# Napkin A skill for Claude Code that gives the agent persistent memory of its mistakes. The agent maintains a markdown file in your repo (`.claude/napkin.md`) where it tracks what went wrong, what you corrected, and what worked. It reads the file at session start and writes to it continuously as it works. By session 3-5 the behavior shift is significant — the agent stops making mistakes you've already corrected and starts pre-empting issues before you catch them. Baby continual learning in a markdown file. ## Install **Claude Code** ```bash git clone https://github.com/blader/napkin.git ~/.claude/skills/napkin ``` **Codex** ```bash git clone https://github.com/blader/napkin.git ~/.codex/skills/napkin
