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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered externally, yet the description contributes no additional behavioral context. It says nothing about result shape, pagination, the multi-section nature hinted at by parameters like 'limit per section', or that results span artists/authors/audiobooks. Nothing beyond the two-word label is disclosed.

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 words are technically concise but this is under-specification, not economy of expression. There is no structure to front-load and no sentence that earns its place beyond the name.

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 an 11-parameter, open-world search tool with an output schema, the description is wholly inadequate. It omits scope, result sections, and any hint of the wide option surface (authors, audiobooks, pre-releases, concert fields) the schema exposes, leaving the agent with no basis for correct invocation.

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 100%, so all 11 parameters are already documented in the schema, which sets the baseline of 3. The description adds no meaning beyond the schema, but per the rubric the high coverage justifies a baseline 3 rather than a penalty.

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 only restates the tool name, 'Spotify album search.', giving a verb and resource but nothing beyond the identifier. It does not distinguish this tool from siblings such as spotify_artist_albums, spotify_album_tracks, spotify_search, or spotify_audiobooks_search, so an agent gains nothing it could not infer from the name alone.

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?

There is no guidance on when to use this tool versus the many other Spotify search tools. The agent is left to infer that this searches albums from the name, but nothing states the conditions, alternatives, or exclusions that would route a query correctly.

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