petit-poucet

Leaves pebbles so your coding agents find their way back.

In the French tale *Le Petit Poucet*, a boy drops white pebbles along the path so he can find his way home. **petit-poucet** does the same for AI coding agents: it keeps a small, curated memory of your rules, decisions and verified facts, so every new session in Claude Code, GitHub Copilot CLI or any MCP client starts where the last one left off.

Why

Coding agents forget everything between sessions, and each tool keeps its own memory in its own format. petit-poucet gives them one shared memory that:

• is plain Markdown: a folder of notes you can read and edit in Obsidian or any editor; no database, no cloud;
• is curated, not recorded: agents save a decision, a correction or a verified fact deliberately, with its source; nothing is captured from transcripts;
• enforces its own rules: note format, Index and links are checked by the server, not left to each agent's good will;
• protects what you said: rules you stated are never changed or deleted without your confirmation;
• keeps history: the vault is a git repository with a local commit after every change, so any agent edit can be inspected and undone;
• is one small binary: written in Rust, no runtime to install.

What your agent sees

At the start of every session, a hook gives the agent the memo
