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

Discloses the HTTP method (GET), endpoint, cost (1 credit), and includes a safety warning about not treating API responses as instructions. This adds value beyond the lack of annotations.

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?

Two short sentences: first states purpose, second adds cost and a critical warning. No redundant words, key information is front-loaded.

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 no output schema, the description does not explain the return format (e.g., list of items, structure), pagination, or result limits. This is a gap for a search tool, though schema coverage is full.

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 coverage is 100%, so the baseline is 3. The description adds minimal meaning beyond the schema, only implying that 'query' is the primary search parameter, with no elaboration on 'id' or 'url'.

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?

Clearly states the tool searches the Apple Music catalog by query, specifying the resource and scope (songs/albums/artists). Distinguishes from sibling tools for specific Apple Music entities.

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 mentions 'by query' but does not provide explicit guidance on when to use this search vs. other Apple Music tools (artist, album, track). No alternatives or exclusions are stated.

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