# skill-lint Validate [Agent Skills](https://agentskills.io) (`SKILL.md`) for Claude.ai, Claude Code, and other agents. Catches errors **before** uploading to Claude.ai Web — name format, description length, angle brackets, disallowed frontmatter fields, and more. ## Usage ### GitHub Action ```yaml # .github/workflows/skill-lint.yml name: Skill Lint on: [push, pull_request] jobs: lint: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - uses: himself65/skill-lint@v3 with: path: 'skills' # directory containing skill folders (default: '.') claude: 'false' # set to 'true' to enable Claude.ai-specific checks claude-code: 'false' # set to 'true' to allow Claude Code frontmatter extensions marketplace: 'true' # check .claude-plugin/marketplace.json (default: 'true') ``` ### CLI ```bash npx skill-lint ./skills ``` Or install globally: ```bash npm install -g skill-lint skill-lint ./skills ``` ### Options | Flag | Description | |------|-------------| | `--json` | Output results as JSON | | `--quiet`, `-q` | Only show errors (suppress warnings) | | `--claude` | Enable Claude.ai-specific checks (reserved-word names, angle brackets in description) | | `--claude-code` | Accept Claude Code frontmatter extensions (`context`, `model`, `paths`, …) instead of reporting them | | `--no-marketplace` | Skip the plugin marketplace check (auto-detected, so already a no-op when no manifest exists) | ## What it checks | Rule | Severity | Description | |------|----------|-------------| | Missing `SKILL.md` | error | Skill directory must contain a `SKILL.md` file | | `SKILL.md` filename casing | warning | A `skill.md` (or other casing) is read, but clients matching the name exactly will not find it | | Invalid frontmatter | error | Must start with `---`, valid YAML mapping, closed with `---` | | Missing `name` | error | Required field | | Name format | error | 1-64 chars, lowercase letters (including non-ASCII), digits and hyphens, no leading/trailing/consecutive hyphens | | Name/directory mismatch | error | `name` field must match parent directory name (compared Unicode-normalized) | | Duplicate name | warning | Two skills in the same namespace declare the same `name`; skills in different plugins are namespaced and exempt | | Missing `description` | error | Required field | | Description length | error | Must be 1-1024 characters | | `compatibility` length | error | If present, must be 1-500 characters | | `allowed-tools` format | warning | Must be space-separated with balanced parentheses; a comma-separated list is flagged | | `metadata` format | warning | Must be a mapping of string keys to string values | | Unknown fields | error | Only `name`, `description`, `license`, `allowed-tools`, `metadata`, `compatibility` allowed | | Claude Code extension fields | error | Frontmatter fields Claude Code adds to the spec; suppressed by `--claude-code` | | Empty body | warning | `SKILL.md` has no instructions after the frontmatter | | Body line count | warning | `SKILL.md` body should stay under 500 lines (spec recommendation) | | Body token estimate | warning | `SKILL.md` body should stay under ~5000 tokens (spec recommendation) | | Reference depth | warning | Relative file references should be at most one directory level deep | | Missing reference | warning | File references in the body must exist on disk — Markdown links, plus plain-text paths such as `scripts/extract.py` when the skill has that directory | | Unreferenced reference file | warning | A file in `references/` that neither `SKILL.md` nor another reference file mentions never loads | ### Claude.ai-specific checks (opt-in) Pass `--claude` (CLI) or set `claude: 'true'` (Action) to enable extra checks specific to Claude.ai web uploads. These are **not part of the agentskills.io spec**: | Rule | Severity | Description | |------|----------|-------------| | Reserved words | error | Name cannot contain `anthropic` or `claude` | | Angle brackets | error | Description cannot contain `<` or `>` | ### Claude Code frontmatter extensions (opt-out) Claude Code accepts frontmatter fields the spec does not define — `when_to_use`, `argument-hint`, `arguments`, `disable-model-invocation`, `user-invocable`, `disallowed-tools`, `model`, `effort`, `context`, `agent`, `background`, `hooks`, `paths`, and `shell`. They load fine in Claude Code, but claude.ai uploads and the Skills API reject them, so they are reported as errors with a message naming the tradeoff rather than lumped in with typos. Pass `--claude-code` (CLI) or set `claude-code: 'true'` (Action) when Claude Code is the only target. Fields outside both lists still error, and the field values themselves are not validated. ### Plugin marketplace checks (automatic) If a `.claude-plugin/marketplace.json` exists at or above the scan root, its version fields are checked against the `plugin.json` of every plugin it points at. The search stops at the repository root (a directory containing `.git`), so it never picks up a manifest from a parent checkout. Repositories without a manifest are unaffected — no diagnostics, no output change. This is an **internal-consistency** check, not a spec-conformance one. The two files are edited by different tools at different times, and nothing else catches the drift: release archives typically package only the skill directories, so a stale marketplace manifest ships the wrong version to anyone running `npx plugins add` while every check stays green. | Rule | Severity | Description | |------|----------|-------------| | Invalid marketplace JSON | error | `marketplace.json` must parse and be a JSON object | | Missing `plugins` | error | `marketplace.json` must contain a `plugins` array | | Missing `source` | error | Each `plugins[]` entry needs a `source` | | Unresolvable `source` | error | A local `source` must contain a readable `plugin.json` (non-local sources are skipped) | | Plugin version drift | error | `plugins[].version` must equal that plugin's `plugin.json` version | | Metadata version drift | error | `metadata.version`, when present, must equal the highest plugin version | Versions are only compared when at least one side declares one, so a manifest that omits versions entirely is left alone. ## Programmatic API ```typescript import { lintSkills, lintSkill } from 'skill-lint'; const result = await lintSkills('./skills', { claude: false }); console.log(result.errorCount); // number of errors console.log(result.warningCount); // number of warnings for (const skill of result.skills) { for (const d of skill.diagnostics) { console.log(`${d.severity}: ${d.message}`); } } // Present only when a .claude-plugin/marketplace.json was found for (const d of result.marketplace?.diagnostics ?? []) { console.log(`${d.severity}: ${d.message}`); } ``` ## License MIT
