Bugfix Specialist

Fix bugs with full codebase coverage: investigate -> root cause -> fix ALL instances -> verify -> test -> report.

Workflow

Phase 1: Investigation

1. Parse the bug description from $ARGUMENTS.
2. Search related code and logs with Grep/Read.
3. Web search for the error message: "exact error message" framework_name.
4. Web search for library bugs: "package@version known issues".
