Agent Learning Log

Priority: P1 (HIGH)

Write structured mistake entry to AGENTS_LEARNING.md in project root before retrying any corrected action.

Protocol

  • Detect signal — identify which surface triggered this skill:
  • Pre-write violationcommon-feedback-reporter violation block emitted with Auto-fixed: YES
  • User correction — user used correction language mid-session
  • Session retrospective — correction loop found during common-session-retrospective
  • Read AGENTS_LEARNING.md — count existing ## Agent Learning Log: Iteration headers → N
  • Append entry — write Iteration #(N+1) using format in Log Entry Format
  • Continue — proceed with corrected action (non-blocking)

Guidelines

  • One entry per correction event — not one per file or per task
  • Concrete mistakes only — name specific file, rule, or action that wrong
  • "Better Approach" must actionable — state what to , not what to avoid
  • Create file if missing — bootstrap with header from Log Entry Format
  • Never skip for "minor" corrections — all corrections learning signals

Anti-Patterns

  • No vague mistakes: "I made a mistake" → name specific pattern or rule violated
  • No skipping log: Even if already in hurry to fix, append entry first (it takes <10 seconds)
  • No duplicate entries: One correction event = one entry, even if multiple files affected
  • No overwriting: Always append to bottom; never edit past entries

References

  • Log Entry Format — full entry template + AGENTS_LEARNING.md bootstrap

How to use it

Copy the folder

Take hoangnguyen0403/common-learning-log from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
