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

With no annotations, the description alone must disclose behavioral traits. It reveals nothing: no mention of input requirements (even though schema has zero params), output format, side effects, or access restrictions.

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 a single word, which is under-specification rather than conciseness. It does not front-load essential details, and every sentence (the only one) does not earn its place by adding useful information.

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?

Given the tool's likely role as a speech generation endpoint and the lack of output schema or annotations, the description is completely inadequate. It does not help an agent understand what the tool does or when to use it.

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?

There are zero parameters, so schema coverage is trivially 100%. The description adds no value beyond the schema, merely stating 'Speech'. Per baseline rule for 0 params, score could be 4, but the description fails to provide any meaningful context, warranting a lower score.

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 'Speech' is a tautology that simply repeats part of the tool name without specifying the verb or resource. It fails to state that this tool generates speech audio from text, which is its likely purpose based on naming convention. It does not distinguish from sibling tools like 'transcription_api_v1_audio_transcriptions_post'.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., transcription for audio-to-text, or other audio config tools). There is no mention of prerequisites, context, or exclusions.

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