2,658 skills, deduplicated and indexed across 15 domains — one machine-readable catalog for Claude, Codex, Cursor, Antigravity, and anything that loads SKILL.md.
One catalog, every runtime — no lock-in.
Overlapping skills collapse into one canonical copy per id, by a strict priority rule.
Every skill is sorted into one of 15 normalized domains, so browsing 2,658 stays effortless.
A single skills_index.json exposes id, version, domain, trigger, path.
A static catalog — no pip, no install graph. Point your runtime at skills/.
Contributions are validated against the manifest and linted for structure, reported on the PR.
Works with any agent that loads SKILL.md skills — no vendor coupling.
