🎯 What is Agent Booster?
Agent Booster is a local code transformation engine built with Rust and WebAssembly that performs mechanical code edits without calling expensive LLM APIs. It's designed for operations where you know exactly what changes to make—no AI reasoning required.
The Problem
Traditional AI coding agents call LLM APIs for every single code edit, even simple mechanical transformations like:
- Renaming variables across files
- Adding import statements
- Updating function signatures
- Reformatting code blocks
- Find-and-replace operations
Cost: $0.01 per edit Latency: 352ms per edit (API roundtrip) For 1000 edits: $10 + 5.87 minutes
The Solution
Agent Booster performs these operations locally using Rust/WASM:
Cost: $0.00 per edit Latency: 1ms per edit (local execution) For 1000 edits: $0.00 + 1 second
Savings: 352x faster, 100% free, zero API dependency
🚀 How It Works
Agent Booster operates in three modes:
1. Single File Edit (Simple)
Apply precise edits to one file using marker syntax:
npx agentic-flow agent-booster edit \
--file src/api.ts \
--instructions "Add error handling to fetchUser" \
--code '
export async function fetchUser(id: string) {
// ... existing code ...
try {
const response = await fetch(`/api/users/${id}`);
if (!response.ok) throw new Error("User not found");
return await response.json();
} catch (error) {
console.error("Failed to fetch user:", error);
throw error;
}
}
'
2. Batch Edit (Efficient)
Apply multiple edits in a single operation:
npx agentic-flow agent-booster batch \
--config batch-edits.json
batch-edits.json:
{
"edits": [
{
"file": "src/user.ts",
"instructions": "Add type annotation",
"code": "const user: User = { ... }"
},
{
"file": "src/api.ts",
"instructions": "Add error handling",
"code": "try { ... } catch { ... }"
}
]
}
3. Markdown Parse (LLM-Compatible)
Parse LLM-generated markdown with filepath and instruction metadata:
filepath=src/user.ts instruction="Add type annotation"
\`\`\`typescript
const user: User = {
id: string;
name: string;
};
\`\`\`
filepath=src/api.ts instruction="Add error handling"
\`\`\`typescript
try {
// API call
} catch (error) {
console.error(error);
}
\`\`\`

🎯 Use Cases
✅ Perfect For (Use Agent Booster)
Variable Renaming Across Files
# Before: getUserData → fetchUserProfile
# 50 files, 200 occurrences
# LLM: 70 seconds, $2.00
# Agent Booster: 0.2 seconds, $0.00
Adding Import Statements
# Add "import { z } from 'zod'" to 100 TypeScript files
# LLM: 35 seconds, $1.00
# Agent Booster: 0.1 seconds, $0.00
Code Formatting
# Reformat 1000 files to match style guide
# LLM: 5.87 minutes, $10.00
# Agent Booster: 1 second, $0.00
Function Signature Updates
# Update function(a, b) → function(a: string, b: number)
# 30 functions across 10 files
# LLM: 10.5 seconds, $0.30
# Agent Booster: 0.03 seconds, $0.00
❌ Not Suitable For (Use LLM)
Complex Refactoring - Requires reasoning about code structure Bug Fixes - Needs understanding of root cause Feature Implementation - Requires creative problem-solving Architecture Changes - Needs high-level decision making
🔧 Installation & Setup
Prerequisites
- Node.js ≥18.0.0
- Rust toolchain (for building from source)
- WASM support
Quick Start
# Install agentic-flow (includes Agent Booster)
npm install -g agentic-flow
# Verify installation
npx agentic-flow agent-booster --version
# Test with sample edit
npx agentic-flow agent-booster edit \
--file test.ts \
--instructions "Add console.log" \
--code 'console.log("Hello, Agent Booster!");'
MCP Tool Integration
Agent Booster is available as an MCP tool within agentic-flow:
// Use via MCP
await query({
mcp: {
server: 'agentic-flow',
tool: 'agent_booster_edit_file',
params: {
target_filepath: 'src/api.ts',
instructions: 'Add error handling',
code_edit: '// ... code with markers ...'
}
}
});
📖 Advanced Usage
Pattern Matching with Markers
Use // ... existing code ... markers to preserve unchanged sections:
// Original file: src/api.ts
export function fetchUser(id: string) {
return fetch(`/api/users/${id}`);
}
// Edit with markers:
export async function fetchUser(id: string) {
// ... existing code ...
try {
const response = await fetch(`/api/users/${id}`);
if (!response.ok) throw new Error("User not found");
return await response.json();
} catch (error) {
console.error(error);
throw error;
}
}
Multi-File Refactoring
Scenario: Rename getUserData to fetchUserProfile across 50 files
npx agentic-flow agent-booster batch-rename \
--pattern "getUserData" \
--replacement "fetchUserProfile" \
--glob "src/**/*.ts"
Results:
- Files processed: 50
- Occurrences replaced: 187
- Time: 150ms
- Cost: $0.00
Integration with LLM Agents
Combine Agent Booster with LLM agents for optimal performance:
// 1. LLM designs the edits (reasoning)
const edits = await query({
prompt: "Design refactoring for error handling",
agent: "system-architect"
});
// 2. Agent Booster applies the edits (fast execution)
await query({
mcp: {
server: 'agentic-flow',
tool: 'agent_booster_batch_edit',
params: { edits: edits.plan }
}
});
Result: Reasoning time + 1ms execution vs. LLM for every edit

📈 ROI Calculator
Scenario 1: Code Review Agent (100 reviews/day)
Without Agent Booster (LLM for all edits):
- 100 reviews × 10 edits each = 1000 edits/day
- Time: 1000 × 352ms = 5.87 minutes/day
- Cost: 1000 × $0.01 = $10/day = $300/month
With Agent Booster:
- Time: 1000 × 1ms = 1 second/day
- Cost: $0/day = $0/month
Savings: $300/month + 5.86 minutes/day
Scenario 2: Codebase Migration (1000 files)
Without Agent Booster:
- 1000 files × 352ms = 5.87 minutes
- Cost: 1000 × $0.01 = $10
With Agent Booster:
- 1000 files × 1ms = 1 second
- Cost: $0
Savings: 5.85 minutes + $10 per migration
Scenario 3: Refactoring Pipeline (weekly)
Without Agent Booster:
- 50 files/week × 20 edits = 1000 edits/week
- Time: 5.87 minutes/week × 52 = 5.1 hours/year
- Cost: $10/week × 52 = $520/year
With Agent Booster:
- Time: 52 seconds/year
- Cost: $0/year
Savings: 5.1 hours/year + $520/year
