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

No annotations are present, so the description carries the burden of behavioral disclosure. The verb 'Get' signals a read-only, non-destructive operation, but the description does not detail return format, side effects, format-specific behavior, or any limitations. It adds the developer-handoff context but little else.

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 with a front-loaded verb, no filler, and a useful parenthetical context. Every word earns its place.

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?

The tool is simple and the schema is complete, but the description leaves the return value ambiguous and does not clarify how it relates to overlapping siblings like copy_css or export_design_specs. It is adequate for a basic call but not fully complete for agent decision-making.

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%: both nodeId and format are described in the schema, including the format enum and default. The description adds no additional parameter meaning beyond what the schema already provides, so the baseline score of 3 applies.

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 states a specific verb ('Get') and a clear resource ('CSS representation of a node'), with the parenthetical 'for developer handoff' adding intent. However, it does not explicitly differentiate the tool from overlapping siblings such as copy_css or export_design_specs.

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 provided on when to use this tool versus alternatives. There are no exclusions, prerequisites, or comparisons; the only contextual hint is 'for developer handoff', which implies a use case but does not help an agent choose among similar CSS/export tools.

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