get_tracks

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

No annotations are provided, so the description carries full burden. It mentions ordering and failure capture but omits details on rate limits, batch size constraints, or authentication requirements, which are critical for a batch fetch tool.

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 very concise but sacrifices necessary detail. It front-loads the purpose but omits parameter explanation, making it insufficiently informative despite its brevity.

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 existence of an output schema, the return values are covered elsewhere, but the description fails to detail input format, error handling specifics, or limits (e.g., maximum array size), leaving significant gaps for a batch tool.

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?

The sole parameter 'values' has zero schema description coverage, and the description does not explain what the array elements represent (e.g., track IDs, URLs). The phrase 'one ordered result per input' hints at mapping but lacks explicit semantics.

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 verb 'Fetch' and the resource 'many tracks', and distinguishes from the single-item sibling 'get_track' by specifying batch behavior.

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 batch usage but does not explicitly state when to use this tool over alternatives like 'search' or individual fetchers, nor does it provide exclusion criteria.

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