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

The description discloses important behavioral traits: it starts an async render, returns a job to poll, and instructs the agent to use neuron_studio_render_status until completion. It also surfaces the Pro+ plan requirement, adding meaningful context beyond the sparse annotations. No contradiction with annotation flags.

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?

Four dense sentences with no filler: core function, return contract, polling flow, example use case, and a plan requirement. The most important information is front-loaded and every sentence 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?

For a fairly complex tool with no output schema and 5 parameters, the description covers the essential flow: what it produces, how to get the result, and a usage example. It stops short of explaining behaviors around editing an existing doc or side effects, but the schema and clear description cover most gaps.

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 coverage is 100%, so the baseline is 3 and the schema carries the parameter documentation burden. The description reinforces the intent via 'prompt' and '20s TikTok reel', which maps to instruction, platform, and durationSeconds, but it does not add new semantic detail 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: 'build/edit a video from a prompt AND start the MP4 render.' It clearly differentiates the tool as a one-shot combined build+render operation, which stands apart from sibling tools like neuron_studio_generate_video or neuron_studio_render that likely handle only one phase.

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 gives a concrete, memorable use case ('make me a 20s TikTok reel about X') and implies when to use the tool for end-to-end video creation. It does not explicitly name alternatives or give when-not-to-use conditions, but the 'one-shot' framing provides clear contextual guidance.

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