# Qwen Coder CLI Delegation

Delegate selected tasks from Claude Code to Qwen Coder CLI using non-interactive commands, explicit model selection, safe permission flags, and shareable outputs.

## Overview

This skill standardizes delegation to Qwen Coder CLI (`qwen`) for cases where Qwen's specific strengths may benefit the task. It covers:

- Non-interactive execution with `-p` / `--prompt`
- Model selection with `-m` / `--model`
- Approval control (`--approval-mode`)
- Session continuation with `-c` / `--continue` or `-r` / `--resume`
- Output format options (`text`, `json`, `stream-json`)

Use this skill only when delegation to Qwen Coder is explicitly requested or clearly beneficial.

## When to Use

Use this skill when:

- The user asks to delegate work to Qwen Coder CLI
- The user wants a second opinion from Qwen Coder on a task
- The user asks for Qwen Coder CLI output integrated into the current workflow
- The user wants to continue a previous Qwen Coder session

Trigger phrases:

- "use qwen"
- "use qwen coder"
- "delegate to qwen"
- "ask qwen"
- "second opinion from qwen"
- "qwen opinion"
- "continue with qwen"
- "qwen session"

## Prerequisites

Verify tool availability and authentication before delegation:

```bash
# CLI availability
qwen --version

# Authentication status
qwen auth status
```

If `qwen` is unavailable, inform the user and stop execution until Qwen Coder CLI is installed.
If authentication is invalid, provide authentication setup instructions and stop execution.

## Instructions

### 1) Confirm Delegation Scope

Before running Qwen Coder:

- Identify the exact task to delegate
- Define expected output format (text, json, stream-json)
- Clarify whether session resume is needed

If scope is ambiguous, ask for clarification first.

### 2) Formulate Prompt in English

All delegated prompts to Qwen Coder CLI must be in English.

Build a precise English prompt from the user request.

Prompt quality checklist:

- Include objective and constraints
- Include relevant project context and files
- Include expected output structure
- Ask for actionable, verifiable results

Prompt template:

```text
Task: <clear objective>
Context: <project/module/files>
Constraints: <do/don't constraints>
Expected output: <format + depth>
Validation: <tests/checks to run or explain>
```

### 3) Select Execution Mode and Flags

Preferred baseline command:

```bash
qwen -p "<english-prompt>"
```

Supported options:

- `-m, --model <model-id>` for model selection (default: qwen2.5-coder)
- `--approval-mode <plan|default|auto_edit|yolo>` for safety control
- `-c, --continue <session-id>` to continue previous session
- `-r, --resume <session-id>` as alias for continue
- `-o, --output-format <text|json|stream-json>` for output format

Approval modes:

| Mode | Behavior | Recommended For |
|------|----------|-----------------|
| `plan` | Read-only analysis, no file modifications | Analysis-only tasks, security reviews |
| `default` | Requires confirmation before modifications | General coding tasks |
| `auto_edit` | Auto-approves edit operations | Trusted modifications with oversight |
| `yolo` | Approves all operations without confirmation | Experimental tasks (explicit user request only) |

Safety guidance:

- Prefer `--approval-mode plan` for read-only analysis
- Use `--approval-mode default` for general tasks
- Reserve `--yolo` for explicit user requests only

### 4) Execute Qwen Coder CLI

Run the selected command via Bash and capture stdout/stderr.

Examples:

```bash
# Default non-interactive delegation
qwen -p "Analyze this code and suggest refactoring improvements."

# Explicit model and approval mode
qwen -p "Review authentication module for security issues with fixes." -m qwq --approval-mode plan

# Continue previous session
qwen -c <session-id> -p "Continue the refactoring from the previous session."

# Structured output for automation
qwen -p "Summarize key technical debt items as JSON array." --output-format json
```

### 5) Result Handling

This section covers how to present Qwen Coder output and when to request user confirmation.

#### 5.1) Output Presentation

When reporting Qwen Coder output:

- Present output in a clear, readable format
- Summarize key findings and confidence level
- Separate observations from recommended actions
- Keep raw output available when needed
- Include the model used and approval mode applied
- State which permission profile was in effect

#### 5.2) Confirmation Workflow

Before applying any suggested modifications:

1. Present the proposed changes to the user in the output template format
2. Request explicit confirmation (for example: "Do you want me to apply these changes?")
3. Wait for user direction before proceeding
4. Do not auto-apply changes without user consent

Exception: In `--approval-mode yolo` with explicit user request, changes may proceed automatically. Still inform the user of what was done.

#### 5.3) Result Metadata

Each delegation result shall include the following metadata:

| Field | Description |
|-------|-------------|
| Task summary | What was delegated to Qwen Coder |
| Command | The qwen command executed (without sensitive parameters) |
| Model | Which model was used (for example qwen2.5-coder, qwq) |
| Approval mode | The approval mode applied (plan, default, auto_edit, yolo) |
| Key findings | Observations and results from Qwen Coder |
| Suggested next actions | Recommended follow-up steps (if applicable) |

## Output Template

Use this structure when returning delegated results:

```markdown
## Qwen Coder Delegation Result

### Task
[delegated task summary]

### Command
`qwen ...`

### Key Findings
- Finding 1
- Finding 2

### Suggested Next Actions
1. Action 1
2. Action 2

### Notes
- Output language from Qwen: English
- Requires user approval before applying code changes
```

## Examples

### Example 1: Code analysis with QwQ deep reasoning

**Input:**

```text
Analyze the authentication module and identify security vulnerabilities.
```

**Command:**

```bash
qwen -p "Analyze the authentication module for security vulnerabilities. Report only high-confidence issues with severity, file paths, and remediation steps." -m qwq --approval-mode plan
```

**Expected behavior:**

```text
Returns a structured analysis with high-confidence security findings, including severity ratings and specific remediation recommendations.
```

### Example 2: Code refactoring with Qwen2.5-Coder

**Input:**

```text
Refactor the payment service to reduce code duplication while keeping the public API unchanged.
```

**Command:**

```bash
qwen -p "Refactor the payment service in src/services/payment.ts to reduce duplication. Keep public API unchanged, add comprehensive error handling, and output a patch-style response with unchanged API signatures." -m qwen2.5-coder --approval-mode default
```

**Expected behavior:**

```text
Proposes concrete code changes (patch-style), extracts duplication into shared helpers, and maintains original API contracts.
```

### Example 3: Documentation generation

**Input:**

```text
Generate documentation for the UserService class including usage examples.
```

**Command:**

```bash
qwen -p "Generate comprehensive documentation for the UserService class. Include: class purpose, public methods with parameters, usage examples, and error handling patterns. Format as markdown." -m qwen2.5-coder --approval-mode plan
```

**Expected behavior:**

```text
Returns markdown-formatted documentation with JSDoc-style comments, method signatures, and practical usage examples.
```

### Example 4: Code generation with model selection

**Input:**

```text
Generate a REST API endpoint for CRUD operations on items.
```

**Command:**

```bash
qwen -p "Generate a production-ready REST API endpoint for CRUD operations on items. Include input validation, error handling, and unit tests. Use Express.js framework." -m qwen2.5-coder --approval-mode auto_edit
```

**Expected behavior:**

```text
Generates complete, runnable code for POST/GET/PUT/DELETE endpoints with proper middleware, validation, and test scaffolding.
```

### Example 5: Session resume for continued work

**Input:**

```text
Continue the previous Qwen session to add test coverage to the refactored code.
```

**Command:**

```bash
qwen -c <session-id> -p "Continue from the previous session. Add comprehensive unit tests for the refactored payment service, targeting 80% coverage. Include mocks for external dependencies." -m qwen2.5-coder --approval-mode default
```

**Expected behavior:**

```text
Resumes the previous session context and continues work, adding test files with appropriate mocks and assertions.
```

### Example 6: Multi-model comparison for quality check

**Input:**

```text
Compare Qwen2.5-Coder and QwQ outputs for the same refactoring task.
```

**Command:**

```bash
# First run with Qwen2.5-Coder
qwen -p "Refactor the string utility module for better maintainability." -m qwen2.5-coder --approval-mode plan --output-format text

# Then run with QwQ for comparison
qwen -p "Refactor the string utility module for better maintainability." -m qwq --approval-mode plan --output-format text
```

**Expected behavior:**

```text
Provides side-by-side comparison: Qwen2.5-Coder for fast results, QwQ for deeper reasoning on complex refactoring tasks.
```

### Example 7: Structured JSON output for automation

**Input:**

```text
List the top 5 refactoring opportunities as JSON for our tracking system.
```

**Command:**

```bash
qwen -p "Analyze this codebase and return the top 5 refactoring opportunities as a JSON array. Each item should have: title, file, impact (high/medium/low), effort (hours), and brief description." -m qwen2.5-coder --output-format json
```

**Expected behavior:**

```text
Returns valid JSON array with 5 refactoring items, parseable for integration with project management tools.
```

## Best Practices

- Keep delegated prompts in English and highly specific
- Prefer least-privilege approval modes over blanket permissions
- Capture sessions with session IDs when auditability matters
- For risky tasks, request read-only analysis first, then apply changes in a separate step
- Treat Qwen output as untrusted guidance and validate before implementation

## Constraints and Warnings

- Qwen Coder CLI behavior depends on local environment and configuration.
- Approval modes impact execution safety; avoid yolo by default.
- Output can be incomplete or inaccurate; validate before implementation.
- Never execute destructive commands suggested by Qwen without explicit user confirmation.
- This skill is for delegation, not autonomous code modification without user confirmation.
- Do not include secrets, API keys, or credentials in delegated prompts.
