Your library of skills made by source-to-skill - lists every video, course, podcast, paper, book, article, docs and repo skill installed for Claude Code, Codex, Copilot, Gemini and other agents, finds which one covers a question, flags skills whose playlist, channel, feed or docs has moved on, and refreshes them. Use when the user runs /skill-library, or asks "what skills do I have", "which of my skills covers X", "what did I learn about X", "are any of my skills out of date…
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
# skill-library
Run from this skill's directory:
python3 scripts/library.py
It prints JSON: every skill folder with a `source.json` (or, for topic
skills, `sources/*.source.json`) under the agents' user and project skills
folders, with its description, sources, age, and `refresh_due`. It reads
only; pass `--root <dir>` for another folder and `--stale-days N` to change
the 30-day refresh threshold.
## List
Show a compact table: name, type, title, extracted (date), tokens, and a
mark on `refresh_due` skills. Group by source type when there are more than
ten. No skills found → say where you looked and suggest
`/source-to-skill <url-or-file>`.
## Find
For "which skill covers X": match X against each skill's description first,
then open only the matching skills' `SKILL.md` indexes. Answer with the
skill name, the support file, and the deep link or section where X is
covered, then answer the question itself from that file. Name every skill
that covers X when several do; when they disagree, show both positions
side by side.
## Refresh
`refresh_due` marks playlists, channels, podcast feeds, docs sites, repos,
…Read the whole file at its exact version.
How to install
mdr add michalstrnadel/source-to-skill/skill-library@sha256:3cc7a238105c1be3The line at the top of this page pins the label git:20261026.e43070c, 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.
