Debugging AI-Generated Code

45% of developers report debugging AI-generated code is more time-consuming than debugging their own; 66% cite 'AI solutions that are almost right, but not quite' as their single biggest frustration (2025 SO Developer Survey).

AI-generated code often looks plausible at first glance but harbors subtle flaws — hallucinated methods, missing edge cases, and unchecked error paths — that turn debugging into a time sink. This tool surfaces those "almost right" problems before they reach production by statically scanning source code for the specific anti-patterns that AI assistants frequently introduce.

Use Cases

• Pre-review lint pass for AI-assisted commits: Run the validator on a diff before opening a pull request to catch missing try/except blocks and absent None checks that generative models tend to omit.
• Auditing LLM tutoring sessions: When learners submit code copied from an AI tutor, instructors can identify whether the snippet includes hallucinated method calls (e.g., methods matching patterns like .get_data_from_source() or .process_input_stream()) that would never resolve against a real library.
• Flagging fragile refactors: Spot code sections lacking defensive programming so reviewers know which blocks to harden before merging into a shared codebase.
• Complexity triage on auto-generated snippets: Use the heuristic nesting- and density-based complexity score to decide whether a generated function is simple enough to trust at a glance or warrants deeper manual review.
• Curriculum and training data QA: Filter a dataset of model outputs to retain only snippets that pass baseline edge-case and error-handling checks, improving the quality of fine-tuning corpora.

How It Works

The CodeValidator class splits the input source into individual lines and runs three independent heuristic checks. _check_hallucinated_methods applies a curated set of regular expressions to flag method invocations that match suspiciously generic, AI-typical naming patterns rather than real library APIs. _check_missing_edge_cases performs a textual scan to verify that the code contains try/except constructs and explicit is None guards, returning suggestions when neither is present. Finally, _check_complexity aggregates an indentation- and density-based score so callers can gauge how much cognitive overhead the snippet carries. Results from all checks are bundled into a DiagnosticResult dataclass that reports validity, the offending error category, a list of actionable suggestions, and the complexity score.
