Skill Structure

Each skill follows the Agent Skills Open Standard:

• SKILL.md - Required skill manifest with frontmatter (name, description, metadata)
• references/ - (Optional) Reference files for detailed documentation

.well-known discovery

Each release uploads a dist/index.json alongside the skill tarballs. This index conforms to the agent-skills .well-known URI spec (schema v0.2.0) and is consumed by supabase.com to serve skills at https://supabase.com/.well-known/agent-skills/.

The release artifacts are built by scripts/build-release.ts and triggered by Release Please on every semver release.

Migrating to the official GitHub Action

jonathanhefner/agentskills-build-for-well-known is intended to be transferred to the agentskills org and published to the GitHub Marketplace. When that happens, scripts/build-release.ts and the pnpm build:release step in release-please.yml can be replaced with the Action directly:

- name: Build release artifacts
  uses: agentskills/build-for-well-known@v1   # replaces pnpm build:release
  with:
    skills-dir: skills
    output-dir: dist

Everything else — the Release Please trigger, the upload step, the supabase-plugin dispatch — stays exactly the same. The script and the Action produce identical output, so it is a drop-in swap.
