create_color_swatch

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

No annotations are present, so the description must inform about side effects, permissions, or constraints. It only states 'Create,' implying mutation, but lacks details on whether existing swatches are overwritten, authorization requirements, or if the swatch is immediately available.

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 sentence with no wasted words, achieving conciseness. It could benefit from more structure (e.g., splitting into purpose and usage), but it remains appropriately sized 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?

With 4 parameters, no output schema, and no annotations, the description fails to explain return values, relationship to sibling tools, or behavior beyond creation. For a complete understanding, an agent would need additional information.

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 input schema has 75% description coverage (name, spotColor, colorValues have descriptions; colorModel missing). The tool description adds no parameter information beyond what the schema provides, so it meets the baseline for moderate coverage.

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 'Create a new color swatch' clearly states the action and resource, making the purpose evident. However, it does not differentiate from sibling tools like apply_color or list_color_swatches, which could lead to confusion about when to use this tool versus those.

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 on when to use this tool versus alternatives such as apply_color or list_color_swatches. There are no instructions on prerequisites or typical use cases.

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