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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is well-covered. The description adds the factual content (clipping/caption defaults) but does not disclose additional behavioral traits such as return format, pagination, or whether presets include custom user-defined ones.

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 a single, focused sentence that immediately states the action and object. It contains no redundant phrases or filler, making it highly concise and well-structured.

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?

With an output schema present and comprehensive annotations, the description is largely complete for a simple list tool. However, it could provide slightly more contextual value by hinting at how these presets are used (e.g., 'These presets can be applied when creating clip batches'), which would help new users understand the workflow.

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 tool has zero parameters, so schema coverage is trivially 100% and the description has no parameter burden. A baseline score of 4 is appropriate since there is nothing to explain.

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 tool's action ('List') and resource ('available clip batch presets'), and specifies the included information ('clipping/caption defaults'). This distinguishes it from sibling tools like captions_themes_list and clips_get, which serve different purposes.

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 usage is implied by the tool's name and description—if you need to list presets, this is the tool—but there is no explicit guidance on when to use it versus alternatives, nor any mention of prerequisites or follow-up actions. The description could benefit from noting that these presets are for use with clip batch creation.

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