MicroVM sandboxes meet self-evolving harnesses and external control planes

Power users get clone-and-run isolation layers, observability-driven harness evolution, and policy engines that sit outside the model. The through-line is infrastructure you wire into agent loops yourself rather than another chat IDE.

01 — Power tools

The stack

  1. 01harnessGitHub
    DevOps Agent Harness↗

    stwins60

    Model-agnostic harness that turns any coding agent into a governed DevOps engineer with policy, approvals, audit, secret redaction and rollback enforced outside the LLM.

    Use caseUse it to drive Jira-to-PR incident response or Kubernetes diagnosis while every tool call hits an external policy engine.

  2. 02toolGitHub
    SideKernel↗

    minoansecurity

    Zero-dependency macOS microVM sandbox using only Apple frameworks and a Rust guest agent for Claude and other coding agents.

    Use caseUse it to launch an ephemeral Linux microVM from the current directory with sclaude or scodex wrappers.

    Awesome Harness Engineering↗

    ai-boost

    Curated map of harness engineering primitives covering context, tools, memory, sandboxes, permissions, evals and observability.

    Use caseUse it to map the five harness primitives and find the matching open-source module for each.

  4. 04harnessGitHub / DEV
    Multiharness↗

    eror-0

    Go multi-agent orchestrator that delegates planner, implementer and reviewer roles across open coding harnesses with iterative review loops.

    Use caseUse it to run a Codex planner plus OpenCode executor team on one folder with configurable reasoning levels.

    Agent HQ primitives (open ecosystem view)↗

    GitHub

    Mission-control style orchestration surface that unifies assignment, steering and tracking of multiple coding agents across GitHub, VS Code, mobile and CLI.

    Use caseUse it to study how a single control plane can route work to heterogeneous agents while keeping enterprise review and metrics.

    Google Agent Compute Engine preview: hardware-isolated microVMs for Gemini work agents↗

    Google Cloud

    Google describes a compute service already powering Gemini agents that separates the trusted harness from a hardware-isolated microVM sandbox with fast checkpoint and Titanium offload. Customer preview is slated for the coming months alongside Agent Gateway model routing.
