Claude Code — Everything You Need to Know

Claude Code is Anthropic's terminal-native AI coding agent. It runs directly in your shell, reads your entire codebase, plans multi-step engineering tasks, executes commands, edits files across projects, and commits changes — all autonomously. Unlike IDE copilots that suggest the next line, Claude Code operates as a full agentic system: you describe the goal, it figures out the plan and executes it.

How Claude Code Works

Claude Code connects to your project through three layers. First, CLAUDE.md files at your repository root define project-level instructions — coding standards, architecture decisions, build commands. Claude Code reads these automatically at session start, so it follows your team's conventions without repeated prompting.

Second, MCP servers extend Claude Code's reach beyond your filesystem. Through the Model Context Protocol, it connects to databases, APIs, monitoring dashboards, and documentation servers — anything your workflow touches.

Third, agent teams let Claude Code spawn parallel sub-agents, each working in an isolated git worktree. A lead agent coordinates the work, assigns tasks, and merges results. This makes large-scale refactoring across monorepos practical — not just possible, but fast.

Key Claude Code Features

Agent teams — spawn sub-agents that work in parallel across different parts of your codebase, each in its own git worktree.

Memory system — CLAUDE.md files for deliberate instructions, auto memory for emergent knowledge. Context persists across sessions.

Voice mode — speak coding instructions instead of typing them. Same tools, same agent loop, different input method.

Remote control — kick off tasks in terminal, monitor and steer from your phone.

Code review agents — multi-agent PR review that catches the bugs human reviewers miss at 3am.

Security scanning — point Claude Code at a codebase and let it hunt for vulnerabilities with full project context.

Headless mode — run Claude Code programmatically with -p for CI/CD pipelines, batch operations, and scripted workflows.

Skills & hooks — skills encode workflows as slash commands; hooks enforce deterministic guardrails over non-deterministic AI behavior.

/simplify & /batch — built-in skills for automated PR cleanup and multi-task execution.

Scheduled tasks — automate recurring prompts with /loop and cron integration.

Prompt stashing (Ctrl+S) — queue your next prompt while Claude is still working on the current one.

/btw side chains — ask a quick question mid-task without derailing Claude's current work.

Best Practices

Test-driven development is your best control mechanism. When you give Claude Code a failing test, it has an unambiguous target. When you let it freestyle without tests, you get plausible-looking code that may not do what you intended. The Red Green Refactor workflow shows how TDD turns Claude Code from a code generator into a reliable engineering tool.

Structure your knowledge before feeding it to Claude Code. The Superpowers project demonstrates how 15 well-crafted SKILL.md files can replace thousands of lines of prompt engineering. Combine this with Obsidian as a second brain and Claude Code gets access to your entire knowledge graph, not just the current project.

Choose the right extension mechanism. Most developers reach for MCP servers when a 10-line skill file would suffice. Read MCP vs CLI vs Skills before building anything. And for tasks that span hours, set up proper harnesses for long-running agents — initializer agents, progress files, and incremental sessions that survive context window limits.

Claude Code in Production

Claude Code isn't just for solo developers. Ramp, Shopify, Spotify, and other engineering organizations are deploying it across teams of hundreds, with structured onboarding, CLAUDE.md governance, and measurable productivity gains. The enterprise patterns that work — and the ones that don't — are covered in that deep dive.
