Advanced Claude Code Usage: Tips and Tricks for Power Users

Beyond the Basics

Claude Code is a terminal-native coding agent that pairs the Claude model with deep filesystem, shell, and tool integrations. Once you have gotten comfortable with the basics, a number of advanced techniques can transform it from a smart autocomplete into a tireless collaborator that handles entire features end to end.

1. Master the CLAUDE.md File

Drop a CLAUDE.md file at the root of your repository and Claude Code will load it automatically at the start of every session. Use it to capture project conventions, common commands, directory layouts, and any sharp edges in the codebase. A well-tuned CLAUDE.md is the highest-leverage configuration you can make. You can also use nested CLAUDE.md files in sub-directories for context-specific instructions.

2. Use Custom Slash Commands

Place markdown files in .claude/commands/ and they become slash commands available across the project. A /review-pr command that runs your tests, checks linting, and writes a structured review summary saves enormous time once it is dialed in. Share these commands with your team via version control.

3. Spawn Sub-Agents for Parallel Work

Sub-agents let you delegate scoped tasks to a fresh Claude instance with its own context window. Define them in .claude/agents/ with a clear system prompt and tool whitelist. A code-reviewer agent that only reads files, or a test-runner agent that only executes tests, keeps your main session focused.

4. Trigger Extended Thinking

For tricky architecture or debugging problems, ask Claude to think before acting. The keywords think, think hard, think harder, and ultrathink allocate progressively more reasoning budget. Reserve the higher levels for problems that genuinely require deeper analysis.

5. Plug In MCP Servers

The Model Context Protocol lets you connect Claude to GitHub, Linear, Postgres, Sentry, browser automation, and many more tools. Add servers with claude mcp add and reference them from within your sessions. This is how you turn Claude Code into a true integrated workflow tool rather than just a code generator.

6. Build Headless Pipelines

Use claude -p "..." in scripts and CI to run automation jobs. Combine with --output-format json for structured output, and stream JSON to chain multiple Claude invocations. Pair with GitHub Actions to auto-triage issues or draft PR descriptions.

7. Tame Long Sessions with /compact

When the context gets crowded, run /compact to summarize the conversation in place. Use the optional argument to focus the summary on what matters: /compact focus on the auth refactor decisions. Combine with /clear for hard resets between unrelated tasks.

8. Use Plan Mode Liberally

Plan mode (Shift+Tab) lets Claude read and reason about the code without making any edits. It is perfect for impact analysis before touching legacy code, or for getting a high-level approach approved before implementation.

9. Hooks for Guardrails

Hooks let you run shell commands at specific lifecycle events, such as before a file write or after a tool call. Use them to auto-format code, block edits to protected paths, or send notifications when long-running tasks finish.

10. Image Pasting

Paste screenshots directly into the terminal session. Claude Code reads them with its vision capabilities, making it easy to debug UI issues, transcribe diagrams, or implement a design from a mockup.

Putting It All Together

The power users do not rely on a single trick. They combine a tight CLAUDE.md, a library of slash commands, well-scoped sub-agents, and MCP integrations into a personalized development environment. Invest the time once, reap the gains every day.
