Use this skill when creating or refining Claude Code skill definitions. Skills are model-invoked capabilities that Claude activates autonomously based on context. Helps design focused skills with discovery-optimized descriptions, proper directory structures, and supporting resources. Automatically invoked when user requests "create a skill", "make a capability", "add autonomous behavior", or mentions skill development. Ensures skills follow Anthropic specifications with clear activation…
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 Dev Skill This skill helps create production-ready Claude Code skills following Anthropic's official specifications and best practices. ## Skills vs Agents: Key Differences | Aspect | Skills | Sub-agents | |--------|--------|------------| | **Invocation** | Model-invoked (automatic) | User-invoked (explicit) or Task tool | | **Scope** | Single capability | Multiple capabilities | | **File** | Directory with SKILL.md | Single .md file | | **Supporting files** | Can include templates, scripts | System prompt only | | **Discovery** | Description matching | Description + explicit invocation | | **Use case** | Reusable patterns, tools, workflows | Specialized AI assistants | **When to use Skills**: Create autonomous capabilities that Claude should invoke automatically when context matches (e.g., PDF processing, form filling, specific workflows) **When to use Agents**: Create specialized AI assistants for complex domains requiring multi-step reasoning (e.g., database expert, security auditor) ## Use Case Categories Anthropic identifies three common skill categories: | Category | Purpose | Example | |----------|---------|---------| …

How to install
mdr add andisab/swe-marketplace/skill-dev@sha256:8b1be5978a258178The line at the top of this page pins the label git:20260326.c644335, 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.
