add_audio_keyframes

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not explain whether existing keyframes are overwritten or appended, what constraints apply to audio levels, or what happens if the clip is not an audio clip. The description is minimally informative but not misleading.

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 a single, concise sentence that communicates the core purpose without unnecessary words. It is appropriately sized for a simple tool, though it could include a bit more behavioral context without becoming bloated.

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 a simple schema with fully documented parameters, but there are no annotations and no output schema. The description does not cover when to use this tool, how it interacts with existing keyframes, or any prerequisites, leaving an agent with gaps in deciding whether and how 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 provides full coverage for both parameters, including time in seconds and audio level in dB. The description adds slight value by framing the keyframes as enabling 'dynamic volume changes,' but it does not add meaning beyond the schema's descriptions.

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 the tool's action: adding keyframes to audio levels for dynamic volume changes. It identifies the verb ('adds'), the resource ('audio levels'), and the purpose ('dynamic volume changes'), making it distinguishable from generic keyframe tools like add_keyframe, though it doesn't explicitly name any sibling.

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 is provided about when to use this tool versus alternatives such as add_keyframe, set_clip_volume, or adjust_audio_levels. The description only states what the tool does, not the conditions that make it the right choice.

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