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

With no annotations provided, the description carries the full burden. It discloses that the output is for human review and approval, indicating a draft/staging step, and specifies duration and platform constraints. However, it doesn't disclose whether the tool saves files, invokes external models, or has side effects, leaving some behavioral traits opaque.

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?

A single sentence that is front-loaded with the verb and core resource, followed by concise qualifiers (duration, platform, purpose). No wasted words; the description is compact yet information-dense.

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 fully captures the tool's main function and purpose, but given no annotations and no output schema, it could mention what happens after approval or specify what the storyboard keyframes contain (e.g., images vs. text). It's reasonably complete for a script-generation tool, though not exhaustive.

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 covers all four parameters with clear descriptions (100% coverage), so the baseline is 3. The description doesn't add parameter-specific details but aligns with the schema's target_duration_seconds and target_platform. No extra semantic value beyond the schema is provided.

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 'Generate' and clearly identifies the resource as a 'book trailer script and storyboard keyframes' with scope details ('viral 30-45 second social media (TikTok/Reels) cinematic'). It distinguishes from sibling tools like 'generate_storyboard' by combining script and storyboard, and adds the purpose 'for human review and approval'.

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 use for drafting a trailer script and storyboard for human approval, but it does not explicitly contrast with sibling tools like 'generate_storyboard' or 'render_approved_trailer_videos'. No explicit when-to-use vs. alternatives is provided, so guidance is implied rather than direct.

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