Skills registry
The leaderboard is public. So are the evals.
Skills ranked by measured lift — not download counts. Every score is backed by evals you can inspect, case by case.

SkillScore
One number, four signals — and one of them can't be bought.
Benchmark lift at 32% (pass rate with the skill minus without), live pass rate from real runs at 32%, an AI-judged quality review at 16%, and adoption at 20% — which grows logarithmically and is capped by org diversity, so volume from a single workspace can’t buy a rank. A missing signal isn’t scored as zero; the remaining weights rescale.

SkillSafety
Nothing lists without clearing the gate.
Every submission runs a three-stage pipeline — static scan, AI security review, content check — and carries its band. Blocked skills never appear.

Skill router
Know which skills your agent actually uses.
smart_route() ranks a shortlist, then compares what you offered against what the agent activated. Under 40% flags menu bloat — and shows which skills to cut.

Build on it
Your team’s skills, not just everyone else’s.
Fork a public skill or write your own, prove it works on your cases, and ship it to your team — on the same rails that rank the public registry. Authoring, evals, versioning, access: skills governance without building the system.

From your draft to your team’s router
01Author or forkStart from a benchmarked skill or a blank one. The skill format, linter, and local safety scan are built in.
02Eval before you shipRun the same harness that scores public skills against your own cases — pass rate before and after, and the exact lift.
03Share with your teamPublish to your workspace. Your agents pick it up via smart_route() — and real usage feeds back into the score.
04Governed by defaultThe same safety gate and pinned versions as the public registry. Governance runs on the rails — not as a process you police.
Skills governance
Everything you’d build internally — already here.
Keeping a team’s skills authored, evaluated, safe, versioned, and shared is real work — skills governance. In-house it’s a stack you build and maintain. Here, it’s what the registry already does.
