Agent Booster Integration Complete ✅

Summary

Agent Booster v0.2.1 is now fully integrated into agentic-flow with critical strategy fix applied.

What Was Fixed

1. Strategy Selection Bug (v0.1.2 → v0.2.1)

Problem: var→const created duplicates instead of replacing

Before (v0.1.2):

// Input
var x = 1;

// Output (BROKEN - duplicate!)
var x = 1;

const x = 1;

After (v0.2.1):

// Input
var x = 1;

// Output (FIXED - replaced!)
const x = 1;

Root Cause: Strategy thresholds too conservative in merge.rs:

FuzzyReplace required 80%+ similarity
var→const has 57% similarity
Got InsertAfter instead of FuzzyReplace

Fix: Lowered thresholds in crates/agent-booster/src/merge.rs:74-82:

// BEFORE
s if s >= 0.95 => MergeStrategy::ExactReplace,
s if s >= 0.80 => MergeStrategy::FuzzyReplace,
s if s >= 0.60 => MergeStrategy::InsertAfter,

// AFTER
s if s >= 0.90 => MergeStrategy::ExactReplace,
s if s >= 0.50 => MergeStrategy::FuzzyReplace,  // Now catches var→const!
s if s >= 0.30 => MergeStrategy::InsertAfter,

2. WASM Files Missing from npm Package

Problem: Package only 28KB (should be 469KB)

Fix: Removed blocking wasm/.gitignore file containing *

Result: Package now includes 1.3MB WASM module

3. Express Dependency Missing

Problem: agent-booster-server requires express but it was in devDependencies

Fix: Moved express to dependencies in package.json

Integration Points

✅ 1. MCP Tools (Live in v1.4.2)

Location: agentic-flow/src/mcp/standalone-stdio.ts

Tools:

agent_booster_edit_file - Single file editing
agent_booster_batch_edit - Multi-file refactoring
agent_booster_parse_markdown - Parse LLM markdown

Updated: All npx calls now use agent-booster@0.2.1

Usage (Claude Desktop/Cursor):

User: Use agent_booster_edit_file to convert var to const in utils.js
Claude: ✅ Successfully edited utils.js (10ms, 64% confidence)

✅ 2. API Server (Live)

Location: agent-booster/src/server.ts

Endpoints:

POST /v1/chat/completions - Morph LLM compatible
POST /v1/apply - Direct apply
POST /v1/batch - Batch processing

Status: Running on port 3002 with v0.2.1 WASM

Test:

curl -X POST http://localhost:3002/v1/apply \
  -H "Content-Type: application/json" \
  -d '{"code":"var x = 1;","edit":"const x = 1;","language":"javascript"}'

# Response:
{
  "strategy": "fuzzy_replace",
  "confidence": 0.6386110782623291,
  "output": "const x = 1;"
}

🚧 3. Proxy Integration (Proposed)

Goal: Intercept Anthropic SDK tool calls to use Agent Booster transparently

Status: Documented in agentic-flow/docs/AGENT-BOOSTER-INTEGRATION.md

Implementation: Requires changes to src/proxy/anthropic-to-openrouter.ts

🚧 4. CLI Agent Integration (Proposed)

Goal: Pre-process agent tasks with Agent Booster before LLM

Status: Documented in agentic-flow/docs/AGENT-BOOSTER-INTEGRATION.md

Implementation: Requires changes to src/agents/claudeAgent.ts

Test Results

CLI Tests (v0.2.1)

# Test 1: var → const
echo '{"code":"var x = 1;","edit":"const x = 1;"}' | \
  node dist/cli.js apply --language javascript
# ✅ strategy: fuzzy_replace, confidence: 64%

# Test 2: Add type annotations
echo '{"code":"function add(a, b) { return a + b; }","edit":"function add(a: number, b: number): number { return a + b; }"}' | \
  node dist/cli.js apply --language typescript
# ✅ strategy: fuzzy_replace, confidence: 64%

# Test 3: Error handling
echo '{"code":"function divide(a, b) { return a / b; }","edit":"function divide(a, b) { if (b === 0) throw new Error(\\"Division by zero\\"); return a / b; }"}' | \
  node dist/cli.js apply --language javascript
# ✅ strategy: exact_replace, confidence: 90%

Remote Package Test (npm)

cd /tmp && echo '{"code":"var x = 1;","edit":"const x = 1;"}' | \
  npx --yes agent-booster@0.2.1 apply --language javascript
# ✅ Works remotely with fuzzy_replace

API Server Test

curl -X POST http://localhost:3002/v1/apply \
  -H "Content-Type: application/json" \
  -d '{"code":"var x = 1;","edit":"const x = 1;","language":"javascript"}'
# ✅ strategy: fuzzy_replace, confidence: 64%

How to Use

Method 1: MCP Tools (Claude Desktop/Cursor)

User: Use agent_booster_edit_file to convert all var declarations to const in src/utils.js

Claude: [Calls MCP tool]
✅ Successfully edited src/utils.js
   - Latency: 10ms
   - Confidence: 64%
   - Strategy: fuzzy_replace

Method 2: Direct API

# Start server
npx agent-booster-server

# Apply edit
curl -X POST http://localhost:3000/v1/apply \
  -H "Content-Type: application/json" \
  -d '{
    "code": "var x = 1;",
    "edit": "const x = 1;",
    "language": "javascript"
  }'

Method 3: CLI

# Single edit
echo '{"code":"var x = 1;","edit":"const x = 1;"}' | \
