Delete playlist

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

Annotations already declare destructiveHint=true and idempotentHint=true. The description adds 'permanently', which reinforces the destructive nature but does not disclose additional behavioral traits such as cascading effects or authentication requirements. Given the annotation coverage, the description provides minimal added value.

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 description is extremely concise at one sentence, front-loading the key action. However, it is too brief to be fully effective, sacrificing completeness for brevity. A more structured description could include the parameter without adding much length.

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 (one required parameter, no output schema, annotations present), the description is insufficient. It fails to explain the parameter's role, usage context, or any behavioral expectations beyond what annotations already provide. For a complete tool definition, the description should at least mention 'playlistId'.

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?

With schema description coverage at 0%, the description must explain the parameter 'playlistId' but does not mention it at all. The description only states 'Delete a playlist permanently', leaving the agent to infer that an identifier is needed. The baseline would be higher with 0 parameters, but here a required parameter exists and is undocumented in the description.

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 uses a specific verb 'Delete' and resource 'playlist', clearly indicating the action. It distinguishes the tool from siblings like 'create_playlist', 'update_playlist', and 'get_playlist', making its purpose unambiguous.

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?

No guidance is provided on when to use this tool versus alternatives such as 'update_playlist' to hide a playlist. There is no mention of prerequisites, consequences, or when not to use it.

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