Use when a tricky bug, non-obvious workaround, hidden gotcha, or undocumented behavior took real debugging effort to discover and should be captured as a reusable learned skill.
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
# Hard-Won Skill Extractor This skill serves to document how to manually extract a useful learned skill into a reusable markdown file. ## Core Principle Reusable skills are not code snippets to copy-paste, but **principles and decision-making heuristics** that teach an agent HOW TO THINK about a class of problems. **The difference:** - BAD (mimicking): "When you see ConnectionResetError, add this try/except block" - GOOD (reusable skill): "In async network code, any I/O operation can fail independently due to client/server lifecycle mismatches. The principle: wrap each I/O operation separately, because failure between operations is the common case, not the exception." ## Quality Gate Before extracting a skill manually, ALL three must be true: - "Could someone Google this in 5 minutes?" → NO - "Is this specific to THIS codebase?" → YES - "Did this take real debugging effort to discover?" → YES ## Recognition Signals Extract ONLY after: - Solving a tricky bug that required deep investigation - Discovering a non-obvious workaround specific to this codebase - Finding a hidden gotcha that wastes time when forgotten - Uncovering undocumented behavior that affects this project …

How to install
mdr add yeaight7/agent-powerups/hard-won-skill-extractor@sha256:f99e30a12bb133eaThe line at the top of this page pins the label git:20260606.a937127, 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.
