About

Detects ChatGPT Enterprise audit events that publish a GPT or update sharing for GPTs, skills, or projects (`gpt_publish`, `update_sharing`, `skill_share`, `project_update_sharing`). Broadening share scope can expose custom instructions, tools, or proprietary agent configurations beyond the original audience.
