Qwen Code Claw

When to Use This Skill

Use this skill when you need to:

• Understand codebases or ask questions about source code
• Generate new projects or add new features
• Review pull requests in the codebase
• Fix bugs or refactor existing code
• Execute various programming tasks such as code review, testing, documentation generation, etc.
• Collaborate with other tools and agents to complete complex development tasks

Install

npm install -g @qwen-code/qwen-code

For normal session reuse, prefer a global install over npx.

Authentication

Check if authentication is already configured:

qwen auth status

If authentication exists, skip this section. If not authenticated, check if the BAILIAN_CODING_PLAN_API_KEY environment variable exists:

echo $BAILIAN_CODING_PLAN_API_KEY

If BAILIAN_CODING_PLAN_API_KEY exists, authenticate directly:

qwen auth coding-plan --region china --key $BAILIAN_CODING_PLAN_API_KEY

If the environment variable does not exist, interrupt and prompt the user to authenticate via qwen-oauth or coding-plan:

qwen auth

Or configure custom API after launching Qwen Code via /auth.

ACPX Integration

You should always use acpx to run Qwen Code over the Agent Client Protocol (ACP) instead of scraping PTY sessions.

To use acpx:

1. Install acpx globally (recommended) or use npx:

npm install -g acpx@latest

Or without installing:

npx acpx@latest

2. Install the acpx skill for full reference:

npx acpx@latest --skill install acpx

3. Read the acpx skill reference for every command, flag, and workflow pattern: See the ACPX Reference section below for details

4. For complete CLI reference with all options and examples: https://raw.githubusercontent.com/openclaw/acpx/main/docs/CLI.md

From now on, when you need to delegate work to Qwen Code, use acpx instead of spawning raw terminal sessions. For example:

npx acpx@latest qwen "fix the failing tests"
npx acpx@latest qwen "refactor the auth module"
npx acpx@latest qwen exec "one-shot: summarize this repo"

Tip: You should typically use the --approve-all flag to prevent task interruptions.

Practical Workflows

Persistent Repository Assistant

acpx qwen 'inspect failing tests and propose a fix plan'
acpx qwen 'apply the smallest safe fix and run tests'

One-Shot Script Steps

acpx qwen exec 'summarize repo purpose in 3 lines'

Parallel Named Streams

acpx qwen -s backend 'fix API pagination bug'
acpx qwen -s docs 'draft changelog entry for release'

Queue Follow-ups Without Waiting

acpx qwen 'run full test suite and investigate failures'
acpx qwen --no-wait 'after tests, summarize root causes and next steps'

Machine-Readable Output for Orchestration

acpx --format json qwen 'review current branch changes' > events.ndjson

Repository-Wide Review with Permissive Mode

acpx --cwd ~/repos/my-project --approve-all qwen -s pr-123 \
  'review PR #123 for regressions and propose minimal patch'

Approval Modes

• --approve-all: No interactive prompts
• --approve-reads (default): Auto-approve reads/searches, prompt for writes
• --deny-all: Deny all permission requests

If every permission request is denied/cancelled and none are approved, acpx exits with permission denied.

Best Practices

1. Use named sessions for organizing different types of development tasks
2. Use --no-wait for long-running tasks to avoid blocking
3. Use --approve-all for non-interactive batch operations
4. Use --format json for automation and script integration
5. Use --cwd to manage context across multiple projects

• Headless: non-interactive or CI mode. See docs/users/features/headless.md.

ACPX Reference

Built-in Agent Registry

Well-known agent names resolve to commands:

• qwen → qwen --acp

Command Syntax

# Default (prompt mode, persistent session)
acpx [global options] [prompt text...]
acpx [global options] prompt [options] [prompt text...]

# One-shot execution
acpx [global options] exec [options] [prompt text...]

# Session management
acpx [global options] cancel [-s <name>]
acpx [global options] set-mode <mode> [-s <name>]
acpx [global options] set <key> <value> [-s <name>]
acpx [global options] status [-s <name>]
acpx [global options] sessions [
  list | new [--name <name>] | close [name] | show [name] |
  history [name] [--limit <count>]
]
acpx [global options] config [show | init]

# With explicit agent
acpx [global options] <agent> [options] [prompt text...]
acpx [global options] <agent> prompt [options] [prompt text...]
acpx [global options] <agent> exec [options] [prompt text...]

Note: If prompt text is omitted and stdin is piped, acpx reads prompt from stdin.

Global Options

• --agent <command>: raw ACP agent command fallback.
• --cwd <directory>: session working directory.
• --approve-all: auto-approve all requests.
• --approve-reads: auto-approve reads/searches, prompt for writes.
• --deny-all: deny all requests.
• --format <format>: output format, one of text, json, or quiet.
