One Subscription for Every Coding Agent

You do not have one AI subscription. You have a portfolio: a Claude plan, a Codex account, a Grok login, a free Gemini tier, maybe a work account that must stay separate from your personal one. Each one is useful. Together they are a mess of browser tabs, scattered terminals, and configuration files — and every context switch costs you the one resource no model can give back: your attention.

One Subscription for Every Coding Agent shows you a better way. The answer is not a mythical universal plan that replaces them all. It is a workspace — Orca — that becomes the single front door to every agent you already pay for. One application to launch agents, isolate their work in git worktrees, watch them in split panes, and review every change in a single diff viewer. The providers stay separate. The workflow finally becomes coherent.

Caleb Mercer walks you through the complete system, from first principles to production habits. You will learn the three-layer model that clears up most tool confusion (model vs. agent vs. workspace), the worktree loop that makes parallel agent work safe and reviewable, and the economics of subscription portfolios: when to route a task to your best model, when a cheaper agent will do, and how to stop paying for access with your attention.

Along the way you will see real workflows: three agents tackling three problems at once, long test suites running while documentation gets drafted, and provider limits handled by routing instead of waiting. You will learn why the boring loop — brief, watch, review, commit or discard — is exactly what you want when managing autonomous processes, and why a developer who cannot review one diff carefully will not benefit from five agents producing five diffs.

Whether you are a solo developer drowning in tabs or a team lead thinking about agent-assisted development, this book gives you a practical, provider-independent system for getting more from the subscriptions you already have.
