Why Lean Agent Kit?

View on GitHub

Start every session with context

Your agent gets a map of the codebase, project conventions, and an active resume note instead of rediscovering the repository from scratch.

Get more consistent results

Keep architecture decisions, commands, constraints, and team conventions where any file-reading coding agent can follow them.

Turn mistakes into lasting improvements

Capture useful discoveries and avoidable failures as learnings, then promote the rules that should guide every future session.

Use only what earns its place

Begin with a small Markdown core. Add packs for specs, stacks, guardrails, and integrations only when your workflow needs them.

Keep your tools and your freedom

Works with Cursor, Claude Code, Copilot, ChatGPT, Aider, Cline, and other file-reading agents. No account, subscription, or lock-in.

Free and open source forever
