set_clip_color

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

Annotations declare destructiveHint=false, and the description adds the color index range (0-69), which is helpful. However, it does not disclose other behavioral details such as what happens if an invalid index is provided, or whether the change is immediate/audible.

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?

A single sentence of 12 words, front-loaded with the action and key constraint. Every word is necessary and there is no redundancy.

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 simple (3 required integer parameters) and has an output schema (though not shown). The description provides the essential color range but omits context about track and clip indexing, which could lead to errors.

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 description explains the color_index parameter (0-69), but fails to clarify track_index and clip_index (e.g., whether they are zero-based, or how to identify specific clips). With 0% schema description coverage, the description should compensate but only partially does.

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 'Set' and clearly identifies the resource 'clip's color', including the valid range for color index (0-69). It effectively distinguishes the tool from related siblings like set_track_color and 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?

There is no guidance on when to use this tool versus alternatives. Among siblings, set_track_color sets a track's color, and other tools modify clips, but no disambiguation or context is provided.

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