Example: Reproduce pricing total mismatch
User task: "I see order totals are incorrect after discount applied. Create a failing spec that reproduces the bug and produce a minimal fix plan."
Expected triage output (JSON):
{ "title": "Order total wrong with discount", "reproduction_steps": [ "Create cart with item price 100, quantity 1", "Apply 10% discount code 'TEN'", "Call Pricing::Calculator.total on line_items" ], "failing_command": "bundle exec rspec spec/services/pricing/reproduction_spec.rb", "failing_tests": ["Pricing::Calculator reproduces incorrect total when discount applied"], "minimal_fix_plan": [ "Investigate discount application order in Pricing::Calculator", "Add nil-safe guard and correct discount rounding in total method", "Add unit test and run full spec suite" ] }
Use the spec skeleton in assets/spec-skeletons/reproduction_spec.rb as the starting point for the failing test.
