TDQS

C2.8/5.0
Behavior2/5

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. The description adds nothing beyond that: it says nothing about default page size, the compact-vs-verbose distinction, whether drafts/private playlists are excluded, or ordering, all of which matter for interpreting results.

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?

One short sentence with no filler and the object of the operation front-loaded. Its brevity is close to the point of under-specification, but nothing written is wasted.

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

Completeness3/5

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

An output schema exists, so return shape need not be described. However, for a three-parameter paginated listing tool sitting among near-duplicate siblings, the definition leaves pagination, the verbose flag, and sibling disambiguation entirely to the schema and tool name.

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

Parameters2/5

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

Schema description coverage is only 33% — only `verbose` is documented, and that documentation lives in the schema rather than the description. Neither `userId` (which accepts string or number) nor `limit` (default 50, max 200) is explained in the description, so it fails to compensate for the coverage gap.

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

Purpose4/5

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

States a specific verb and resource ("List the playlists") with scope "a user has published", which distinguishes it in principle from get_my_playlists. It never names a sibling explicitly and the title's "artist" conflicts slightly with the description's "user", but the operation itself is unambiguous.

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?

No guidance on when to choose this over get_my_playlists, search_playlists, or get_playlist. The agent must infer that this is the 'someone else's published playlists by id' case from the name alone.

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