If you're typing prompts and copy-pasting code outputs, you've been using Claude Code wrong this whole time. A DEV.to breakdown from developer lizziepika exposes the slash command layer built into Anthropic's CLI tool โ€” functionality that's right there in the terminal but remains criminally underused by most developers.

Session Management Commands

Three commands handle session state like a pro: /resume reconnects you to a previous coding session after closing your terminal, preserving all context so nothing gets lost overnight. The /branch command is where things get interesting โ€” it forks your conversation into a separate branch without affecting your main working context, letting you safely experiment with risky refactors or try alternative approaches. And when Claude starts going in circles due to bloated context, /clear wipes the slate clean for a fresh start.

Pre-Implementation Workflow

Before writing any code, these commands set you up properly: Running /init in a new project generates your CLAUDE.md file โ€” the configuration that teaches Claude about your tech stack, coding conventions, and project structure. Think of it as mandatory onboarding for every codebase. The /plan command forces a written implementation plan before touching any files, which leads to noticeably better output on complex features by catching scope issues early. And /memory gives you read/write access to what Claude remembers across sessions โ€” treat this like a shared notepad that needs regular maintenance.

Active Development Commands

During active coding work, three commands prove their worth: The /diff command launches an interactive viewer showing all changes made in the current session with toggleable views between full git-style diffs and per-turn modifications. This is your sanity check before committing โ€” exactly what changed since your last save. When conversation history grows unwieldy, /compact compresses context while preserving critical decisions, keeping responses fast without losing the thread. And for anything touching authentication, payments, APIs, or user data, running /security-review catches vulnerabilities before they reach production.

Key Takeaways

  • Session commands (/resume, /branch, /clear) handle terminal chaos and experimentation safely
  • Pre-coding setup (/init, /plan, /memory) determines long-term quality of AI collaboration
  • Development commands (/diff, /compact, /security-review) provide visibility and catch mistakes early

The Bottom Line

These aren't hidden tricks or hacks โ€” they're first-class tools that ship with Claude Code but stay invisible because there's no onboarding. The workflow becomes clear once you chain them: start fresh projects with /init, use /plan before diving in, keep sessions lean with /compact, verify changes with /diff, and audit sensitive code with /security-review. That's not a chatbot โ€” that's closer to having a senior dev who handles the tedious context management so you can focus on solving actual problems.
