Skill Tester
This is a testing utility for validating Claude Code skills before deployment. You'd use it when building or debugging skills to make sure they work as expected without pushing to production first. The description is minimal, but the core value is straightforward: catch issues early in your skill development workflow. It's the kind of meta-tool that's easy to overlook until you've been burned by a broken skill in the wild, at which point you'll wonder why you weren't using something like this from the start.

Skill Tester
Tier: POWERFUL · Category: Engineering Quality Assurance · Dependencies: None (Python stdlib only)
Meta-skill that validates, tests, and scores skills in this repository. Four tools, run from the repo root with full paths:
scripts/skill_validator.py— structure + documentation compliancescripts/script_tester.py— Python script syntax/imports/runtime/output testingscripts/quality_scorer.py— multi-dimensional scoring with letter gradescripts/security_scorer.py— security posture scoring (also available viaquality_scorer.py --include-security)
Scope note: this skill's tier line-count minimums measure legacy skills. For authoring new skills,
engineering/write-a-skill(SKILL.md under ~100 lines, Matt Pocock doctrine) is the binding standard — do not pad a new skill to satisfy a tier minimum here.
Quick Start (exact, runnable from repo root)
# 1. Validate structure (exit non-zero on failure — usable as a gate)
