antd

name	antd
description	Use when the user's task involves Ant Design (antd) — writing antd components, debugging antd issues, querying antd APIs/props/tokens/demos, migrating between antd versions, or analyzing antd usage in a project. Triggers on antd-related code, imports from 'antd', or explicit antd questions.

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:

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.

# 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):

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., v4 → v5):

# 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:

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

# 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. 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:

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:

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.

11. 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 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 — First run antd env to capture the full environment, then use antd bug to report. Always preview first, get user confirmation, then submit.
7. Auto-report CLI issues — If any antd command crashes, returns wrong data, or behaves inconsistently, proactively use antd bug-cli to report it. You are the quality feedback loop for the CLI — don't silently work around issues.
