Create Render Data

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

With no annotations, the description discloses the 'update-if-exists' behavior and return handle, but lacks details on side effects like overwriting existing data, error cases (e.g., name exists without update_if_exists), or permissions. It is adequate but not comprehensive.

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 no fluff: the first conveys core action and parameters, the second adds return value and chaining. Every phrase earns its place.

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 12 parameters and no output schema, the description covers key aspects (upsert behavior, return handle, chaining). It omits parameter interaction details (e.g., frame_sequence defaults) and error handling, but schema fills many gaps, making it fairly complete.

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 100%, so the schema thoroughly defines each parameter. The description adds little beyond grouping parameters (resolution, renderer, fps, frame range) and noting chaining, providing marginal extra value.

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 action ('Create or update-if-exists') and the resource ('RenderData'), listing key parameters (resolution, renderer, fps, frame range) in one call. It also mentions the return value and chaining with sibling tools, distinguishing it from general 'create_entity'.

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 use as an entry point by mentioning 'one call' and chaining with 'create_take/set_params'. However, it does not explicitly state when to use this tool versus alternatives like 'set_params' for modifications, leaving some ambiguity.

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