cmyk_to_hex

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

No annotations are provided, so the description carries full burden. It discloses parameter ranges but fails to mention output format (e.g., hex string like #RRGGBB), error conditions, or side effects. This is incomplete for a conversion tool.

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 concise with a single sentence and parameter list. However, it omits output details, which would be valuable. Still, it avoids unnecessary verbiage.

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?

An output schema exists but is not shown; the description does not explain return values. For a simple conversion tool, this is adequate but incomplete. Could mention the output type (e.g., hex color string).

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 no descriptions (0% coverage), so the description compensates by providing clear parameter descriptions and value ranges for all four parameters. This adds meaningful semantics.

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 converts CMYK to hex color, which is a specific verb+resource. It distinguishes from siblings like hex_to_cmyk, hex_to_hsl, etc., but does not explicitly differentiate from the reverse conversion.

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?

Parameter ranges are given (0-100), implying correct input values. No explicit guidance on when to use this tool vs alternatives, nor exclusions. Usage context is implied but not elaborated.

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