get_category_playlists

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

With no annotations provided, the description carries the full burden of behavioral disclosure. The '(GET /browse/categories/{id}/playlists)' endpoint reference does usefully signal that this is a read-only operation, which is the key safety-relevant trait. However, it discloses nothing further — no pagination behavior across pages, no country-availability caveats, no note about how response_format changes output shape. The GET signal earns partial credit, but the rest is left to the 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?

A single sentence with the verb and resource front-loaded, plus a parenthetical endpoint reference that earns its place by pinning the exact API call. No filler words, no repetition of schema content. This is appropriately minimal without being under-specified.

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 the moderate complexity (6 params, 1 required), the rich 100%-covered schema carries most of the invocation burden, and the description handles the core purpose. But with no annotations and no output schema, the description is thin: it omits usage guidance, pagination expectations across the limit/offset/max_results interplay, and any behavioral caveats. It is minimally viable but has clear gaps for such a tool in a large toolset.

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 the schema already documents all six parameters thoroughly, including defaults, ranges, enums, and the source of category_id. The description adds no parameter-level meaning beyond the general 'for a browse category' scope. Baseline 3 is appropriate when the schema does the heavy lifting.

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 and resource: 'Get playlists for a browse category', which clearly identifies the operation. The endpoint reference (GET /browse/categories/{id}/playlists) adds precision and implicitly distinguishes this from siblings like get_categories (which returns categories, not playlists) and get_playlist (a single playlist by ID). However, it does not explicitly contrast with related siblings such as browse_category_deepdive, so it misses the top bar for sibling differentiation.

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 offers no guidance on when to use this tool versus alternatives — no mention of get_categories for discovering category IDs, no exclusions, and no note on when browse_category_deepdive would be more appropriate. The only hint is buried in the schema's category_id description ('from get_categories'), which is not part of the description itself. An agent picking between the many playlist- and category-related siblings gets no routing help.

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