- **warn** Mentions of other tools or servers in `validate_skill` ([tool-shadowing](https://anlyon.dev/methodology#tool-shadowing))

```untrusted-server-text
The input schema at properties.tools.description contains "override tool", wording about other tools or servers.

inputSchema.properties.tools.description: "Optional override tool list if not declared in frontmatter"
```


## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `lint_frontmatter`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

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

### `scan_security`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

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

### `score_skill`

- The description's first verb is "run": a word for a change.

Description, as the server wrote it:

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

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `validate_skill`

- The name "validate_skill" says "validate": a word for reading.
- Findings: warn tool-shadowing

Description, as the server wrote it:

```untrusted-server-text
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.
```
