Advent of Claude: 31 Days of Claude Code

Summary

Ado Kukic compiled 31 Claude Code tips shared throughout December into a single reference. The guide progresses from basics like /init and session management to advanced patterns including browser automation, plugins, and the Agent SDK.

Key Concepts

• Project onboarding: Use /init to generate a CLAUDE.md file that helps Claude understand your codebase
• Essential shortcuts: ! prefix for instant bash execution, Escape to rewind, Ctrl+R for reverse search
• Session continuity: Resume work with --continue or --resume, use named sessions for project context
• Thinking modes: Extended thinking with ultrathink and megathink for complex reasoning
• Plan mode: Structured approach for multi-step implementations
• Headless automation: Run Claude in CI/CD pipelines with --print flag
• Browser integration: Chrome extension enables web interaction through MCP tools
• Extensibility: Skills package reusable prompts, plugins add community functionality, SDK enables custom agents

Core Philosophy

The guide emphasizes that Claude Code's value comes from user control. AI works as a lever—developers who structure prompts strategically and use plan mode find optimal leverage points. Collaboration beats automation.
