spotify_update_playlist

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

No annotations are provided, so the description carries the full behavioral burden. It names the mutable fields but says nothing about permission requirements, ownership restrictions, whether omitted fields are preserved (partial update), or reversibility of changes like flipping a playlist to private.

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 compact sentence fragment with the resource and field list front-loaded and no filler. It is efficient, though it is terse to the point of omitting context an agent may need.

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 no annotations and no output schema, the description omits key operational facts: required OAuth scopes/ownership, partial-update semantics for omitted fields, and side effects of public/collaborative toggling. It is incomplete for the tool's complexity.

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 five parameters including the collaborative-must-be-non-public constraint. The description's field list is redundant with the schema and adds no format or syntax detail, so the baseline 3 applies.

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?

States a specific verb (update) and resource (playlist details) plus the affected fields (name, description, public/private, collaborative). It is clearly distinguishable from spotify_create_playlist and spotify_delete_playlist, though it doesn't explicitly name the sibling it differs from.

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 when-to-use guidance, no mention of prerequisites (e.g., ownership or scopes), and no alternatives referenced. Usage is only implied by the verb 'update' and the sibling list context.

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