Genie Sessions: TCR Skill

In this live "Genie Session," the host demonstrates the Test‑Commit‑Revert (TCR) workflow, a disciplined programming pattern where every code change is immediately validated by tests; passing tests trigger a commit, while failures cause an automatic revert. By forcing small, green‑only increments, TCR reduces debugging overhead and encourages continuous quality. The unscripted format highlights how developers can adopt this approach even when no established playbook exists, echoing the broader shift toward exploratory development where teams must invent new processes on the fly.

The session’s technical core revolves around creating a Cursor skill that enforces TCR automatically. Using the Cursor AI assistant, the host defines a custom skill that runs the test suite after each micro‑change, commits on success, and reverts on failure, logging the error. This integration showcases how AI‑driven tooling can embed rigorous workflows directly into the development loop. The host also addresses practical constraints such as the limited context window of large language models, recommending strategies like chunking work, pinning critical files, and starting fresh chats to maintain performance. Tool selection is portrayed as experimental—Cursor is chosen over competing services due to credit availability, underscoring the need for flexible, cost‑aware tooling choices.

Beyond the immediate code demo, the conversation pivots to the business potential of reusable AI skills. The host envisions a marketplace for skill libraries that automate best‑practice patterns like TCR, offering developers a plug‑and‑play productivity boost. By documenting the workflow, iterating live, and openly sharing the repository, the session illustrates how developers can monetize expertise while contributing to a communal knowledge base. This approach aligns with the current era of rapid experimentation, where creating and selling modular AI‑enhanced development tools can become a viable revenue stream for tech professionals.
