video_sync_motion_to_audio

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

With no annotations and no output schema, the description carries the full burden of behavioral disclosure. It indicates a multi-stage mutation involving motion locking, stylization, and muxing, but does not say whether output_video is overwritten, what permissions or files are required, or what the result looks like.

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 definition is a single tightly packed sentence with no filler, and the sequence of operations is front-loaded. It is dense with jargon but not verbose.

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 is complex: 8 parameters, no schema descriptions, no annotations, and no output schema. The description explains the high-level pipeline but leaves most parameter semantics and operational behavior unspecified, so it is not complete enough for reliable invocation.

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 0% across 8 parameters, so the description must compensate. It gives indirect clues for audio_wav, output_video, style, and bass_punch_strength, but says nothing about bpm, factor, phrase_zoom_strength, or how the optional parameters affect the output.

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 uses a specific verb and resource: it locks video camera motion onto a WAV soundtrack and then stylizes and muxes an MP4. That is clear enough to distinguish it from general video conversion or motion analysis tools, though it does not explicitly name any sibling alternative.

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 explicit guidance on when to use this tool versus alternatives such as video_extract_sound_triggers, video_analyze_motion, or video_convert. The use case is implied by the description, but no prerequisites, exclusions, or alternative-selection rules are provided.

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