"Vibe coding" without the mess: 7 guardrails that avoid rework

"Vibe coding" popularized the idea of programming by describing what you want and letting the AI do it. The risk: unbounded speed becomes invisible tech debt — and you only find out when it breaks in production.

The real risk of vibe

Building fast without criteria produces code that "works" until someone changes one detail. Maintenance cost explodes and confidence in using AI drops.

7 golden rules

1. Definition of Done: tests + lint + build required before merge.
2. Critical paths: don't accept code without tests for auth, payments or sensitive data.
3. Risks and assumptions: ask the AI (and the author) to list risks and assumptions before the patch.
4. Locked standards: eslint, prettier and commit hooks in CI.
5. Small PRs: limit files per PR (e.g. up to 15) to force incremental delivery.
6. Edge list: nulls, timezones, permissions — document and test.
7. Recorded decisions: short ADR or DECISIONS.md for architecture changes.

When NOT to delegate

Don't delegate without deep review: authentication, payments, permissions and crypto. If you use AI aggressively, use aggressive rules too.

Common mistakes

Accepting "it works" without running the test suite. Letting the AI change dependencies without review. Ignoring lint or type-check warnings.

Step by step

1. Set up the 7 guardrails in your repo (CI + docs).
2. On every PR with AI-generated code, require tests and human review on critical paths.
3. Once per sprint, review whether the limits (PR size, coverage) still make sense.

Key takeaways

Vibe coding can speed things up, but without guardrails it becomes rework. The 7 items above are a minimum viable set. Don't delegate auth, payments or crypto without review.

FAQ

Do I need all 7? Start with DoD, tests on critical paths and small PRs. Add the rest as pain appears.

What if the team is small? Guardrails help more in small teams: they stop one person from accumulating AI debt.

How to convince the team? Show a PR that "broke in prod" for lack of tests or review and propose a simple rule (e.g. every PR with more than X files needs two approvers).
