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

With no annotations, the description offers minimal behavioral detail beyond the core function; it does not disclose whether the process is asynchronous, how long it takes, or any side effects, so the agent is left guessing about the tool's runtime behavior.

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?

One sentence, action-first, with no wasted words; every part contributes meaning.

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 description covers what and how but is thin on operational context; while the output schema could cover return values, the lack of any guidance on prerequisites or edge cases limits completeness for a tool with no annotations.

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 single 'url' parameter has zero schema description, but the description compensates by specifying acceptable URL types (app store link, product screens, GitHub repo URL), giving concrete guidance for what to pass.

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 'Create' and specifies the deliverable '15-second launch video' plus input sources (app store link, product screens, GitHub repo URL), clearly distinguishing it from sibling tools like pika_generate or pika_explainer.

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 have an app store link, product screens, or GitHub URL and want a launch video, but it does not explicitly state when not to use it or mention alternatives, leaving the choice among sibling tools ambiguous.

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