+# Full Autonomous Bounty-Hunting Agent
+
+This is a complete implementation of the T3 bounty: Full Autonomous Bounty-Hunting Agent.
+
+## What This Does
+
+An autonomous multi-agent system that:
+1. **Discovers** open bounties on GitHub across configured repositories
+2. **Analyzes** requirements using LLM planning  
+3. **Implements** solutions with full test coverage
+4. **Validates** through CI/CD checks
+5. **Submits** properly formatted PRs autonomously
+
+## Architecture

+## Key Components
+
+- **Scanner**: Finds bounty-labeled issues via GitHub API
+- **Analyzer**: Uses LLM to create implementation plans
+- **Coder**: Implements code across multiple files
+- **Tester**: Runs tests and validates output
+- **PRSubmitter**: Creates properly formatted PRs
+

+# Full Autonomous Bounty-Hunting Agent
+
+**Repository:** SolFoundry/solfoundry  
+**Bounty:** [T3: Full Autonomous Bounty-Hunting Agent](https://github.com/SolFoundry/solfoundry/issues/861)  
+**Reward:** 1M $FNDRY
+
+## Overview
+
+An autonomous multi-agent system that:
+1. **Discovers** open bounties on GitHub across configured repositories
+2. **Analyzes** requirements using LLM planning
+3. **Implements** solutions with full test coverage
+4. **Validates** through CI/CD checks
+5. **Submits** properly formatted PRs autonomously
+
+The system uses a **planner → executor → reviewer** loop, with each phase handled by specialized agents coordinated through a shared state store.

+
+## Running
+
+```bash
+# Install
+npm install
+
+# Configure
+cp .env.example .env
+# Edit .env with your API keys
+
+# Run once
+npm run hunter
+
+# Run continuously (check every 30 minutes)

+
+## Test Coverage
+

+
+## Summary
+
+This agent:
+- ✅ Scans multiple repositories for bounty issues automatically
+- ✅ Uses LLM planning to analyze requirements and create implementation plans
+- ✅ Implements code across multiple files following repository patterns
+- ✅ Runs tests and validates output
+- ✅ Submits properly formatted PRs with semantic commit messages
+- ✅ Persists state across runs (survives restarts)
+- ✅ Handles errors gracefully with retry logic
+- ✅ Comments on issues to claim the bounty
