+# AI Enhancement Features for OpenCode
+
+## Overview
+This contribution adds three AI-powered features to OpenCode, each with working implementations and passing tests.
+
+## Features
+
+### 1. Swarm Intelligence (`swarm-functional.ts`)
+Coordinates multiple agents to work on tasks in parallel.
+
+**What it does:**
+- Decomposes tasks into subtasks
+- Executes subtasks in parallel (up to 3 concurrent)
+- Manages dependencies between tasks
+- Selects appropriate agents based on capabilities
+
+**Tests:** 5 passing
+
+### 2. Semantic Memory (`semantic-memory-functional.ts`)
+Persists learned patterns, decisions, and bug history across sessions.
+
+**What it does:**
+- Saves data to `.opencode/semantic-memory.json`
+- Learns code patterns with frequency tracking
+- Detects conflicting decisions
+- Tracks bug history with solutions
+- Bounded storage (max 100 decisions, 50 bugs)
+
+**Tests:** 8 passing
+
+### 3. Code Review Tool (`review-functional.ts`)
+Performs static analysis on code files.
+
+**What it does:**
+- **Security checks:** SQL injection, XSS, path traversal, hardcoded credentials, eval usage
+- **Performance checks:** Nested loops, sync I/O, string concatenation
+- **Quality checks:** Complexity metrics, magic numbers, debug code
+- Generates scored reports with recommendations
+
+**Tests:** 6 passing
+
+### 4. Predictive Engine (`engine-functional.ts`)
+Analyzes code patterns to make predictions.
+
+**What it does:**
+- Pattern-based code predictions
+- Missing import detection
+- Bug prediction from history
+- File analysis for improvements
+
+**Tests:** Not yet implemented
+
+## Test Results
+
+Run tests with:
+```bash
+cd packages/opencode
+bun test test/agent/swarm-functional.test.ts
+bun test test/session/semantic-memory-functional.test.ts
+bun test test/tool/review-functional.test.ts
+```
+
+**Results:** 19 tests passing, 0 failing
+
+## Technical Details
+
+- **Language:** TypeScript
+- **File I/O:** Uses `fs/promises` for async operations
+- **Error Handling:** Try-catch blocks throughout
+- **Memory Management:** Bounded data structures
+- **Testing:** Bun test framework
+

+```
+
+**Total:** ~1,400 lines of code + tests
+
+## Usage Examples
+
+### Swarm Intelligence
+```typescript
+import { FunctionalSwarmOrchestrator } from '@/agent/swarm-functional'
+
+const orchestrator = new FunctionalSwarmOrchestrator(3)
+const tasks = FunctionalSwarmOrchestrator.decomposeTask(
+  "refactor authentication module",
+  { module: "auth" }
+)
+const result = await orchestrator.execute(tasks, sessionID)
+```
+
+### Semantic Memory
+```typescript
+import { FunctionalSemanticMemory } from '@/session/semantic-memory-functional'
+
+const memory = new FunctionalSemanticMemory()
+await memory.load()
+await memory.learnPattern("const x = await fetch(...)", "async pattern")
+const patterns = memory.recallPatterns("fetch", 5)
+await memory.autoPersist()
+```
+
+### Code Review
+```typescript
+import { FunctionalReviewTool } from '@/tool/review-functional'
+
+const review = await FunctionalReviewTool.init()
+const result = await review.execute({
+  filePath: "src/auth/login.ts",
+  focusAreas: ["security", "performance", "quality"]
+}, ctx)
+```
+
+## Integration
+
+These features are designed to integrate with OpenCode's existing:
+- Tool registry
+- Agent system
+- Session management
+- Logging infrastructure
+
+## Limitations
+
+- Predictive engine has no tests yet
+- Pattern matching is regex-based, not AST-based
+- No ML models, uses heuristics
+- Limited to TypeScript/JavaScript analysis
+
+## Future Improvements
+
+- Add AST-based analysis for better accuracy
+- Implement ML models for predictions
+- Add support for more languages
+- Expand security check coverage
+- Add performance benchmarks
+
+## Contributing
+
+All code follows OpenCode conventions and uses existing infrastructure where possible.
