check_gitignore_coverage

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full responsibility. It discloses the key behavior (flags files that could be accidentally committed) but omits details about read-only nature, return format, or potential false positives. This is adequate for a simple check tool but not thorough.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two focused sentences: the first defines the tool's purpose with examples, the second explains the flagging behavior. No redundant information or filler words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description only vaguely says 'flags files' without specifying return format or prerequisites. This is minimally sufficient for a single-parameter tool, but additional details about output or limitations would improve completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema provides a complete description for the only parameter ('Absolute path to the project root'), so the description adds no additional parameter semantics. Baseline 3 applies due to high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool checks whether sensitive files are covered by .gitignore rules, naming specific examples (.env, secrets.json). It distinguishes itself from sibling scan tools by focusing on coverage rather than content scanning.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context for when to use the tool: to verify sensitive files are protected from accidental commits. It doesn't explicitly name alternatives or exclusions, but the distinction from sibling scan tools is implied.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
