Creates, refines, and validates Agent Skills following the open standard at agentskills.io, Claude Code extensions, and Anthropic best practices. Use when building, creating, generating, or designing new skills.
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 Builder
## Purpose
Creates production-ready Agent Skills following the official specifications
and best practices.
## When I Activate
I automatically load when you mention:
- "build a skill" or "create a skill"
- "generate a skill" or "make a skill"
- "design a skill" or "new skill"
## Authoritative References (Read These First)
Before creating any skill, read the current versions of these docs:
1. **Agent Skills Specification** (the open standard):
https://agentskills.io/specification
2. **Skill Authoring Best Practices** (Anthropic):
https://platform.claude.com/docs/en/agents-and-tools/agent-skills/best-practices
3. **Claude Code Skills Documentation** (Claude Code extensions):
https://docs.claude.com/en/docs/claude-code/skills
4. **Example Skills** (reference implementations):
https://github.com/anthropics/skills
These are the source of truth. If anything in this skill contradicts those
docs, the official docs win.
## What I Do
Create skills in 5 steps:
1. **Clarify** → Define purpose, scope, activation keywords
2. **Design** → Plan structure, decide on progressive disclosure
3. **Generate** → Create SKILL.md with proper frontmatter and body

The line at the top of this page pins the label v2.0, 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.
