Tip: Use --safe-mode to Isolate Whether a Skill or Customization Is Breaking a Session

Claude Code Docs·medium signal

When Claude Code behaves oddly, launch with --safe-mode (or set CLAUDE_CODE_SAFE_MODE) to start a clean session with all customizations, hooks, and skills disabled, then re-enable incrementally to find the culprit. Pair with disableBundledSkills to rule out bundled skills specifically. This turns 'my config is haunted' debugging into a deterministic bisect.
