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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explains what the tool returns (differences in props, import path, source code), but it does not disclose whether the operation is read-only, any side effects, authorization requirements, or performance implications. The description gives moderate transparency but lacks depth.

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 concise and to the point. It uses active voice and front-loads the core action. There is no redundant information, and every word contributes to the meaning.

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 no output schema, the description explains the return value adequately by listing what differences are shown (props, import path, source code). It covers the essential information for a comparison tool. However, it could be slightly more comprehensive by including an example or note about the optional libraries parameter.

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%, with both parameters having descriptions in the schema. The description adds no new meaning beyond the schema; it uses the same terms. The baseline score of 3 is appropriate since the schema already adequately documents the parameters.

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 purpose: comparing the same component across two or more libraries. It specifies the aspects compared (props, import path, source code), distinguishing it from sibling tools like get_component (which presumably fetches a single component) and search_component (which searches for components). The verb 'compare' and resource 'components' are specific and unambiguous.

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 the tool should be used when one needs to compare a component across different libraries, but it does not explicitly state when to use it vs. alternatives. No exclusions or prerequisites are mentioned. With sibling tools like get_component and search_component, the usage context is somewhat clear but not articulated.

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