set_color_value

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

No annotations are provided, so the description must disclose behavior. It fails to mention permissions, effects on existing settings, reversibility, or return values. The description provides no behavioral context whatsoever.

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?

While the description is a single short sentence, it is under-specified rather than concise. It omits essential information and reads as a placeholder, similar to the 'Process' example in the rubric.

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 many sibling color-related tools and no annotations or output schema, this description is completely inadequate. The agent cannot determine how to invoke the tool or what to expect.

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 schema has 0 parameters, so the baseline is 4, but the description should compensate by explaining how the color value is specified. It does not, leaving the agent without any clue about the required input format. The vague 'set color value' adds nothing beyond the tool name.

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 'Premiere Pro expanded operation: set color value' is a tautology that merely restates the tool name. It does not specify what color value is being set, on which target (clip, project, sequence), or how it differs from related tools like set_color_label or color_correct.

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. The description gives no context about intended scenarios, prerequisites, or how it fits into a workflow.

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