Use when a durable lesson is needed after a bug fix, rollback, tool or workflow mistake, structural-analysis mismatch, or lost multi-agent context; resolve the lesson writer identity without initializing the whole project.
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
# Lessons Recording Record reusable prevention knowledge, not a task diary. A bug fix, rollback, incorrect tool judgment, workflow/mode mistake, failed validation, unsuitable task decomposition or lost multi-agent context warrants assessing whether a durable lesson exists. Do not create a lesson just to satisfy a ritual. Project rules and explicit deliverables remain binding. Default/lite may defer a nonessential lesson and continue unrelated safe work; strict leaves a required lesson incomplete until its identity, authority and evidence are available. No mode permits a guessed author, fabricated cause, anonymous placeholder or false saved claim. A request only to read lessons never creates identity or lesson files. ## One layered library Use the project's explicit compatible layout. Otherwise: - `docs/spec/lessons.md`: the single short entry, reading protocol, topic routing and high-frequency prevention summaries. - `docs/lessons/index.md`: searchable id/tags/read_when/summary/detail rows. - `docs/lessons/topics/<topic>.md`: complete records. - `docs/lessons/archive/YYYY-QN.md`: low-frequency history, read only when relevant. …

How to install
mdr add kunolu/640-skills/lessons-record@sha256:7ad4f5d22ba1684aThe line at the top of this page pins the label git:20260920.f9bbb90, 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.
