Lean Agent KitMemory + guardrails for AI coding agents

Give your agent a persistent Markdown brain — tool-agnostic, brownfield-first, and context-frugal.

Brownfield-first

Maps and learns from the code already in your repo — not a greenfield spec factory.

Agents read CODEBASE_MAP.md and ACTIVE_CONTEXT.md, then open only the files they need.

Works with Cursor, Claude Code, Copilot, ChatGPT, Aider, Cline — anything that can read files.

leanagentkit-check enforces AGENTS.md conventions and stack playbooks on every change.
