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:

1. scripts/skill_validator.py — structure + documentation compliance
2. scripts/script_tester.py — Python script syntax/imports/runtime/output testing
3. scripts/quality_scorer.py — multi-dimensional scoring with letter grade
4. scripts/security_scorer.py — security posture scoring (also available via quality_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)
