color_temperature

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

No annotations are provided, and the description does not disclose behavioral traits such as whether it is a pure computation, requires network access, or has any side effects. It does not mention the nature of the output (e.g., a label or range). The minimal description fails to inform the agent about behavior beyond the basic operation.

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 very short (two sentences) without redundancy. It front-loads the purpose and then lists the parameter. While concise, it could benefit from a structured format (e.g., bullet list) for the parameter, but the current form is efficient for a simple tool.

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 has only one parameter, the description is adequate for a simple color analysis tool. However, it lacks additional context such as valid hex range, handling of invalid inputs, or the scale of temperature. The output schema likely covers return values, so that gap is acceptable, but the description could still be slightly more informative.

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 format guidance for the single parameter 'hex_color' ('Hex color without # (e.g. '3498db')'), which is not present in the input schema (0% coverage). This helps the agent construct valid input. The example clarifies the expected format.

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 estimates color temperature (warm/cool) of a hex color, with a specific verb 'Estimate' and resource 'hex color'. It distinguishes from siblings like color_conversion or color_harmony tools. However, it could be more precise about the output format (e.g., categorical label vs numeric value).

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 on when to use this tool versus alternatives (e.g., color_harmony, convert_color). The description does not provide context or exclusions, leaving the agent to infer from the tool name alone. With many color-related siblings, explicit usage tips would be helpful.

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