Token cost is the o200k count of the tools list JSON, including schemas, before any tool is called.

• validate_skill

  Fully validate a Claude SKILL.md file — frontmatter rules, body quality, security scan, tool collision check. Returns score (0–100), gate (pass/review/fail), and structured errors/warnings.

• lint_frontmatter

  Parse and validate only the YAML frontmatter of a Claude Skill. Returns parsed fields and any rule violations. Use during iterative authoring.

• scan_security

  Scan a Claude Skill for dangerous shell commands, hardcoded secrets, or prompt-injection phrases. Returns findings with excerpts.

• score_skill

  Run full validation and return a 0–100 score plus a ship gate (pass/review/fail). Minimal payload suitable for CI/CD pipelines.
