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

No annotations are provided, so the description must carry behavioral load. It usefully discloses '1 point per returned record' (a cost/budget behavior) but omits read-only status, authentication needs, rate limits, and pagination behavior beyond what the schema implies.

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 short sentences with zero waste. The resource is front-loaded, followed immediately by the cost notice, which is the most important operational detail.

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 low-complexity retrieval tool with a fully documented schema and no output schema, the description adequately states what is returned (questions and answers) and adds a critical cost note. It could optionally mention read-only behavior or typical result structure, but the essential information is present.

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?

Schema coverage is 100%, so the schema already documents product, max_items, and start_page fully with examples and defaults. The description adds 'by TCIN or URL,' which mirrors the product parameter description and provides no extra syntax or meaning.

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 names the specific resource (customer questions and answers) and the target platform/product (Target product by TCIN or URL). It is clear and distinct from review or recommendation siblings, though it never explicitly names an alternative tool to differentiate.

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 implies usage (retrieve Q&A for a Target product), but gives no explicit when-to-use guidance, prerequisites, or alternatives. The user must infer that this tool is for questions rather than reviews or recommendations.

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