You're Only Using 20% of Claude Code - Here's How to Unlock the Rest

Most devs are underutilizing Claude Code. These 5 advanced strategies will turn it into your most powerful engineering teammate

A month ago, I made the switch from Cursor to Claude Code. At first, it felt like a lateral move — different UI, same concept. But once I fully immersed myself in the Claude Code ecosystem, something clicked: most developers are only tapping into a fraction of what this tool can actually do.

After a few weeks of experimenting, refining, and building, I realized I had moved from "This is cool" to "I can't code without this." So I’m sharing five high-leverage tactics that helped me get there. These aren’t abstract ideas — these are real-world strategies I use daily.

Even if you consider yourself a power user, I’d bet there’s at least one thing here that’ll raise your Claude game.

1. Most People Aren’t Using MCPs Properly (Or At All)

If you’re not leaning into Model Context Protocols (MCPs), you’re essentially throttling a Formula 1 engine to 20 mph.

These are the five that redefined my workflow:

• Context7 – Essential. It dynamically pulls in documentation on demand, eliminating the need to hunt down docs or hope Claude remembers obscure API details.

• Effect Docs – I use the Effect library, which most models struggle with. This MCP bridges that gap by injecting knowledge that isn’t in Claude’s native dataset. If you use niche tech, find or build an MCP for it.

• Postgres – Total game-changer. I run queries, insert test data, and debug schemas — all without leaving my coding flow. There are MCPs for every major database: MySQL, Mongo, etc.

• Sequential Thinking – My intro to MCPs. It’s less critical now, but still useful for tackling complex, multi-step problems methodically.

• Test Master AI – Amazing when you’re rolling out something big that spans frontend, backend, and test coverage. Not for everyday use, but indispensable when the stakes are high.

One from the community: Consult7, which feeds your entire codebase into LLMs with massive context windows (like Gemini). I haven’t fully tested it, but the potential is huge. Props to @prof-stefan on YouTube for the tip.

2. Stop Skipping the Init Command — Seriously

Most complaints about Claude Code (“It doesn’t get my style,” “It keeps forgetting context”) stem from skipping the one thing that actually solves that: the /init command.

Run it. Set up a proper claude.md. This file becomes the instruction manual for your AI assistant.

Here’s a snippet from mine:

markdown

- Use IDE diagnostics to detect and fix issues - Reference prompt-engineering-playbook.md when refining prompts - Confirm test coverage after each implementation

I even link to my prompt engineering playbook, so when I ask Claude to “improve this prompt,” it doesn’t improvise — it applies strategies I trust.

Think of claude.md like onboarding documentation for a new teammate. Because that’s exactly what it is.

3. Code Less. Plan More.

This one feature has almost made Sequential Thinking and Test Master obsolete for me: Planning Mode.

Claude Code doesn’t just outline tasks — it understands your codebase, maps out dependencies, and creates a detailed roadmap for you to execute. The process looks like this:

1. Describe what you want

2. Let Claude generate a structured plan

3. Review and tweak it

4. Implement with total clarity

That extra minute or two of planning? It’s saving me tons of refactoring and rework down the line.

4. The Max Plan Is a No-Brainer (And Here’s Why)

At $100/month, Claude’s Max plan isn’t cheap — but it might be the best investment I’ve made in my workflow.

Why? Unlimited usage. No token juggling. No worrying about hitting limits mid-project.

I saw a developer burn through $6,000 in API credits in one month using standard plans. That’s not a typo. Just imagine the efficiency lost when you’re constantly watching usage stats.

With Max, I get uninterrupted access. Claude becomes a true collaborator, not a meter-watching assistant.

Even if you’re not ready for Max, start with Pro or credits. But once you get a taste of that freedom, you won’t go back.

5. The IDE Plugin Feels Like Cheating (In a Good Way)

If you haven’t installed the Claude Code IDE extension yet, you’re missing out.

When integrated with your IDE, Claude doesn’t just guess what’s wrong — it sees the red squiggly lines and diagnostics. That changes everything:

• It catches type errors in real-time

• It self-corrects syntax issues

• It loops through fixes until the code actually works

And yes — you should reference this behavior explicitly in your claude.md file:

markdown

- Always use IDE diagnostics to validate and correct code

With this setup, Claude isn’t just generating code — it’s shipping working code that compiles and passes tests.

Final Thoughts

These aren’t just tricks — they’re the difference between using Claude Code and owning it.

I’ve seen people struggle with simple tasks using the same tool I’m using to ship complete features. The gap isn’t the tool — it’s the process.

If you’re serious about AI-assisted development, here’s the move:

1. Learn your MCPs

2. Set up your claude.md

3. Always plan before coding

4. Upgrade to the Max plan (if it makes sense)

5. Sync with your IDE

Adopt these five steps, and I promise — you’ll wonder how you ever coded without them.
