Turn session corrections and approved decisions into minimal edits to checks, skills, AGENTS.md, or decision logs.
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
# Lesson Learned Turn what a session taught into the smallest durable change in the right owner, so projects align bit by bit without piling up rules. Run it on `/lesson-learned` or "lessons learned", and propose it as a `(Lesson Learned)` suggestion after an implementation, approved decisions, a correction, or a repeated instruction. [skillify](../skillify/SKILL.md) owns creating and extending skills, [trim](../trim/SKILL.md) owns shortening, and [AGENTS.md guidance](../repository-docs/references/agents.md) defines what each instruction layer holds. ## Workflow 1. **Collect candidates**: list the user's corrections, approved decisions with their reason, repeated instructions, workarounds, and rules that proved stale, wrong, or ignored, each with where it came from. Drop session-specific paths, one-off values, and secrets. Done when every correction and approved decision is listed or excluded with a reason. …

How to install
mdr add fmind/dot/lesson-learned@sha256:01c493049ec6ea1eThe line at the top of this page pins the label git:20261104.b85f7c2, 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.
