update_playlist

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. It correctly indicates this is a mutation operation, but it omits important context such as whether playlist ownership or existing playlists are required, how partial updates are applied, or what the response indicates.

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?

The single sentence is compact, front-loaded with the action, and contains no filler. It is appropriately sized, though its brevity contributes to the lack of deeper usage and behavior guidance.

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 a mutation tool with 4 parameters, no annotations, and no output schema, the description is too thin. An agent would still need to infer preconditions, determinism of the operation, and the meaning of the response, so the description does not fully support 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?

The schema has 0% description coverage, so the description must compensate. It does map three parameters to their meaning: name to renaming, description to changing the description, and public to visibility. However, it does not explain playlist_id beyond the schema and provides no detail about how omitted parameters behave, leaving some semantics implicit.

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 identifies the operation: renaming a playlist or changing its description/visibility. It is specific enough to distinguish this from creation, deletion, and track-management tools, though it does not explicitly name any sibling tools or state that it only affects playlist metadata.

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 intended use is implied by describing the exact actions: use this tool when a playlist's name, description, or visibility needs to change. However, there is no explicit guidance about when not to use it, or why an agent should choose this over create_playlist, delete_playlist, add_tracks, or remove_tracks.

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