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

Annotations already establish read-only, idempotent, open-world, non-destructive behavior, so the description correctly adds context about result interpretation: results are not personal recommendations and unknown capabilities remain unknown. That is useful expectation-setting, but it does not cover latency, ranking, pagination, or result limits, so it remains at a moderate level.

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 sentences with no filler. The main function is front-loaded, and the disclaimer follows efficiently. Slightly more structure or a parameter hint could improve it without adding much length.

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?

An output schema exists, so return-value details need not be covered. However, with 0% schema description coverage and a sibling search tool, the description should clarify how this differs from toolfound_search_tools and what the pricing filter does. Those omissions leave an agent unable to call it confidently.

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 description coverage is 0%, so the description carries the full burden of explaining the task and pricing parameters. It only implies that the input is a bounded task description and says nothing about the pricing filter or the 500-character limit, leaving both parameters largely undocumented.

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 says it matches a task description against catalogue evidence, which is a specific verb+resource. However, it does not distinguish from the sibling toolfound_search_tools, which sounds like a competing search mechanism. An agent cannot tell from the description alone when to pick this over search_tools.

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?

There is no explicit when-to-use guidance and no mention of alternatives such as toolfound_search_tools or toolfound_get_alternatives. The caveat that results are not personal recommendations implies a usage context, but it does not tell the agent when this tool is the right choice.

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