generate_color_palette

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

The description implies a pure generation function without side effects, but with no annotations, it could add more detail on safety, idempotency, or output format. It is adequate but not explicit about behavior beyond return values.

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 two sentences, no unnecessary words, and is front-loaded with the main purpose. Every sentence adds value.

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 the tool has 3 parameters all described, and no output schema, the description covers the main output types and compliance. It is nearly complete, though could specify that output is in hex format.

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%, and the description adds no new meaning beyond what is in the schema. The parameters are fully described in the schema, so the description provides no additional value for parameter understanding.

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 verb 'Generate' and the resource 'accessible color palette from a base color', specifying output categories (primary, secondary, neutral, semantic) with WCAG compliance. This distinguishes it from sibling tools like analyze_accessibility or check_contrast.

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 is given on when to use this tool versus alternatives. For example, it doesn't mention that for checking contrast ratios, the user should use check_contrast instead.

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