Validate SKILL.md

Grade any SKILL.md file against the Intent Solutions rubric (validator v7.0 / schema 3.3.1). Four-tier validation: Tier 0 (locate), Tier 1 (standard or marketplace grading), Tier 2 (static production gate), Tier 3 (JRig behavioral eval — opt-in).

Source of truth: /skill-creator validation workflow + claude-code-plugins-plus-skills/000-docs/SCHEMA_CHANGELOG.md + j-rig-skill-binary-eval/ (Tier 3).

Overview

Schema 3.3.1 enforces the 8-field IS enterprise required-field set at marketplace tier (name, description, allowed-tools, version, author, license, compatibility, tags). Anthropic's spec floor (name + description only) sits underneath; the IS rubric sits on top. Modes:

• Standard (default): Mirrors platform.claude.com/docs/en/agents-and-tools/agent-skills/overview exactly. Required: name, description. Everything else is silent unless invalid type/value. Fast (~10 sec).
• Marketplace (--marketplace): 8-field enterprise required set + 100-point IS rubric. Missing required fields = ERROR, not warning. The --enterprise flag is a deprecated alias. Fast (~10 sec).
• Deep (--deep): Intent Solutions Deep Evaluation Engine — 10 weighted dimensions, trust badges, Elo competitive ranking, optional LLM quality assessment via Groq. Fast (~30 sec).
• Thorough (--thorough): Adds Tier 3 JRig behavioral eval on top of Tier 1+2. Runs 7-layer eval across Haiku/Sonnet/Opus. Slow (~10–30 min) and costs ~$2–5 per skill in API spend — opt-in only. Right for production-gating, not iterative authoring.

Performance + cost note: Tiers 0–2 run in seconds and are free. Tier 3 (JRig) is opt-in because behavioral eval across the model matrix is genuinely expensive. Default invocations stay fast; --thorough is for the moment a skill is being promoted to production or marketplace-verified.
