get_track_details

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

No annotations are present, so the description carries the burden. It discloses that the tool returns metadata, cue points, and play history, suggesting read-only behavior. However, it does not mention potential errors, permissions, or side effects. For a straightforward read operation, this is sufficient but not rich.

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 concise and well-structured with an Args/Returns format. Every sentence adds value—purpose, parameter explanation, and return summary. No fluff or repetition.

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?

With a single required parameter and an output schema present, the description does not need to over-explain. It provides the essential context: what the tool does and what the parameter means. The mention of specific return fields (metadata, cue points, play history) adds completeness, making it fully understandable for an agent.

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 meaning beyond the schema by explaining that track_id is 'the unique track identifier,' whereas the schema only provides the type and name. With only one parameter, this clarification is valuable. Schema description coverage is 0%, so this description is the only source of parameter 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 tool's function: 'Get detailed information about a specific track.' It names the specific resource (track) and the action (get details). It distinguishes itself from siblings like get_track_file_path by mentioning additional fields (metadata, cue points, play history), though it does not explicitly contrast with alternative tools.

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 when to use this tool: when you need detailed info for a single track. It does not explicitly state when not to use it or mention alternative tools. Sibling tools like search_tracks suggest broader retrieval, but no exclusion is provided. The guidance is adequate for a simple getter but lacks explicit direction.

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