I build Bounded Systems — infrastructure for letting AI agents do real engineering work without handing them unbounded authority. The bet: draw the boundary at the door — a scope-bounded set of capabilities an agent acts through — not the process, not the container.
Start here → robertdelanghe.dev — the thesis, and how it's built.
- 🚪 guest-room — the capability model in one library: rooms & doors, specs that run as tests.
- 🤖 prx — the agent-run work-unit CLI + the
@bounded-systems/*capability libraries. - 🌐 bounded.tools — what Bounded Systems is, in one page.
Recurse Center alum in Brooklyn, NY — happiest pairing on a hard problem. Came up through dev containers, state machines (xstate), and design tokens.
- ssh-doctor — A Bash script that diagnoses SSH setup issues and provides streamlined troubleshooting 🩺🔧
Shell - first-pass — A CLI tool that enhances your resume creation, aligns skills with job descriptions, and guides in building evidence-backed points 🚀📝
TypeScript - git-tidy — Flags local branches merged via PR but diverged from their merged state — keeps your repo tidy.
Go - synoptic-github — A dynamic template that auto-updates your README to showcase all your GitHub projects, offering a concise overview of your coding journey 🌟✨
