skill-doctor — Structural Audit for Claude Code Skills

Purpose

Single-pass structural audit of a Claude Code skill or workflow. Every check is a binary structural test (presence/absence, count, pattern match) — no semantic judgments. Same input produces same output on every run.

Grounded in:

• Claude Code Skills docs — official SKILL.md spec (name, description, allowed-tools, argument-hint, disable-model-invocation)
• Equipping agents with Agent Skills — 3-layer progressive disclosure architecture
• Agent Patterns — loop prevention
• Anthropic Engineering — Demystifying Evals
• Skill-creator technical rules (~/.claude/skills/skill-creator/references/technical-rules.md)
