Prune everything except the bug. BugBonsai turns a failing JavaScript or TypeScript project into a small, shareable reproduction while continuously verifying that the original failure still exists.
Which hunks in your dirty working tree broke the test? Delta debugging below commit granularity.
Replay-verified minimal JSON reproductions and deterministic TypeScript/OpenAPI drift checks. Local-first CLI and MCP server.
A Python library for reducing failing event traces into smaller regression cases, with dependency checks and replay evidence.
Test-guided minimization for Git diffs.
