Claude Code runs in your terminal, reads your repository and changes files across it without you opening a single one. That is the point, and it is also how a lot of code ships that no human has read.
I am the human who reads it. You get a ranked list of what to fix, in plain English, each with a fix prompt you can paste straight back into Claude Code.
1Line 7: If Stripe rejects the change, the customer still sees a success message, the plan never updates and nothing retries; the only record is a log line nobody reads.
Common problems in Claude Code apps
Not every app has all of these. The report tells you which ones yours has, where, and what to do about each.
Critical
A .env file in the commit history
If .env was not ignored from the first commit, an agent running git add -A commits it along with everything else, and adding it to .gitignore afterwards does not remove it from history. I check every commit and list the keys you need to rotate.
High
Errors caught and thrown away
try/catch blocks that log and carry on, or return null, so the task finishes without a red error in the terminal. The payment that failed looks exactly like the one that succeeded. I trace each one to what it hides.
High
Packages that do not exist, or do not do that
The agent is confident about package names and method signatures from memory. Some are outdated, some never existed, and a package name the model made up is one anyone can register on npm. I check every import against the registry and the installed version.
Medium
Abstractions built for a future that is not coming
Repository classes, event buses and plugin systems wrapped around one table and one caller. Every layer is another place for a bug to hide and another thing the next session has to understand. I say what to remove.
Medium
Tests changed to match the bug
When a test fails, an agent told to make it pass will sometimes change the assertion instead of the code. I compare what the tests claim with what the product is supposed to do, and tell you which ones to trust.
Medium
N+1 queries behind clean-looking code
A loop that calls prisma.user.findUnique for every row works fine against a development database with ten rows. I find each one and give you the include, the join or the single query that replaces it.
Treatment plan
How it works
1
Book a check-up
Choose a tier and tell me where to send the report. Add your app's address if it is live. Two minutes, no sales call.
2
Show me your code
Pay by card, then give me read-only access to your code on GitHub (you paste in a key I send you) and let me into your app with test accounts. Never done that? I send you step-by-step instructions for your tool. I measure your app and confirm it fits before I start.
3
Get your diagnosis
Ready to launch, or not yet. Problems ranked, critical ones proven on your live app, each with a prescription for your AI tool. A PDF by email, then 7 to 30 days of questions by email.
4
Fix it, then a free follow-up
Fix the problems yourself, with your AI, or let me do it with the Fix Pack. Tell me within 30 days and I check once more that they are really gone.
No idea how big your app is? That’s normal, and you never have to count anything. Book the review you want; I measure your app before I start and tell you. If it doesn’t fit, you choose: upgrade, narrow it down, or a full refund. “Lines of your code” means the code you and your AI wrote, not the packages and UI kit your tool installed; many apps built with Lovable, Bolt or v0 fit the Safety Scan.
Start small, upgrade later. The Safety Scan’s price counts in full toward a Launch Review or Fix Pack for the same app within 30 days of your report.
Why this price? Software does the first pass, so you pay for the part only a person can do: checking every finding in your code, proving the critical ones and deciding what matters for your app. I take at most 3 Safety Scans and 2 Launch Reviews (or one Fix Pack) a week; if this week is full, yours starts the next.
Prices in US dollars, paid once, no sales call and no surprise invoice: anything extra is your choice, told to you before I start. The clock starts when I can see your code. Reports arrive as a PDF by email, in English, or German if you prefer.
Need a few things fixed after a scan? I fix by the hour at $199, three hours minimum, with the list agreed before I start.
Bigger than 50k lines, or a real mess? Rescue jobs are quoted, from $3,000, no obligation. Email me.
Not for you if
you have a team of engineers who already review each other’s code,
your app’s backend isn’t JavaScript or TypeScript (Python Replit apps, for example), or it is over 100k lines,
you handle regulated data (health records, banking, children), or need a pentest, certificate or compliance sign-off. Taking card payments through Stripe is fine.
A review lowers your risk a lot. It can’t guarantee that your app is secure, and nobody honest will say otherwise.
Claude Code questions
How do I share code written with Claude Code?
Claude Code works on a local repository, so push it to GitHub (or GitLab or Bitbucket) and give me read-only access (I send you a key to paste in; it takes a minute). If you have asked the agent to commit and push for you, that is probably already done.
Can I apply the fixes with Claude Code?
Yes. Each finding comes with a fix prompt that names the files and the change, written so an agent can act on it without guessing. Paste it into Claude Code, review the diff, and run the tests before you commit.
Will you look at my CLAUDE.md?
Yes, if you have one. The report ends with a short list of rules for your project, so that later sessions do not reintroduce the same findings. Most of them belong in CLAUDE.md.
Why not just ask my AI to review it?
Do, and I will even give you the prompt. You will get a long list. What your AI cannot do is tell you which items are real, prove them against your live app, see your database and hosting settings, or check that its own fixes worked. If you cannot read code, that is the part you cannot do yourself either. It is what you pay me for.
I'm not a developer. Is this for me?
Yes, that is exactly who it is for. If you built an app with AI and cannot tell whether the code is any good, I check it and explain what matters in plain English. You never need to understand the code to act on the report: every problem comes with a prompt you paste into your AI tool. And you do not need to know what to ask. The report answers the questions you would have asked if you knew how.
How do I show you my code?
Most AI builders can push your app to GitHub, a free site that stores code. You give me read-only access by pasting a key I send you into your repository settings, which means I can look but not change anything. Never done it? After you book, I send you step-by-step instructions for your tool. A zip file works too. When the report is delivered, remove my access again; I remind you.
Is my code safe with you?
Every booking comes with an NDA, automatically. I never sell, publish or pass on your code. The only other party that sees it is the AI provider that helps with the first pass, under terms that do not allow it to train on your code. I never need your passwords or your live database, and I delete my copy within 7 days of delivering the final report.
From $149 for the first 10 customers (10 left). Ready within 2 business days. If the Safety Scan finds no problem rated medium or worse, you pay nothing.
