spotify_update_playlist

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

With no annotations, the description carries full burden. It indicates mutation ('Update') but discloses no side effects, authentication needs, rate limits, or return value behavior. The existence of an output schema is not leveraged to explain return data.

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 that efficiently communicates the tool's purpose and editable fields with no unnecessary words. Perfectly concise.

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 tool's simplicity, the description covers the main aspects but lacks details on permissions, error handling, and data returned. For a mutation tool with no annotations and 0% schema coverage, it provides minimal but acceptable completeness.

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 coverage is 0%, but the description lists the three editable parameters (name, description, public), which adds meaning beyond the schema titles. However, it does not elaborate on expected formats or constraints (e.g., string length) and does not clarify the required playlist_id parameter beyond being an identifier.

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 action verb 'Update' and specifies the resource 'playlist' with the exact attributes (name, description, public/private visibility). This distinguishes it from siblings like spotify_create_playlist (creation) and spotify_add_to_playlist (adding tracks).

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 usage when one wants to modify those attributes but provides no explicit guidance on when to use versus alternatives, prerequisites (e.g., ownership or edit permissions), or when not to use. No when-not or alternative mentions.

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