set_scene_color

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

With no annotations, the description must convey behavioral traits. It explains that color is an index from the 'Ableton color palette,' adding context beyond the schema's integer type. However, it omits whether the operation is reversible, has side effects, or requires specific permissions.

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 very short (two lines) and front-loaded with the purpose. However, it lacks structure (e.g., bullet points) and could be more concise while still covering essential details. It is acceptable but not exemplary.

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 the tool's simplicity (two integer parameters, output schema exists), the description covers basic functionality. However, it does not address error conditions, valid parameter ranges, or how this tool interacts with other scene-related tools, leaving moderate gaps.

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 must compensate. It adds that scene_index is 0-based and color references the 'Ableton color palette,' which provides basic semantics beyond raw schema types. However, it does not specify valid ranges or constraints for either parameter.

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 the color of a scene,' specifying the action (set) and resource (scene color). This distinguishes it from sibling tools that set colors for tracks or clips, as the resource is explicitly different.

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 (e.g., set_clip_color, set_track_color). The description does not mention prerequisites, context, or exclusions, leaving the agent without decision support.

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