Search engines and AI answers need HTML text, not only a poster image. Use this quick reference, then unlock the full printable cheatsheet below.

Project setup

CLAUDE.md — project commands, conventions, and constraints for every session.
/init — generate a starter CLAUDE.md for the repo.
/memory — edit memory files and manage auto-memory.
/permissions — set allow, ask, and deny tool rules.
/doctor — diagnose install, config, and health issues.
/mcp — connect, enable, disable, and auth MCP servers.
/add-dir — grant file access to another working directory.

During a task

/plan — enter plan mode before a large change.
/model — switch model and default effort level.
/effort — set reasoning effort from low through max.
/context — see what is filling the context window.
/compact — summarize history to free context space.
/btw — ask a side question without adding history.
/diff — review uncommitted and per-turn diffs.

Parallel work and review

/tasks, /background, /batch, /fork, /branch, /agents — manage parallel and background work.
/code-review, /review, /security-review — review diffs and PRs before you ship.
/clear, /resume, /rewind — reset, resume, or roll back a session.
/skills, /hooks, /plugin — extend Claude Code with skills, hooks, and plugins.

Core practices on the poster

Be specific: name files, expected behavior, and acceptance checks.
Take small verified steps: one logical change, then run checks and review the diff.
Use version control so Claude can inspect history and roll back.
Plan before big edits; tighten permissions for destructive commands.
RED / GREEN TDD: write a failing test, make it pass, then refactor.

For install and first-run config, read the Claude Code setup guide. For day-to-day workflows, read Claude Code best practices and Anthropic's official best practices.
