list_classes

Discover available semantic CSS class names by category. Filter by buttons, cards, forms, and more to find the right pattern.

Instructions

List all available semantic class names, optionally filtered by category. Use this to discover available patterns.

Behavior3/5

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

No annotations are provided, so the description must fully convey behavioral traits. It indicates a read operation (list) but does not detail side effects, authentication needs, or output format. Given the lack of annotations, the description is adequate but not exhaustive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with the action ('List all available semantic class names'), and no wasted words. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 2 optional parameters and no output schema, the description covers the purpose and usage hint. It could benefit from specifying the output format (e.g., just names or objects), but it is mostly complete for a simple listing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the input schema already documents parameters well. The description merely echoes the optional filter capability without adding new semantic meaning beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool lists all available semantic class names, optionally filtered by category. This distinguishes it from siblings like 'search_classes' (searching) and 'get_class' (single class details), providing a specific verb and resource.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description suggests using the tool to 'discover available patterns,' giving a clear usage context. However, it does not explicitly mention when not to use it (e.g., for detailed info on a single class, use 'get_class'), leaving some ambiguity against siblings.

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