color_harmonize

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

The description does not explain what the tool returns (e.g., a list of hex colors, the count per scheme), nor any side effects. With no annotations, the agent lacks crucial behavioral context.

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 lacks structure. It does not front-load critical details like output format or behavior.

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, the description should explain the return value (e.g., an array of color hex strings). It fails to provide this essential context, making the tool hard to use correctly.

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 100%, but the description repeats some enum values while omitting two (tetradic, monochromatic). This incomplete listing adds marginal value beyond the schema and may mislead.

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 generates harmonious colors based on a base color and lists several schemes (complementary, triadic, analogous, split-complementary). However, the enum includes additional schemes (tetradic, monochromatic) not mentioned in the description, which may cause confusion.

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 similar sibling tools like color_palette_generate or suggest_color_palette. There is no indication of prerequisites or alternatives.

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