CodeRabbit Config Generator

A Claude Code skill that analyzes your project's PR history and commit messages to generate a .coderabbit.yaml tailored to the issues you actually see in practice.

Install

Clone this repo into your Claude Code skills directory:

git clone https://github.com/alchemiststudiosDOTai/coderabbit-config-generator.git \
  ~/.claude/skills/coderabbit-config-generator

The skill is now available in all your projects.

Usage

Ask Claude to run the skill on your current repository:

Run the CodeRabbit config generator skill for this repo using the last 90 days of PRs and commits.

Or invoke it directly:

/coderabbit-config-generator

The skill will:

1. Pull recent PRs and commits via the GitHub CLI
2. Scan for recurring patterns (common issues, edge cases, anti-patterns)
3. Generate a .coderabbit.yaml with custom review checks matched to your project

Prerequisites

• GitHub CLI (gh) authenticated
• Python 3
• A local git clone of the repository you want to analyze

Running the scripts directly

~/.claude/skills/coderabbit-config-generator/scripts/run_analysis.sh \
  --repo-path /path/to/repo --repo owner/name

Validating a config

Requires PyYAML (pip install pyyaml):

python3 ~/.claude/skills/coderabbit-config-generator/scripts/validate_coderabbit_yaml.py \
  --config .coderabbit.yaml

Tuning patterns

Edit scripts/patterns.json to add or refine keyword and regex matches used during analysis.
