Validate and score Claude Code skill packages for quality, completeness, and best-practice compliance. Tests Python scripts, checks YAML frontmatter, and generates reports. Use when creating, validating, or auditing skill packages.
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 Tester Validate skill packages for structure compliance, test Python scripts for syntax and stdlib-only imports, and score quality across four dimensions (documentation, code quality, completeness, usability) with letter grades and improvement recommendations. Supports BASIC, STANDARD, and POWERFUL tier classification. ## Core Capabilities - **Structure validation** — check required files, directory layout, YAML frontmatter, and required SKILL.md sections against tier thresholds. - **Script testing** — AST syntax checks, stdlib-only import analysis, argparse and `__main__`-guard detection, runtime `--help` and sample-data execution. - **Quality scoring** — four equally weighted dimensions producing an overall score, letter grade (A+ through F), and a prioritized improvement roadmap. - **Tier classification** — BASIC / STANDARD / POWERFUL requirements for SKILL.md depth, script count/LOC, argparse, output formats, and error handling. - **Dual output** — human-readable reports and `--json` for CI/CD gating with meaningful exit codes. ## When to Use - Creating a new skill and validating it before publishing. - Auditing an existing skill's structure, scripts, and quality. …

How to install
mdr add borghei/claude-skills/skill-tester@sha256:9d98341f54fc78fcThe line at the top of this page pins the label v1.1.0, 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.
