What it does
Opensource UI is an agent skill from bidyut10/opensourceui. Use Opensource UI patterns and copy-paste React/Next.js components from opensourceui.in. Trigger when building or refining interfaces that need its component catalog, visual language, Tailwind conventions, mockups, widgets, forms, tables, social cards, or interactive controls.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/catalog.md`, `references/design.md` and `references/implementation.md`).
It sits in Frontend & Design, covering CSS and styling and Social media graphics. It works with Tailwind CSS, Next.js and React. The repository describes itself as: Opensource UI: Free, open-source, and production-ready components for React and Next.js. Powered by TypeScript, Tailwind CSS, and lucide icons. The licence is MIT.
When your agent uses it
- Refining interfaces that need its component catalog
- Visual language
- Tailwind conventions
- Interactive controls
Example prompts
- “/opensource-ui”
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.

What it can do on your machine
Read from SKILL.md and the folder at commit b57d5d6. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Opensource UI loads about 1.1k tokens when it runs, and up to ~17k if it reads all its reference files. Until then it costs about 73 tokens; SKILL.md has 605 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Use Opensource UI patterns and copy-paste React/Next.js components from opensourceui.in. Trigger when building or refining interfaces that need its component catalog, visual language, Tailwind conventions, mockups, widgets, forms, tables, social cards, or interactive controls.
Opensource UI
Use this skill when the user asks for an Opensource UI component, an Opensource UI-inspired interface, or a React/Next.js component selected from the Opensource UI catalog.
Works with any coding agent (Cursor, Claude Code, Codex, Copilot, Grok, etc.). Read the reference files in this skill folder before generating UI.
Core workflow
- Identify the requested UI role, such as button, input, calendar, widget, mockup, notification, table, social card, or editorial card.
- Search
references/catalog.mdfor the closest catalog entry and route. - Read
references/design.mdfor the visual rules. Apply the neutral stage, Instrument Serif for brand display text, Geist for UI text, restrained accents, flat surfaces, and border-based focus states. - If source code is available in the attached repository or a target project, inspect the relevant component before adapting it. Preserve the component's state behavior, accessibility, and prop API unless the user requests a change.
- For a new web project, use React or Next.js with TypeScript and Tailwind CSS v4. Copy the needed component files and icon dependencies. There is no package installation step for the UI library itself.
- Copy
lib/cn.tswhen the component usescn, then install or preserveclsxandtailwind-merge. Copy imported icons from the repository'sicons/tree. Keepuse clientwhen the component uses browser state, effects, event handlers, or browser APIs. - Use base styles plus
md:responsive variants. Do not introducesm:breakpoints. Prefer native HTML semantics, keyboard support, labels, visible error text, and WCAG AA contrast. - Verify the result in the target project. Check interaction states, reduced-motion behavior, mobile layout, focus visibility, and import paths.
Design rules
Keep site chrome neutral: white or near-white surfaces, neutral borders, dark ink, and sparse cyan, rose, amber, teal, or emerald accents inside demos and state changes. Use flat surfaces by default. Avoid purple-family colors, gradients, glow, colored blur, glassmorphism, stacked card shadows, generic AI styling, and heavy dashboard chrome.
Use rounded-md for buttons, rounded-lg for fields and small cards, and rounded-2xl for larger editorial or testimonial surfaces. Use p-4 as the common internal padding. Style input focus with a darker border and ring-0, never a colored ring. Use rose for errors and required markers. Prefer forwardRef for interactive components, native HTML prop extension, and cn() for class merging.

Catalog use
The catalog contains 200+ documented components across 30 categories as listed on the site. The source repository contains the implementation files and may include additional support or showcase files. Use the category and slug in references/catalog.md to locate a component page. Use the source path in references/source_inventory.txt when working from the cloned repository.
Component pages provide a live preview, implementation details, and copy-ready source. Treat the site's source and repository as the authority for exact props and behavior. Do not invent a prop API when source is available.
Reference files
- Read
references/catalog.mdto select a component by category, name, slug, and summary. - Read
references/design.mdfor the full design system, tokens, typography, spacing, elevation, component rules, and prohibited patterns. - Read
references/implementation.mdfor repository layout, setup commands, dependency conventions, icon conventions, and copy-paste guidance. - Read
references/source_inventory.txtwhen exact repository file names or category directories are needed.
Invocation examples
Use requests such as:
- "Use the Opensource UI Booking Slot Calendar in my Next.js page."
- "Build a clean dashboard with Opensource UI tables and widgets."
- "Make this form follow the Opensource UI design language."
- "Find the closest Opensource UI component for a travel boarding pass."
When the user specifies a target project, adapt imports, aliases, Tailwind setup, and image handling to that project. When no target project exists, provide the component code and state the required files and dependencies.

To copy it by hand, put the folder in .cursor/skills/opensource-ui, .gemini/skills/opensource-ui, .github/skills/opensource-ui and .opencode/skills/opensource-ui in your project.
What does Opensource UI need to run?
SKILL.md names no scripts, command-line tools or credentials: Opensource UI is instructions for the agent only.
Does Opensource UI access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Opensource UI safe to install?

How many tokens does Opensource UI use?
About 1.1k tokens (SKILL.md is roughly 4.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 16k tokens, read only when the agent opens those files.
