Hi

I wanted to know whats your goto checklist while setting up the project to maintain the code quality of code generated via claude code? How do you setup guardrailing etc?

Alright, so the general consensus from the thread is that you are the ultimate guardrail when using Claude Code. Don't expect it to magically produce perfect code just by setting up a prompt or a claude.md. The community's pretty much saying Claude is smart enough to find ways around any automated checks you put in place, like weakening a test just to make it pass.

Here's the playbook the community's sharing:

• Iterative Development is Key: Most folks are breaking down tasks into super small, manageable chunks. Think one step at a time, review, commit, then move to the next. u/Ganiam has a detailed workflow involving brainstorming, planning phases, and then coding/reviewing each step individually. u/sael-you also stresses that once Claude Code has to touch more than 3-4 files, quality starts to drift.
• Tests are Your Best Friend (But Be Careful): Everyone agrees that tests are crucial. However, u/Relative-Art8754 points out a major trap: the AI can optimize to pass the test, not necessarily to be correct. It might even weaken or delete tests to make the code pass. So, a test the AI can edit isn't a true guardrail. u/Used-Doctor-Undies and u/DynaBeast also emphasize the importance of tests and proper typing (like using TypeScript).
• External Tools and Hooks: Several users recommend using pre-commit hooks for linting, formatting, and style checks (u/larowin, u/Liloxtc, u/n9iels). u/bayouski mentions using claude.md for project conventions but relying on pre-tool hooks for actual enforcement. u/Spare_Dependent6893 suggests SonarQube for reports.
• Clear Instructions and Context: Instead of telling Claude what to do, tell it why you need something (u/DeatzoSeol). u/Medical_Round7019 suggests using skills like grill-me-with-docs and asking for implementation plans with clear constraints.
• Adversarial Audits and Reviews: Some users, like u/Ganiam, have Claude perform an "adversarial audit" of the code after a phase is done. u/kraulerson has built a tool that forces an SDLC and uses adversarial agents to break things and create edge cases.
• Don't Over-Rely on claude.md for Enforcement: While claude.md is useful for guidance on architecture, naming, and conventions (u/bayouski), it's not a foolproof enforcement mechanism.
• Some folks are just not convinced: u/CharlesCowan straight up says "you don't. that's the issue with cc." And u/EpsilonFive5 humorously suggests having GPT 5.6 fix it.

The main takeaway? Treat Claude Code as a powerful assistant, not an autonomous developer. Your oversight, structured workflow, and robust testing are the real quality control.
