## Common Patterns Across All Scenarios

### ✅ Positive Patterns

1. **Security by Default**
   - Minimal permissions (read-only unless write needed)
   - Network restrictions (defaults or firewall)
   - Timeouts set appropriately (15-30 min)
   - SHA-pinned actions where used

2. **Comprehensive Documentation**
   - 4/6 scenarios: 50KB+ documentation suites
   - Always includes: setup, examples, customization
   - Often includes: quickref, architecture, troubleshooting

3. **Error Handling Excellence**
   - Multi-phase workflows continue on non-critical failures
   - Graceful degradation documented
   - Clear error messages with next steps
   - Never blocks users unnecessarily

4. **Production-Ready Outputs**
   - All workflows immediately deployable
   - Real-world patterns and queries
   - Framework-specific guidance
   - Professional formatting

5. **Safe-Output Sophistication**
   - Smart use of max limits (10 issues/run)
   - Grouping for related items
   - Custom messages for UX
   - Update-existing to avoid spam

### 🔍 Areas for Improvement

1. **Documentation Consistency** (Priority: Medium)
   - 2/6 scenarios had less extensive docs (DO-3, SEC-1)
   - SEC-1 response claimed docs not found
   - Inconsistency across scenarios

2. **Documentation Accuracy** (Priority: High)
   - SEC-1: Agent said "70+ pages created" but only workflow file exists
   - Need verification step after file creation

3. **Modern Configuration** (Priority: Low)
   - DO-3 uses older MCP `http` type
   - Should use `remote` or `local` modes

4. **Optimization Guidance** (Priority: Low)
   - Missing caching suggestions for npm workflows
   - Could mention browser caching for Playwright (FE-4)

---

## Recommendations

### For Agent Enhancement

1. **Documentation Consistency Template**
   ```
   For all scenarios, create:
   - README.md (setup guide)
   - QUICKREF.md (daily operations)
   - EXAMPLE.md (sample output)
   - Minimum 20KB total documentation
   ```

2. **Documentation Verification**
   ```
   After claiming file creation:
   - List files created with `ls` command
   - Verify file sizes match claims
   - Include actual file list in response
   ```

3. **Modern Configuration Defaults**
   ```yaml
   # Prefer modern MCP server config
   tools:
     github:
       mode: remote  # Not http type
       toolsets: [default]
   ```

4. **Optimization Checklist**
   ```
   For npm-based workflows, mention:
   - Node modules caching
   - Playwright browser caching
   - Dependency lock file strategies
   ```

### For Future Testing Sessions

1. **Monorepo Scenarios**
   - Test workflows targeting specific packages
   - Path filtering complexity
   - Cross-package dependency analysis

2. **Approval Gate Workflows**
   - Required reviewer logic
   - CODEOWNERS integration
   - Multi-stage approval processes

3. **External Integration**
   - Jira ticket creation
   - Slack notifications
   - PagerDuty incident management
   - ServiceNow integration

4. **Custom Container Workflows**
   - Docker-based agents
   - Custom tool installations
   - Multi-container setups

5. **Matrix and Parallel Execution**
   - Multi-OS testing
   - Multi-version testing
   - Fan-out/fan-in patterns
