Lint a Summer skill before commit, audit the whole library, or check a behavioral spec assertion — static structural rules plus behavioral specs.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# /skill-test — Validate a Summer Skill

Three modes. Pick by the user's intent.

## Mode: `static` — Structural lint (default for "test this skill")

For a single skill at `library/skills/<slug>/`, run these checks:

1. **Frontmatter completeness.** `name`, `description`, `license`, `compatibility`, `category` present. `name` matches the directory name.
2. **SKILL.md length.** ≤ 500 lines (progressive disclosure: push detail into references).
3. **MCP-preferred + file-edit-fallback.** If the skill mutates scenes or resources, body must show both:
   - At least one `summer_*` MCP tool example.
   - At least one file-edit fallback block (e.g., raw `.tscn` snippet) OR an explicit "no fallback for this — Summer MCP required" note.
4. **Collaborative protocol.** If the skill triggers user-visible writes, body must contain at least one of: `May I`, `I'm about to`, `Continue?`, `OK?`, `Proceed?`. Skills that only inspect/read are exempt.
5. **Template-id resolved.** If the skill's frontmatter declares `template-id: <id>`, that id must exist in the template registry: `library/templates/<id>/resource.yaml` (see `library/templates/README.md`).

How to install

The exact contents, by fingerprint

mdr add summerengine/summer/skill-test@sha256:4bf29fb48f492ede

The line at the top of this page pins the label git:20261016.e9d6e70, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
