Summary

This pulls real-world problems and edge cases before you write tests, so you're not just checking acceptance criteria in a vacuum. It searches for common gotchas with the tech stack, how competitors handle the same feature, and what users actually complain about on Stack Overflow and Reddit. Then it drops a structured comment on your story with sourced findings and suggested test cases. Good for anything non-trivial like API integrations or file format handling. Skip it for simple CRUD where the AC tells you everything. The research comment feeds into both manual and automated test planning steps downstream, which is the real point of gathering this stuff upfront.
