Slicer Agent Skills

Agent Skills for Slicer — instant Linux microVMs powered by Firecracker.

Teach your AI coding agent how to launch, manage, and work with Slicer microVMs for sandboxed builds, E2E tests, Docker workflows, CI, and isolated dev environments.

Available Skills

use-slicer

skills/use-slicer

Comprehensive skill covering the full Slicer workflow — connecting to daemons (macOS, Linux, hosted box), creating VMs, running commands, copying files, port forwarding, agent sandboxes, and more.

Works from macOS (via slicer-mac) and Linux hosts.

use-slicer-worktrees

skills/use-slicer-worktrees

Move a git worktree or repository into a Slicer microVM with a working, self-contained .git. Covers slicer wt push / pull / list — push code in, let a VM or coding agent work and commit, then fast-forward the commits back onto your host branch. The recommended way to put a git project into a provision-only agent sandbox.

use-slicer-proxy

skills/use-slicer-proxy

Filter, audit, and inject secrets into HTTP(S) egress from Slicer microVMs with Slicer Proxy. Covers default-deny allow rules (host / path / method / port / TTL), credential injection (Bearer, Basic, and OAuth for Claude/Codex/Copilot/xAI), audit mode for path discovery, and TCP passthrough — on both Linux and macOS.

use-s3-rustfs

skills/use-s3-rustfs

Install and run RustFS (S3-compatible object storage in Rust) inside a Slicer VM, and talk to it from boto3, aws-cli, or mc. Covers the non-interactive installer invocation, default credentials/ports, and common client pitfalls (path-style vs virtual-host, SigV4 region quirks).

use-k3sup

skills/use-k3sup

Single-node and HA K3s provisioning with k3sup / k3sup-pro, using either:

• local in-VM install (k3sup install --local)
• remote install from your machine (--host / --user, typically ubuntu)
• Slicer VM flows and SSH setup for API-launched guests

Installation

npx (recommended — works with 40+ agents)

npx skills add slicervm/agent-skills

This installs the skills into whichever AI coding agents you have (Claude Code, Amp, Cursor, Codex, Gemini CLI, etc.).

Claude Code Plugin

/plugin marketplace add slicervm/agent-skills
/plugin install use-slicer@slicer
/plugin install use-slicer-worktrees@slicer
/plugin install use-slicer-proxy@slicer
/plugin install use-s3-rustfs@slicer
/plugin install use-k3sup@slicer

Install only the plugin skills you need; use-s3-rustfs, use-slicer-worktrees, and use-slicer-proxy all assume use-slicer is also installed. Claude Code exposes plugin skills under their plugin namespace, for example /use-slicer:use-slicer.

Manual

Clone and copy the skill into your agent's skills directory:

git clone https://github.com/slicervm/agent-skills.git
cp -r agent-skills/skills/use-slicer .claude/skills/   # Claude Code
cp -r agent-skills/skills/use-slicer .agents/skills/    # Amp / Codex
cp -r agent-skills/skills/use-slicer .cursor/skills/    # Cursor

Example Prompts

Launch a Slicer VM and run my test suite inside it

Forward Docker from my Slicer VM so I can build containers locally

Set up a k3s cluster in a Slicer VM

Copy my project into a VM, build it, and bring back the binary

Provision a Codex sandbox and push my git worktree into it

Lock down a VM's egress so it can only reach the npm registry

What is Slicer?

Slicer turns a Linux host into a private microVM cloud. VMs boot in 1–3 seconds with full systemd, internet access, and SSH. It targets:

• Sandboxed code execution and CI runners
• Preview environments and AI agent sandboxes
• Docker/container workflows with port forwarding
• Kubernetes (k3s) clusters for testing
• GPU/PCI passthrough workloads
