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

No annotations are provided, so the description carries the full behavioral burden. It does not state cost, processing time, credit consumption, whether media_key must reference an already-uploaded asset, or the read-only nature of the operation, leaving key behavioral traits undisclosed.

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 front-loaded sentence with no filler; the purpose is stated immediately. It is tight and well-structured, though it could carry slightly more operational detail without bloat.

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?

For a tool with a nested payload, an enum, default values, and no annotations or output schema detail on parameters, the description is too thin. While an output schema exists (so return values need not be described), the input semantics and behavioral context are largely missing.

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 description coverage is 0% and the payload is a nested object. The description's mention of 'shot script or ad-pattern breakdown' loosely maps to the analysis_kind enum, but media_key, focus, and target_duration_seconds (with its 3-15s constraint) are entirely unexplained in either the schema or the description.

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?

States a specific verb (Analyze) and resource (reference video or image) with a named output (shot script or ad-pattern breakdown), which differentiates it from generation siblings like video-generation and image-generation. It does not explicitly contrast with content-analysis, so it falls just short of a 5.

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 phrase 'for generation workflows' implies this is a pre-processing step before generation, giving implied usage. However, it names no alternatives and gives no explicit when-not conditions (e.g., when to use content-analysis instead).

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