Claude Code is deceptively simple on the surface. You type a prompt, Claude writes code, you accept or reject. But underneath that simplicity is a tool with serious depth — and most developers are using maybe 20% of it.
I've been using Claude Code daily since it launched. Here are the tips that actually changed my workflow, not the obvious stuff you'd find in the docs.
1. Use Hooks to Automate the Boring Parts
Hooks are Claude Code's most underused feature. They let you run scripts automatically before or after specific events — pre-commit checks, post-edit formatting, notification triggers.
Example: Auto-format on every file edit — Set up a hook in your .claude/settings.json that runs Prettier after Claude edits any file. No more "can you format that?" prompts.
Example: Pre-commit security scan — Hook a lightweight secret scanner into the pre-commit flow. I've caught accidental key leaks three times with this.
Example: Notification on long tasks — If a task takes more than 60 seconds, hook a system notification. Walk away, get pinged when it's done.
2. Permission Modes Are a Spectrum
Most people either run Claude Code with full permissions or default restrictive. Neither is optimal.
The sweet spot: plan mode for architecture, then switch to full permissions for implementation. You don't need to approve every mkdir during implementation. But you absolutely want to review the database schema before Claude creates 15 migration files.
3. Model Selection Is a Power Move
Haiku — Fast, cheap, good for repetitive tasks. Renaming variables, generating boilerplate, writing test fixtures.
Sonnet — The daily driver. Feature implementation, debugging, code review. 90% of your work.
Opus — The architect. System design, complex refactors, debugging the really weird stuff.
The workflow: Start with Opus to plan. Switch to Sonnet for implementation. Drop to Haiku for cleanup. Three models, one feature, optimal cost and quality.
4. Context Management Is Everything
Signs your context is full: Claude repeats questions, suggests approaches you rejected, code quality drops, it forgets project structure.
How to manage it:
- Use
CLAUDE.mdfiles aggressively for persistent context - Start new conversations for new tasks
- Use compact mode when context gets long
- Front-load important information in prompts
5. The Slash Command Ecosystem
Custom slash commands let you build reusable workflows. Instead of typing the same multi-step prompt, package it as a command.
Examples I use daily: /review for code review, /test for test generation, /deploy for the full pipeline with safety checks.
6. The .claude Directory Is Your Config Goldmine
Most developers have a .claude directory and never look inside it. It contains settings.json, custom commands, agent definitions, and project rules. Invest 30 minutes setting it up — it's the difference between Claude Code being a generic tool and being YOUR tool.
7. Multi-File Edits: Think in Systems
Instead of: "Add a created_at field to the User model"
Try: "Add creation timestamp tracking to users. Update the model, migration, API serializer, and tests."
Claude Code understands dependency chains. Let it work at the system level.
8. Git Integration Is Smarter Than You Think
"What changed since the last commit?" — quick diff review.
"Write a commit message" — contextual, conventional-commit-formatted messages.
"Is this branch ready to merge?" — self-review against project standards.
9. Error Recovery Is a Skill
Don't delete everything and start over. Tell Claude what went wrong and why. Specific error feedback produces better corrections than vague "that's wrong, try again."
10. Make It Yours
The biggest tip: Claude Code is a platform, not just a tool. Your hooks, your commands, your rules, your model preferences — customize it. Spend a weekend setting it up properly. You'll get that time back in the first week.
