Capture Elixir/Ecto/LiveView lessons and Hex API rules. Use after corrections.
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 From Fix After fixing a bug or receiving a correction, capture the lesson to prevent future mistakes. ## Usage ``` phx-learn-from-fix Fixed N+1 query in user listing - was missing preload phx-learn-from-fix String vs atom key mismatch in params handling phx-learn-from-fix LiveView assign_async needs render_async in tests phx-learn-from-fix --library ical --scope personal ICal.to_ics output needs CRLF line endings phx-learn-from-fix --library ical --scope project Use method: "PUBLISH" for calendar feeds ``` ## Workflow ### Step 1: Verify the Lesson Persist only one of: - A completed fix verified by tests, reproduction, or user confirmation - An explicit rule the user taught or asked to save Stop without writing if neither condition is met. Do not save a hypothesis, unverified workaround, investigation narrative, or unsolved error. Use `phx-compound` for a detailed completed investigation. Capture the root cause as a concise actionable rule, not the symptom. ### Step 2: Select the Route When both `--library <package>` and `--scope personal|project` are present, use the [Library Route](#library-route). Require both flags; do not guess scope. …

How to install
mdr add oliver-kriska/claude-elixir-phoenix/phx-learn-from-fix@sha256:76fa56735c838aaaThe line at the top of this page pins the label git:20260929.c08ad14, 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.
