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

The description adds meaningful context beyond annotations: it discloses a $0.02/call cost and x402 (USDC on base), and states the actor is unofficial and independent. The schema description adds that titles are matched deterministically and only selected documents are validated. This complements the annotations (readOnlyHint=false, idempotentHint=false) without contradiction.

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, containing three distinct segments: purpose, independence disclaimer, and cost. Each adds value and the purpose is front-loaded. The first sentence could be more precise, but overall it is well-structured and free of filler.

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?

There is no output schema, so the description should indicate what the tool returns, but 'action evidence' is vague and no result structure is described. While parameter details are well-covered by the schema, the overall behavior and return format are insufficiently explained for an agent to fully anticipate the outcome.

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?

All 7 parameters have descriptions in the input schema (coverage 100%), so the schema provides the necessary meaning. The main description does not add parameter-level details, and the baseline for high schema coverage is 3. No extra value is contributed by the description.

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 'Turn today’s allowed official publications into watchlist-linked action evidence' identifies a specific transformation and resource, and clearly differentiates from sibling tools focused on jobs or real estate. The phrase is slightly metaphorical, but the schema description 'Matches customer watch rules against one official Turkish Gazette issue' adds precision. The tool's purpose is clear enough for selection.

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 no explicit guidance on when to use this tool versus alternatives. It mentions 'today’s allowed official publications' which implies daily use, but there are no exclusions or reference to sibling tools. An agent must infer the use case primarily from the tool name.

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