Claude Code

Plan Mode

• Shift + tab + tab
• Use “opus” for planning and Sonnet for everything else, /model

Multi Agent Parallel Tasks

• Run 15 task agents in parallel, give each of them a unique extreme personality and ask them to review the code from their own unique lens
• For more complex multi-agent workloads: https://github.com/parruda/claude-swarm

Clear/Compact Existing Context

• /clear, this will erase everything. Prefer /compact for summarizing the chat.

MCP Server

• https://github.com/oraios/serena Enables better find and replace capabilities that work at the symbol level
• Context7 for up-to-date docs without need for web crawling
• Playwright for UI testing

Types First

• Build the business model first and then the code. This can even be a DB schema or zod schemas.

Adding Tons of Text as Context

• Don’t paste a lot of text into Claude Code terminal. Instead, create a new file, add the text there, and add it as context to Claude Code using the @ tag.

Pasting Images

• CTRL + V

Continue to the Last Session

• claude -c

Initializing CLAUDE.md

• /init

Check Usage

• npx ccusage
• /cost

Custom Commands

• For repeated workflows—debugging loops, log analysis, etc.—store prompt templates in Markdown files within the .claude/commands folder. These become available through the slash commands menu when you type /.. You can check these commands into git to make them available for the rest of your team.
• Use argument-hint and description in header.

Thinking Modes

• “Think” < “think hard” < “think harder” < “ultrathink”
• 4k < 8k < 16k < 32k TOKENS

Claude Code Headless Mode

• Example: npm audit —json | claude -p ‘Order the vulnerabilities by the most critical fixes needed’ > vulnerabilties.md

Check Past Sessions

• claude —resume

StatusLine

• Example: /statusline add Model | Git Branch | Tokens | Directory
• Customize the line below the chat input with: Model | Git Branch | Tokens | Directory

MCP

• Use a .mcp.json file to have MCP servers per project.

YOLO Mode

• Open Claude with —dangerous-skip-permissions

Rewind

• Undo last piece of work: /rewind OR ESC + ESC

Look for Text in Conversation

• Use Ctrl + R like in any other terminal

Add to Claude.MD to make messages less bloated with useless info

• "In all interactions and commit messages, be extremely concise and sacrifice on grammar for the sake of concision."
