Build video ad brief

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

With no annotations, the description conveys key behavioral traits: 'local-only' (no external calls), 'complete' (multiple outputs), and the exclusion of API calls. Could be improved by mentioning no side effects or resource constraints, but sufficient for this context.

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?

Two sentences with front-loaded main action and subsequent listing of deliverables. No fluff; every word adds value. Well-structured for quick comprehension.

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?

Covers the tool's purpose, inputs, and outputs in a general sense. Lacks specifics on return format or additional behavior (e.g., is storyboard generated as text?). But for a tool with 18 parameters and no output schema, the description provides a solid conceptual overview.

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?

Schema coverage is 100%, so baseline 3 is appropriate. The description adds no new per-parameter details beyond the schema. It gives overall context but does not elaborate on any parameter's meaning beyond the schema's already clear descriptions.

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?

Clearly states the tool creates a 'local-only video ad brief' from product details, listing included components (angles, scripts, storyboard, compliance notes, AdsTurbo-ready prompt, follow-up CTA). The phrase 'No AdsTurbo API calls' distinguishes it from the sibling export_adsturbo_prompt tool, which likely makes API calls.

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?

Implied usage: use this tool for local-only brief generation when no AdsTurbo API calls are desired. However, no explicit guidance on when to choose this over siblings like generate_hooks or generate_storyboard. Lacks when-not-to-use and alternative descriptions.

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