color_palette

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

With no annotations, the description carries the full burden for behavioral disclosure. 'Generate color palettes' implies a non-destructive operation but gives no details about return format, side effects, or constraints. It does not disclose what a palette looks like (e.g., array of hex codes, number of colors) or any dependencies, leaving significant gaps for an agent.

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, front-loaded with the action verb and listing relevant palette types. Every word earns its place; there is no fluff or repetition. It is appropriately concise for a simple tool.

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?

With no output schema, the description should clarify what the tool returns, but it does not. The tool is low-complexity (2 params), yet an agent would not know whether the output is a list of hex codes, a count, or an object. The description is too sparse to be considered complete for safe invocation.

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 already describes the 'color' parameter well (hex or CSS name) and lists the 'type' enum. The description merely echoes some enum values ('complementary, analogous, triadic') without adding meaning beyond what the schema provides. It does not explain what each palette type produces or add any new details about parameter usage, so it adds minimal value over the schema.

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's function with a specific verb and resource: 'Generate color palettes'. It lists several palette types (complementary, analogous, triadic, split-complementary) which distinguishes it from sibling tools like check_contrast, which is about contrast checking. This makes it unambiguous what the tool does.

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?

The description implies usage for generating color palettes, providing clear context without explicit exclusions or alternatives. While no alternative is named, the purpose is specific enough that an agent would know when to choose this tool over other utility tools. It lacks a 'when not to use' note but is otherwise clear.

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