    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Check an agent rules file (CLAUDE.md, AGENTS.md, system prompt) for 12 safeguards an unattended agent needs (kill switch, spending limit, untrusted-input rule, secrets, memory, audit...). Keyword checks: they report what is written down, not what is enforced. Also flags live-looking API keys and hardcoded URLs/IDs that can go stale. Pass the file's text; nothing is stored.

    Annotations the server declares

    • title: Lint an agent rules file
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
