set_scene_color

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

With no annotations, the description carries the burden of behavioral disclosure. It only mentions the color palette range (0-69), but does not disclose side effects, error behavior on invalid scene_index, whether the operation is destructive, or any return value.

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 extremely concise, with a single purpose sentence followed by a compact parameter list. No wasted words or repetition of schema fields.

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?

For a simple setter with two parameters, the description is mostly complete, but it lacks details on index base (0 vs 1) and expected behavior on invalid input. There is no output schema, so return behavior is unaddressed, but this is typical for mutation tools. Overall, it's minimally viable with clear 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?

The schema provides only types and titles, so the description adds critical meaning: scene_index is 'the index of the scene' and color is 'the color index (0-69 in Ableton's color palette)'. This compensates for the 0% schema coverage, though scene_index semantics (zero-based vs one-based) remain unclear.

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 tool's purpose with a specific verb and resource: 'Set the color of a scene.' This distinguishes it from siblings like set_clip_color (scene vs clip) and get_scene_color (set vs get).

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?

The description gives no guidance on when to use this tool versus alternatives. It does not mention related tools like get_scene_color or set_clip_color, nor any prerequisites or conditions for use.

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