Root Cause

  • The cwd contains only 9 files — the freezes are clearly not caused by large directory scans
  • Claude Code's @-style file reference autocomplete is instant in the same cmux session
  • This appears to be a Hermes implementation issue, not an environment problem. 9 files should scan in milliseconds on modern hardware.

Bug Description

Typing @ in the Hermes CLI immediately freezes the terminal session. CPU spikes to 70%+ and remains high for several seconds.

Environment

  • Platform: macOS
  • Terminal: cmux
  • cwd: /path/to/project/Architecture/
  • File count in cwd: only 9 files

Steps to Reproduce

  1. Start Hermes CLI inside cmux
  2. Type @
  3. Terminal immediately freezes/locks
  4. CPU spikes to 70%+

Expected Behavior

@-triggered autocomplete should be instant (like Claude Code) or at most take ~100-200ms.

Additional Context

  • The cwd contains only 9 files — the freezes are clearly not caused by large directory scans
  • Claude Code's @-style file reference autocomplete is instant in the same cmux session
  • This appears to be a Hermes implementation issue, not an environment problem. 9 files should scan in milliseconds on modern hardware.
