## What it does

Activated via `/forms`, this skill structures input flows and web forms. It groups related inputs, places clear labels directly above fields, and scales field widths to match data formats. For flows exceeding 6–8 fields, it structures multi-step layouts with progress indicators and navigation that preserves entered draft data.

Validation adheres to strict timing. The skill applies blur checks to completed fields, keeps submit-level validation for cross-field dependencies, and prohibits showing errors on pristine fields. Error messages require `aria-invalid` associations right beneath the target input. On mobile viewports, touch targets must measure at least 44×44px alongside dedicated input types for numeric or email keyboards.

Before drafting UI code, the skill insists on loading `$frontend-design` and following its Context Gathering Protocol. Skipping that setup leaves the assistant without defined product goals and design constraints.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aladicf/better-web-ui --skill forms -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/forms/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/forms/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aladicf/better-web-ui --skill forms -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/forms/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aladicf/better-web-ui --skill forms -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/forms/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aladicf/better-web-ui forms
```

2. **Manually: put the files in place**
- File: `.github/skills/forms/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aladicf/better-web-ui --skill forms -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aladicf/better-web-ui --path skills/forms
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/forms/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aladicf/better-web-ui --skill forms -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/aladicf/better-web-ui/tree/HEAD/skills/forms/SKILL.md

## When to use it
- break complex input flows into multi-step forms that preserve user progress
- structure validation timing so pristine inputs never trigger premature errors
- optimize form inputs and virtual keyboards for handheld devices
- implement accessible form markup using ARIA attributes and explicit field associations

## Example prompts
- /forms design a 3-step checkout flow with shipping and billing validation
- /forms review our registration form layout and configure blur validation
- /forms streamline the user profile view by removing unnecessary mandatory fields

Build forms that users complete without confusion, anxiety, or abandonment. The goal is not to collect every possible field; it is to remove every unnecessary obstacle between the user and their goal.

Consult the [form validation patterns](../frontend-design/reference/form-validation-patterns.md) reference for validation timing, error placement, multi-field dependencies, async validation, and recovery design.
Consult the [live validation UX](../frontend-design/reference/live-validation-ux.md) reference for blur-vs-real-time timing, reward-early/punish-late behavior, and copy-paste-friendly validation.
Consult the [error recovery](../frontend-design/reference/error-recovery.md) reference for what happens after validation or submission fails.
Consult the [disabled buttons UX](../frontend-design/reference/disabled-buttons-ux.md) reference when deciding whether to block submit buttons or keep them enabled with error explanation.
Consult the [component anatomy](../frontend-design/reference/component-anatomy.md) reference for button, input, checkbox, radio, toggle, dropdown, and textarea anatomy guidance.

## MANDATORY PREPARATION

Users start this workflow with `/forms`. Once this skill is active, load $frontend-design — it contains design principles, anti-patterns, and the **Context Gathering Protocol**. Follow that protocol before proceeding — if no design context exists yet, you MUST load $setup first. Additionally gather: what goal the user is trying to achieve, which fields are truly required, and what causes abandonment in the current flow.

## Assess Form Needs

Understand the form's purpose and context:

1. **User goal**: What does the user get by completing this form? The clearer the payoff, the higher the completion rate.
2. **Field necessity**: Every field you add drops completion rates. Challenge each field: is it required now, or can it be collected later?
3. **Context of use**: Is the user rushed, distracted, on mobile, or in a stressful situation? Stressful contexts need simpler forms.
4. **Failure points**: Where do users currently drop off? Long forms, unclear labels, and unexpected validation are common culprits.

## Form Structure

### Field order

- Ask easy questions first to build momentum
- Group related fields visually (name fields together, address fields together)
- Place optional fields at the end or mark them clearly
- Separate billing and shipping only when they are genuinely different

### Label design

- Use clear, scannable labels above the input (not inside as placeholder text)
