Extract a reusable pattern from this session and route it to where something reads it, or drop it. Use when saving what was learned in this session (今回の学びを残して).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /learn-eval - Extract, Evaluate, then Save
Extract a reusable pattern from the session, gate it, and route every Save to a destination something actually reaches.
## What to Extract
Look for:
1. **Error Resolution Patterns** — root cause + fix + reusability
2. **Debugging Techniques** — non-obvious steps, tool combinations
3. **Workarounds** — library quirks, API limitations, version-specific fixes
4. **Project-Specific Patterns** — conventions, architecture decisions, integration patterns
## Process
1. Review the session for extractable patterns
2. Identify the most valuable/reusable insight
3. **Determine the destination — there is no parking lot.**
Every Save must land somewhere that something actually routes to (ADR-0047), so pick
one of exactly two:
- **Absorb into an existing asset** — the pattern belongs inside a skill, rule, or
`hooks/README.md` section that already owns the topic. Name the file and the section.
This is the default: an addition to a reachable asset beats a new file. A skill's value
lies in its comprehensiveness, so appending improves it — "I don't want to pollute the

How to install
mdr add shimo4228/claude-harness/learn-eval@sha256:6920b7f764be0a81The line at the top of this page pins the label git:20261010.b5821aa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
