Ten gates between a skill and the catalog.

The gate is why the catalog is small. A skill is listed only when all ten of these hold, and the checks are graded from generated artifacts, not from the author’s word.

  1. The upload zip is under 50 MB and places SKILL.md at its root.
  2. SKILL.md carries valid frontmatter with a name and a description.
  3. Every relative link resolves inside the bundle.
  4. The bundle contains no private paths, secrets, internal product details, proprietary prompts, or one harness’s commands presented as universal.
  5. The skill states required capabilities, optional paid routes, fallback behavior, support boundaries, and commercial-use caveats.
  6. At least three representative prompts have been run with and without the skill.
  7. Assertions are graded from generated artifacts, not self-reported by the author.
  8. Included scripts pass syntax checks and, where applicable, at least one observable smoke scenario.
  9. The listing copy makes no unsupported performance, revenue, compatibility, or customer claims.
  10. Version, license, installation, and support documents match the shipped bundle.
