Claude Code for Developers | Automate Workflows with Claude AI

If you write code for a living, the Claude Code terminal workflow is where Claude stops being a chat assistant and becomes full-stack infrastructure — executing multi-step tasks, committing to Git, and running autonomous coding sessions while you sleep.

Claude Code is a command-line AI agent from Anthropic that integrates natively with your terminal and major IDEs including VS Code, JetBrains, and Cursor. Install it with a single command on macOS, Linux, or WSL, authenticate your Anthropic account in under two minutes, and it operates scoped to your current project folder — reading files, writing features, running tests, and committing to Git. Sub-agents, hooks, and auto mode extend it into programmable development infrastructure that handles complex multi-step tasks autonomously.

Installation: One Command, Auto-Updates Included

Anthropic ships official installers for every major platform — macOS, Linux, and WSL. The native installer auto-updates in the background, which means you stay on the latest version without ever running an upgrade command. On Homebrew, the manual command is brew upgrade claude. On Windows via winget it is the equivalent command, but the behavior is otherwise identical across platforms.

First-run setup takes under two minutes. Authenticate with your Anthropic account, choose a default model, and optionally configure an organisation if you are on a team or enterprise plan. After that, running claude anywhere on your system drops you into an interactive session scoped to wherever you launched it.

The Terminal Workflow: Sessions That Remember Where You Left Off

The working pattern is two commands: cd my-project then claude. That drops you into an interactive Claude Code session scoped to your current folder. From there you work in prose — ask Claude to read files, write features, refactor a module, run tests, or commit to Git. The session keeps full context across every turn.

What makes the Claude Code terminal workflow genuinely different from a chat interface is session persistence. Close the terminal, reopen it the next morning, and claude -c continue picks up exactly where you left off — full context of what you were working on intact. Other flags worth knowing: --model forces a specific model for the session, -p enables non-interactive print mode for scripting, and you can chain Claude into shell pipelines for programmatic output.

IDE Integrations: VS Code, JetBrains, and Cursor

Claude Code integrates natively with three major development environments. In VS Code, install the Claude Code extension from the marketplace and you get an in-editor panel where Claude can see your full file tree, open editors, and current selection — not just a pasted snippet. JetBrains has a plugin available through the JetBrains Marketplace with the same capabilities: inline chat, inline diffs, and inline edits without leaving the editor. Cursor and other editors either have community-maintained integrations or work cleanly with a terminal in a split pane.

The IDE integration matters because Claude is not working blind. It sees the entire project structure, which changes the quality and accuracy of every suggestion it makes — context that a chat window can never replicate.

Slash Commands and Hooks: Baking Standards Into the Environment

Inside any Claude Code session, slash commands handle common workflows: /debug, /simplify, /batch, /loop, /clear, /compact, /model, and /help. Custom commands and skills are unified — drop a folder at .claude/skills/mycommand with a skill.md file and it becomes available as a slash command in every subsequent session.

Hooks are scripts that fire at specific points in the Claude Code lifecycle, similar to Git hooks but scoped to Claude's actions. A pre-commit hook runs your linter before Claude commits any code. A post-tool-use hook logs every file Claude modifies during a session. A notification hook pings your phone when a long-running task finishes. These hooks enforce coding standards automatically — they apply to every session, not just when you remember to check.

Sub-Agents: Turning Serial Work Into Parallel Investigations

For complex tasks, Claude Code can spawn sub-agents — specialised helpers that run in parallel. The concrete impact: a serial codebase investigation becomes concurrent. Ask Claude to find every place the codebase calls a legacy API. Claude might spawn three sub-agents simultaneously, each covering a different section of the codebase, then aggregate their findings into a single report. What would have taken three sequential passes completes in one parallel execution.

Define your own sub-agents with specific tool restrictions and system prompts by writing a YAML front-matter file and dropping it in the claude-agents folder. Claude invokes the right sub-agent automatically when the task matches its definition. Having trained over 79,000 students across 74+ courses in AI and automation, I find this the most underused feature in the toolkit — the shift from one assistant to a coordinated team of specialised agents changes what you can delegate entirely.

Auto Mode, Thinking Modes, and Permissions

Auto mode gives Claude expanded autonomy for multi-step tasks. The pattern: describe the task, grant permissions upfront, walk away. A bounded example — Investigate this bug. Reproduce it. Write a failing test. Fix it. Verify tests pass. Claude plans and executes the full sequence. A larger example: kick off a REST-to-gRPC service migration on Friday afternoon, check the PR Monday morning, review and merge. Done.

Start with small, well-scoped tasks in auto mode. Watch what Claude does. Calibrate how precise your prompts need to be before handing it anything with significant blast radius.

Thinking modes scale Claude's internal reasoning depth across four levels: think adds slight deliberation above the default, think hard enables deeper planning, think harder pushes further still, and ultra think activates the maximum extended thinking budget. Use ultra think for architectural decisions or complex refactors where getting the plan right upfront saves hours of rework. Redesigning a system from scratch? Ultra think is the correct choice.

Permissions live in .claude/settings.json at the project level or globally. Use allowTools and disallowTools to specify exactly what Claude can touch. For production codebases, lock down destructive operations explicitly. For personal projects, loosen up for speed. Claude's default scope is the folder you launched it in — nothing outside that path is accessible without explicit permission. MCP servers configured in .claude/mcp.json extend Claude's reach further: query databases, interact with Jira, pull Figma designs, all from the same terminal session.

Hooks, sub-agents, custom slash commands, and MCP together turn Claude Code from a single tool into team infrastructure. The specific next step today: install Claude Code via Anthropic's official installer, run claude in a project you know well, and give it one bounded task — add a TypeScript test suite — before you hand it anything critical.
