antd

What this skill does

# Ant Design CLI

You have access to `@ant-design/cli` — a local CLI tool with bundled antd metadata for v4/v5/v6. Use it to query component knowledge, analyze projects, and guide migrations. All data is offline, no network needed.

## Setup

Before first use, check if the CLI is installed. If not, install it automatically:

```bash
which antd || npm install -g @ant-design/cli
```

After running any command, if the output contains an "Update available" notice, run `npm install -g @ant-design/cli` to update before continuing.

**Always use `--format json` for structured output you can parse programmatically.**

## Scenarios

### 1. Writing antd component code

Before writing any antd component code, look up its API first — don't rely on memory.

```bash
# Check what props are available
antd info Button --format json

# Get a working demo as starting point
antd demo Button basic --format json

# Check semantic classNames/styles for custom styling
antd semantic Button --format json

# Check component-level design tokens for theming
antd token Button --format json
```

**Workflow:** `antd info` → understand props → `antd demo` → grab a working example → write code.

### 2. Looking up full documentation

When you need comprehensive component docs (not just props):

```bash
antd doc Table --format json        # full markdown docs for Table
antd doc Table --lang zh            # Chinese docs
```

### 3. Debugging antd issues

When code isn't working as expected or the user reports an antd bug:

```bash
# Check if the prop exists for the user's antd version
antd info Select --version 5.12.0 --format json

# Check if the prop is deprecated
antd lint ./src/components/MyForm.tsx --format json

# Diagnose project-level configuration issues
antd doctor --format json
```

**Workflow:** `antd doctor` → check environment → `antd info --version X` → verify API against the user's exact version → `antd lint` → find deprecated or incorrect usage.

### 4. Migrating between versions

When the user wants to upgrade antd (e.g., v4 → v5):

```bash
# Get full migration checklist
antd migrate 4 5 --format json

# Check migration for a specific component
antd migrate 4 5 --component Select --format json

# See what changed between two versions
antd changelog 4.24.0 5.0.0 --format json

# See changes for a specific component
antd changelog 4.24.0 5.0.0 Select --format json
```

**Workflow:** `antd migrate` → get full checklist → `antd changelog <v1> <v2>` → understand breaking changes → apply fixes → `antd lint` → verify no deprecated usage remains.

### 5. Analyzing project antd usage

When the user wants to understand how antd is used in their project:

```bash
# Scan component usage statistics
antd usage ./src --format json

# Filter to a specific component
antd usage ./src --filter Form --format json

# Lint for best practice violations
antd lint ./src --format json

# Check only specific rule categories
antd lint ./src --only deprecated --format json
antd lint ./src --only a11y --format json
antd lint ./src --only performance --format json
```

### 6. Checking changelogs and version history

When the user asks about what changed in a version:

```bash
# Specific version changelog
antd changelog 5.22.0 --format json

# Version range (both ends inclusive)
antd changelog 5.21.0..5.24.0 --format json
```

### 7. Exploring available components

When the user is choosing which component to use:

```bash
# List all components with categories
antd list --format json

# List components for a specific antd version
antd list --version 5.0.0 --format json
```

### 8. Reporting antd bugs

When you encounter a confirmed antd component bug that can't be resolved locally:

```bash
# Step 1: Preview for user review
antd bug --title "DatePicker crashes when selecting date" \
  --reproduction "https://codesandbox.io/s/xxx" \
  --steps "1. Open DatePicker 2. Click a date" \
  --expected "Date is selected" \
  --actual "Component crashes with error" \
  --format json

# Step 2: Show to user, ask for confirmation

# Step 3: Submit after user confirms
antd bug --title "DatePicker crashes when selecting date" \
  --reproduction "https://codesandbox.io/s/xxx" \
  --steps "1. Open DatePicker 2. Click a date" \
  --expected "Date is selected" \
  --actual "Component crashes with error" \
  --submit
```

### 9. Auto-reporting CLI issues

**IMPORTANT: Whenever you use any `antd` CLI command and notice something wrong, you should proactively initiate a bug report using `antd bug-cli`.**

Trigger conditions — report a CLI bug when you observe any of these:
- A command **crashes or exits with an unexpected error**
- A command **returns clearly incorrect data** (e.g. `antd info Button` shows wrong props, missing props, or props from the wrong version)
- A command's **output doesn't match its documented behavior** (e.g. `--format json` returns non-JSON, `--version X` is ignored)
- A command **returns empty or missing data** when it shouldn't (e.g. `antd demo Button` returns no demos, `antd token Button` returns no tokens for v5+)
- **Inconsistencies between commands** (e.g. `antd list` shows a component but `antd info` says it doesn't exist)

**Workflow:**
1. You notice something wrong while using the CLI
2. Gather evidence: the exact command you ran, what was returned, and what you expected
3. Preview the bug report for the user:

```bash
antd bug-cli --title "antd info Button returns wrong props for v5.12.0" \
  --description "When querying Button props for version 5.12.0, the output includes props that don't exist in that version" \
  --steps "1. Run: antd info Button --version 5.12.0 --format json" \
  --expected "Props matching antd 5.12.0 Button API" \
  --actual "Props include 'classNames' which was added in 5.16.0" \
  --format json
```

4. Show the report to the user: "I noticed an issue with the CLI while working. Here's a bug report — shall I submit it?"
5. Submit after user confirms:

```bash
antd bug-cli --title "antd info Button returns wrong props for v5.12.0" \
  --description "..." \
  --steps "..." \
  --expected "..." \
  --actual "..." \
  --submit
```

**Key principle:** You are a quality feedback loop for the CLI. Don't silently work around CLI issues — report them so they get fixed. Always confirm with the user before submitting.

### 10. Using as MCP server

If working in an IDE that supports MCP (Claude Desktop, Cursor, etc.), the CLI can also run as an MCP server, exposing all knowledge-query tools directly:

```json
{
  "mcpServers": {
    "antd": {
      "command": "antd",
      "args": ["mcp", "--version", "5.20.0"]
    }
  }
}
```

This provides 7 tools (`antd_list`, `antd_info`, `antd_doc`, `antd_demo`, `antd_token`, `antd_semantic`, `antd_changelog`) and 2 prompts (`antd-expert`, `antd-page-generator`) via MCP protocol.

## Global Flags

| Flag | Purpose |
|---|---|
| `--format json` | Structured output — always use this |
| `--version <v>` | Target a specific antd version (e.g. `5.20.0`) |
| `--lang zh` | Chinese output (default: `en`) |
| `--detail` | Include extra fields (description, since, deprecated, FAQ) |

## Key Rules

1. **Always query before writing** — Don't guess antd APIs from memory. Run `antd info` first.
2. **Match the user's version** — If the project uses antd 4.x, pass `--version 4.24.0`. The CLI auto-detects from `node_modules` if no flag is given.
3. **Use `--format json`** — Every command supports it. Parse the JSON output rather than regex-matching text output.
4. **Check before suggesting migration** — Run `antd changelog <v1> <v2>` and `antd migrate` before advising on version upgrades.
5. **Lint after changes** — After writing or modifying antd code, run `antd lint` on the changed files to catch deprecated or problematic usage.
6. **Report antd bugs** — When you encounter an antd component bug, use `antd bug` to report it. Always preview first, get user confirmation, then submit.
7. **Auto-report CLI issues** — If any `antd` command crashes, retur
