The gns3_create_node tool supports fuzzy matching for template names:
| Error Code | Meaning | Resolution |
|---|---|---|
| GNS3_NOT_FOUND | Node or project doesn't exist | Check name/ID |
| GNS3_CONFLICT | Node already running/stopped | Check current state first |
| GNS3_VALIDATION | Invalid template name | Use gns3_list_templates to find valid names |
