lunaar_sketch_to_render

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

Discloses cost (15 credits) and refund policy, but with no annotations provided, other behavioral traits like authentication, rate limits, or side effects are unaddressed. The description adds some value but is incomplete.

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?

Three sentences with zero fluff. Each sentence provides essential information: function, output, and cost/refund. Ideal conciseness.

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 12 parameters, no output schema, and no annotations, the description omits key details like parameter roles, error scenarios, and output format beyond URL. Incomplete given tool complexity.

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 83%, so the schema already documents most parameters. The description does not add additional meaning beyond what the schema provides, earning a baseline of 3.

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 'convert' and resource 'sketch to photoreal render', specifies applicable types (interior/exterior/kitchen), and distinguishes from sibling tools like lunaar_product_shot.

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?

No guidance on when to use this tool versus alternatives such as lunaar_product_shot or lunaar_food_visual. Does not provide context on prerequisites or typical use cases.

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