claude-mem is an open-source memory compression plugin that gives Claude Code a persistent brain across sessions. It hooks into six Claude Code lifecycle events to automatically capture tool observations, compress them into semantic summaries, and store everything in a local SQLite + Chroma vector database. When a new session starts, relevant context is injected automatically — no copy-pasting, no re-explaining architecture decisions you made last week. The system achieves roughly a 10x token reduction through progressive disclosure: it retrieves only what's relevant for the current task rather than dumping everything into context. Developers can query their memory store via natural language through MCP tools (search, timeline, get_observations), and a built-in web viewer at localhost:37777 lets you inspect memory streams visually. Privacy controls via <private> tags let you keep sensitive content out of the store. Install is a single npx command, and it works with Claude Code, Gemini CLI, and OpenClaw gateways. The project hit 48K+ GitHub stars and is clearly scratching a real itch: the loss of context between sessions is one of the most consistent pain points for AI-assisted development.

Oh My codeX (OMX)
Hooks, agent teams, and persistent state for the OpenAI Codex CLI

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.
Reviewer scorecard
“This solves the most annoying thing about AI coding assistants — having to re-explain your entire project structure every single session. The six-hook lifecycle integration is thoughtful and the 10x token reduction claim is plausible if the retrieval is tuned well. Single-command install seals it.”
“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.”
“Running a background Python Chroma server plus SQLite on every dev machine adds meaningful complexity and failure modes. The AGPL-3.0 license is a red flag for commercial projects — the non-commercial Ragtime component inside makes it effectively dual-license poison for most teams. Wait for a cleaner, simpler implementation.”
“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.”
“This is the beginning of AI development tools that genuinely learn your codebase over time. Today it's session memory — in 18 months it'll be team-wide institutional knowledge that onboards new agents automatically. The 48K GitHub stars in days signal real market pull.”
“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.”
“As someone who writes in sessions that span days, having context automatically restored without a 10-minute recap ritual is genuinely valuable. The web viewer UI for inspecting memory streams is a nice touch — makes the invisible visible.”
“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.”
