In ACP mode, the plan mode does not work as expected.

[tanzhenxin]

What happened?

In Zed editor, setup qwen with option:

    "qwen": {
      "command": "qwen",
      "args": ["--experimental-acp", "--approval-mode", "plan"],
      "env": {}
    }

Then start a session with a task, it will try to use edit like tool and ask for user permission. It is not as expected.

What did you expect to happen?

Don't use edit like tool in Plan mode, and exit with exit_plan_mode tool call.

⚠️ Missing Required Information

Thank you for reporting this issue! To help us investigate and resolve this problem more effectively, we need some additional information:

• Qwen Code version
• operating system information
• full output of the /about command (recommended)

How to provide this information:

Please run the following command and paste the complete output:

qwen
# Then in the interactive CLI, run:
/about

The output should look like:

CLI Version             0.0.14
Git Commit              9a0cb64a
Model                   coder-model
Sandbox                 no sandbox
OS                      darwin
Auth Method             qwen-oauth

Once you provide this information, we'll be able to assist you better. Thank you! 🙏

From the screenshot, it looks like the model is still trying to use edit tools even when --approval-mode plan is set.

The plan mode should restrict to read-only tools and then exit with exit_plan_mode.

Looking at packages/core/src/tools/exitPlanMode.ts, the tool exists, but maybe the tool filtering for plan mode isn't being applied correctly in ACP mode?

The tool availability might need to be checked against the approval mode setting.
