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

With no annotations, the description bears full burden for behavioral transparency. It only states the basic function without disclosing any behavioral traits such as generation time, cost, success/failure handling, or return format. This is insufficient for responsible agent use.

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 very concise at one sentence, but given the tool's complexity (9 parameters), it is too brief. While front-loaded with the core action, it sacrifices necessary detail for brevity.

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?

Considering the tool's complexity (9 parameters, no output schema, no annotations), the description is critically incomplete. It lacks details on output, behavior, parameter effects, and usage context, making it inadequate for correct agent selection and invocation.

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%, yet the description adds no value by explaining parameters like enhancePrompt, autoDownload, includeFullData, or personGeneration. Agents must infer meaning from names alone, risking misuse. At minimum, key parameters should be explained.

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 'Generate a video from a text prompt' clearly states the verb (Generate) and resource (video from text), distinguishing it from siblings like generateImage (image from text) and generateVideoFromImage (video from existing image). It's specific and unambiguous.

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 provides no guidance on when to use this tool vs alternatives. It doesn't mention scenarios, prerequisites, or exclusions, leaving the agent without context for appropriate usage.

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