Check if kubectl is bundled: Binary should be at `Resources/kubectl` (macOS) or similar platform path +2. Verify PATH: Ensure system PATH includes kubectl location +3. Reinstall: Download latest application bundle with kubectl included + +### Kubeconfig upload fails +**Problem**: "Failed to parse kubeconfig" error + +**Solutions**: +1. Validate YAML: Ensure kubeconfig is valid YAML format +2. Check contexts: Kubeconfig must have at least one context defined +3. Cluster URL: Ensure cluster URL is accessible +4. File format: Only .yaml or .yml files accepted + +### Commands not executing +**Problem**: Commands hang or don't execute + +**Solutions**: +1. Check timeout: Commands timeout after 30 seconds +2. Approval timeout: User must respond within 60 seconds for Tier 2 +3. Active kubeconfig: Ensure a kubeconfig is activated for kubectl commands +4. Review logs: Check audit log for denial reason + +### Approval modal not appearing +**Problem**: Tier 2 command doesn't show approval modal + +**Solutions**: +1. Check browser: Ensure JavaScript is enabled +2. Event listener: Modal listens for `shell:approval-needed` event +3. Tauri events: Verify Tauri event system is working +4. Console errors: Check browser console for errors + +## Future Enhancements + +**Planned Features**: +- Session-based approval preferences (approve all kubectl get for 1 hour) +- Command templating (save frequently used commands) +- Execution rollback (undo kubectl apply operations) +- Tier overrides (admin can override tier classification) +- Command history search and filtering +- Export execution history as CSV/JSON +- Integration with issue timeline (show commands executed during incident) +- Proxmox advanced commands (cluster management, backups) +- Multi-kubeconfig context switching within single file +- Auto-detection of ~/.kube/config on startup (pending AppHandle fix) + +**Stretch Goals**: +- Parallel command execution (run multiple commands concurrently) +- Command scheduling (execute command at specific time) +- Command chaining with dependencies (run X, then Y if X succeeds) +- Command output parsing (extract structured data from stdout) +- Integration with monitoring systems (auto-execute commands on alerts) + +## Related Documentation + +- [[Architecture]] - Overall application architecture +- [[Security-Model]] - Security architecture and threat model +- [[Database]] - Database schema and migrations +- [[IPC-Commands]] - Frontend-backend communication +- [[AI-Providers]] - AI integration and tool use + +## Version History + +- **v1.0.0** (2026-06-02): Initial release with three-tier safety classification, kubectl bundling, and multi-cluster support
