Give an AI agent its own sandboxed cloud machine to work in — a full root Ubuntu VM (SSH, Docker, IPv4, all toolchains) where the agent can edit code, run commands, and host services without touching the user's host. Claude Code and Codex harnesses are preinstalled. Per-second billing, ~10x cheaper than E2B/Modal. Use as the execution environment for an autonomous agent.
- Pipes a download into a shell
- Reads credentials
- Installs packages

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

Agent sandbox (Box)
Use this when an autonomous agent needs a place to actually do work — clone a repo, run builds/tests, install packages, host a preview — isolated from the user's machine. Box is a full VM, so the agent has a real OS to operate in, and the Claude Code / Codex CLIs ship preinstalled.
Why Box
- Agent harness preinstalled — Claude Code + Codex on the box (near-unique vs raw sandboxes).
- Full machine — the agent can
apt install, run Docker, spawn long processes, expose ports. - Isolated & disposable — one box per agent/task;
box deleteto clean up. - Cheap at fleet scale — per-second flat pricing, ~10× cheaper than E2B/Modal.
Prereqs
curl -fsSL https://box.ascii.dev/install | sh, then box login "$BOX_API_KEY" --json.
Recipe
box_id="$(box new --json | jq -r 'select(.event == "ready") | .id')"
box ssh "$box_id" -- bash -s < ./agent-setup.sh # repo + deps + secrets
box prompt "$box_id" "Fix the failing tests and open a PR" --json # drive the on-box agent
box delete "$box_id" --jsonLimits
EU-only; disk-level snapshots; 100 active VMs soft cap. For memory-fork or 1000+ concurrent agents, see E2B/Modal.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
