Guide for creating Claude Code skills following Anthropic's official best practices. Use when user wants to create a new skill, build a skill, write SKILL.md, update an existing skill, or needs skill creation guidelines. Provides structure, frontmatter fields, naming conventions, and new features like dynamic context injection and subagent execution.
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
# Creating skills
Guide for creating Claude Code skills following Anthropic's official best practices.
## Quick start
```bash
# 1. Create skill directory
mkdir -p ~/.claude/skills/<skill-name>
# 2. Create SKILL.md with frontmatter
cat > ~/.claude/skills/<skill-name>/SKILL.md << 'EOF'
---
name: <skill-name>
description: <What it does>. Use when <trigger phrases>. <Key capabilities>.
---
# <Skill title>
<Instructions for the skill workflow>
EOF
# 3. Add optional resources as needed
mkdir -p ~/.claude/skills/<skill-name>/{scripts,references,assets}
```
## SKILL.md structure
### Frontmatter (YAML between `---` markers)
| Field | Required | Description |
|-------|----------|-------------|
| `name` | No | Display name. Defaults to directory name. Lowercase, hyphens, max 64 chars. |
| `description` | Recommended | What + when + capabilities. Max 1024 chars. Determines when Claude activates the skill. |
| `allowed-tools` | No | Tools Claude can use without asking permission when skill is active. |
| `argument-hint` | No | Autocomplete hint for arguments. Example: `[issue-number]` |
| `disable-model-invocation` | No | `true` to prevent auto-invocation (manual `/name` only). |

How to install
mdr add fvadicamo/dev-agent-skills/creating-skills@sha256:ba4f7f6dc8cb8023The line at the top of this page pins the label git:20260517.91f300b, 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.
