List appCN components

list_components

Browse and filter appCN components by category to discover each component's slug, title, description, and signature detail. Start here to explore the registry.

Instructions

List every appCN component, optionally filtered by category. Returns each component's slug, title, category, one-line description, and its signature 'delight' detail. Start here to see what's available, then call get_component for the full source and docs.

Behavior3/5

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

With no annotations, the description carries the full burden. It implies a read-only operation by stating 'List', but does not explicitly confirm safety or disclose any behavioral traits beyond the return format. For a list tool, this is adequate but not exceptional.

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?

The description is two sentences, front-loaded with the action, and every sentence adds value: first sentence states purpose and output, second sentence gives usage context with sibling tool.

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?

Given the tool's simplicity (list with one optional filter), the description is complete in terms of purpose, output, and sibling relationship. It could mention ordering or empty results, but these are minor omissions.

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

Parameters4/5

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

Schema coverage is 100% and the schema already describes the category parameter. The description adds value by explaining the enum values ('base' for broad mobile library, 'ai' for AI-native collection), providing context beyond the schema.

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 it lists every appCN component, optionally filtered by category, and specifies the returned fields. It distinguishes from the sibling get_component by suggesting to start here and then call get_component for full details.

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 provides explicit guidance: 'Start here to see what's available, then call get_component' indicates when to use this tool and when to use an alternative. It could be more thorough about other siblings like search_components, but the guidance is clear.

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