What's Wrong?

When using /add-dir to add an additional working directory, commands that access paths in that directory still prompt for permission — even when the user has broad allow rules like Bash(ls *) and Read in their settings.

What Should Happen?

The command should run without prompting, since:

• Bash/Read/Glob/Grep is in the allow list
• The directory was explicitly added via /add-dir

Error Messages/Logs

ls /c/Source/Server/MyProject/ | grep -i "SOMEFILE"
Run shell command

Do you want to proceed?
❯ 1. Yes
  2. Yes, allow reading from //c/EpicSource/TS2M/AnotherProject/M-routines/ from this project
  3. No

Steps to Reproduce

1. Configure global settings (~/.claude/settings.json) with:
   "permissions": {
   "allow": ["Read", "Glob", "Grep", "Bash(ls *)"]
   }
2. Start Claude Code in a project directory (e.g., /c/Source/Client/MyProject)
3. Use /add-dir /c/Source/Server/MyProject to add a second working directory
4. Claude runs a Bash or Read command that reads from the added directory
