After months of daily use across dozens of projects, we’ve accumulated a library of Claude Code techniques that dramatically improve output quality and speed. These aren’t in the getting-started guides — they’re the tricks you learn from repetition and experimentation.
Here are 15 tips that have made the biggest difference in our workflow at Markana Media.
Prompt Engineering Tips
1. Lead with the outcome, not the method. “Add password reset functionality with email verification” works better than “create a new file called reset-password.js and add a function that generates a token.” Claude Code is better at planning the implementation when you describe what you want, not how to build it.
2. Reference existing code as examples. “Build the settings page following the same pattern as the profile page” gives Claude Code a concrete reference. It reads the referenced file and mirrors the conventions — component structure, styling approach, state management pattern, everything.
3. Use the word “plan” for complex tasks. Starting your prompt with “Plan how to…” or “Before writing code, outline your approach for…” activates Claude Code’s planning mode. It shows you the full implementation strategy before touching any files, letting you course-correct early.
4. Give constraints upfront. “Build this without adding any new dependencies” or “keep this under 100 lines” or “use the existing database schema without migrations” prevents Claude Code from over-engineering the solution. Constraints produce better code.
5. Pipe in context when possible. Claude Code’s CLI follows Unix conventions. You can pipe in error logs, test output, or file contents: cat error.log | claude -p "what's causing these failures?" This gives it precise context without you having to copy-paste.
CLAUDE.md Power Moves
6. Layer your CLAUDE.md files. Claude Code reads CLAUDE.md files at three levels: the project root, subdirectories, and your user home (~/.claude/CLAUDE.md). Use the project root for shared conventions, subdirectory files for module-specific rules, and user-level for personal preferences. All three merge together in every session.
7. Include negative instructions. “Never use inline styles” or “Don’t import from legacy/ — those modules are deprecated” prevents common mistakes. Negative instructions are just as valuable as positive ones in CLAUDE.md.
8. Document your deployment pipeline. Adding “After editing theme files, commit and push to main. The GitHub Action will auto-deploy.” to your CLAUDE.md means Claude Code handles the entire deploy flow without you having to remind it every time.
Workflow Optimization
9. Use /compact during long sessions. Claude Code has a context window limit. During long sessions (multiple features, debugging chains, refactoring), the context fills up and quality can degrade. The /compact command summarizes the conversation and frees up space, keeping Claude Code sharp for the rest of the session.
10. Chain tasks with “then.” “Write the API endpoint, then write tests for it, then run the tests and fix any failures.” Claude Code executes these sequentially, and each step has full context from the previous ones. This is more reliable than giving three separate prompts because it maintains continuity.
11. Use sub-agents for large refactors. When you need to update 20 files with a consistent change, Claude Code can spawn multiple sub-agents that work in parallel. “Update all API endpoints to use the new error handling pattern — use sub-agents to work in parallel.” This turns a 30-minute task into a 5-minute one.
12. Run Claude Code headlessly in scripts. The claude -p "your prompt" flag runs a single prompt without an interactive session. Use this in shell scripts, CI/CD pipelines, or scheduled tasks. We use it to auto-generate release notes, run nightly code quality checks, and update documentation after merges.
Advanced Techniques
13. Create custom slash commands. Custom skills let you package complex workflows into simple commands. Create a /seo-audit command that runs your full SEO checklist on a page, or a /deploy-staging that builds, tests, and deploys to your staging environment. These live in your project’s .claude/skills/ directory and are available to the whole team.
14. Use hooks for automatic quality gates. Hooks run shell commands before or after Claude Code actions. Set up a hook that runs your linter after every file edit, formats code with Prettier after every save, or runs your test suite before every commit. This catches issues in real time instead of during code review.
15. Connect MCP servers for full workflow coverage. The Model Context Protocol lets Claude Code interact with external services. Connect your project management tool so Claude Code can read tickets and update status. Connect your CMS so it can publish content. Connect your analytics so it can pull performance data into its reasoning. The more context Claude Code has, the better its output.
Bonus: Debugging Tips
Claude Code is one of the best debugging tools available when you know how to use it:
Paste the full error, not a summary. Copy the complete stack trace, error message, and any relevant log output. Claude Code extracts more signal from the raw error than from your interpretation of it.
Ask “why” before “fix.” “Why is this test failing?” gives you understanding before a patch. “Fix this test” might give you a band-aid that hides a deeper issue. Understanding the root cause leads to better fixes.
Use git diff as context. “Here are the changes I made since yesterday — why did the login page break?” combined with git diff HEAD~1 | claude -p "..." gives Claude Code the exact delta that caused the issue.
Start Using These Today
You don’t need to implement all 15 tips at once. Start with the ones that match your current pain points. If you’re spending too much time on repetitive tasks, focus on custom commands and hooks. If your output quality is inconsistent, invest time in your CLAUDE.md file. If your sessions are slow, learn to use /compact and sub-agents.
The compounding effect of these techniques is significant. Each one saves minutes per session, and when you stack them, you’re looking at hours saved per week. That’s time you can redirect to strategy, client relationships, or building new things.
