Claude Code in a Minute

Practical Claude Code usage from project instructions through advanced agent workflows.

• beginnerGetting startedClaude Code is Anthropic’s agentic coding CLI: you give a task in a repo, it reads context, edits files, runs commands, and iterates with your approval boundaries.
• beginnerCLAUDE.mdCLAUDE.md is a project instruction file Claude Code reads so it follows your repo’s conventions without being reminded every session.
• beginnerPlanningAsk Claude Code for a short plan and file list before it edits, so you can reject bad approaches cheaply.
• intermediatePermissionsClaude Code permissions define which tools and actions the agent may take without asking—and which require human approval.
• intermediateGit workflowUse a branch-per-task Git workflow with Claude Code so agent commits stay reviewable and reversible.
• advancedHooksClaude Code hooks are automation points around agent events—use them for checks and guardrails, not mystery side effects.
