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.

    goself-hostedself-repair
  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.

  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.
