set_scene_color

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

With no annotations provided, the description carries the full burden for behavioral disclosure. It does add the useful constraint that color is 0-69 in Ableton's palette, but it omits potential side effects, error behavior, whether the change is immediately applied or undoable, and what happens if scene_index is invalid. This is minimal transparency for a mutation tool.

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 concise and front-loaded with the core purpose. The parameter bullet list is efficient and free of fluff. Every sentence contributes to understanding the tool, making it easy to scan.

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 parameters, no output schema), the description covers the essential semantics. However, it lacks contextual details such as whether scene_index is zero-based, what happens on out-of-range input, or whether the operation is reversible. This is a simple tool, so some gaps are acceptable, but a fully complete description would mention these constraints.

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 adds meaningful semantics beyond the bare schema: it explains that scene_index is 'the index of the scene' and color is 'the color index (0-69)' in Ableton's palette. This compensates for the 0% schema description coverage. However, it does not explicitly state whether scene_index is zero-based, which is a common ambiguity in Ableton APIs.

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 function: 'Set the color of a scene.' It uses a specific verb (set) and resource (scene) with the property (color). This distinguishes it from sibling tools like set_track_color or get_scene_color.

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 about when to use this tool versus alternatives. There is no mention of prerequisites, such as scene existence, or any cue that one should use a getter first to verify the index. The description merely states the operation without contextual usage notes.

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