What it does

Your coding agent resends files, diffs, instructions, and logs it has already seen. Halv cleans that wasted context locally before each request reaches the model—so you keep the same CLI, login, model, and subscriptions while getting far more work from your plan. It supports Claude Code, Codex, Kimi, and GLM, with split terminals, multi-agent workflows, local sandboxing, a Crux code index, and a receipt showing the usage saved on every answer. Available on macOS, Windows, and Linux.

Run Claude Code, Codex, Kimi, and GLM in one desktop workspace. Halv recorded 57.1% lower model cost across 42 paired SWE-rebench repetitions, with 25 passes per arm.

Agents re-read the same files, paste whole command logs into context, and run the premium model on trivial steps. Halv runs your agents in one app that filters, compresses, and routes each task to the model it needs. A model keeps no memory between requests, so your agent sends the full conversation every time — the prompt, every file it read, every command result, all of it, again. By turn nine, most of what you send is a copy of what you already sent. That copy is what empties a five-hour window by lunch. Re-read files, pasted command logs, and premium models on trivial steps. Halv closes each leak inside the workspace, so you can focus on what you’re building. Command output filtering…from halv.ai

    Hi! I’m Nathan: an ML Engineer at Mozilla.ai: I built agent-of-empires (aoe): a CLI application to help you manage all of your running Claude Code/Opencode sessions and know when they are waiting for you. - Written in rust and relies on tmux for security and reliability - Monitors state of cli sessions to tell you when an agent is running vs idle vs waiting for your input - Manage sessions by naming them, grouping them, configuring profiles for various settings I'm passionate about getting self-hosted open-weight LLMs to be valid options to compete with proprietary closed models.

  • Retain – A unified knowledge base for all your AI coding conversationsJan 2026 · github.com · ▲45

    Hey HN! I built Retain as the evolution of claude-reflect (github.com/BayramAnnakov/claude-reflect). The original problem: I use Claude Code/Codex daily for coding, plus claude.ai and ChatGPT occasionally. Every conversation contains decisions, corrections, and patterns I forget existed weeks later. I kept re-explaining the same preferences. claude-reflect was a CLI tool that extracted learnings from Claude Code sessions. Retain takes this further with a native macOS app that: - Aggregates conversations from Claude Code, claude.ai, ChatGPT, and Codex CLI - Instant full-text…
