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

With readOnlyHint=true already covering the safety profile, the description adds genuine value by disclosing the result shape (category, status, summary, exports) and the notable behavior that a non-React framework narrows results to components that actually exist in that stack. It does not mention pagination or result limits, but the core behavioral traits are covered.

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?

Three tight sentences, zero filler, with the core action and returned fields front-loaded and the framework caveat last. Every sentence carries distinct information.

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?

There is no output schema, and the description compensates by naming the returned fields, so an agent knows what it gets back. It is close to complete for a read-only list tool, with only pagination/ordering behavior left unstated.

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% and the framework enum is exhaustively documented in the schema itself, so the baseline is 3. The description restates the category/query filters and the framework restriction without adding format, default, or combination semantics beyond what the schema already provides.

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?

States a specific verb (Lists) and resource (Nasaq web components) and enumerates the returned fields (category, status, one-line summary, exports), which separates it from get_component's detail view. It does not, however, explicitly contrast itself with the close sibling search_components, so an agent must infer the boundary.

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?

Filtering behavior is implied ('Filter by category or a text query') and the framework caveat gives a real usage rule. But there is no guidance on when to prefer this over search_components or get_component, nor any stated prerequisite or exclusion.

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