The autonomous developer copilot that catches failing tests, synthesizes isolated reproduction proofs, applies surgical AST patches, and ships a verified green PR before your team even opens Slack.
Four deterministic steps replace LLM hallucination with guaranteed correctness.
The moment your GitHub Actions or GitLab CI workflow fails, Bartholomew ingests the webhook and spins up an isolated sandbox. It executes a standalone reproduction proof that confirms the defect is real and reproducible with zero false positives.
Instead of blindly rewriting files, Bartholomew uses compiler-level AST analysis to compute the exact minimal AST mutation required to solve the root defect without collateral changes.
Every test in your test suite executes against the synthesized patch. Only when all tests pass with zero regressions does Bartholomew approve the change.
A clean, documented, mergeable Pull Request appears with full reproduction proof logs attached. Your team merges with absolute confidence.
