set_clip_color

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

No annotations are provided, so the description carries the full burden. It does not disclose any side effects (e.g., overwriting previous color), error conditions for invalid color index, or whether the tool only works on session clips. This lack of behavioral context for a mutation tool is a significant gap.

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 and well-structured. Three short sentences and a simple list convey the essential information without any unnecessary text.

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 tool with no output schema and no annotations, the description is adequate but not thorough. It explains the basic action and gives the color range, but it omits details like indexing start (likely 0) and whether the clip must be in a specific state. Given the lack of schema descriptions, more context would be helpful.

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 value for the 'color' parameter by specifying the valid range (0-69 in Ableton's color palette), which is absent from the schema. However, track_index and clip_index are only listed by name with no additional meaning, such as that they are zero-based indices. With 0% schema coverage, the description partially compensates but not fully.

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: setting a clip's color. The verb 'set' and resource 'color of a clip' are specific and distinct from sibling tools like get_clip_color, set_clip_gain, etc.

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 information is provided about when to use this tool versus alternatives, such as requiring the clip to exist or the track to be loaded. There is no guidance on prerequisites or fallback options.

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