Learn

Extract learnings from the current conversation and add them to the project's CLAUDE.md.

Steps

1. Review current conversation for friction moments:

   • Commands/approaches that failed before finding the right way
   • Non-obvious solutions or workarounds discovered
   • If nothing notable was learned: report "No new learnings to capture." and STOP.

2. Resolve project CLAUDE.md:

   • If active session exists: read Working Dir from _overview.md, use [Working Dir]/CLAUDE.md
   • Otherwise: use git rev-parse --show-toplevel to find repo root, use [repo root]/CLAUDE.md
   • If CLAUDE.md doesn't exist: create it

3. Append learnings:

   • Find or create ## Learnings section in CLAUDE.md
   • Add one line per learning, format: - When [situation], [do this / don't do that]
   • Generalize as much as possible. Never reference specific files, variables, or code locations. Extract only generic techniques, rules, and patterns that apply broadly across projects and sessions.
   • Keep it terse — one line, no paragraphs
   • Don't duplicate entries already present

4. Commit:

   • cd [repo root] && git add CLAUDE.md && git commit -m "docs: add learnings"

5. Report:

   • List the learnings added
   • Or: "No new learnings to capture."
