CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

Gru is a local-first LLM agent orchestrator that autonomously works on GitHub issues using Claude Code. It manages "Minions" (agent sessions) that claim issues, implement fixes, create PRs, and respond to reviews.

Current Phase: V1 - Basic delegation to Claude Code CLI Language: Rust Architecture: Single binary, GitHub as state store, git worktrees for isolation

Pre-commit Hooks

The project uses git hooks from .githooks/ that automatically run:

• Code formatting check (just fmt-check)
• Linting (just lint)
• Tests (just test)
• Branch protection (blocks commits to main)
• TODO/FIXME warnings (non-blocking)

To enable hooks:

git config core.hooksPath .githooks

When pre-commit hooks fail:

1. Fix the issues using the suggested commands (e.g., just fmt or just fix-clippy)
2. Review the diff with git diff to see what changed
3. Stage the fixed files selectively with git add <files>
4. Never use git add . or git add -A - always stage files explicitly
5. Example workflow:

   git commit -m "Fix bug"
   # Pre-commit hook fails with formatting errors
   just fmt
   git diff              # Review what changed
   git add src/main.rs   # Stage only the files you want to commit
   git commit -m "Fix bug"
   

To bypass in emergencies:

git commit --no-verify
