Validate Skillmd

Q: What is a Claude Code skill and how does the Validate Skillmd skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Validate Skillmd is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.

Validate a SKILL.md file against the four-tier validation system: Tier 0 (locate), Tier 1 (standard or marketplace grading per the IS 100-point rubric), Tier 2 (static production gate — allowed-tools accuracy, auth protocol, dead code, tool safety, orchestration bounds), and Tier 3 (JRig 7-layer behavioral eval, opt-in via --thorough). Use when creating a new skill, checking skill quality, preparing for marketplace submission, running deep quality analysis, or gating a skill for production. Trigger with "validate this skill", "grade my skill", "deep eval", "check SKILL.md", "validate thorough", "/validate-skillmd".

Is Validate Skillmd safe to install?

A free static scan flagged 1 of ten categories (execution), including lower-severity patterns. Read the security scan below before installing — a pattern inside a code fence is weighted as an example, not an instruction.

Installing & verifying

Installing Validate Skillmd writes its SKILL.md to ~/.claude/skills/validate-skillmd/SKILL.md; Claude Code discovers it automatically on the next session — no restart flag needed. It declares no allowed-tools restriction, so it inherits your session’s existing tool access rather than narrowing it. To confirm it loaded, ask Claude to list its available skills — validate-skillmd should appear by name.

What Validate Skillmd needs to run

External services: The SKILL.md references pricing, quota, or rate limits — it likely calls a paid or rate-limited API. Check the source before wiring it into unattended automation.
Prerequisites: Ships its own installation / prerequisites section — it isn’t purely self-contained; read that first.
Worked code: 14 copy-paste code blocks in the body.
Depth: ~3,090 words, substantial — top of the catalog distribution.
