lesson

Store a lesson learned from the current conversation. Triggered by /lesson command. Use when Master signals that the recent conversation contains a pitfall, fix, or key insight that should be persisted to long-term memory.

Lesson Extraction & Storage

When triggered, extract and store lessons from the recent conversation context.

Steps

Scan recent context — identify the pitfall, bug fix, or key insight just discussed

Store technical layer (category: fact, importance ≥ 0.8):

Pitfall: [symptom]. Cause: [root cause]. Fix: [solution]. Prevention: [how to avoid].

Store principle layer (category: decision, importance ≥ 0.85):

Decision principle ([tag]): [behavioral rule]. Trigger: [when]. Action: [what to do].

Verify —
```
memory_recall
```
with anchor keywords to confirm both entries retrievable
Report — tell Master what was stored (brief summary)

Rules

Keep entries short and atomic (< 500 chars each)
If the lesson also affects a checklist or SKILL.md, update those files too
If no clear lesson is found in recent context, ask Master what to store
