warden
Your code is under new management. Agents that review your code - locally or on every PR - using the Skills you already know and love.
Why Warden?
Skills, not prompts. Define analysis once, run it anywhere. Bootstrap your environment with skills from conventional directories (.agents/skills/ or .claude/skills/).
Two ways to run. CLI catches issues before you push. GitHub Action reviews every PR automatically.
GitHub-native. Eligible findings appear as inline PR comments with suggested fixes, and every finding is reported in Checks.
