Code Review

Summary

This PR adds DISABLE_UPDATE_PROMPT=true to the .zshrc configuration to enable automatic oh-my-zsh updates without user prompts.

✅ Strengths

1. Clean implementation: The change is minimal and correctly placed before sourcing oh-my-zsh (line 22-23)
2. Valid oh-my-zsh setting: DISABLE_UPDATE_PROMPT is a documented oh-my-zsh environment variable that enables automatic updates
3. Consistent with automation goals: Aligns well with the repository's purpose of automated workspace provisioning
4. Proper location: Added within the oh-my-zsh conditional block where other oh-my-zsh settings live

💡 Considerations

1. Behavior clarification: The variable name might be slightly misleading:

   • DISABLE_UPDATE_PROMPT=true doesn't disable updates entirely
   • It disables the prompt and enables automatic updates
   • Updates still happen, just without user confirmation

2. Alternative approach: If you want to disable updates completely (which may be preferable for reproducibility), consider using DISABLE_AUTO_UPDATE=true instead

3. Documentation: The current behavior is clear from the PR description, but you might want to add an inline comment in the .zshrc file for future reference:

   # Auto-update oh-my-zsh without prompting
   DISABLE_UPDATE_PROMPT=true

🔒 Security & Best Practices

• Security: ✅ No security concerns. Automatic updates generally improve security by keeping oh-my-zsh current with patches
• Performance: ✅ No performance impact
• Test coverage: The test plan in the PR description is reasonable, though manual
• Code quality: ✅ Follows existing formatting and structure

📋 Recommendation

LGTM with minor suggestion: The implementation is correct and safe. Consider adding an inline comment for clarity, but this is optional. The change achieves the stated goal effectively.

Question for consideration: Do you prefer automatic updates (current approach) or completely disabled updates for reproducibility? Both are valid choices depending on your workflow preferences.
