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

Annotations already declare readOnlyHint=true and idempotentHint=true, covering safety and side-effect concerns. The description adds that it returns a paginated list, which is useful, but it does not elaborate on pagination behavior or result content beyond that. It adds some value but does not go far beyond the structured annotations.

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 one sentence, front-loaded with the verb 'search' and the resource, and wastes no words. Every part is relevant and it remains fully readable.

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 10 parameters and no output schema, the description is on the minimal side. It notes pagination but does not explain how filters combine (e.g., AND vs OR), what fields appear in the result list, or default sorting. Schema covers parameter descriptions, so the agent can infer, but the description could compensate more for the absent output schema.

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 100%, so all parameters are already documented meaningfully. The description merely lists the same search dimensions without adding extra syntax, combination logic, or defaults. It provides no additional value beyond 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 searches the color-palette catalog by specific criteria (name, tone, temperature, mood, harmony, color count, tags). This distinguishes it from sibling tools like search_fonts (searching fonts) and get_palette (fetching a specific palette).

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 use for finding palettes by various attributes but does not explicitly mention when to prefer this over alternatives or provide exclusions. The purpose is clear enough for an agent to infer usage, but it lacks direct guidance such as 'Use for discovery, use get_palette for a known ID.'

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