list_components

Browse all React upload components by category to find the right variant for drag-and-drop, progress indicators, or gallery layouts. Returns a JSON list with names, descriptions, and design inspiration.

Instructions

List every React upload component shipped by @uploadkitdev/react with its name, category, one-line description, and design inspiration.

When to use: before recommending or scaffolding any UploadKit component, to confirm the exact name exists and to pick the right variant for the user's context (e.g. browse all "dropzone" variants when the user wants a drag-and-drop area).

Returns: JSON { count, components: [{ name, category, description, inspiration }] }. Read-only, no side effects, idempotent.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
categoryNoOptional filter. Narrows the list to one category. Omit to get every component. Values: "classic" (the original 5 primitives like UploadButton/UploadDropzone), "dropzone" (styled drag-and-drop variants), "button" (styled button variants with motion), "progress" (upload progress indicators), "motion" (motion-forward visualizations like data streams, particles), "specialty" (avatars, chat composers, wizards, envelopes), "gallery" (multi-file layouts like grid, timeline, kanban).

TDQS

A4.5/5.0
Behavior5/5

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

With no annotations provided, the description carries the full transparency burden. It explicitly states 'Read-only, no side effects, idempotent' and also describes the return JSON structure, covering behavior and impact thoroughly.

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 three sentences: purpose, when-to-use, and return/behavior. It is front-loaded with the main action, every sentence has a distinct role, and there is no fluff or redundancy.

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

Completeness5/5

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

Despite lacking an output schema, the description explicitly states the return format. For a simple one-parameter list operation, it covers purpose, use context, side-effect profile, and return structure—fully sufficient for an agent to select and invoke correctly.

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?

The input schema provides 100% coverage with a detailed enum description for the optional category parameter. The description adds little beyond the schema (only a passing example of 'dropzone' variants), so it neither enhances nor detracts from the schema-provided semantics.

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 opens with a specific verb and resource: 'List every React upload component shipped by @uploadkitdev/react with its name, category, one-line description, and design inspiration.' This clearly distinguishes it from siblings like get_component (single component) and search_components (search vs. full list).

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 includes an explicit 'When to use' clause: 'before recommending or scaffolding any UploadKit component, to confirm the exact name exists and to pick the right variant.' This provides clear usage context but does not explicitly name alternatives or exclusions (e.g., when to prefer search_components).

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