Create Render Data

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

Annotations are empty, so the description carries the full burden. It discloses the upsert semantics (update-if-exists) and the return value, which is genuinely useful. However, it does not state behavior on conflict when update_if_exists=false and a name already exists, or any error/permission implications for a mutation tool with zero annotation coverage.

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 two-clause sentence carries the purpose, the upsert behavior, the scope of settings, and the return value with zero filler. Everything earns its place and the central action is front-loaded.

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 12-parameter tool with no output schema and no annotations, the description covers the core purpose, return value, and downstream usage. With full schema coverage carrying parameter meanings, the only meaningful gap is the unspecified behavior when update_if_exists=false collides with an existing name — minor given the required name param provides a natural key.

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% — every one of the 12 parameters has its own schema description — so the baseline of 3 applies. The description only maps the high-level fields (resolution/renderer/fps/frame range) to parameters and adds the handle-return semantics; it does not add syntax or format details 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 states a specific verb+resource ('Create (or update-if-exists) a RenderData') with named fields (resolution/renderer/fps/frame range) in one call. It also names downstream sibling tools (create_take/set_params) for chaining, distinguishing the tool's role from other entity-creation tools in the sibling list.

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?

It hints at usage context by noting the returned handle enables create_take/set_params chaining and that the call consolidates multiple settings 'in one call,' but it never explicitly states when to prefer this over alternatives or when not to use it. No exclusions or alternative-routing guidance is given.

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