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

Discloses that the tool is free and runs entirely within Claude Code. Mentions capturing a screenshot and returning it with a design review. However, it does not detail whether the tool modifies state, requires user input after capture, or the exact nature of the return behavior. The description mixes instructions to the user with tool behavior.

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?

Description is concise with three sentences. The first sentence clearly states purpose. The subsequent sentences add context and usage guidance, though the instruction about analyzing the screenshot could be considered redundant or user guidance rather than tool description.

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 simplicity (one parameter, no output schema, no annotations), the description adequately covers purpose, exclusions, and usage context (rapid design iteration). It lacks information about error conditions or return format, but these are minimal concerns for this tool.

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% for the single parameter, so the schema already provides a clear description. The description adds no additional parameter semantics beyond 'captures a screenshot' which is implicit from the tool's purpose.

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?

Clearly states it is a 'design-only review' that captures a screenshot and provides visual/UX feedback. Explicitly distinguishes from siblings by stating 'No code analysis, no performance audit — just visual/UX feedback.' The verb+resource is specific and the scope is well-defined.

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?

States it is 'Great for rapid design iteration' and excludes code/performance analysis, implying when to use. However, it does not explicitly name alternatives or provide exclusion criteria beyond the implicit contrast with non-design tools.

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