The combined power-user stack

Every algorithm from this week in one list: control planes, research-origin loops, infra under the agent, and systems-language harnesses. Deduped, clone-and-run, no household CLIs.

01 — Power tools

The stack

  1. 01harnessGitHub
    Agenvoy

    agenvoy

    Self-hosted AI agent harness in a single Go binary. Writes, sandbox-tests, and repairs its own code. No Electron, no account.

    Use caseUse it as a local coding worker you can scp onto a box and run unattended against a failing test suite.

  2. 02toolGitHub
    cmux

    manaflow-ai

    Open-source Ghostty-based macOS terminal with vertical tabs and notifications for AI coding agents.

    Use caseUse it as the terminal surface when you are running a swarm of CLIs and need to see which one just finished.

  3. 03harnessGitHub
    Containarium

    FootprintAI

    Open-source agent runtime with SSH-native isolation, eBPF egress policy, Kubernetes and LXC backends.

    Use caseUse it to run untrusted coding agents with real network policy instead of hope.

  4. 04toolGitHub
    context-mode

    mksglu

    Context-window surgery for coding agents. Sandboxes tool output so the model sees the signal instead of a 40k-token log.

    Use caseUse it when your agent keeps blowing the window on build logs and you need the loop to survive a real compile.

  5. 05toolGitHub
    CUA

    trycua

    Open-source computer-use 2.0: drivers, cross-OS fleets, and benchmarks for training and evaluating desktop agents.

    Use caseUse it to give a coding agent a real desktop when the job is a GUI installer, not an API.

  6. 06harnessGitHub
    DeepCode

    HKUDS

    Open agentic coding from HKU: agent harness, loop engineering, multi-agent orchestration. Academic lab software that ships as a repo you run.

    Use caseUse it when you want a research harness with a real coding loop, not a chatbot with extra steps.

  7. 07toolGitHub
    Ghostex

    maddada

    Rust and GPUI native agent CLI manager for macOS. Ghostty terminals plus Codex-app UX, without Electron.

    Use caseUse it to manage a stack of native agent CLIs in Ghostty instead of a webview IDE.

  8. 08harnessGitHub
    graff

    justrach

    Fast agentic coding harness in Zig: multi-provider, MCP, workflows.

    Use caseUse it when you want a coding loop with systems-language latency, not a Node daemon.

    zigharnessmcp
  9. 09harnessGitHub
    Herdr

    herdrdev

    The runtime your coding agents live on. Not another chat wrapper: a place agents persist, resume, and share a machine.

    Use caseUse it when you want agents to survive a laptop sleep and pick up the same checkout, secrets, and tools.

    runtimepersistenceagents
  10. 10harnessGitHub
    Ironcurtain

    provos

    Secure runtime for autonomous agents. Policy from plain-English constitutions.

    Use caseUse it when you will not give a coding agent root and still want it to act.

    securityruntimepolicy
  11. 11harnessGitHub
    LoopX

    huangruiteng

    A long-horizon control plane that keeps coding agents on durable, governed work instead of one-shot chats. Power users treat it as the supervisor, not another model.

    Use caseUse it to keep an overnight refactor alive across tool crashes, with a human gate on the risky steps.

  12. 12harnessGitHub
    mcp-agent

    lastmile-ai

    Build effective agents with Model Context Protocol and small workflow patterns.

    Use caseUse it to compose MCP servers into a durable agent without standing up a full IDE plugin.

    mcpruntimeworkflows
  13. 13repoGitHub
    mini-SWE-agent

    SWE-agent

    The 100-line AI agent from the Princeton SWE-agent line. Research origin, radical simplicity, still beating bloated wrappers on SWE-bench-class work.

    Use caseUse it to throw a GitHub issue at a 100-line loop you can actually read, fork, and instrument.

    researchswe-benchminimal
  14. 14repoGitHub
    Mnemon

    mnemon-dev

    LLM-supervised persistent memory for agents: graph recall, cross-session knowledge, no vector-store cargo cult.

    Use caseUse it to give a coding agent a graph of the last two weeks of decisions so it stops re-deriving your architecture.

    memorygraphagents
  15. 15harnessGitHub
    oh-my-agent

    first-fluke

    A multi-agent harness that checks the work by artifacts, not vibes. Stop-hooks verify diffs, tests, and files before the run is allowed to claim success.

    Use caseUse it to stop a coding agent from declaring done when the test file was never written.

    verificationstop-hooksharness
  16. 16harnessGitHub
    oh-my-claudecode

    Yeachan-Heo

    Teams-first multi-agent orchestration for Claude Code. Not Claude Code itself: the swarm layer people bolt on.

    Use caseUse it to run a team of Claude Code workers on one repo with a shared plan file.

  17. 17toolGitHub
    oh-my-pi

    can1357

    A coding agent with the IDE wired in. Created New Year's Eve 2025, still being pushed daily.

    Use caseUse it when you want the agent and the editor to share one process instead of a plugin talking to a CLI.

  18. 18harnessGitHub
    Omnigent

    omnigent-ai

    Open-source meta-harness: one orchestrator that fans work across several coding agents. Born June 2026, already the loudest new control plane on GitHub.

    Use caseUse it to run three different coding agents on the same ticket and merge the first one that lands a green test.

    meta-harnessorchestrationopen source
  19. 19toolGitHub
    open-computer-use

    e2b-dev

    Computer-use agents on open models plus an E2B desktop sandbox. The open alternative to a vendor's computer-use API.

    Use caseUse it to let an open model click through a desktop app inside a throwaway VM.

    computer usesandboxopen models
  20. 20toolGitHub
    Orca

    stablyai

    An ADE for a fleet of parallel agents. Run any coding agent against your repo in parallel panes instead of one blessed CLI.

    Use caseUse it to fan the same failing test across four agents and keep only the patch that compiles.

  21. 21repoGitHub
    OSWorld 2.0

    xlang-ai

    Long-horizon computer-use benchmark. The eval serious desktop-agent repos cite.

    Use caseUse it to grade your own computer-use agent on real desktop tasks before you trust it on a laptop.

  22. 22harnessGitHub
    Warren

    jayminwest

    Treats coding agents as infrastructure, not terminal sessions. Isolation, lifetimes, and scheduling so a fleet of agents looks like a job queue.

    Use caseUse it to fire 20 isolated agent jobs against a monorepo without them trampling each other's working trees.

  23. 23toolGitHub
    Whip

    context-labs

    Fast coding-agent harness in Go. Tool-use loop, bubbletea TUI, provider-routable models. Created August 2026.

    Use caseUse it as a Go TUI coding agent when you want to swap models without swapping the loop.

  24. 24harnessGitHub
    CLI Agent Orchestrator

    awslabs

    AWS Labs multi-agent orchestration for AI coding CLIs. The interesting part is the coordinator, not the branded CLIs it wraps.

    Use caseUse it to run two vendor CLIs as workers under one policy instead of alt-tabbing between terminals.
