playlistItems_delete

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 adds useful context about quota cost (50 units) and authentication (requires OAuth access token). However, it does not mention the destructive permanence of the deletion, potential side effects, or error conditions, which would be valuable for a delete operation.

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 concise, front-loaded with the primary purpose, and includes only essential operational details (quota and auth). No wasted words or redundant information—perfectly sized for a simple deletion tool.

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 tool is relatively simple with one required parameter and no output schema, so the description is adequate but not thorough. It lacks information about return values, idempotency, or ownership requirements. Given no annotations to supplement safety or side-effect context, the description could go further (e.g., 'This permanently removes the item') to fully inform the agent.

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 100% with each parameter having a description, so the baseline is 3. The tool description adds no extra parameter semantics beyond what the schema already provides; it doesn't explain the relationship between params or usage nuances.

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 ('Remove a playlist item') and the resource ('from a playlist'), which is specific and distinguishes it from sibling tools like playlists_delete (which deletes an entire playlist). The verb and object are 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?

The description implies usage (when you need to remove a playlist item) but provides no explicit when-to-use or when-not-to-use context relative to alternatives. It mentions the OAuth requirement, which is a prerequisite, but does not offer guidance on when to choose this over other playlist item operations.

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