create_color_swatch

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 only implies mutation ('create') without disclosing side effects, permissions required, whether swatches are document-global, or any limits. This leaves the agent without crucial behavioral insights.

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 only one sentence and very concise. However, it is under-specified—it earns its place but could include additional context (e.g., what a swatch is used for) without significant bloat. Front-loaded but minimal.

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 5 parameters, 4 required, no output schema, and no annotations, the description fails to explain return values, success/failure behavior, or constraints. It is insufficient for comprehensive tool use.

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 80% (4 of 5 parameters have descriptions), providing adequate parameter details. The description adds no extra meaning beyond the schema, but since the schema already covers most parameters, a baseline score of 3 is appropriate.

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 color swatch' explicitly states the verb and resource, distinguishing it from sibling create tools that target other entities (e.g., create_character_style). However, it lacks detail on what a color swatch is or its role, making it slightly vague but not misleading.

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 description provides no guidance on when to use this tool versus alternatives like apply_color or list_color_swatches. There is no mention of prerequisites, typical use cases, or situations where this tool should not be used.

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