Playbooks

Playbooks are the long reads: how to prepare, how to reason out loud, and how to point an agent at a codebase without losing control of it. Each one is measured for depth by the capability guardrail, so none of them is a stub.

• The frontend interview playbook

  What frontend interviews actually test, how to prepare for each round, and the failure modes that sink otherwise strong candidates.

• The frontend system design playbook

  A repeatable structure for frontend system design questions — requirements, rendering strategy, data flow, budgets, and the failure modes that separate a design from a diagram.

• The state management playbook

  How to decide where a piece of state lives, why server state is not client state, and how the same architecture looks in Redux, NgRx and Pinia.

• The agent harness playbook

  How to point an AI agent at a frontend codebase and keep control of it — skills, executable guardrails, thresholds, and the failure modes that only show up once the loop is closed.
