Vibe Coding (Guardrails)
Vibe coding, with guardrails so it ships.

The review loop that makes vibe coding viable.
Your team keeps shipping with Lovable, Cursor, Bolt, or whatever fits. We plug in as the senior engineer your repo has been missing.
Works with Lovable, Cursor, Bolt, Replit, Windsurf, or your own workflow.
02
Fix PRs, not just notes
When the fix is faster to ship than explain, we open the PR ourselves and tag you.
03
Auth + data safety audit
Server-side auth, tenant scoping, and input validation reviewed on day one.
04
Observability kit
Sentry, structured logs, at least one meaningful alert - so you know when things break.
05
Patterns doc
The 5–8 patterns we enforce in your repo, written down so AI tools can pick them up too.
06
Weekly risk summary
The top 3 risks we saw this week, the ones we fixed, the ones still open. No noise.
The process
How the guardrail engagement runs
- 01
Pick the blast radius
Define what can stay experimental and what must stay stable. Guardrails applied where they matter.
- 02
Plug into your PR flow
We review every merge against a 10-point checklist, with feedback inside 24 hours.
- 03
Fix notes or fix PRs
Small fixes come as PRs from us. Bigger ones come as actionable notes you can action yourselves.
- 04
Weekly hardening pass
One pass per week on risk items, observability gaps, and patterns to enforce going forward.

What a senior actually reviews
The 10 things AI gets almost right - and we fix before merge.
Vibe coding ships product. The quality gates below are what separate a demo from something you can put in front of a paying user.
Not hypothetical. Every item below is something we’ve caught in the last 30 days of PR review on AI-assisted code.
Inputs validated at the boundary
01Every external input (API, form, query) passes a schema check.
Caught:AI often returns a happy-path handler. We catch missing validation before merge.
Authorization enforced on the server
02No UI-only gating. Every data access runs through a policy.
Caught:Most common vibe-coded bug: UI hides buttons but API is wide open.
N+1 queries ruled out
03Each endpoint reviewed for query patterns that scale linearly with data.
Caught:AI loves inner loops that query inside a map. We inline-rewrite these.
Error states deliberate, not accidental
04Try/catch paths return user-actionable messages and telemetry.
Caught:Raw 500 errors make it to users. We replace them with typed, logged responses.
Secrets + env wired through a single source
05No hardcoded keys. All config goes through env or a secret manager.
Caught:AI will paste test keys or fake URLs. We prune before CI.
Dangerous migrations gated behind a plan
06Schema changes shipped with backfill + rollback + runbook.
Caught:Drop column, backfill-in-app, prod outage. Classic. Never shipped.
Tests cover the path that could break production
07Not 100% coverage - the 10% of paths that matter.
Caught:AI tests scaffolded code. We add the integration tests that AI won't.
Observability shipped with the feature
08Logs, metrics, and at least one alert for the new surface.
Caught:Shipping dark is how bugs live for weeks. We block merge without telemetry.
Accessibility not visibly broken
09Keyboard nav, color contrast, semantic HTML - baseline checks.
Caught:AI ships divs-as-buttons. We replace them before review.
Perf budget not regressed
10Key pages still inside the LCP / CLS / TTI budget after changes.
Caught:AI drops in a 400KB client dependency without thinking. We audit the diff.

What moves the number
- Merge volume
- High-throughput teams (20+ PRs/week) usually need the next tier up.
- Stack complexity
- Multi-tenant SaaS with billing takes more review time than a single-tenant MVP.
- Fix rate
- If you want fix PRs instead of notes, that adds hours - reflected in tier choice.
- Tools
- Lovable, Cursor, Bolt, Replit - we review all of them. No stack upcharge.
First week free. If it's not useful, walk away.
FAQ
Vibe Coding With Guardrails FAQ
Do you work with our AI coding tool, or do we have to switch?
Whatever you're using - Lovable, Cursor, Bolt, Replit, Windsurf, Copilot. We review the output, not the tool. Keep what works for you.
Is this code review or code pairing?
Both, depending on tier. Small team gets review + fix PRs. Embedded senior includes daily async pairing and custom patterns work.
What if the AI is generating hundreds of lines a day?
That's the point. A senior engineer reading every merge against a real checklist is the only scalable way to keep vibe coding safe. We'd rather review 30 PRs a week than debug one production fire.
Can you fix the issues yourselves?
Yes - on Small team and above, we'll open fix PRs when shipping the fix is faster than writing a note explaining it. You still approve every merge.
What happens after 30 days if it's not working?
You cancel. No exit fee, no 90-day notice, no theatrics. First week is free anyway. We earn the next month every month.
How do we start?
Give us repo access and we'll review the first 3 PRs free this week. That's the sell.
