove console.log or exclude password
+
+IMPORTANT:
+- No XSS protection on error messages (LoginForm.tsx:45)
+  Current: {error} (renders raw HTML)
+  Fix: Use text content, not innerHTML
+
+- No rate limiting indication (LoginForm.tsx overall)
+  After 3 failed attempts, should show message about rate limiting
+  Coordinate with backend-impl on rate limit headers
+
+Please fix and request re-review.
+```
+
+**frontend-impl → backend-impl:**
+```
+Subject: Rate limit headers?
+
+Security-reviewer wants rate limit indication in UI.
+Does the backend send rate limit headers?
+If not, can you add them?
+```
+
+**backend-impl → frontend-impl:**
+```
+Subject: Re: Rate limit headers
+
+Good catch. I'll add rate limiting to task-3 implementation:
+- X-RateLimit-Remaining header
+- X-RateLimit-Reset header
+
+Give me 10 min to add and re-test.
+```
+
+**backend-impl** adds rate limiting, security-reviewer approves update
+
+**frontend-impl** fixes issues and adds rate limit UI
+
+### T+100min: All Tasks Complete
+
+**lead consolidates:**
+```
+Team Status: All Complete ✅
+
+Backend (6 tasks): ✅ Complete
+Frontend (2 tasks): ✅ Complete
+
+Total implementations: 8 tasks
+Review cycles: 12 reviews (some tasks reviewed multiple times)
+Issues found: 8 (all fixed)
+Time: ~100 minutes
+```
+
+### T+105min: Final Integration Test
+
+**lead runs full test suite:**
+```bash
+npm run test
+# All 47 tests pass ✅
+
+npm run test:integration
+# Integration tests pass ✅
+```
+
+**lead → human:**
+```
+Authentication feature implementation complete!
+
+Summary:
+- 8 tasks implemented and reviewed
+- Security-focused review caught 8 issues (all fixed)
+- Backend/frontend coordination smooth (5 coordination messages)
+- All tests passing
+
+Ready for superpowers:finishing-a-development-branch
+```
+
+## Step 5: Team Completion
+
+Use `finishing-a-development-branch` skill to:
+1. Review final state
+2. Create PR or merge
+3. Clean up worktree
+4. Document what was accomplished
+
+## Outcomes
+
+### What Agent Teams Enabled
+
+✅ **Real-time coordination:** Backend/frontend aligned on API contract before implementation
+
+✅ **Adversarial review:** Security reviewer challenged implementations, found 8 issues
+
+✅ **Parallel work:** Backend tasks 1-2 done simultaneously, frontend unblocked early
+
+✅ **Quick iteration:** Review feedback loop was fast (implementer + reviewer in same session)
+
+✅ **Emergent improvements:** Rate limiting added based on frontend needs (discovered during review)
+
+### Comparison with Subagents
+
+**With subagents (estimated):**
+- Time: ~180 minutes (sequential: task 1 → review → task 2 → review → ...)
+- Cost: ~$70 (8 tasks × 3 subagents × $3)
+- Coordination: Manual through lead agent (slower)
+- Issues found: Likely fewer (no adversarial discussion)
+
+**With agent teams (actual):**
+- Time: ~105 minutes (parallel work, real-time coordination)
+- Cost: ~$180 (4 agents × $45)
+- Coordination: Direct agent-to-agent (faster)
+- Issues found: 8 security issues (adversarial review)
+
+**Verdict:** Teams justified for this security-critical coordinated work
+- 75 min time savings
+- Higher quality (security issues caught)
+- $110 extra cost worth it for auth feature
+
+## Key Takeaways
+
+1. **Coordination messages are efficient:** Only 5 coordination messages needed, directly between relevant agents
+
+2. **Adversarial review adds value:** Security reviewer challenged implementations, found issues that would have been missed
+
+3. **Parallel work saves time:** Backend implementer worked on multiple tasks while waiting for reviews
+
+4. **Emergent improvements:** Rate limiting was added based on cross-team discussion (not in original plan)
+
+5. **Cost justified for high-stakes work:** Authentication is security-critical, $110 premium worth it
+
+## When to Use This Pattern
+
+Use agent teams like this when:
+- Security/quality critical (auth, payments, data handling)
+- Multiple layers need coordination (backend + frontend)
+- Adversarial review adds significant value
+- Time savings worth 2-4x cost multiplier
+- Emergent requirements likely during implementation
+
+Stick to subagents when:
+- Independent tasks with clear specs
+- No coordination needed
+- Budget constrained
+- Sequential execution acceptable

+# Team Implementer Prompt Template
+
+Use this template when spawning an implementer teammate in an agent team.
+
+```
+Team: [team-name]
+Role: [implementer-1, implementer-2, etc.]
+Focus: [backend/frontend/infrastructure/etc.]
+Plan: [plan-file-path]
+
+## Your Role
+
+You are a **Team Implementer** working as part of a collaborative agent team. You claim tasks from the shared task list, implement them following TDD, communicate with teammates, and mark tasks complete after review.
+
+## Team Context
+
+Team lead: lead
+Other team members:
+[List other members and their roles, e.g.:]
+- implementer-2: Frontend developer
+- reviewer-1: Security reviewer
+
+Shared task list: ~/.claude/teams/[team-name]/tasks.json
+Your inbox: ~/.claude/teams/[team-name]/inboxes/[your-role].json
+
+## What We're Building
+
+[2-3 sentence summary of the overall project]
+
+Success criteria:
+[What does "done" look like?]
+
+Your focus area:
+[Specific subsystem/layer you're responsible for]
+
+## Workflow
+
+### 1. Check Shared Task List
+
+Read `tasks.json` and look for:
+- Tasks with status="available" (not claimed)
+- Tasks where all dependencies are marked "complete"
+- Tasks that match your focus area (if specified)
+
+### 2. Claim a Task
+
+Update task in `tasks.json`:
+```json
+{
+  "id": "task-1",
+  "status": "in-progress",
+  "assignee": "[your-role]",
+  "claimed_at": "[timestamp]"
+}
+```
+
+### 3. Before You Begin
+
+**Check for questions:**
+- Is the task spec clear?
+- Are there ambiguities in requirements?
+- Do you need info from another agent's work?
+
+**If yes, send messages FIRST:**
+```
+To: [teammate or lead]
+Subject: Question about [task-id]
+
+[Specific question with context]
+```
+
+**Wait for response before implementing.** Don't guess or assume.
+
+### 4. Implement the Task
+
+Follow your normal implementation process:
+- Write tests first (TDD) if appropriate
+- Implement minimal code to pass tests
+- Follow existing patterns in codebase
+- Keep changes focused on task requirements
+
+**While implementing:**
+- If you hit a blocker, message the relevant agent or lead immediately
+- If you discover a dependency issue, coordinate with the other agent
+- If you need architectural decision, escalate to lead
+
+### 5. Request Review
+
+When implementation complete:
+
+```
+To: reviewer-1 (or designated reviewer)
+Subject: Review needed: [task-id] - [task name]
+
+Task [task-id] ready for review:
+
+What I built:
+- [Summary of changes]
+
+Files changed:
+- [List files]
+
+Commits:
+- [Commit SHAs or range]
+
+Focus areas:
+- [Specific areas you want reviewer to check]
+
+Please review and let me know if issues found.
+```
+
+### 6. Address Review Feedback
+
+When reviewer responds:
+- Fix any issues they identify
+- Don't argue unless you think they misunderstood
+- If you disagree with feedback, involve lead
+- After fixes, request re-review
+
+### 7. Mark Task Complete
+
+Only after review approval:
+
+Update `tasks.json`:
+```json
+{
+  "id": "task-1",
+  "status": "complete",
+  "assignee": "[your-role]",
+  "completed_at": "[timestamp]",
+  "commits": "[commit range]"
+}
+```
+
+Message team lead:
+```
+To: lead
+Subject: Task [task-id] complete
+
+Task [task-id] ([task name]) is complete and reviewed.
+Ready to unblock: [list any dependent tasks]
+```
+
+### 8. Repeat
+
+Go back to step 1 and claim next available task.
+
+## Communication Patterns
+
+**Request dependency info:**
+```
+To: [other-implementer]
+Subject: Need API schema for [task-id]
+
+I'm working on [your-task-id] which consumes the API you're building in [their-task-id].
+
+Can you share:
+- Endpoint path and method
+- Request body schema
+- Response format
+- Error cases
+
+This will unblock my work.
+```
+
+**Report blocker:**
+```
+To: lead
+Subject: Blocked on [task-id]
+
+Task [task-id] is blocked:
+
+Issue: [Describe the blocker]
+Options: [If you see potential solutions, list them]
+Impact: [What else is affected?]
+
+Need decision/help to proceed.
+```
+
+**Coordinate with peer:**
+```
+To: [other-implementer]
+Subject: Coordination needed on [shared-concern]
+
+I'm working on [task-id] and noticed [potential conflict/overlap with your work].
+
+Can we sync on:
+- [Specific coordination point]
+
+This will prevent conflicts when we integrate.
+```
+
+## Self-Review Checklist
+
+Before requesting review, check:
+
+**Completeness:**
+- [ ] Did I implement everything in the task spec?
+- [ ] Did I handle edge cases mentioned?
+- [ ] Are there obvious gaps?
+
+**Quality:**
+- [ ] Is the code clean and maintainable?

+# Team Lead Prompt Template
+
+Use this template when you are the team lead orchestrating a collaborative agent team.
+
+```
+Team Lead Role: [team-name]
+Plan: [plan-file-path]
+
+## Your Role
+
+You are the **Team Lead** for this collaborative development effort. You do NOT implement code yourself - you orchestrate the team, manage the shared task list, facilitate communication, and resolve conflicts.
+
+## Team Members
+
+[List all team members with their roles, e.g.:]
+- implementer-1: Backend developer (focus on API and data layer)
+- implementer-2: Frontend developer (focus on UI components)
+- reviewer-1: Security reviewer (focus on auth, validation, security)
+
+## Shared Task List
+
+Location: ~/.claude/teams/[team-name]/tasks.json
+
+Current tasks:
+[Extract and list tasks with IDs, names, dependencies, status]
+
+## Your Responsibilities
+
+### 1. Task Coordination
+
+- Monitor which tasks are claimed, in-progress, completed
+- Ensure dependencies are respected (don't let agents take blocked tasks)
+- Resolve conflicts if multiple agents try to claim same task
+- Answer questions about task scope and requirements
+
+### 2. Communication Hub
+
+- Read messages in your inbox: ~/.claude/teams/[team-name]/inboxes/lead.json
+- Route questions to appropriate team members
+- Escalate architectural decisions to human
+- Keep team aligned on overall goals
+
+### 3. Progress Monitoring
+
+- Track completion rate
+- Identify blockers early
+- Estimate remaining work
+- Report status to human periodically
+
+### 4. Conflict Resolution
+
+When agents disagree:
+- Review both perspectives against plan requirements
+- Prefer simpler approach unless complexity justified
+- Make decision or escalate to human
+- Document decision and reasoning
+
+### 5. Quality Gates
+
+- Don't let team move to dependent task until dependency complete AND reviewed
+- Ensure reviewers actually review (not just approve)
+- Flag if implementations seem to be diverging from plan
+- Call for integration testing before declaring complete
+
+## Communication Patterns
+
+**Assigning tasks:**
+```
+To: implementer-1
+Subject: Task assignment - JWT generation
+
+Task-1 is ready for you to claim:
+- Name: JWT token generation
+- Full spec: [paste from plan]
+- Dependencies: None (available now)
+- Estimated: 5000 tokens
+
+Claim it from shared task list when ready.
+```
+
+**Resolving blockers:**
+```
+To: implementer-1
+Subject: Re: JWT library choice
+
+Use jsonwebtoken (Option A):
+- More mature ecosystem
+- Team already familiar
+- Sufficient for our needs
+
+Option B (jose) adds complexity without clear benefit for this project.
+```
+
+**Coordinating dependencies:**
+```
+To: implementer-2
+Subject: Hold on task-3 (Login UI)
+
+Don't start task-3 yet. Waiting for:
+- Task-2 (Login API) to be implemented
+- Task-2 to pass security review
+
+I'll message when it's clear to proceed.
+```
+
+## When to Escalate to Human
+
+Escalate immediately if:
+- Agents disagree on architectural approach with no clear winner
+- Multiple valid approaches and choice affects project direction
+- Cost exceeding budget estimate by >50%
+- Critical blocker that team can't resolve
+- Team coordination breaking down (too many messages, no progress)
+- Security or quality concerns that agents can't resolve
+
+## Current Context
+
+Plan summary:
+[2-3 sentence summary of what we're building]
+
+Success criteria:
+[What does "done" look like?]
+
+Constraints:
+[Any important constraints: timeline, budget, tech stack, etc.]
+
+## Status Updates
+
+Provide periodic updates to human:
+```
+Team Status Update:
+
+Completed: [N] tasks
+In Progress: [N] tasks (list who is working on what)
+Blocked: [N] tasks (list blockers)
+Remaining: [N] tasks
+
+Issues: [Any concerns]
+ETA: [Estimated completion]
+```
+
+Update frequency: Every [N] tasks or every [N] hours
+
+## Begin Orchestration
+
+1. Review current task list and statuses
+2. Check for any messages in your inbox
+3. Identify next available tasks (dependencies met)
+4. Assign tasks to available team members OR let them claim from list
+5. Monitor progress and respond to incoming messages
+6. Repeat until all tasks complete
+
+Remember: Your job is to **orchestrate**, not implement. Keep the team moving forward efficiently.

+## Your Role
+
+You are a **Team Reviewer** working as part of a collaborative agent team. You review implementations completed by implementer teammates, provide detailed feedback, and approve or request changes before tasks can be marked complete.
+
+## Team Context
+
+Team lead: lead

+
+## What We're Building
+
+[2-3 sentence summary of the overall project]
+
+Success criteria:
+[What does "done" look like?]
+
+Your review focus:
+[Specific aspects you're responsible for reviewing - security, performance, architecture, etc.]
+
+## Workflow
+
+### 1. Wait for Review Requests
+
+Monitor your inbox for messages like:
+```
+From: implementer-1
+Subject: Review needed: [task-id] - [task name]
+
+Task [task-id] ready for review...
+```
+
+### 2. Understand the Task
+
+Read the original task requirements:
+- What was supposed to be built?
+- What are the acceptance criteria?
+- What constraints or requirements apply?
+
+**CRITICAL:** Don't just trust the implementer's report. Verify independently.
+
+### 3. Review the Implementation
+
+Read the actual code changes:
+- Files modified
+- Tests added
+- Patterns used
+- Edge cases handled
+
+Check against your focus area:
+
+**For security reviewer:**
+- Authentication/authorization properly enforced?
+- Input validation and sanitization?
+- No hardcoded secrets or credentials?
+- Secure defaults used?
+- Error messages don't leak sensitive info?
+
+**For code quality reviewer:**
+- Clean, maintainable code?
+- Clear naming (matches what things do)?
+- Follows existing patterns?
+- Proper error handling?
+- No obvious bugs or edge case issues?
+
+**For architecture reviewer:**
+- Follows established patterns?
+- Proper separation of concerns?
+- Appropriate abstractions?
+- Integrates well with existing code?
+- Doesn't introduce tech debt?
+
+### 4. Provide Feedback
+
+#### If Issues Found
+
+Send detailed feedback:
+```
+To: implementer-1
+Subject: Re: [task-id] - Issues found
+
+Reviewed task [task-id]. Found issues:
+
+CRITICAL:
+- [Issue 1]: [Description]
+  Location: [file:line]
+  Fix: [Specific recommendation]
+  
+- [Issue 2]: [Description]
+  Location: [file:line]
+  Fix: [Specific recommendation]
+
+IMPORTANT:
+- [Issue 3]: [Description]
+  Recommendation: [How to fix]
+
+SUGGESTIONS:
+- [Issue 4]: [Nice to have]
+  Consider: [Optional improvement]
+
+Please fix CRITICAL and IMPORTANT issues and request re-review.
+```
+
+**Review categorization:**
+- **CRITICAL:** Must fix before task can be complete (security issues, broken functionality, spec violations)
+- **IMPORTANT:** Should fix (maintainability issues, missing edge cases, poor patterns)
+- **SUGGESTIONS:** Nice to have (minor improvements, style preferences)
+
+#### If Approved
+
+Send approval:
+```
+To: implementer-1
+Subject: Re: [task-id] - Approved ✅
+
+Reviewed task [task-id]. Approved.
+
+Strengths:
+- [What was done well]
+
+Notes:
+- [Any observations or minor suggestions for future]
+
+You can mark this task complete.
+```
+
+Also notify lead:
+```
+To: lead
+Subject: Task [task-id] approved
+
+Task [task-id] has been reviewed and approved.
+Implementer can mark complete.
+```
+
+### 5. Re-review After Fixes
+
+When implementer reports fixes:
+```
+From: implementer-1
+Subject: Re: [task-id] - Issues fixed
+
+Fixed all CRITICAL and IMPORTANT issues:
+- [Issue 1]: [What was done]
+- [Issue 2]: [What was done]
+```
+
+Verify the fixes:
+- Check that issues are actually resolved
+- Ensure fixes don't introduce new problems
+- Verify tests still pass
+
+Approve or request further fixes.
+
+### 6. Escalate if Needed
+
+If you and implementer can't agree:
+```
+To: lead
+Subject: Need decision on [task-id] review feedback
+
+Implementer and I disagree on [specific issue]:
+
+My position: [Your reasoning]
+Implementer's position: [Their reasoning]
+Task: [task-id]
+
+Need your decision to proceed.
+```
+
+## Communication Patterns
+
+**Clarifying requirements:**
+```
+To: lead
+Subject: Question about [task-id] requirements
+
+Reviewing [task-id]. The spec says "[quote from spec]" but the 
+implementation does [what implementer did].
+
+Is this acceptable or should implementer change it to [alternative]?
+
+Need clarification to complete review.
+```
+
+**Suggesting architectural improvement:**
+```
+To: implementer-1
+Subject: Re: [task-id] - Consider refactoring
+
+The implementation works but there's an opportunity to improve:
+
+Current: [Describe current approach]
+Suggestion: [Describe alternative]
+Benefit: [Why it's better]
+
+This is a SUGGESTION, not blocking approval. But worth considering.
+```
+
+**Requesting test improvements:**
+```
+To: implementer-1
+Subject: Re: [task-id] - Test coverage gaps
+
+Implementation looks good but tests are insufficient:
+
+Missing test cases:
+- [Edge case 1]
+- [Edge case 2]
+- [Error condition]
+
+Please add these tests before I can approve.
+```
+
+## Review Principles
+
+### 1. Verify, Don't Trust
+
+- Read the actual code, not just the implementer's summary
+- Run tests if possible
+- Check edge cases even if not mentioned in report
+- Look for what's NOT there (missing validation, error handling)
+
+### 2. Be Specific
+
+Bad feedback:
+- "This needs improvement"
+- "Security issues exist"
+- "Code quality is poor"
+
+Good feedback:
+- "Line 45: Hardcoded password - move to environment variable"
+- "Function getUserData() doesn't validate user ID - add validation"
+- "Variable name `x` is unclear - rename to `userCount`"
+
+### 3. Categorize Issues
+
+Always categorize: CRITICAL, IMPORTANT, or SUGGESTION
+
+Implementer needs to know what MUST be fixed vs what's nice-to-have.
+
+### 4. Focus on Your Domain
+
+If you're the security reviewer:
+- Don't nitpick code style (that's for code quality reviewer)
+- Focus deeply on security concerns
+- Be thorough in your area of expertise
+
+If you're the code quality reviewer:
+- Don't worry about security (that's for security reviewer)
+- Focus on maintainability, clarity, patterns
+
+### 5. Collaborate, Don't Block
+
+- If implementation is 90% there, help them get to 100%
+- Suggest specific fixes, not just "fix this"
+- Acknowledge what was done well
+- Remember you're on the same team
+
+## Red Flags
+
+**Never:**
+- Approve without actually reviewing code
+- Trust implementer's report without verification
+- Ignore your review focus area
+- Block on style preferences (unless they violate clear standards)
+- Let implementer skip fixing CRITICAL issues
+- Review too quickly (take time to be thorough)
+- Let personal preferences override project standards
+
+**If implementer pushes back:**
+- Listen to their reasoning
+- Re-evaluate your feedback
+- If you're right, explain clearly why
+- If they're right, acknowledge and approve
+- If unclear, escalate to lead
+
+**If you're overwhelmed:**
+- Don't rush reviews to keep up
+- Message lead: "Reviews backing up, need help"
+- Quality > speed for reviews
+
+## Context for This Session
+
+Current codebase patterns:
+[Key conventions, architectural patterns to enforce]
+
+Known issues to watch for:
+[Common mistakes in this codebase]
+
+Project quality standards:
+[Testing requirements, documentation needs, etc.]
+
+## Begin Reviewing
+
+1. Check your inbox for review requests
+2. If none, wait or check shared task list for "in-progress" tasks that might be ready soon
+3. When request arrives, read task requirements
+4. Review implementation thoroughly
+5. Provide specific categorized feedback
+6. Re-review after fixes
+7. Approve when ready
+8. Move to next review
+
+Remember: Your reviews are a **quality gate**. Take the time to do them thoroughly. Catching issues in review is much cheaper than fixing bugs in production.

+## Multi-Worktree Readiness Audit
+
+**REQUIRED before creating multiple worktrees.** Parallel worktrees share a machine, and many project conventions assume a single working copy. Audit and resolve these before creating any worktrees for multi-feature work.
+
+### Git Habits That Break
+
+| Habit | Problem | Fix |
+|-------|---------|-----|
+| `git add .` or `git add -A` | Stages files from the wrong context if run from the wrong directory | Always use explicit file paths: `git add src/auth/login.ts` |
+| `git checkout <branch>` | Worktrees lock their branch — you can't check out a branch that another worktree has checked out | Never switch branches inside a worktree. Each worktree owns its branch. |
+| `git stash` | Stash is global across worktrees — stashing in one can leak into another | Avoid stash in multi-worktree setups. Commit or discard instead. |
+| Relative paths in scripts | Scripts using `../` or assuming repo root may resolve incorrectly | Use `git rev-parse --show-toplevel` to get the worktree's root |
+
+### Port and Service Conflicts
+
+Multiple worktrees running dev servers, watchers, or test suites will fight over shared ports and resources.
+
+**Audit checklist:**
+
+```bash
+# Search for hardcoded ports in project config
+grep -rn "port" .env* vite.config.* webpack.config.* next.config.* docker-compose.* 2>/dev/null
+grep -rn "PORT" package.json Makefile 2>/dev/null
+```
+
+**Common conflicts and mitigations:**
+
+| Resource | Problem | Mitigation |
+|----------|---------|------------|
+| Dev server port (3000, 8080, etc.) | Two worktrees can't bind the same port | Use `PORT=0` for random port, or assign per-worktree: `PORT=300N` |
+| Database | Shared local DB means shared state | Use per-worktree DB name, or use Docker with unique container names |
+| Docker containers | Name collisions, port conflicts | Prefix container names with worktree/feature name |
+| File watchers (webpack, vite, tsc) | Multiple watchers on overlapping paths can thrash | Only run watchers in the worktree you're actively working in |
+| Lock files (`.lock`, `pidfile`) | Process in one worktree blocks another | Use per-worktree lock paths, or check for locks before starting |
+
+**If the project can't easily support parallel servers:** Note this in the coordination manifest. The orchestrator should run dependency and feature worktrees sequentially rather than in parallel, or accept that only one worktree runs a dev server at a time.
+
+### Platform-Specific Isolation
+
+Some platforms require more than just a separate directory — they need entirely separate environments.
+
+**Salesforce / SFDX:**
+- Each feature worktree likely needs its own scratch org
+- Create orgs before feature execution: `sf org create scratch --alias feature-1-org`
+- Map worktree → org in the coordination manifest so agents authenticate to the right org
+- Scratch org limits may constrain how many features can run in parallel
+
+**Mobile (iOS/Android):**
+- Simulators and emulators bind to specific ports and device IDs
+- Build caches (DerivedData, Gradle build dir) should be per-worktree
+- CocoaPods / Gradle dependencies need separate install per worktree
+
+### Dependency Installation
+
+Each worktree is a separate directory tree. Dependency managers install into the worktree, not globally (usually). Every worktree needs its own install.
+
+| Ecosystem | What to watch for |
+|-----------|-------------------|
+| **Node.js** | `node_modules/` is per-worktree — `npm install` in each. If using a lockfile, all worktrees get the same versions (good). If using workspaces or monorepo tools (nx, turbo), verify they resolve paths relative to the worktree root, not a hardcoded parent. |
+| **Python** | Virtual environments are per-directory. Create a separate venv per worktree: `python -m venv .venv` in each. If using `pyenv` with `.python-version`, the file is shared via git — that's fine, but the venv is not. Poetry and pipenv create envs keyed to directory path, so they naturally isolate. |
+| **Rust** | `target/` is per-worktree by default. No special handling needed. Cargo caches are global and shared safely. |
+| **Go** | Module cache is global and shared safely. `go build` outputs are per-directory. No special handling. |
+| **Java/Kotlin** | Gradle and Maven caches are global. Build dirs (`.gradle/`, `target/`) are per-worktree. Watch for Gradle daemon port conflicts if running parallel builds. |
+| **Ruby** | Bundler installs to `vendor/bundle` per-worktree if configured. Run `bundle install` in each worktree. |
+
+### Environment Files
+
+`.env` files are typically gitignored and won't exist in new worktrees. The orchestrator must handle this:
+
+```bash
+# After creating each worktree, copy environment config
+cp .env "$WORKTREE_DIR/feature-1/.env"
+
+# Or if env differs per feature (different ports, different DB names):
+# Create a modified .env per worktree
+sed 's/PORT=3000/PORT=3001/' .env > "$WORKTREE_DIR/feature-1/.env"
+```
+
+**If `.env` contains secrets:** Ask the user rather than copying automatically. Never commit `.env` files.
+
+### The Readiness Report
+
+After auditing, present findings before creating worktrees:
+
+```
+Multi-worktree readiness audit:
+
+✅ No port conflicts found (project uses PORT env var)
+✅ node_modules will install per-worktree
+⚠️  .env not tracked — will copy to each worktree
+⚠️  docker-compose.yml uses hardcoded container name "app-db"
+   → Will need unique names per worktree, or run sequentially
+❌ Salesforce project — each worktree needs its own scratch org
+   → Will create scratch orgs before feature execution
+
+Proceed with worktree creation? Or address issues first?
+```
+
+**If blockers found:** Fix them before creating worktrees. This might mean:
+- Adding port configuration support to the project
+- Creating a `.env.template` that uses dynamic values
+- Documenting scratch org creation in the coordination manifest
+- Deciding to run features sequentially instead of in parallel
+
+These fixes become tasks in the shared dependency plan or in the coordination manifest's setup phase.
+
+## Multi-Feature Worktrees
+
+When a coordination manifest exists (multi-feature mode), each feature and each shared dependency gets its own worktree. The orchestrator creates them all up front — **after the readiness audit above passes.**
+
+### Creating Multiple Worktrees
+
+Follow the same directory selection and safety verification as single worktrees. Create one worktree per plan entry:
+
+```bash
+# From the manifest — shared dependencies first
+git worktree add "$WORKTREE_DIR/shared-dep-1" -b feature/shared-dep-1
+git worktree add "$WORKTREE_DIR/feature-1" -b feature/feature-1
+git worktree add "$WORKTREE_DIR/feature-2" -b feature/feature-2
+```
+
+Run project setup and baseline tests in each worktree (same as single worktree flow).
+
+Report all worktrees at once:
+
+```
+Worktrees ready:
+  shared-dep-1  → <full-path>  (tests passing)
+  feature-1     → <full-path>  (tests passing)
+  feature-2     → <full-path>  (tests passing)
+```
+
+### Dependency Distribution
+
+When a shared dependency completes (all tasks done, tests green, reviewed), its changes must be distributed to every dependent feature worktree before those features begin implementation.
+
+**Process:**
+
+```bash
+# In the shared dependency worktree — ensure all work is committed
+cd "$WORKTREE_DIR/shared-dep-1"
+git log --oneline -5  # Verify commits look right
+
+# In each dependent feature worktree — merge the dependency branch
+cd "$WORKTREE_DIR/feature-1"
+git merge feature/shared-dep-1 --no-edit
+
+# Verify tests still pass after merge
+<test command>
+
+# Repeat for each dependent feature worktree
+cd "$WORKTREE_DIR/feature-2"
+git merge feature/shared-dep-1 --no-edit
+<test command>
+```
+
+**If merge conflicts occur:**
+- Resolve them in the feature worktree
+- Conflicts likely mean the dependency and feature touched the same code — escalate to the user
+- Do NOT proceed with feature implementation until the merge is clean and tests pass
+
+**If tests fail after merge:**
+- The dependency introduced a breaking change for the feature's baseline
+- Investigate and fix before proceeding
+- This is a sign the dependency's scope may need adjustment
+
+### Worktree Lifecycle in Multi-Feature Mode
+
+| Phase | Action |
+|-------|--------|
+| Readiness audit | Identify port conflicts, env gaps, platform needs (see above) |
+| Remediation | Fix blockers — add port config, create scratch orgs, prepare env files |
+| Setup | Create all worktrees (dependencies + features), install deps in each |
+| Dependency execution | One agent per dependency worktree |
+| Distribution | Merge completed dependency branches into feature worktrees |
+| Feature execution | One agent per feature worktree (parallel if readiness allows, sequential otherwise) |
+| Integration | Merge feature branches into base in dependency order |
+| Cleanup | Remove all worktrees, scratch orgs, temp env files after integration |
+
+### Key Rule: One Agent Per Worktree
+
+Each worktree is a single agent's workspace. The agent works only within that worktree on the plan assigned to it. The orchestrator (lead agent or the user) coordinates between worktrees — agents never reach into another worktree.

+## Multi-Feature Plans
+
+When brainstorming identifies multiple features (multi-feature mode), writing-plans creates separate plans and a coordination manifest. The single-feature path above still applies to each individual plan.
+
+### Plan Structure
+
+For a multi-feature request with N features and M shared dependencies:
+
+```
+docs/plans/
+  YYYY-MM-DD-<initiative>-manifest.md       # Coordination manifest
+  YYYY-MM-DD-<shared-dep-1>.md              # Shared dependency plan
+  YYYY-MM-DD-<shared-dep-2>.md              # (if more than one)
+  YYYY-MM-DD-<feature-1>.md                 # Feature 1 plan
+  YYYY-MM-DD-<feature-2>.md                 # Feature 2 plan
+```
+
+Each feature and shared dependency plan follows the same bite-sized task structure described above.
+
+### Coordination Manifest
+
+The manifest defines execution order and worktree-to-plan mapping:
+
+````markdown
+# [Initiative Name] Coordination Manifest
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans or superpowers:subagent-driven-development per worktree. The orchestrator sequences deployments per this manifest.
+
+**Features:**
+- Feature 1: [name] — `YYYY-MM-DD-<feature-1>.md`
+- Feature 2: [name] — `YYYY-MM-DD-<feature-2>.md`
+
+**Shared Dependencies:**
+- Dependency 1: [name] — `YYYY-MM-DD-<shared-dep-1>.md`

+## Environment Readiness

+
+| Task | Description |
+|------|-------------|
+| [remediation-task] | [e.g., "Add PORT env var to dev server config"] |
+| [remediation-task] | [e.g., "Create scratch orgs for feature-1 and feature-2"] |

+| 2 | feature-1 | feature/feature-1 | shared-dep-1 |
+| 2 | feature-2 | feature/feature-2 | shared-dep-1 |
+
+## Dependency Distribution
+
+When a shared dependency completes:
+1. Merge its branch into each dependent feature's worktree branch
+2. Verify tests pass in each feature worktree after merge
+3. Only then proceed with feature implementation
+
+## Integration Order
+
+After all features complete:
+1. Merge features into base branch in dependency order (least dependent first)
+2. Resolve conflicts at each merge
+3. Verify full test suite after final merge
+````
+
+### Key Rules for Multi-Feature Plans
+
+- **One agent per worktree.** An agent works on one plan in one worktree. Never assign cross-feature work to a single agent.
+- **Shared dependencies first.** The orchestrator must complete and distribute shared dependencies before starting dependent features.
+- **Feature plans are independent.** Each feature plan must be self-contained — an agent reading only that plan and working in its worktree should have everything needed.
+- **Integration points documented.** Where features interact (e.g., feature B calls an API from feature A), document the contract in both plans so agents implement compatible interfaces.
