isolate_audio

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

With no annotations, the description is the sole source of behavioral disclosure. It states that the tool returns a task id, status, and output URLs, but omits critical behavioral traits such as asynchronous execution, polling behavior, or side effects. This leaves the agent unprepared for the task lifecycle.

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?

The description is one compact sentence that front-loads the key action and return value. It contains no fluff, making it immediately scannable, even though brevity sacrifices depth that other dimensions capture.

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?

The tool has six parameters, no output schema, and no annotations, yet the description fails to explain how parameters interact, what the output URLs contain, or how waiting/polling works. It is a minimal skeleton that leaves substantial gaps for an agent attempting to use the tool correctly.

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 only 33% (wait and model have descriptions), and the tool description adds no parameter explanations. Four parameters (timeout_ms, callback_url, poll_interval_ms, source_audio_url) remain semantically opaque despite being necessary for effective invocation.

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 specifies the action 'Create' on the resource 'a ElevenLabs task on RunAPI (isolate audio)', clearly differentiating it from siblings like text_to_speech or text_to_dialogue. The parenthetical 'isolate audio' removes any ambiguity about the task type.

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?

There is no guidance on when to use this tool versus alternatives. It does not mention use cases, prerequisites, or why isolate_audio would be preferred over sibling tools. The agent is left to infer situational appropriateness from the name alone.

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