Part 1 · AI Coding Agents: Claude Code, Copilot, Cursor, Codex

OBJECTIVE: learn what AI coding agents are and how to use the main ones safely and well — so you can build software many times faster while staying in control. WHAT WE COVER: • What coding agents are and how they differ (terminal, IDE, cloud agents) • Setting up Claude Code, GitHub Copilot, Cursor and OpenAI Codex • The settings that matter in every tool: model and reasoning effort, permission modes, project instruction files, context • The safe workflow: plan → small steps → review the diff → test → commit • Security and cost basics • Mini project: the same small feature built with two tools, compared AFTER THIS PART YOU CAN: • Pick the right coding agent for a task and set it up properly • Give clear instructions and keep the agent on track • Review, test and safely ship AI-written code
