The build system

Not vibe coding. A multi-model studio system.

Every Saint Marlo build runs through custom agent harnesses, per-project prompt libraries, and a rotating fleet of frontier models — Codex, Google Jules, Claude Code, Lovable, Replit, Cursor, and GitHub — chosen per task to play to each model's strengths.

We study the top coding signal daily — Twitter, Reddit, Google Developer accounts, Anthropic and OpenAI release notes — and fine-tune every prompt, agent, and harness against the latest model behavior. It's a craft, not a shortcut.

01
Intel loop

Daily review of frontier-model updates, prompt research, and tooling drops from Twitter, Reddit, Google Developer accounts, Anthropic, OpenAI, and the Cursor / Codex / Jules / Replit changelogs. Anything worth keeping is folded into the harness inside a week.

02
Custom agent harnesses

Per-project agent rigs — planner, coder, reviewer, QA — versioned and iterated on continuously. Not one-shot prompts, not vibes. Real scaffolding tuned per codebase.

03
Prompt libraries

Project-specific prompt packs maintained per app and re-tuned weekly against new GPT, Codex, Claude, and Gemini behavior. When a model shifts, the prompts shift with it.

04
Multi-model orchestration

Codex, Google Jules, Claude Code, Lovable, Replit, Cursor, and GitHub all in rotation. Each task is routed to the model that wins on it — Claude for refactors, Codex for long-horizon agents, Lovable for UI velocity, Cursor for surgical edits, Jules for async PR work.

05
Harden

Versioned source of truth, Supabase / Lovable Cloud, auth, RLS, edge cases, perf budgets (INP < 200ms, LCP < 2.5s), and regression-free diffs. No demos shipped as products.

06
Ship & operate

Domain, PWA, TestFlight, App Store, monitoring, and ongoing operation — not just launch day. Every product stays in the harness after release.

Launch path

App Store pipeline

Each project moves through the same shipping ladder — from live web app to PWA, then TestFlight, submission, and public launch.
