Guide for creating, structuring, and improving Claude skills (SKILL.md). Use when building a new skill, reviewing an existing skill, writing SKILL.md frontmatter, defining trigger conditions, troubleshooting skill problems (not triggering, over-triggering, instructions not followed), or planning skill distribution. When working on any skill in this repository: also load the cc-best-practices skill, and always update both CLAUDE.md and README.md skill tables after any skill change. Do NOT use…
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.

# Skill Best Practices
Reference: https://resources.anthropic.com/hubfs/The-Complete-Guide-to-Building-Skill-for-Claude.pdf
## Instructions
### Step 1: Identify your use case category
Determine which type of skill you're building:
- **Document & Asset Creation** — consistent output (docs, designs, code)
- **Workflow Automation** — multi-step processes with consistent methodology
- **MCP Enhancement** — workflow guidance on top of MCP tool access
Define 2–3 concrete use cases before writing anything (see Planning section below).
### Step 2: Create the folder and SKILL.md
- Name the folder in kebab-case (e.g. `my-skill-name`)
- Create exactly `SKILL.md` (case-sensitive) inside it
- Write YAML frontmatter with `name` and `description` (see Technical requirements)
### Step 3: Write the description — this is the most critical part
The description controls when Claude loads your skill. It must include:
- **WHAT** the skill does
- **WHEN** to use it (specific trigger phrases)
- Optional: negative triggers ("Do NOT use for...")
See "Writing effective descriptions" for good/bad examples.
### Step 4: Write the body instructions
…Read the whole file at its exact version.
How to install
mdr add aiskillstore/marketplace/skill-best-practices@sha256:a724766d42f2d5afThe line at the top of this page pins the label git:20260926.62148e4, 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.
