get_track

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

With no annotations, the description carries the full burden of disclosing behavior. It states what is returned but does not mention read-only nature, authentication requirements, error handling, or side effects. The description is minimal and adds little beyond the obvious 'return' semantics.

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 sentence with no filler. It front-loads the action and lists the return contents efficiently. Every word earns its place, and the structure is clean.

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?

For a simple getter with an output schema, the description is minimally adequate. It specifies the kinds of returned data, so an agent knows what to expect. However, it does not mention the need for track_id (though in schema) or differentiate from siblings, leaving contextual gaps for correct usage.

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 schema has 0% description coverage, and the description does not explain track_id. It implies that a track is identified, but does not specify the format, source, or any constraints. The description adds no meaning beyond the parameter name and type, failing to compensate for the schema's lack.

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 'Return' and the resource 'one track', listing the types of data (metadata, license string, attribution text, URLs). It is specific and not a tautology, but it does not explicitly differentiate from siblings like search_music or status, which could also involve track data.

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. There is no mention of prerequisites, such as having a track_id, nor any comparison with sibling tools like search_music (which likely returns multiple tracks) or status. The usage context is entirely implicit.

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