MicroCodex

About

MicroCodex is an independently written C++ client for the OpenAI Codex service: a terminal coding agent offering one-shot prompts and an interactive TUI, local coding tools for file read/write/edit, bash execution, and glob, durable conversations, and automatic context compaction. It logs in with your ChatGPT plan through OAuth (including device-auth for headless machines), stores credentials alongside Codex's own under ~/.codex, and discovers Codex skills installed under $CODEX_HOME/skills, so an existing Codex user's setup carries over. The bash tool runs behind a lexical safety gate that blocks destructive commands like rm -f and git reset --hard — explicitly not a sandbox — and MCP support is not yet implemented. It builds for macOS (Apple Silicon and Intel) and Linux, and targets developers who want a tiny, dependency-light alternative frontend to the Codex service.
