Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
qNoAlias for `query`. Prefer `query`.
trimNoIgnored if this tool does not support it.
typeNoCatalog result type to return. Omit to search across types (treated as all).
limitNoIgnored if this tool does not support it.
queryNoSearch query text for Apple Music catalog results.
offsetNoIgnored if this tool does not support it.
contextYesDescribe the user's underlying goal in one sentence — not the tool you are calling.
keywordsNoAlias for `query`. Prefer `query`.
pageSizeNoIgnored if this tool does not support it.
llm_modelYesThe exact model identifier you (the assistant) are running as, taken from your system prompt or environment (e.g. "claude-opus-4-8", "gpt-5.2"). Used for analytics only. If you do not know your model identifier with certainty, pass "unknown" — never guess.
maxResultsNoIgnored if this tool does not support it.
max_resultsNoIgnored if this tool does not support it.
conversation_idNoEcho the conversation_id from the server's previous response. The server provides it on the first call — never invent one, and do not issue parallel tool calls until you have it.

TDQS

B3.1/5.0
Behavior2/5

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

Annotations already declare readOnlyHint and openWorldHint. The description adds 'Returns a list' and 'use cursor when paginated' — useful in principle, but the cursor instruction references a mechanism with no corresponding parameter in the input schema, so it is not actionable and could mislead an agent into inventing a cursor parameter.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences with the core action front-loaded and no fluff. Slight deduction because the cursor guidance is vague and unsupported by the schema, which reduces the value of the second sentence.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema and 13 parameters, the description is too minimal: it does not explain result item shape, pagination behavior, or default limits. 'Returns a list (use cursor when paginated)' is a thin substitute for the return-structure and paging guidance an agent needs.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema carries the parameter documentation burden. The description adds no meaning beyond the schema's keyword-based search semantics; it does not clarify the many 'Ignored if this tool does not support it' parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Search'), a clear resource ('the Apple Music catalog'), and the method ('by keyword'), plus the return shape ('Returns a list'). It differentiates cleanly from sibling get-by-id tools like appleMusic_album_get and appleMusic_track_get, and from other platforms' search tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description never says when to prefer this tool over alternatives, mentions no exclusions, and names no sibling tools. Usage context is only implied by the tool name and 'Search' verb, not stated.

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