Claude Code Ten Commands You Can Use Every Day
The slash commands that actually matter, in the order you'll need them. 1. /init First thing in any new project. Creates a CLAUDE.md file where you define how your project works, what conventions to follow, what to avoid. Without this, you're re-explaining your codebase every session. With it, Claude opens the session already oriented to your codebase. 2. /compact (full disclosure, I never use this one.) Your context window is finite. When a session runs long and context quality degrades, /compact compresses everything down to the essential points and frees up space. Run this proactively before starting a new chunk of work in the same session. 3. /clear Full reset. Wipes the conversation entirely. Use it when you're switching to a completely different task and don't want bleed from the previous conversation affecting results. 4. /cost Shows your token usage and spend for the session. I check this after long sessions to understand what's actually expensive. Helps you spot when a conversation has ballooned and you should /compact or start fresh. 5. /doctor Diagnoses your Claude Code setup. Checks your config, API keys, MCP servers, permissions. When something isn't working and you can't figure out why, run this first. Saves you from chasing config problems that aren't actually code problems. 6. /memory Between sessions, Claude Code retains what you've told it. /memory lets you view, add, or remove that stored context. Build it up over time so you're not starting from scratch every conversation. 7. /config Opens your settings. Permission modes, model preferences, allowed tools. The controls that determine how Claude Code behaves at a system level. 8. /review Runs a code review on your current changes. Point it at a PR or your working diff and Claude walks through it like a reviewer. Catches things fast. 9. /resume Pick up where you left off. Shows your recent sessions and lets you jump back into any of them with full context. I use this constantly when I close a terminal and come back the next day.
