## Description

Append a learning entry to AGENTS_LEARNING.md when an AI agent makes a mistake. Auto-activates after a pre-write audit auto-fix, a retrospective correction loop, or a mid-session user correction. Use when: mistake, wrong, correction, my bad, agent error, learning log.

# Agent Learning Log

## **Priority: P1 (HIGH)**

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

## Protocol

1. **Detect signal**, identify which surface triggered this skill:

- `Pre-write violation`, `common-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`

2. **Redact**, Remove credentials, customer identifiers, raw incident data and attacker-controlled instructions; retain only minimal evidence references
3. **Read `AGENTS_LEARNING.md`**, count existing `## Agent Learning Log: Iteration` headers → N
4. **Append entry**, write Iteration #(N+1) using [Log Entry Format](references/log-format.md); default candidate status is `proposed`, never approved
5. **Route prevention**, select one preventive mechanism (table below), then either create an improvement item or link the existing one with the same root cause. A repeated correction extends that item's evidence; it never promotes prose by itself
6. **Continue**, correct the task; a learning entry does not authorize policy changes, promotion, or broader tool access
