oh-my-codex (OMX)
Like oh-my-zsh but for Codex — teams, memory, and TDD workflows

oh-my-codex (OMX) is an orchestration layer that wraps OpenAI's Codex CLI, adding everything Codex lacks out of the box: multi-agent team coordination, persistent memory, structured workflows, and async delegation. The analogy to oh-my-zsh is apt — it doesn't replace Codex, it supercharges it. The framework ships four canonical skills: $deep-interview for intent classification and clarification, $ralplan for structured implementation planning with trade-off review, $ralph for persistent completion loops that carry a plan to verified done, and TDD and code-review workflows. Since v0.13.1, every team worker runs in an isolated git worktree by default, preventing context bleed between parallel agents. A persistent-state MCP server carries memory across sessions. Built originally by Yeachan Heo and now also at github.com/scalarian/oh-my-codex, OMX has quietly accumulated nearly 3,000 GitHub stars. It's particularly powerful for developers already comfortable with Codex CLI who want to run parallel agents on large refactors or full-stack builds — the async delegation means no more hitting Codex timeout walls.

TUI-use
Let AI agents take control of interactive terminal programs

TUI-use is an open-source library that gives AI agents the ability to interact with traditional interactive terminal (TUI) applications — think vim, htop, ssh sessions, database CLIs, and legacy text-based UIs that were never designed for programmatic control. Instead of requiring a GUI or a REST API, TUI-use interprets terminal output as structured state and sends synthetic keystrokes back, enabling agents to "see" and "drive" any TUI application as if they were a human at a keyboard. The project was born from a real pain point: AI coding agents can call bash commands and write files, but they fail badly the moment a tool opens an interactive prompt waiting for user input. TUI-use solves this by building a state machine layer over PTY (pseudo-terminal) interfaces, letting agents read the current screen buffer, detect interactive prompts, and respond intelligently. It ships with adapters for common TUI patterns and a clean API that works with any LLM tool-use framework. The Show HN post attracted genuine interest from the ops and DevOps community — many existing workflows depend on tools that expose only an interactive terminal interface. TUI-use fills a real gap in the "AI agents that control computers" space by handling the long tail of CLI programs that have no API, no GUI, and no intention of ever getting one.
Reviewer scorecard
“The git worktree isolation per worker agent is the feature that sold me — parallel agents without stomping each other's context is exactly the problem I kept hitting in vanilla Codex. The $ralph persistent completion loop is genuinely useful for large multi-file refactors.”
“This is the missing piece for automating legacy ops workflows. Half my toolchain is interactive TUI apps that choke every agent pipeline — TUI-use just quietly solves that. The PTY state machine approach is clever and the API is clean.”
“Orchestration layers on top of CLI tools tend to accumulate abstraction debt fast. OMX is already on v0.13.1 with breaking changes between minor versions. Unless you're a Codex power user, you'll spend more time debugging the orchestration layer than doing actual work.”
“Screen-scraping terminal output to infer state is fragile — any change in terminal colors, locale, or version will break your parser. This works fine for demos but I'd want to see battle-hardened error recovery before running it against anything production-critical.”
“We're in the oh-my-zsh moment for AI agent CLIs — community-built orchestration layers will fragment and recombine until a few patterns win. OMX is one of the more principled early experiments, and its worktree-isolation approach will likely influence how official tooling handles parallelism.”
“The real unlock here is making 40 years of terminal software suddenly agentic without a single line change from the original developers. TUI-use could quietly become the bridge that lets AI agents inherit the entire unix toolchain ecosystem.”
“This is deep CLI territory — not designed for non-developers at all. If you're a developer who lives in the terminal and wants to push Codex further, it's interesting. Otherwise, skip.”
“Not my usual domain but I can see this saving hours for anyone managing servers — having an agent that can actually ssh in and navigate interactive prompts without getting stuck is genuinely useful. The demo videos make it look surprisingly smooth.”
