Claude Code is incredible at coding. But let's be honest — most of us use it the same way: type a question, get an answer, move on.
You are leaving 80% of its capability on the table.
I spent weeks building a collection of 50 specific, battle-tested prompts that turn Claude Code into specialized tools:
- A code reviewer that catches SQL injection, memory leaks, and race conditions
- A bug investigator that traces root causes instead of guessing
- A performance auditor that finds bottlenecks in your stack
- A refactoring planner that shows you exactly which files to touch (in what order)
- A dependency auditor that flags security risks before they reach production
The Problem
Most developers use Claude Code with ad-hoc prompts. "Review this code" — and you get a shallow pass. "Debug this" — and you get random guesses.
The secret is specificity. A prompt like:
You are a senior security engineer. Review this diff for:
1. SQL injection in string interpolation
2. XSS in unescaped template variables
3. Memory leaks from unclosed event listeners
4. Race conditions in async operations
For each finding, provide: severity (🔴/🟡/🟢), file:line, exploit scenario, and exact fix code.
This is not the same as "review this code." The difference is night and day.
What I Built
I compiled 50 such prompts into single-file markdown documents. Each one is a specific tool:
| # | Skill | What It Does |
|---|---|---|
| 1 | Auto Commit Messages | Generates conventional commits from staged changes |
| 2 | Code Review Assistant | Catches bugs, security holes, design issues |
| 3 | Project Context Builder | Understands any codebase in 2 minutes |
| 4 | Test Generator | Creates comprehensive test suites |
| 5 | Bug Investigator | Root cause analysis, not random fixes |
| 6 | API Documentation | Generates docs from source code |
| 7 | Database Migrations | Safe schema change planning |
| 8 | Refactoring Planner | Incremental, reversible refactoring |
| 9 | Dependency Audit | Security + license + bloat analysis |
| 10 | Performance Audit | Find bottlenecks and config issues |
| ... and 40 more covering CI/CD, Docker, security, monitoring, and production ops |
How to Use
git clone https://github.com/zhirenhun-stack/claude-code-skills.git
claude -p "$(cat skills/02-code-review.md)" -p "$(git diff main)"
Why Free?
I believe these prompts should be accessible to everyone who codes. The free GitHub repo has 10 prompts. The full pack of 50 is pay-what-you-want ($0 minimum) — you decide.
If you find even 2-3 prompts that save you time, share them with a teammate. That is the only "payment" I ask for.
Real Example: Dependency Audit
Yesterday I ran the Dependency Audit on a 3-year-old Node.js project:
🔴 HIGH — CVE-2024-XXXX in lodash@4.17.15
→ Server-side prototype pollution via crafted JSON
→ Fix: npm install lodash@4.17.21
🟡 MEDIUM — Leftpad-style pattern in 3 dependencies
→ These packages have 1 maintainer and 0 test coverage
→ Consider inlining or replacing
🟢 LOW — 8 unused devDependencies
→ Removed: node-sass, gulp, coffeescript (21 MB saved)
It took 10 seconds. It would have taken 30 minutes to audit manually.

Drop a comment if there is a specific skill you want me to add. I am actively maintaining this collection.
P.S. If this saves you even one debugging session, star the repo. It helps others find it.
