+## Customizing the sandbox environment (Docker/Podman)
+
+### Currently, the project does not support the use of the BUILD_SANDBOX function after installation through the npm package
+
+1. To build a custom sandbox, you need to access the build scripts (scripts/build_sandbox.js) in the source code repository.
+2. These build scripts are not included in the packages released by npm.
+3. The code contains hard-coded path checks that explicitly reject build requests from non-source code environments.
+
+If you need extra tools inside the container (e.g., `git`, `python`, `rg`), create a custom Dockerfile, The specific operation is as follows
+
+#### 1、Clone qwen code project first, https://github.com/QwenLM/qwen-code.git
+
+#### 2、Make sure you perform the following operation in the source code repository directory
+
+```bash
+# 1. First, install the dependencies of the project
+npm install
+
+# 2. Build the Qwen Code project
+npm run build
+
+# 3. Verify that the dist directory has been generated
+ls -la packages/cli/dist/
+
+# 4. Create a global link in the CLI package directory
+cd packages/cli
+npm link
+
+# 5. Verification link (it should now point to the source code)
+which qwen
+# Expected output: /xxx/xxx/.nvm/versions/node/v24.11.1/bin/qwen
+# Or similar paths, but it should be a symbolic link
+
+# 6. For details of the symbolic link, you can see the specific source code path
+ls -la $(dirname $(which qwen))/../lib/node_modules/@qwen-code/qwen-code
+# It should show that this is a symbolic link pointing to your source code directory
+
+# 7.Test the version of qwen
+qwen -v
+# npm link will overwrite the global qwen. To avoid being unable to distinguish the same version number, you can uninstall the global CLI first
+```
+
+#### 3、Create your sandbox Dockerfile under the root directory of your own project
+
+- Path: `.qwen/sandbox.Dockerfile`
+
+- Official mirror image address:https://github.com/QwenLM/qwen-code/pkgs/container/qwen-code
+
+```bash
+# Based on the official Qwen sandbox image (It is recommended to explicitly specify the version)
+FROM ghcr.io/qwenlm/qwen-code:sha-570ec43
+# Add your extra tools here
+RUN apt-get update && apt-get install -y \
+    git \
+    python3 \
+    ripgrep
+```
+
+#### 4、Create the first sandbox image under the root directory of your project
+
+```bash
+GEMINI_SANDBOX=docker BUILD_SANDBOX=1 qwen -s
+# Observe whether the sandbox version of the tool you launched is consistent with the version of your custom image. If they are consistent, the startup will be successful
+```
+
+This builds a project-specific image based on the default sandbox image.
+
+#### Remove npm link
+
+- If you want to restore the official CLI of qwen, please remove the npm link
+
+```bash
+# Method 1: Unlink globally
+npm unlink -g @qwen-code/qwen-code
+
+# Method 2: Remove it in the packages/cli directory
+cd packages/cli
+npm unlink
+
+# Verification has been lifted
+which qwen
+# It should display "qwen not found"
+
+# Reinstall the global version if necessary
+npm install -g @qwen-code/qwen-code
+
+# Verification Recovery
+which qwen
+qwen --version
+```

+- **Error: `UNABLE_TO_GET_ISSUER_CERT_LOCALLY`, `UNABLE_TO_VERIFY_LEAF_SIGNATURE`, or `unable to get local issuer certificate`**
   - **Cause:** You may be on a corporate network with a firewall that intercepts and inspects SSL/TLS traffic. This often requires a custom root CA certificate to be trusted by Node.js.
   - **Solution:** Set the `NODE_EXTRA_CA_CERTS` environment variable to the absolute path of your corporate root CA certificate file.
     - Example: `export NODE_EXTRA_CA_CERTS=/path/to/your/corporate-ca.crt`

+  - **Cause:** Node.js could not reach Qwen OAuth endpoints (often a proxy or SSL/TLS trust issue). When available, Qwen Code will also print the underlying error cause (for example: `UNABLE_TO_VERIFY_LEAF_SIGNATURE`).
+  - **Solution:**
+    - Confirm you can access `https://chat.qwen.ai` from the same machine/network.
+    - If you are behind a proxy, set it via `qwen --proxy <url>` (or the `proxy` setting in `settings.json`).
+    - If your network uses a corporate TLS inspection CA, set `NODE_EXTRA_CA_CERTS` as described above.
+
 - **Issue: Unable to display UI after authentication failure**
   - **Cause:** If authentication fails after selecting an authentication type, the `security.auth.selectedType` setting may be persisted in `settings.json`. On restart, the CLI may get stuck trying to authenticate with the failed auth type and fail to display the UI.
   - **Solution:** Clear the `security.auth.selectedType` configuration item in your `settings.json` file:

+**Usage notes**:
+- The command argument is required.
+- You can specify an optional timeout in milliseconds (up to 600000ms / 10 minutes). If not specified, commands will timeout after 120000ms (2 minutes).
+- It is very helpful if you write a clear, concise description of what this command does in 5-10 words.
+
+- Avoid using run_shell_command with the \`find\`, \`grep\`, \`cat\`, \`head\`, \`tail\`, \`sed\`, \`awk\`, or \`echo\` commands, unless explicitly instructed or when these commands are truly necessary for the task. Instead, always prefer using the dedicated tools for these commands:
+  - File search: Use glob (NOT find or ls)
+  - Content search: Use grep_search (NOT grep or rg)
+  - Read files: Use read_file (NOT cat/head/tail)
+  - Edit files: Use edit (NOT sed/awk)
+  - Write files: Use write_file (NOT echo >/cat <<EOF)
+  - Communication: Output text directly (NOT echo/printf)
+- When issuing multiple commands:
+  - If the commands are independent and can run in parallel, make multiple run_shell_command tool calls in a single message. For example, if you need to run "git status" and "git diff", send a single message with two run_shell_command tool calls in parallel.
+  - If the commands depend on each other and must run sequentially, use a single run_shell_command call with '&&' to chain them together (e.g., \`git add . && git commit -m "message" && git push\`). For instance, if one operation must complete before another starts (like mkdir before cp, Write before run_shell_command for git operations, or git add before git commit), run these operations sequentially instead.
+  - Use ';' only when you need to run commands sequentially but don't care if earlier commands fail
+  - DO NOT use newlines to separate commands (newlines are ok in quoted strings)
+- Try to maintain your current working directory throughout the session by using absolute paths and avoiding usage of \`cd\`. You may use \`cd\` if the User explicitly requests it.

-      - Any command expected to run indefinitely until manually stopped
-      
-      **Use foreground execution (is_background: false) for:**
-      - One-time commands: \`ls\`, \`cat\`, \`grep\`
-      - Build commands: \`npm run build\`, \`make\`
-      - Installation commands: \`npm install\`, \`pip install\`
-      - Git operations: \`git commit\`, \`git push\`

+**Usage notes**:
+- The command argument is required.
+- You can specify an optional timeout in milliseconds (up to 600000ms / 10 minutes). If not specified, commands will timeout after 120000ms (2 minutes).
+- It is very helpful if you write a clear, concise description of what this command does in 5-10 words.
+
+- Avoid using run_shell_command with the \`find\`, \`grep\`, \`cat\`, \`head\`, \`tail\`, \`sed\`, \`awk\`, or \`echo\` commands, unless explicitly instructed or when these commands are truly necessary for the task. Instead, always prefer using the dedicated tools for these commands:
+  - File search: Use ${ToolNames.GLOB} (NOT find or ls)
+  - Content search: Use ${ToolNames.GREP} (NOT grep or rg)
+  - Read files: Use ${ToolNames.READ_FILE} (NOT cat/head/tail)
+  - Edit files: Use ${ToolNames.EDIT} (NOT sed/awk)
+  - Write files: Use ${ToolNames.WRITE_FILE} (NOT echo >/cat <<EOF)
+  - Communication: Output text directly (NOT echo/printf)
+- When issuing multiple commands:
+  - If the commands are independent and can run in parallel, make multiple run_shell_command tool calls in a single message. For example, if you need to run "git status" and "git diff", send a single message with two run_shell_command tool calls in parallel.
+  - If the commands depend on each other and must run sequentially, use a single run_shell_command call with '&&' to chain them together (e.g., \`git add . && git commit -m "message" && git push\`). For instance, if one operation must complete before another starts (like mkdir before cp, Write before run_shell_command for git operations, or git add before git commit), run these operations sequentially instead.
+  - Use ';' only when you need to run commands sequentially but don't care if earlier commands fail
+  - DO NOT use newlines to separate commands (newlines are ok in quoted strings)
+- Try to maintain your current working directory throughout the session by using absolute paths and avoiding usage of \`cd\`. You may use \`cd\` if the User explicitly requests it.
