Guides creation, audit, and improvement of portable Agent Skills using the shared.
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
# AI Skill Builder <purpose> Build Agent Skills using the shared `SKILL.md` format and Anthropic's methodology: the smallest portable core that works in every named target, plus explicit runtime adapters. Portability is a tested compatibility claim, not a formatting style. `references/sources.md` cites host documentation for Claude Code, Codex, and Qwen Code; every other host is untested here, so verify the one you target (Step 1). This methodology deliberately requires consistent semantic XML regions inside the Markdown body. That is a quality policy for reducing ambiguity in complex operational instructions, supported by current Anthropic prompting guidance and checked by the forward tests in Step 4. It is not a parser requirement of the portable Agent Skills specification, an authorization boundary, or a claim that XML alone prevents prompt injection. **Primary methodology source**: "The Complete Guide to Building Skills for Claude" (Anthropic, January 2026) - PDF: https://resources.anthropic.com/hubfs/The-Complete-Guide-to-Building-Skill-for-Claude.pdf - Extracted text: `references/ai-skill-builder-guide.md` **Portable format source**: https://agentskills.io/specification …

How to install
mdr add ahundt/autorun/ai-skill-builder@sha256:43f5ebab386190e8The line at the top of this page pins the label v1.3.0, 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.
