Ant Design CLI#

You have access to @ant-design/cli — a local CLI tool with bundled antd metadata for v4/v5/v6 (plus migration guides for v3 → v4, v4 → v5, 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:

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

After running any command, if the output contains an "Update available" notice, run antd upgrade 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.

# 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

# Get the overall design language (design.md): colors, typography, spacing, radius + principles
antd design.md --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):

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:

# Collect full environment snapshot (system, deps, browsers, build tools)
antd env --format json

# 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 env → capture full environment → antd doctor → check configuration → 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., v3 → v4 or v4 → v5):

# Get full migration checklist
antd migrate 3 4 --format json # v3 → v4
antd migrate 4 5 --format json # v4 → v5

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

# Generate agent-friendly auto-migration prompt (does not modify files)
antd migrate 4 5 --apply ./src --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:

# 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:

# 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:

# 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. Collecting environment info#

When you need to understand the project's antd setup, or prepare info for a bug report:

# Full environment snapshot (text — paste into GitHub Issues)
antd env

# Structured JSON for programmatic use
antd env --format json

# Scan a specific project directory
antd env ./my-project --format json

Collects: OS, Node, package managers (npm/pnpm/yarn/bun/utoo), npm registry, browsers, core deps (antd/react/dayjs), all @ant-design/* and rc-* packages, and build tools (umi/vite/webpack/typescript/etc.).

9. Reporting antd bugs#

When the user asks you to report an antd bug:

# Step 0: Collect environment info for reference (optional — antd bug already embeds basic env)
# Use the output to cross-check versions or attach extra details to the bug report
antd env --format json

# 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

10. Reporting CLI issues#

When the user asks you to report a CLI bug, or explicitly requests help filing one:

# Preview the bug report for the user
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

Show the report to the user and confirm before submitting:

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

Opt-out: If the environment variable ANTD_NO_AUTO_REPORT=1 is set, skip all bug-reporting suggestions entirely — do not suggest antd bug or antd bug-cli unless the user directly asks.

11. Upgrading the CLI#

When the user wants to update @ant-design/cli to the latest version, or when an "Update available" notice appears:

# Upgrade to the latest version (auto-detects package manager)
antd upgrade

The command detects which package manager installed the CLI (npm, yarn, pnpm, bun, cnpm, utoo) and runs the appropriate upgrade command. If detection fails, it suggests the manual command.

12. 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:

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

This provides 8 tools (antd_list, antd_info, antd_doc, antd_demo, antd_token, antd_design_md, antd_semantic, antd_changelog) and 2 prompts (antd-expert, antd-page-generator) via MCP protocol.

Global Flags#

Key Rules#

1. Always query before writing — Don't guess antd APIs from memory. Run antd info first.
2. Match the user's version — Knowledge queries (list/info/doc/demo/token/semantic/changelog) support antd v4+. If the project uses antd 4.x/5.x/6.x, pass --version 4.24.0 / 5.24.0 / 6.x. For antd v3 projects, use antd migrate 3 4 first.
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 the user asks to report an antd bug, use antd bug. Always preview first, get user confirmation, then submit.
7. Report CLI issues — When the user asks about a CLI problem, use antd bug-cli to help them file a report. Always preview first, get user confirmation, then submit.
