Description

Entire worktree directories sometimes disappear when multiple AI agents are modifying their separate branches concurrently in a local setup.

Environment

• Setup: Local only (no remote operations)
• Scenario: Multiple AI agents working on separate branches concurrently
• Operations: Concurrent modifications, sometimes with rebases onto main

Expected Behavior

Worktree directories should remain stable and accessible even when multiple agents are working concurrently.

Actual Behavior

The entire worktree directory sometimes disappears, making the branch and work inaccessible.

Potential Causes

• Race conditions during concurrent git operations
• File system issues during simultaneous writes
• Git garbage collection running during active operations
• Corrupted .git state from concurrent access

Impact

• Complete loss of work if not backed up
• Requires manual cleanup and recreation of worktrees
• Disrupts parallel AI development workflows
