playlists_delete

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

With no annotations provided, the description carries the full burden for behavioral disclosure. It reveals the destructive action, quota cost, and authentication requirement, but it does not mention permanence, cascading effects on playlist items, or possible error responses.

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 two short sentences, front-loaded with the primary purpose. Every sentence contributes meaningful information: action, quota cost, and authentication requirement, with no wasted words.

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 simple delete operation with only two parameters and a fully documented schema, the description covers the essential invocation facts: action, required auth, and quota cost. It could add permanence or error behavior, but the current level is sufficient for a basic destructive API.

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 input schema already documents both parameters with 100% coverage, so the baseline is 3. The description adds no parameter-level detail beyond what the schema provides; it only restates general context.

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 opens with the direct action 'Delete a YouTube playlist,' which clearly specifies the verb and resource. It distinguishes this tool from siblings like playlistItems_delete, which targets playlist items rather than playlists themselves.

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 provides useful context such as quota cost and OAuth requirement, but it does not explicitly state when to use this tool over alternatives or give exclusion criteria. Usage is implied by the tool name and purpose rather than explicitly guided.

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