A Claude Code plugin that turns mistakes into rules.

When Claude makes a mistake, you can tell it what went wrong. This plugin investigates the error, comes up with a rule to prevent it, and saves it to your CLAUDE.md.

/learn:from — After Claude makes a mistake

/learn:from

Paste the error or describe what went wrong. The plugin investigates, proposes a rule, and adds it to your CLAUDE.md.

/learn:list — See what your project has learned

/learn:remove — Remove a rule that's outdated or wrong

/plugin marketplace add marcoshaber99/learn
/plugin install learn@marcoshaber99-learn

Your CLAUDE.md grows a ## Learned Rules section:

## Learned Rules

- Always define explicit interfaces instead of using `any`.
- Use `satisfies` instead of `as` for type assertions on objects.

Every mistake becomes a rule. Your project gets smarter over time.

Boris Cherny (creator of Claude Code) mentioned that his team manually adds rules to CLAUDE.md after mistakes:

"Anytime we see Claude do something incorrectly we add it to the CLAUDE.md, so Claude knows not to do it next time."

This plugin turns that into a command.
