Paste the error. Get the root cause, the fix, and the regression test.
Takes error messages, stack traces, bug reports, or vague "it's just slow" complaints and works backwards to the root cause through systematic stack trace analysis and execution path tracing. Reads the relevant source files, reproduces the issue โ generating a minimal reproduction case when the bug cannot be immediately triggered โ and identifies the root cause, not just the symptom: race conditions, null references, off-by-one errors, type coercions, memory leaks. Writes a regression test that fails on the current code, applies the minimal fix targeting only the root cause, verifies the test passes, and runs the full suite to detect regressions introduced by the change. Explains the root cause in plain language with fix suggestions so the bug pattern does not repeat across the codebase. Integrates with CI pipelines for automated regression detection on every push.
