transcribe_audio

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions the payment requirement, which is useful context, but fails to describe other critical traits: whether the operation is synchronous or asynchronous (e.g., returns a job ID), potential rate limits, error handling, or output format (e.g., plain text, JSON). This leaves significant gaps for a tool with no annotation coverage.

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 extremely concise and front-loaded, consisting of two sentences that directly state the purpose and a key requirement. There is no wasted language, and every sentence earns its place by providing essential information efficiently.

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 complexity of an audio transcription tool with no annotations and no output schema, the description is incomplete. It lacks details on behavioral aspects (e.g., processing time, output format), usage constraints (e.g., supported audio types, size limits), and does not compensate for the absence of structured output information, making it inadequate for full agent understanding.

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 100%, so the schema already documents all three parameters (paymentId, audioBase64, language) with clear descriptions. The description adds no additional parameter semantics beyond implying that paymentId must be 'paid,' which is already covered in the schema. This meets the baseline for high schema coverage.

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 states the tool's purpose: 'Transcribe audio to text.' It specifies the verb ('transcribe') and resource ('audio'), making the function unambiguous. However, it does not differentiate from siblings like 'synthesize_speech' (which does the reverse) or 'convert_file' (which might handle audio differently), leaving room for improvement in sibling distinction.

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 implied usage guidance by stating 'Requires a valid paid payment ID,' indicating a prerequisite for use. However, it does not explicitly mention when to use this tool versus alternatives (e.g., 'synthesize_speech' for text-to-audio or 'convert_file' for format conversion) or any exclusions, such as file size limits or supported audio formats.

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