track_set_color

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

No annotations provided, description only states the action ('set track color') without additional behavioral details like side effects, permissions, or error conditions. The burden on the description is high due to missing annotations, but it adds no extra context.

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?

Two sentences plus a clear bullet list of arguments. Every sentence adds value: purpose, usage guidance, and parameter details. No superfluous 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?

The tool is simple (set color) and the description covers action, usage context, and parameter details. Does not mention error handling or return values, but given no output schema and straightforward nature, it's mostly complete.

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 description compensates by clarifying '0-based track index' and ranges '0-255' for RGB values, adding critical meaning beyond raw schema types and names.

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 states 'Set track color (RGB 0-255)' with a clear verb and resource, and distinguishes from the sibling 'configure_tracks' for batch operations.

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?

Explicitly suggests 'Prefer configure_tracks for batch', guiding when to use this tool for single track color changes versus batch operations. No when-not-to-use but clear implicit guidance.

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