Cursor & Claude Code Cleanup

Refactoring AI pair-programming output that nobody can maintain anymore

You spent weeks in Cursor, Claude Code, or Windsurf, and now you have 1,000-line files, hallucinated imports, zero tests, and TypeScript that's basically in "any" mode? We clean it up into something maintainable and production-grade, without breaking what already works.

Cursor and Claude Code can write code in an hour that would take a human a week. They also write 1,500-line React components with hallucinated imports, zero tests, and TypeScript errors nobody understands. Refactoring that kind of code is what we do every day.

We start with a code audit in 3-5 days that identifies the biggest debt: 1,000+ line files, hallucinated API calls, "any" types, dead code, duplicated logic, and exposed security issues. The cleanup plan is prioritized by business impact, we refactor the parts that block further work or pose risk first. We work in small feature branches with proper PR review, no big-bang rewrites. Before refactoring each module we add tests so we know nothing breaks. We decompose giant files by responsibility, enable strict TypeScript incrementally, fix hallucinated imports, and unify the inconsistent interfaces left behind by different AI generations. We finish by setting up a CI/CD pipeline with lint, typecheck, and test gates, no further AI-generated PR ships to production without passing them. We hand back updated .cursorrules and .clauderules that generate higher-quality code going forward.

  • Decomposition of giant AI-generated files into maintainable modules with explicit interfaces
  • Incremental strict TypeScript rollout fixing every "any" left behind by AI generations
  • Automated test suite for critical business logic, target 60-80% coverage
  • CI/CD pipeline with lint, typecheck, and test gates, no untested code ships to production

What's included

What You Get

Decomposing massive files

We split 1,000-3,000 line files by responsibility, create clean modules with explicit interfaces, and remove circular dependencies.

Strict TypeScript pass

We enable strict mode, fix every "any" type, add missing type guards, and unify the inconsistent interface definitions left behind by multiple AI generations.

Hallucination removal

We find and fix calls to non-existent APIs, broken imports, broken regexes, and logic that came from an AI mistake and was never actually tested.

Automated test suite

Unit tests for critical business logic, integration tests for API endpoints, smoke tests for the main flows. Goal: no more regressions on the next AI refactor.

Dependency cleanup

Remove unused packages, unify versions, patch known security vulnerabilities (npm audit), and reduce bundle size.

CI/CD and code quality gates

GitHub Actions / Cloudflare pipelines with lint, typecheck, and test gates. AI never ships untested code to production again.

Perfect for

Perfect for

  • Teams that leaned hard on Cursor and now can't maintain the output
  • Solo founders with a Claude Code MVP they want to hand off to other devs
  • Projects where Windsurf generated the code but nobody understands its structure anymore
  • Apps where every new feature breaks an old one because nothing is tested

Our Process

How We Work

1

Code audit

We walk through structure, dependencies, types, tests. We identify the worst debt and exposed security issues. 3-5 days.

2

Cleanup plan

We prioritize the refactor by impact, what to break now so it stays easy to fix later vs. what can wait.

3

Incremental refactor

We work component-by-component with feature branches. Tests come before refactoring. No big-bang rewrites.

4

Code quality gates

CI/CD with lint, typecheck, and coverage gates. No PR ships without them.

FAQ

Frequently Asked Questions

Yes. We work on feature branches and submit PRs. Your team keeps shipping on main, we merge cleanup work incrementally. Conflicts are resolved through clear comms.

We document them and update them so they generate maintainable code. After the cleanup we hand back updated .cursorrules and .clauderules files.

Yes, same approach. Windsurf produces similar patterns, huge files, hallucinated imports, no tests. The process is identical.

That's very common. We start with smoke tests for the most important flows, then add unit tests during the refactor. Goal is 60-80% on critical modules.

Yes. We deliver a .cursorrules / .clauderules template with lint rules, code style, architectural constraints, and test requirements. Battle-tested across dozens of projects.
