Details
From the project READMELearn Rule
Capture a lesson from the current session into permanent memory.
Trigger
Use when the user says "remember this", "add to rules", "don't do that again", or after a mistake is identified.
Workflow
- Identify the lesson — what mistake was made? What should happen instead?
- Format the rule with full context.
- Propose the addition and wait for user approval.
- After approval, persist to LEARNED section or project memory.
Format
[LEARN] Category: One-line rule
Mistake: What went wrong
Correction: How it was fixed
Wiki-scoped rules
Append Wiki: <slug> to bind the rule to a single pro-workflow wiki. The rule loads only when that wiki is in scope, avoiding cross-project pollution:
[LEARN] Editing: Cite a sources.md row before adding any wiki claim.
Wiki: agent-memory
The capture hook auto-detects Wiki: <slug> and links the learning to that wiki via learnings_wiki.
Categories
| Category | Examples |
|---|---|
| Navigation | File paths, finding code, wrong file edited |
| Editing | Code changes, patterns, wrong approach |
| Testing | Test approaches, coverage gaps, flaky tests |
| Git | Commits, branches, merge issues |
| Quality | Lint, types, style violations |
| Context | When to clarify, missing requirements |
| Architecture | Design decisions, wrong abstractions |
| Performance | Optimization, O(n^2) loops, memory |
Example
Recent mistake: Edited wrong utils.ts file
[LEARN] Navigation: Confirm full path when multiple files share a name.
Add to LEARNED section? (y/n)
Guardrails
- Always wait for user approval before persisting.
- Keep rules to one line — specific and actionable.
- Bad: "Write good code". Good: "Always use snake_case for database columns".
- Include the mistake context so the rule makes sense later.
Output
- The proposed
[LEARN]rule with category - Confirmation after persisting
