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 cost ('1 credit per scene') and authentication needs ('Requires PIXELPANDA_API_TOKEN'), which are valuable behavioral traits. However, it misses details like rate limits, response format, or whether it's an async operation (though output schema might cover this), leaving gaps in transparency.

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 front-loaded with the core purpose, followed by key constraints and requirements in two short sentences. Every sentence adds value: the first defines the tool, the second covers cost and authentication. There is no wasted text, making it highly efficient.

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?

Given no annotations, 0% schema coverage, but an output schema exists, the description is partially complete. It covers purpose, cost, and auth needs, but lacks parameter explanations and behavioral details like error handling. The output schema may help with return values, but overall completeness is moderate for a tool with multiple parameters and no annotation support.

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%, so the description must compensate. It provides no information about the three parameters (product_uuid, num_scenes, category), such as what a product_uuid is, how num_scenes relates to credits, or what categories are available. This leaves parameters largely unexplained beyond the schema.

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 clearly states the verb 'Generate' and the resource 'AI product scene photos', specifying the types (lifestyle, studio, detail shots) and excluding avatars. It distinguishes from sibling tools like 'generate_product_photo' by focusing on scenes rather than single photos, but doesn't explicitly contrast with all siblings.

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 for generating product scenes and mentions 'No avatar needed', which suggests when not to use it (if avatars are required). However, it lacks explicit guidance on when to choose this over alternatives like 'generate_product_photo' or other image tools, and doesn't mention prerequisites beyond the API token.

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