25 Claude Code Tips and Tricks for Power Users

Most developers use 20% of Claude Code's capabilities. The other 80% is sitting there, unused — waiting to make you dramatically faster. These 25 tips are what separate casual users from power users. Work through them once and you'll never go back.

Setup

1. Configure CLAUDE.md for Every Project

CLAUDE.md is the first file Claude reads in any project. Use it to define your stack, conventions, and preferences — so you never have to repeat yourself.

# Project: E-commerce API
Stack: Node.js, TypeScript, PostgreSQL, Prisma, Express
Test runner: Vitest
Style: Prettier with 2-space indent, single quotes
Conventions:
- Use async/await, never callbacks
- All API routes need input validation via Zod
- Errors go through the centralized error handler

With a good CLAUDE.md, Claude knows your conventions from the first message in every session.

2. Use Memory to Persist Context

Claude's memory system remembers things across sessions. Tell it important things once:

/memory "We use Railway for deployment. Backend is at api.myapp.com.
Frontend is at myapp.com. Staging is at staging.myapp.com."

Now you never have to explain your deployment setup again.

3. Set a Default Persona in CLAUDE.md

Add this to your CLAUDE.md:

When I don't specify otherwise, act as a senior TypeScript engineer
who values simplicity, correctness, and maintainability over cleverness.

This shapes every response without you having to ask.

4. Create Project-Specific Slash Commands

Define custom slash commands in your project's .claude/commands/ directory:

# .claude/commands/new-component.md
Create a new React component with:
- TypeScript props interface
- Default export
- Basic unit test file
- Storybook story

Component name: $ARGUMENTS

Now /new-component Button creates all four files.

5. Use .claudeignore to Keep Context Clean

Like .gitignore, .claudeignore tells Claude which files to skip. Add build output, node_modules, generated files:

node_modules/
dist/
.next/
*.generated.ts
coverage/

Smaller context = faster responses = more focused answers.

Navigation

6. Master @ File References

Instead of "the file at src/components/auth/LoginForm.tsx", type @src/components/auth/LoginForm.tsx. Claude gets the exact file contents with zero copy-paste.

Chain multiple references: "Compare @src/auth/v1.ts with @src/auth/v2.ts and explain the differences."

7. Use # to Reference Memories Inline

If you've saved memories, reference them with #:

Add rate limiting to the API endpoints as specified in #deployment-config

8. Learn the Essential Keyboard Shortcuts

• Ctrl+K (or Cmd+K) — clear context, start fresh
• Ctrl+R — search conversation history
• Ctrl+L — jump to last message
• Tab — accept autocomplete in the input
• ↑/↓ — navigate message history

9. Use Slash Commands for Repetitive Tasks

Built-in slash commands you should know:

• /review — code review mode
• /test — generate tests for current file
• /explain — explain the selected code
• /refactor — refactor with a description of goal
• /commit — generate a commit message from staged changes

10. Pin Important Files for Long Sessions

In long sessions, use @file references to keep critical files in context. When working on a feature, pin your main component, its types, and its test file — and reference them together:

Looking at @src/components/Checkout.tsx, @src/types/checkout.ts,
and @src/tests/checkout.test.ts — what's the best way to add
the discount code feature?

Workflow

11. Use Hooks for Automated Actions

Claude Code hooks run automatically on events. The most useful:

// .claude/hooks.json
{
  "PostToolUse": [
    {
      "matcher": "Edit",
      "hooks": [{ "type": "command", "command": "npx prettier --write $CLAUDE_FILE_PATHS" }]
    }
  ]
}

Now every file Claude edits is automatically formatted. No more formatting fixes after AI edits.

12. Run Parallel Agents for Independent Tasks

When you have multiple independent tasks, don't run them sequentially. Use subagents:

Spawn three parallel agents:
1. Agent 1: Write unit tests for src/services/auth.ts
2. Agent 2: Write unit tests for src/services/payment.ts
3. Agent 3: Write unit tests for src/services/email.ts
Report back when all three are done.

Three tasks done simultaneously — 3x faster than sequential.

13. Use Git Worktrees for Parallel Feature Development

Worktrees let you have multiple branches checked out simultaneously, perfect for running parallel Claude agents on different features:

git worktree add ../feature-payments feature/payments
git worktree add ../feature-auth feature/auth

Run one Claude session in each directory — independent context, no interference.

14. Create Reusable Prompt Templates

Save your best prompts as templates in .claude/templates/:

# .claude/templates/api-endpoint.md
Create a complete API endpoint for [RESOURCE]:
1. Route definition with proper HTTP method
2. Input validation with Zod
3. Service layer function
4. Database query (Prisma)
5. Error handling
6. Unit test
7. Integration test

Reference it: "Use @.claude/templates/api-endpoint.md for the orders endpoint."

15. Use the Undo Feature Aggressively

Claude Code has an undo system — if a change goes wrong, you can roll it back without manually reverting. Use this to make Claude more adventurous with refactors: "Try the more aggressive refactor — we can always undo."

Skills

16. Combine Skills for Complex Tasks

Skills stack. Combine them for compound expertise:

With both typescript-pro and react-expert active, refactor this
data-fetching component to use Server Components and proper TypeScript generics.

Two skills active = TypeScript expert + React expert in one response.

17. Trigger Skills with Context, Not Commands

Most skills activate automatically from context. You don't need to type "use typescript-pro skill." Just:

• Work in a .tsx file → react-expert activates
• Ask about Docker → devops-engineer activates
• Mention a bug → debugging-wizard activates

18. Use Custom Skill Triggers

You can define custom trigger phrases in your CLAUDE.md:

When I say "go full TypeScript", activate typescript-pro and enforce
strict mode, no `any`, proper generics everywhere.

Now "go full TypeScript" is a power mode command.

19. Chain Skills for Code Review + Fix

Review and fix in one prompt:

With code-reviewer active, review this PR and then, for each issue found,
immediately write the corrected code.

Review mode + fix mode in a single command.

20. Create Domain-Specific Skills for Your Team

Teams can create custom skills for their specific stack. A skill file for your team's conventions means every developer gets the same expert context:

# .claude/skills/our-stack.md
You are an expert in [Company]'s tech stack:
- Next.js 15 App Router
- Prisma with PostgreSQL
- Clerk for auth
- Vercel for deployment
Always follow our convention of [...]

Advanced

21. Use MCP Servers for External Data

Model Context Protocol (MCP) servers let Claude access external data sources directly. Connect your database, documentation, or internal tools:

// .claude/mcp.json
{
  "servers": {
    "postgres": {
      "command": "npx @modelcontextprotocol/server-postgres",
      "env": { "DATABASE_URL": "${DATABASE_URL}" }
    }
  }
}

Now Claude can query your actual database schema and write accurate queries without you describing the schema manually.

22. Build Subagent Workflows for Large Tasks

For tasks too big for one context window, break them into subagent chains:

Task: Migrate the entire codebase from JavaScript to TypeScript.
Phase 1: Analyze all files and create a migration plan
Phase 2: (For each file) Convert to TypeScript and add types
Phase 3: Run the full test suite and fix any type errors
Phase 4: Update documentation

Each phase is a separate agent call — the output of one feeds into the next.

23. Use --continue for Long-Running Tasks

When a task is cut off mid-way (context limit), use --continue to resume from exactly where it stopped. Claude maintains state between the interrupted and resumed sessions.

24. Pipe External Context into Claude

Shell integration means you can pipe real system data directly:

# Review the actual running logs
docker logs my-app | claude "identify any error patterns in these logs"

# Analyze real database query performance
psql -c "EXPLAIN ANALYZE SELECT ..." | claude "explain this query plan and suggest optimizations"

# Review PR diffs
gh pr diff 142 | claude "review this PR for security issues"

Real data + Claude = much better analysis than descriptions.

25. Measure and Iterate Your Workflow

Track which prompting patterns give you the best results. Keep a personal prompts.md of your best prompts:

# My best prompts

## Code review
"Review this code as a security engineer who just read the OWASP Top 10.
Flag every issue in order of severity, with the actual exploitable scenario for critical ones."

## Architecture decision
"I need to decide between [option A] and [option B].
Assume I'm building this for 10x scale from today.
Give me three arguments for each side, then your recommendation."

## Debugging
"I have this bug: [description]. Here's the code: [code].
Form three hypotheses about the root cause, ranked by probability.
Then test each one and tell me what you find."

The prompts that work become reusable tools.

The Compounding Effect

These tips work individually, but they compound. A developer who has set up CLAUDE.md, uses skills, has hooks configured, and knows how to spawn parallel agents isn't just 25 tips better — they're working in a fundamentally different way than someone running single-shot prompts.

The skills that enable many of these patterns are part of the SuperSkills library. 139 skills, every domain, one flat price.
