color_info

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

The description implies a read-only lookup, but with no annotations, it does not explicitly state that no modifications occur. It also fails to disclose behavior for invalid inputs or the effect of the format parameter.

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, which is concise, but it lacks detail on parameters and output, making it under-informative for effective tool selection.

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 no output schema and minimal schema descriptions, the description is incomplete. It does not specify return fields, accepted color formats, or error handling, which is insufficient for an agent.

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?

With 0% schema coverage, the description should explain parameter meanings. It only mentions the overall action, not what 'color' (e.g., hex, name) or 'format' (e.g., json, text) accept, leaving the agent guessing.

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 'Get information about a color (name, complementary, etc.)', specifying the verb 'get' and resource 'color information'. It distinguishes from sibling tools like color_contrast_ratio, color_convert, color_mix, and color_palette, which have different purposes.

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 usage guidance provided. The description does not indicate when to use this tool versus alternatives, nor does it mention prerequisites or limitations.

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