Validate all skills in skills/ against the agentskills.io spec and Claude Code best practices.
For each skill directory, verify:
| Check | Rule |
|---|---|
name format | 1-64 chars, lowercase alphanumeric + hyphens, no leading/trailing/consecutive hyphens |
name matches directory | Directory name must equal name field |
description length | 1-1024 characters, non-empty |
| Optional fields valid | license, metadata, compatibility if present |
| Check | Rule |
|---|---|
| Description format | Third person, describes what + when to use |
| Body length | Under 500 lines |
| Loading is one-level deep | SKILL.md is the only progressive-disclosure entry point: every reference file must be reachable from SKILL.md. References may cross-link each other for navigation (see note below). |
| Links are markdown | Use [text](path) not bare filenames |
| No redundancy | Don't repeat description in body |
| Concise | Only add context Claude doesn't already have |
One-level-deep vs. cross-linking. The one-level-deep rule targets progressive-disclosure loading chains — a reference that can only be discovered by loading another reference first (
SKILL.md→a.md→b.md, whereb.mdis not linked fromSKILL.md). That is a defect: it hides content from the loader.It does not forbid navigational cross-links. Per AGENTS.md, reference files end with a "Related Skills" footer linking sibling references, and this is required. A cross-link is fine as long as both endpoints are also reachable directly from
SKILL.md. Only flag a reference that is reachable exclusively through another reference.
Find all skill directories:
fd -t d -d 1 . skills/
For each skill, read SKILL.md and check against the rules above
