mirelo_extend_audio_with_video_generate

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

Mentions synchronous operation and return of result URLs, adding some behavioral context. However, lacks details on job creation, side effects, or whether it's blocking. Adequate given no annotations.

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?

Extremely concise with three sentences covering purpose, output, and requirements. Every sentence adds value; no redundancy.

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 7 params, nested objects, and no output schema, the description covers the essential purpose, required inputs, constraints, and synchronous nature. Could mention output format but overall sufficient.

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%, descriptions already cover parameters. The description reiterates key constraints (duration range and model version) but does not add significant new meaning 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?

Clearly states the verb 'Extend' and the resource 'audio input with video conditioning'. Differentiates from siblings like mirelo_extend_audio_generate by specifying video conditioning and synchronous behavior.

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?

Implies usage for extending audio with video conditioning, but does not explicitly state when to use this vs. alternatives (e.g., mirelo_extend_audio_generate). No when-not guidance provided.

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