Why it is worth attention

It uses a direct jailbreak strategy (declaring unrestricted developer mode, disabling all filters) with only ~40 lines of instructions, covering security research, pentesting, reverse engineering, and NSFW scenarios, while relying on the official config mechanism without binary modification.

Who it is for

  • Security researchers
  • Penetration testers
  • Reverse engineers
  • AI red-teamers

Use cases

  • Performing SQL injection tests after injection
  • Conducting reverse engineering tasks
  • Generating NSFW fictional content (as claimed)
  • Testing AI response boundaries in offensive security

Strengths

  • Uses only official Codex CLI configuration (no binary/network tampering)
  • One-command deployment and undo
  • Short instruction set (~40 lines) compared to predecessor
  • Supports external instruction files and dry-run preview

Considerations

  • Only works with GPT-5.5 inside Codex CLI
  • Requires restart of Codex CLI to take effect
  • Basic CLI version; full UI version is in another repository (Codex-X)
