A beginner-friendly course for people who are new to Codex and can read a little code. It helps you build your first reliable Codex workflow: judge the task, state the request clearly, ask Codex to understand the project first, make a small code change, and check whether the result is trustworthy.
Explain Codex as a coding agent that acts on development tasks, and distinguish it from regular chat AI, code completion, and an IDE.
Judge whether Codex should execute a task directly, plan first, or only give advice based on goal clarity, scope control, verification, and risk.
Choose App/Web, IDE, CLI, or Cloud based on the context, action, permission, and acceptance needs of the task.
Rewrite a vague development request into an executable Codex task instruction with Goal, Context, Constraints, and Done when.
Write a read-only analysis instruction that asks Codex to read, explain, and plan before modifying files.
Design a Codex change task that has one goal, controlled scope, low risk, and a clear way to verify the result.
Choose a suitable verification method for a Codex task and ask Codex to explain verification results, failure causes, and unverified parts.
Inspect Codex's changed files, change reasons, verification result, and possible out-of-scope edits, then decide whether to ask, pause, or revert.
Identify Codex risks around deletion, overwrite, dependency installation, network access, databases, commits, deployment, and sensitive data, then rewrite risky instructions safely.
Review one Codex session and turn task expression, planning, small changes, verification, inspection, and risk control into a sustainable practice path.
