get_track_details

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 returning 'detailed track information including metadata, cue points, and play history,' which hints at read-only behavior, but doesn't clarify permissions, rate limits, error handling, or data freshness. This is a significant gap 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 appropriately sized and front-loaded, starting with a clear purpose statement followed by structured sections for Args and Returns. Every sentence adds value, with no redundant information, though the formatting could be slightly more streamlined.

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 low complexity (1 parameter) and the presence of an output schema (which handles return values), the description is reasonably complete. It covers the core purpose and parameter semantics adequately, though it lacks behavioral details like error cases or usage context, which would be beneficial for full completeness.

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 description adds meaningful context for the single parameter 'track_id' by explaining it as 'The unique track identifier,' which clarifies its purpose beyond the schema's minimal title 'Track Id.' With 0% schema description coverage, this compensates well, though it doesn't specify format or constraints like length or pattern.

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 with a specific verb ('Get') and resource ('detailed information about a specific track'), making it easy to understand what it does. However, it doesn't explicitly differentiate from sibling tools like 'get_track_file_path' or 'search_tracks', which also retrieve track-related information but with different scopes or filters.

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 no guidance on when to use this tool versus alternatives. With siblings like 'get_track_file_path' (for file paths) and 'search_tracks' (for broader searches), there's no indication that this tool is for detailed metadata of a single track identified by ID, leaving the agent to infer usage context.

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