hard-won-skill-extractor skillA
hard-won-skill-extractor is agent-read markdown (skill) from yeaight7/agent-powerups: 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..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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@git:20260606.a1fabe5mdr add yeaight7/agent-powerups/hard-won-skill-extractor@sha256:f99e30a12bb133eaPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
