get_track

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

The annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds the useful behavioral detail that the result is 'Full metadata' rather than a subset. However, it does not disclose additional runtime concerns such as authentication requirements or possible error behavior, though these are partly mitigated by the output schema.

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 one short, front-loaded sentence with no filler. Every word contributes to the tool's purpose and usage, matching the simplicity of the tool.

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 single-ID lookup with an output schema and read-only annotations, the description is complete enough for an agent to select and call the tool correctly. The input semantics are clear, and the output schema covers the return structure.

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 0%, so the description must compensate. The only parameter, track_id, is explained as the 'Spotify id', adding platform-specific meaning beyond the schema's generic 'Track Id' title. This is sufficient for a single required parameter, though it does not specify the expected ID format.

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 states a specific verb ('get'), a specific resource ('one track'), and the key access mechanism ('by its Spotify id'). It also clearly disinguishes this from sibling tools like get_album_tracks or get_top_tracks by emphasizing single-track lookup by ID.

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 phrase 'one track by its Spotify id gives clear context for when to invoke this tool: when the agent already knows a specific Spotify track ID and needs metadata for that single track. It does not explicitly name alternatives or exclusions, but the target use case is evident from the wording.

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