Federated skill index
LoopSkill's own catalog is curated and quality-gated. Alongside it, our federation crawl indexes agent skills published across a set of external community and vendor registries — searchable inside LoopSkill (try the unified search), but each one still lives, is licensed, and is maintained at its own origin. We link to that origin, never rehost it.
102,534 externally indexed skills across 31 upstream sources (live count, this build — self-updates client-side without a rebuild).

Missing a registry? Propose one
Know a public repo or registry of agent skills LoopSkill doesn't index yet? Propose it — we pre-flight the repo (does it exist, how many SKILL.md files, what license) and open a review issue. Accepted sources become searchable in the federated index.
Agent or no-JS? Call the API directly
curl -X POST https://app.loopskill.io/api/federation/propose \
-H "Content-Type: application/json" \
-d '{"repo_url":"https://github.com/owner/repo"}'Or from a connected agent: the loopskill_propose_registry MCP tool. Proposals are deduped per 24h per (identity, repo).
How this index works
Each source page lists a representative sample of entries with a link to the skill's origin (its real hosting repository or registry page) — never a copy of its content. Counts are read live from LoopSkill's federation API at build time; if a source is briefly unreachable, its row and page are simply omitted from that build rather than showing a stale or invented number.
