color_darkmode

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

No annotations provided. Description uses vague term 'intelligently' without explaining mapping logic, preservation rules, or side effects. Does not disclose behavior beyond a high-level claim.

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?

Single sentence, front-loaded with key action. Efficient but omits behavioral details that could be included concisely.

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?

Minimal description for a 2-param tool with no output schema. Missing details on color mapping strategy, handling of nested frames, and limitations.

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 100%: nodeId and brandColor are described in schema. Description adds no extra meaning beyond what's already in schema fields.

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?

Clear verb ('generate') and resource ('dark mode variant of a frame'). Distinguishes from sibling tools like 'color_lightmode' which does the opposite.

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 explicit when-to-use or when-not-to-use. Implied use for creating dark mode, but lacks alternatives among many sibling color tools.

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