set_clip_audio

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

Annotations only provide destructiveHint: false, indicating safety. The description adds valid ranges for parameters (e.g., gain 0-1, pitch_coarse -48..48) but does not disclose side effects, error behavior, or permissions. Sufficient for a simple setter but minimal extra context.

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?

One efficient sentence listing properties with ranges. No fluff, but could benefit from structuring as a list for readability. Front-loaded with the primary purpose.

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?

With 7 parameters, output schema exists, and the description covers most parameter semantics. However, it does not mention output, error conditions, or parameter interactions (e.g., effect of setting warp_mode when warping is false). Adequate but not exhaustive.

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 0%, so the description carries the burden. It explains gain range, pitch units, warping boolean, and warp_mode enumeration values. Missing only track_index and clip_index, which are self-explanatory. Adds significant 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?

The description clearly states 'Set audio-clip properties' and enumerates specific audio parameters (gain, pitch, warping, warp_mode), distinguishing it from siblings like set_clip_color or set_clip_name.

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 like set_clip_loop or set_clip_trigger_quantization. The description assumes the agent knows to use it for audio clip settings, but no explicit context or exclusions.

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