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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It only restates the core action without explaining side effects, whether the operation is read-only, if it makes external calls, or what the output structure will look like. This is a significant gap for a generation 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 a single sentence that is front-loaded with the key action and resource. Every word is necessary, and there is no filler or redundancy. This is an ideal level of conciseness.

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 tool with 4 parameters, no output schema, and no annotations, the description is too sparse. It leaves unanswered questions about what 'complete' means, how the format parameter affects output, and how contrastLevel influences the palette. The schema provides enums but not enough behavioral context.

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 description coverage is only 25% (only contrastLevel is documented). The description adds meaning for baseColor ('single base color') but says nothing about mode, format, or contrastLevel. With such low schema coverage, the description should compensate more but does not.

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: generating a complete Material 3 color palette from a single base color. The verb 'generate' is specific, and the resource is well-defined. It naturally distinguishes itself from sibling tools that deal with components, icons, or design tokens.

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 usage context is implied but not explicit. It suggests using the tool when you have a base color and want a Material 3 palette, but it does not mention when not to use it or explicitly name alternatives. This is a clear context with no exclusions, so it falls between 'implied usage' and 'clear context'.

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