video_audio_waveform

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

No annotations are provided, and the description does not disclose what the output contains (e.g., arrays of peaks, silence intervals) or any side effects (none expected). It fails to explain behavior like error handling or performance implications.

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?

Very concise: two sentences, no redundant words. The core action is front-loaded ('Extract audio waveform data').

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 simple tool with two parameters and an output schema (though not shown), the description covers the basic purpose and arguments. However, it lacks usage guidelines and behavioral details, which are important for an agent to invoke it 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?

The input schema has 0% coverage (no descriptions for parameters), so the description adds value by clarifying input_path as an absolute path and bins as number of time segments with a default. However, it does not specify valid ranges or format constraints.

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 'Extract audio waveform data (peaks and silence regions)', which specifies the verb and resource. It distinguishes itself from siblings like video_extract_audio (which extracts the audio track) and audio_compose (which creates audio).

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?

No guidance on when to use this tool versus alternatives (e.g., video_extract_audio, audio_effects). It does not mention any prerequisites, limitations, or exclusion criteria.

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