Conventions for writing or editing a SKILL.md skill package.

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

# Authoring a SKILL.md

Every skill is a self-contained package documented by its `SKILL.md`.

## Frontmatter

YAML frontmatter is required on every `SKILL.md`:

```yaml
---
name: kebab-case-skill-name        # matches the folder name
description: >                      # ≤ ~60 tokens — surfaced in manifests & routers
  One or two sentences on what the skill does and when to use it.
metadata:
  version: 1.0.0
  tags: [tag-one, tag-two]
---
```

The `description` is consumed by `cli/skills.json`, `registry.json`, and `.gemini/skills-index.json` — keep it tight (≤ ~60 tokens) and action-oriented. Generative skills open with a brief **Clarify-First** alignment step before producing output.

## Progressive disclosure

Keep the top of `SKILL.md` lean (Tier-1: purpose, when-to-use, the core workflow). Push depth into `references/` and load it on demand. Don't inline a 2,000-line knowledge base into the workflow.

## Structure

- `scripts/` — Python CLI tools, **standard library only, no ML/LLM calls** (see the python-tools rule).
- `references/` — expert knowledge bases the workflow links to.
- `assets/` — user-facing templates.

How to install

The exact contents, by fingerprint
mdr add borghei/claude-skills/.cursor/rules/skill-authoring.mdc@sha256:9c437bf617f8cdac

The line at the top of this page pins the label git:20260629.ee6fb37, 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.
