Labs

Experiments in AI-native product development. Real builds, real OAIS (Operating AI System) choices: different stacks, context, and governance. A place to try things, ship them, and compare what works. Each case study is a live product plus the OAIS behind it. The differences between them are spelled out so you can see the tradeoffs.

Angry Letters

Started May 2025

Problem

Ship a full SaaS (payments, creator programs, admin, AI-assisted content) as a solo founder with limited bandwidth. Need a Cursor-centric operating model that stays maintainable.

Stack

Product: live SaaS stack (payments, email, etc.). OAIS: separate repo (angry-letters-oais), Cursor-centric, its own context and documentation structure.

Operating system used

Cursor-centric workflow; context and docs separate from the matthewheyman.com OAIS. Built and shipped as an experiment in a different operating model.

Documentation structure

OAIS lives in angry-letters-oais (oais/ folder). README, INSTALL, and agent/context docs in that repo.

Lessons learned

Separate OAIS per product keeps context clean. Solo build benefits from a single, opinionated workflow rather than a one-size-fits-all system.

Reusable assets

Clone or download the OAIS repo; drop oais/ into your project. See INSTALL in the repo.

Problem

Run a credible primary site and a Labs surface with one OAIS that can bootstrap new products and support multi-feature execution with human gates.

Stack

Static site (HTML/CSS). OAIS in repo (oais/); published separately at matthew-heyman-oais for clone/download.

Operating system used

Canonical index, lifecycle workflows, bootstrap mode, Tier A/B/C authority. Emphasizes human-in-the-loop alignment gates and convergence over speed and blind AI trust. Tool-agnostic.

Documentation structure

OAIS in matthew-heyman-oais. Documentation and agents live in the repo; drop oais/ into another product.

Lessons learned

Stage and gate guardrails (validate preceding stage, no implementation before Alignment sign-off, clarification-seeking) reduce agent drift. Portable oais/ folder keeps product and OS separate.

Reusable assets

Clone or download matthew-heyman-oais; copy oais/ into your project root. See oais/INSTALL.md.
