Built with Fine.dev?
Let's make sure it's production-ready.
Fine.dev is an AI developer agent that builds complete features from specifications. It interprets written specs, generates full implementations with tests across your codebase, and creates pull requests for review. We help non-technical founders identify and fix the issues AI tools leave behind.
Common issues we find in Fine.dev code
These are real problems we see in Fine.dev projects during our audits — not hypotheticals.
Spec interpretation may differ significantly from intent
Fine.dev builds exactly what the specification says, not what you meant. Ambiguous specs lead to technically correct implementations that miss the actual product requirement.
Cross-file changes may miss security implications
When Fine.dev generates features spanning multiple files, security-sensitive changes — new endpoints, auth checks, data access patterns — are spread across the PR without a consolidated security review surface.
Generated tests may not cover real-world edge cases
Fine.dev writes tests for the happy path and obvious failure cases from the spec. Edge cases not explicitly mentioned — concurrent requests, null inputs, rate limits — are frequently untested.
Cross-file changes introduce inconsistencies
Large implementations touching many files accumulate subtle inconsistencies — type assumptions that don't hold across modules, different error handling patterns in different files.
Performance not factored into spec-driven implementations
Fine.dev implements features to meet functional specs without considering production query patterns, data volumes, or latency requirements that aren't part of the specification.
No deployment configuration generated for new features
Features that require new environment variables, database migrations, or infrastructure changes don't include the deployment artifacts needed to ship them safely.
Spec-driven code may not follow established project patterns
Fine.dev generates code that meets the spec but may use different architectural patterns, naming conventions, or service abstractions than what your team has established.
Dependency additions not coordinated with existing tech choices
When a spec requires functionality that could be served by an existing library in the project, Fine.dev may add a new dependency rather than reusing what's already there.

Frequently asked questions
How do I write specs that produce good Fine.dev implementations?
Be explicit about edge cases, performance requirements, and error handling expectations. Include examples of the desired behavior. Vague specs produce working-but-wrong implementations. We can help you write effective spec templates.
Can SpringCode review Fine.dev pull requests before merge?
Yes. We review Fine.dev PRs for spec interpretation accuracy, security implications of cross-file changes, edge case coverage in tests, and fit with your project's architectural patterns.
What happens if Fine.dev misinterprets my specification?
You get a PR that passes review but doesn't solve the right problem. Our reviews catch misinterpretations early by verifying the implementation against the original intent, not just the spec text.
Can Fine.dev handle database migrations and deployment changes?
Fine.dev focuses on application code. Database migrations, environment variable documentation, and infrastructure changes need to be created separately. We fill this gap.
Is Fine.dev appropriate for security-sensitive features?
With additional review, yes. Security features need explicit spec coverage of threat models and access control requirements, plus careful human review of the generated auth and data access code before merging.
