select_clips_by_color

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

With no annotations, the description must disclose behavioral traits on its own, but it only repeats the tool's name without explaining what 'color' refers to (label color, lumetri, etc.), whether it operates on the timeline or bin, or if a selection is required. It adds no behavioral context beyond the name.

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 with no wasted words or filler. It is front-loaded and easy to scan, appropriate for a simple tool.

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?

Given there are no annotations or output schema, and the tool is one of many selection tools, the description is incomplete. It fails to explain what 'color' means, how the selection is performed, or any side effects. The lack of detail makes it insufficient for an agent to know how to invoke it correctly without further context.

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 tool has zero parameters, so the baseline is 4. The description does not need to explain parameters, and it doesn't mislead. However, it also doesn't clarify how the color is determined (e.g., from selected clips or a property), which is not a parameter issue but a missing explanation.

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 action ('select clips') and the specific criterion ('by color'), distinguishing it from sibling tools like select_clips_by_name and select_all_clips. The verb-resource pair is specific and unambiguous enough to convey the core function.

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 on when to use this tool versus alternatives, nor any exclusions or prerequisites. The description offers no context for when 'select by color' would be appropriate compared to other selection tools.

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