The demo worked. Six months later, no one could reproduce it.

Your best prompt is buried in chat history. The rules disagree. Tool connections live in one engineer's personal configuration. A new model arrives, and nobody can tell whether the system improved or quietly broke.

If that sounds familiar, the problem is not another weak prompt. It is agentic repo debt.

The Agentic Codebase is a practical architecture book for technical founders, senior engineers, and AI platform leaders who need agent work to become repeatable, governable, and maintainable.

The central idea: your repository is not merely where an agent's output lands. It is the operating system the agent works inside.

The book introduces STACK, a five-layer framework for designing that operating system:

  • Structure: make the codebase navigable, bounded, and legible.
  • Toolchain: standardize the shells, CLIs, runners, and environments that perform the work.
  • Agent configuration: turn scattered prompts into versioned rules, skills, roles, and workflows.
  • Connection layer: govern MCP servers, hooks, plugins, credentials, and tool contracts.
  • Knowledge and quality: manage memory, context, evals, observability, cost, and safety.
