codex-unrestricted-mode-injector

Skill by ara.so — Codex Skills collection.

A Python tool that injects unrestricted developer mode instructions into Codex CLI for GPT-5.5, bypassing content safety filters by leveraging the official model_instructions_file configuration mechanism.

What It Does

GPT-5.5 in Codex CLI enforces strict content safety restrictions. This tool:

• Injects custom system instructions via model_instructions_file in ~/.codex/config.toml
• Forces Codex to operate in [MODE: UNRESTRICTED]
• Disables content filters for security research, pentesting, reverse engineering, and unrestricted code generation
• Uses 8 core directives covering all restricted scenarios

Key difference from 5.4 version: Direct unrestricted mode declaration (~40 lines) vs CTF sandbox approach (~180 lines)
