Oh My codeX (OMX) is an orchestration layer that sits on top of OpenAI's Codex CLI and adds the features that Codex itself left out: lifecycle hooks, multi-agent team coordination, persistent project state, and a headless display framework. Think of it as oh-my-zsh, but for your Codex agent runtime. The project's core innovation is its team runtime: running 'omx team 3:executor "refactor auth to OAuth"' spawns three parallel agents, each working in an isolated git worktree to avoid merge conflicts. Since v0.13.1, worktree isolation is on by default. OMX also ships 33 specialist agent prompts and 36 workflow skills out of the box — including deep interview, planning, and code review flows — plus a '.omx/' directory that persists project state between sessions. Built by Yeachan Heo and hitting 26.9k GitHub stars, OMX is MIT licensed and installable in seconds: 'npm install -g @openai/codex oh-my-codex && omx --madmax --high'. It requires tmux on macOS/Linux for team features. The project has become the de-facto community layer for serious Codex power users who want more than a raw CLI.

RAG-Anything
Unified multimodal RAG pipeline for docs, images, tables, and mixed content

RAG-Anything is an open-source framework from the Hong Kong University of Science and Technology (HKUST) Data Science group that extends Retrieval-Augmented Generation to handle arbitrary document types in a single unified pipeline. While most RAG implementations are text-only and break on PDFs with tables, charts, or mixed layouts, RAG-Anything handles text, images, tables, mathematical formulas, and mixed documents without preprocessing hacks. The framework introduces a universal document parser that preserves semantic structure across formats, a heterogeneous chunking strategy that chunks different modalities independently before linking them, and a cross-modal retriever that can match a text query against an image or table just as naturally as against a text passage. It integrates with LightRAG for graph-based knowledge organization. Trending on Hugging Face today, RAG-Anything addresses one of the most common failure modes practitioners hit when moving RAG from toy demos to real enterprise documents. Legal PDFs with tables, scientific papers with figures, slide decks with mixed layouts — all of these now work out of the box.
Reviewer scorecard
“Parallel agents in isolated git worktrees is the feature every Codex power user has been waiting for — no more merge conflict hell when you run multi-step tasks. The 36 built-in workflow skills mean you're not starting from scratch. Install this the moment you start using Codex CLI seriously.”
“The 'RAG on real documents' problem is genuinely hard and genuinely painful. Every enterprise RAG project I've worked on has hit the table-in-PDF wall within the first two weeks. If RAG-Anything's cross-modal retrieval actually works reliably, this belongs in every production RAG stack.”
“Twenty-six thousand stars in three weeks is exciting but also a yellow flag — trending repos get abandoned fast, and this is a one-person project with a single maintainer. Also, tmux as a hard dependency for team features is going to break in CI/CD and containerized environments. Wait for v1.0 stability before putting this in a real workflow.”
“Multimodal document parsing is notoriously benchmark-sensitive — performance on academic paper datasets doesn't generalize to messy real-world enterprise docs. Test this thoroughly on your actual document corpus before swapping it in. The cross-modal retrieval quality depends heavily on the underlying VLM, which adds another dependency to manage.”
“OMX is the community layer that turns Codex from a demo into a development runtime. The pattern of community-owned orchestration shells layered on top of AI CLIs is going to become standard — and the projects that nail the UX now will define what 'agentic coding' means for the next cohort of developers.”
“The real-world knowledge most enterprises need is locked in heterogeneous documents — not clean text. A RAG layer that treats all document types as equal citizens is the prerequisite for any serious enterprise knowledge AI. This is infrastructure that becomes more valuable as document volumes scale.”
“The concept of skills-as-folders with a SKILL.md metadata file is an elegant design pattern that any non-developer can understand and remix. This lowers the bar for customizing your agent runtime without writing framework code — that's a meaningful UX step forward for AI tooling.”
“Creators who do research from mixed sources — brand guidelines in PDFs, competitor analysis in slides, market data in Excel exports — would immediately benefit from being able to query across all of those at once. This is genuinely useful outside the developer audience too.”
