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

No annotations are provided, so the description carries the full burden of disclosure. It specifies the output duration (15 seconds) and accepted source types, but omits behavioral traits such as authentication requirements, processing time, error handling, or any side effects. This is insufficient for a tool with no other behavioral hints.

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, well-structured sentence of 14 words. It is front-loaded with the core action and resource, with no redundant or superfluous information.

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 has one parameter, an output schema (not shown but exists), and simple behavior, the description covers the key input types and output duration. However, it lacks usage guidelines and behavioral transparency, leaving gaps for an agent to make fully informed decisions.

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 provides only a 'url' parameter with no description (0% coverage). The description compensates by clarifying that the URL can be an app store link, product screens, or GitHub repo URL, adding meaningful context beyond the raw schema.

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 verb 'Create', the resource '15-second launch video', and the source types 'app store link, product screens, or GitHub repo URL'. This distinguishes it from sibling tools like pika_explainer or pika_build_brand, which have 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 description does not provide any guidance on when to use this tool versus its siblings (e.g., pika_explainer, pika_build_brand). No explicit 'when-not-to-use' or alternative recommendations are given, leaving the agent to infer usage context.

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