updatePlaylist

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

No annotations are provided, so the description carries the full burden. It discloses that the tool updates playlist metadata but does not explain whether unspecified fields are preserved, if changes are reversible, or what permissions are required. This lacks sufficient behavioral detail for a mutation tool.

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 concise sentence that front-loads the action and resource. Every word adds value, and the parenthetical field list is efficiently integrated without redundancy.

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?

The description is adequate for a simple metadata update given the rich schema coverage, but it omits important operational context like partial update semantics and return behavior. With no output schema and no annotations, the description could provide more guidance on what to expect.

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?

The input schema documents all five parameters with 100% coverage, so the description adds little beyond listing the fields in parentheses. It provides no additional nuance such as value constraints or relationship between 'public' and 'collaborative'. Baseline 3 is appropriate given high schema coverage.

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 clearly states the verb 'Update' and the resource 'details of a Spotify playlist', listing the specific fields affected (name, description, public/private, collaborative). This distinctly differentiates it from sibling tools like createPlaylist, getPlaylist, and addTracksToPlaylist.

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 implies use for modifying playlist details, which provides clear context relative to siblings. However, it does not explicitly state when not to use it or name alternative tools for similar operations (e.g., reorderPlaylistItems for track order).

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