AgentRush is a sandboxed execution agent built for the Vultr Agent Rush hackathon. A user submits a task in the web UI; an LLM on Vultr Serverless Inference decomposes it into steps; URL fetches run on the orchestrator host with SSRF-pinned DNS; generated code executes inside a fresh Docker container per task: no network, read-only root fs, tmpfs workdir, capped memory/CPU/pids, all capabilities dropped, empty environment, wall-time kill, destroyed after the run. Every run returns a verifiable JSON record with per-step commands and sha256 of outputs. The demo video shows six live attacks — rm -rf, infinite loop, fork storm, env scrape, outbound curl, prompt injection — each dying at its intended boundary. Live public deployment on a Vultr VM (fra).
