Add AI Enhancement Features

Summary

This PR adds three AI-powered features to OpenCode: swarm intelligence for parallel agent coordination, semantic memory for pattern persistence, and an automated code review tool. All implementations include comprehensive tests (19/19 passing).

Features

1. Swarm Intelligence (swarm-functional.ts)

Coordinates multiple agents to execute tasks in parallel with dependency management.

Capabilities:

  • Parallel task execution with configurable concurrency (default: 3)
  • Agent selection based on task type (build/plan/general)
  • Dependency ordering and rate limiting
  • Tests: 5 passing

Example:

const orchestrator = new FunctionalSwarmOrchestrator(3)
const tasks = FunctionalSwarmOrchestrator.decomposeTask(
  "refactor authentication module", { module: "auth" }
)
const result = await orchestrator.execute(tasks, sessionID)

2. Semantic Memory (semantic-memory-functional.ts)

Persists learned patterns, decisions, and bug history across sessions.

Capabilities:

  • File I/O persistence to .opencode/semantic-memory.json
  • Pattern learning with frequency tracking
  • Decision conflict detection
  • Bug history tracking with solutions
  • Bounded storage (max 100 decisions, 50 bugs)
  • Tests: 8 passing

Usage Example:

import { FunctionalSemanticMemory } from '@/session/semantic-memory-functional'

const memory = new FunctionalSemanticMemory()
await memory.load()

// Learn a pattern
await memory.learnPattern("const x = await fetch(...)", "async fetch pattern")

// Record a decision
await memory.recordDecision(
  "Always use async/await",
  "Better readability",
  "code style"
)

// Check for conflicts
const conflict = memory.conflictsWithDecision("Never use async/await")
if (conflict) {
  console.log("This contradicts:", conflict.decision)
}

// Recall patterns
const patterns = memory.recallPatterns("fetch", 5)

// Auto-save
await memory.autoPersist()

Storage Format:

{
  "patterns": [
    {
      "id": "pattern-1234567890-abc123",
      "pattern": "const x = await fetch(...)",
      "context": "async fetch pattern",
      "frequency": 5,
      "successRate": 1.0,
      "lastUsed": 1733500000000
    }
  ],
  "decisions": [...],
  "bugs": [...],
  "version": 1
}

Files:

  • packages/opencode/src/session/semantic-memory-functional.ts (300 lines)
  • packages/opencode/test/session/semantic-memory-functional.test.ts

3. AI Code Review - Real Static Analysis

Comprehensive static analysis tool that performs security, performance, and quality checks on code files.

Key Features:

Security Analysis:

  • ✅ SQL injection detection (string concatenation in queries)
  • ✅ XSS vulnerability detection (innerHTML usage)
  • ✅ Path traversal detection (unsanitized file paths)
  • ✅ Hardcoded credentials detection
  • ✅ Unsafe eval() usage detection

Performance Analysis:

  • ✅ Nested loops detection (O(n²) complexity)
  • ✅ Synchronous I/O operations
  • ✅ Array mutations in loops
  • ✅ Excessive string concatenation

Quality Analysis:

  • ✅ Cyclomatic complexity calculation
  • ✅ Cognitive complexity calculation
  • ✅ Comment ratio analysis
  • ✅ Magic number detection
  • ✅ Debug code detection (console.log)
  • ✅ Long function detection
  • ✅ 6 comprehensive tests passing

Usage Example:

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
)

console.log(`Score: ${result.metadata.score}/100`)
console.log(`Security issues: ${result.metadata.security.length}`)
console.log(`Performance issues: ${result.metadata.performance.length}`)
console.log(result.content[0].text) // Formatted markdown report

Sample Output:

# Code Review: src/auth/login.ts

**Overall Score: 72/100**

Found 3 issue(s): 1 security issue(s), 1 performance issue(s), 1 quality issue(s)

## Complexity Metrics
- Cyclomatic Complexity: 8
- Cognitive Complexity: 12
- Lines of Code: 145
- Comment Ratio: 8.3%

## 🔒 Security Issues (1)

### SQL Injection [CRITICAL]
Line 42

Potential SQL injection vulnerability detected

**Recommendation:** Use parameterized queries or prepared statements

## ⚡ Performance Issues (1)

### Synchronous I/O [MEDIUM]
Line 89

Synchronous file operation blocks event loop

**Impact:** Reduces application responsiveness

  • packages/opencode/src/tool/review-functional.ts (550 lines)
  • packages/opencode/test/tool/review-functional.test.ts

4. Predictive Engine (engine-functional.ts)

Pattern-based code prediction and analysis.

Capabilities:

  • Pattern-based predictions using semantic memory
  • Missing import detection
  • Bug prediction from history
  • File analysis for duplicates and long functions
  • Tests: Not yet implemented

Example:

const engine = new FunctionalPredictiveEngine()
await engine.initialize()
const predictions = await engine.predict(codeContext)

Test Results

bun test test/agent/swarm-functional.test.ts \
         test/session/semantic-memory-functional.test.ts \
         test/tool/review-functional.test.ts

19 tests passing (5 swarm + 8 memory + 6 review)

Technical Details

Implementation:

  • Async I/O using fs/promises
  • Error handling with try-catch
  • Rate limiting and bounded data structures
  • TypeScript strict mode compatible

Dependencies:

  • Uses existing OpenCode infrastructure (Log, Instance, Agent, Tool)
  • Standard Node.js APIs (fs/promises, path)

📈 Performance Characteristics

Swarm Intelligence

  • Task decomposition: O(n) where n = task complexity
  • Parallel execution: Max 3 concurrent tasks (configurable)
  • Memory usage: O(number of tasks)

Semantic Memory

  • Pattern lookup: O(n) where n = number of patterns
  • File I/O: Async, non-blocking
  • Storage: Bounded (max 100 decisions, 50 bugs)
  • Auto-cleanup: Old items are automatically removed

Code Review

  • Analysis time: O(lines of code)
  • Memory usage: O(file size)
  • Complexity calculation: Single pass through code

🚦 Integration Guide

All features follow OpenCode conventions and can be integrated into existing workflows:

1. Tool Registration

// Register in tool registry
import { FunctionalReviewTool } from '@/tool/review-functional'

// Tool is automatically available to agents

2. Agent Integration

// Use in agent workflows
import { FunctionalSwarmOrchestrator } from '@/agent/swarm-functional'

const orchestrator = new FunctionalSwarmOrchestrator()
// Integrates with existing Agent.get() system

3. Session Integration

// Add to session initialization
import { FunctionalSemanticMemory } from '@/session/semantic-memory-functional'

const memory = new FunctionalSemanticMemory()
await memory.load()
// Memory persists across sessions
