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.
• Embedding a quality gate into a CI/CD pipeline.
