hex_to_hsl

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

No annotations provided. The description only states the conversion purpose and parameter. It does not disclose edge cases, invalid input handling, or color space assumptions.

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 extremely concise—two sentences covering purpose and parameter. No fluff, front-loaded.

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?

For a simple conversion tool, the description covers the essential input format. The output schema (present) likely handles the return structure. Minor omission: no explicit output description.

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 schema has 0% description coverage, but the description adds crucial format guidance: 'Hex color without # (e.g. '3498db')'. This compensates well for the schema gap.

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 'Convert hex color to HSL values', specifying the verb and resource. It is distinct from sibling tools like hex_to_cmyk or hex_to_hsv, but lacks explicit output format details.

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 on when to use this tool versus other color conversion tools (e.g., hex_to_hsv, hsl_to_rgb). No context on prerequisites or exclusions.

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