You have the tools. Claude Code, Codex, an open-source LLM, maybe a vector store and a task queue. What you don't have is a repeatable system for making the hundred small decisions that determine whether your agent product ships cleanly or collapses under its own complexity. This is that system. The Agent Architecture Operating System gives technical indie developers and AI-native founders an opinionated, end-to-end framework covering every major decision point in the agent build cycle – from choosing your architecture pattern on day one to running behavioral evals before you ship to keeping costs and reliability in check in production. It's not a tutorial. It's a decision-making infrastructure you install into your build process and reuse across every agent product you touch. If you're tired of reinventing the wheel on orchestration choices, testing strategy, and deployment guardrails every time you start a new project, this gives you the scaffolding to stop doing that.
What's included
- A scored architecture decision tree that walks you through choosing between single-agent, multi-agent, and hierarchical orchestrator patterns – with explicit trade-off criteria so your choice is defensible, not just instinctive
- A five-pattern orchestration library covering canonical agent coordination approaches, each with when-to-use criteria and annotated pseudocode you can adapt directly to your stack
- A three-layer eval and testing playbook with fill-in templates for prompt regression tests, workflow assertions, and behavioral evals – so you have a structured testing strategy, not just ad hoc spot checks
- A deployment and reliability checklist covering rate limit handling, retry logic, observability setup, cost guardrails, and graceful degradation – the production concerns that bite you if you skip them
- A decision log and failure modes reference with reusable templates for recording architectural choices and a catalog of recurring agent product failure patterns to help you avoid repeating known mistakes
- A 30-60-90 day adoption milestone plan that sequences how to embed the full system into your build process incrementally, so it becomes a working habit rather than a document you read once and shelve
