rgb_color

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

No annotations are provided, so the description carries the burden of behavioral disclosure. It indicates a pure conversion operation with no side effects, but it does not mention input constraints, what happens if both RGB and hex are provided, or output details beyond the schema.

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 a single, front-loaded sentence that states the function and target without wasted words. It is concise and immediately scannable.

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 conversion utility, the description is minimally sufficient, but it leaves gaps: no guidance on parameter combination, value ranges, hex format, or edge cases. An output schema exists, but the description still needs to clarify the dual input modes.

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 description coverage is 0% and the description only vaguely connects r/g/b to RGB and hex to hex. It does not specify valid ranges (e.g., 0-255), hex string format (e.g., '#RRGGBB'), or how the tool chooses between RGB and hex when both are supplied.

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 a specific verb ('Convert') and resource ('RGB or hex to HWP internal color value'), clearly identifying the tool's exact purpose. It is distinct from siblings like convert_units or document-editing tools.

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 usage context is implied: use this when a color in RGB or hex form needs to be converted to the HWP internal format. However, there is no explicit guidance about alternatives, exclusions, or when not to use this tool.

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