Scan skills for prerequisite tools, MCP servers, and auth requirements, then check if everything is installed and authenticated. Offers to fix issues. Use when setting up a new machine, after installing skills, or to verify your environment. Triggers: "check prerequisites", "skill prereqs", "are my tools installed", "verify skill dependencies", "/claude-skill-prereq-audit".
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 Prerequisite Check Scan installed skills, discover their tool/MCP/auth dependencies via heuristic parsing, check if everything is installed and authenticated, and offer to fix issues interactively. ## When to Use - Setting up a new machine - After installing new skills - Verifying environment is ready for all skills - Debugging "tool not found" errors during skill execution ## Arguments Parse from the user's invocation: - **Skill names**: Any tokens after the command → filter to those skills only - **Default**: scan all skills in `~/.claude/skills/` and `.claude/skills/` ## Workflow ### Phase 1: Discover Skills 1. Glob for `~/.claude/skills/*/SKILL.md` and `.claude/skills/*/SKILL.md` 2. Follow symlinks 3. If user specified skill names, filter the list to matching directory names 4. Exclude this skill (`skill-prereq-check`) from the scan list — its own SKILL.md contains tool references as parsing examples, not actual dependencies 5. Read each SKILL.md file ### Phase 2: Parse Prerequisites For each SKILL.md, extract dependencies using these heuristics: **CLI tools:** …

How to install
mdr add jackchuka/skills/claude-skill-prereq-audit@sha256:c8f240e90a738d36The line at the top of this page pins the label git:20260604.0da3398, 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.
