## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2024-11-05; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: score_skill (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); lint_frontmatter (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); validate_skill (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 404 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 4, about 404 tokens to load them all
- tool set hash: c5bafa6c71db5f6b67c27256934e8ec7
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.lazymac2x/claude-skill-validator.svg)](https://protogrid.dev/servers/io.github.lazymac2x/claude-skill-validator)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `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.
- `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.
