claude-code - 💡(How to fix) Fix Edit permission glob ** pattern does not recursively match nested directories [5 comments, 2 participants]

Description

The ** glob pattern in Edit() permission rules (settings.json allow list) does not recursively match files in deeply nested subdirectories. This appears to be a regression -- the same configuration worked in earlier versions.

Reproduction

settings.json allow rule:

"Edit(/Users/me/.config/myproject/**)"

File being edited:

/Users/me/.config/myproject/worktrees/my-branch/scripts/db.py

Expected: Auto-approved (path is under the allowed ** pattern) Actual: Prompts for user approval

Root cause hypothesis

Python's pathlib.PurePath.match() does not support ** for recursive directory matching the way POSIX glob or fnmatch do:

from pathlib import PurePath

path = PurePath('/Users/me/.config/myproject/worktrees/branch/scripts/file.py')

path.match('/Users/me/.config/myproject/**')        # False (unexpected)
path.match('/Users/me/.config/myproject/*/*/*/*')    # True

If Claude Code uses PurePath.match() to evaluate permission patterns, ** will silently fail to match files more than one level deep. fnmatch.fnmatch() handles ** correctly for this case.

Environment

• Claude Code version: 2.1.133
• OS: macOS (Darwin 25.4.0)
• The pattern matches files directly in the allowed directory (1 level deep) but fails for 2+ levels of nesting.

Impact

Users with Edit(/path/**) allow rules get unexpected approval prompts for nested file edits. This affects git worktree workflows where files are several directories deep under the allowed root.
