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

There are no annotations, so the description carries the behavioral disclosure burden. It adds a useful detail by noting that the response 'Includes the answers that are no,' which clarifies the output scope. However, it does not mention whether the operation is read-only, requires authentication, or has any other behavioral caveats.

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?

The description is concise and front-loaded with the core purpose. The phrase 'questions it exists to answer' is slightly indirect, but the meaning is understandable and the additional note about 'no' answers is valuable without being verbose.

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?

For a zero-parameter, read-style tool with no output schema, the description gives enough context about the resource and intended use. It could mention response format or size, but the tool's simplicity makes the current description reasonably complete.

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 tool takes zero parameters and schema description coverage is 100%, so the schema already exhaustively documents the input surface. The description adds nothing about parameters, but none is needed; the baseline of 4 is appropriate.

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 defines the resource as FillTrust's own security posture answers, with a specific audience ('anyone assessing it as a vendor'). The title reinforces the read action, and the description distinguishes this from sibling tools that inspect questions or standards rather than FillTrust's own responses.

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 this tool: when assessing FillTrust as a vendor and wanting its own self-reported posture. It does not explicitly mention alternatives or exclusions relative to get_question, search_questions, or list_standards, so it stops short of full routing guidance.

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