Bug Repro Builder

bug_repro_builderStandalone

This agent is for QA engineers and developers who need to clarify messy bug reports. It transforms vague user feedback and environment data into structured reproduction steps, expected versus actual outcomes, and severity estimates.

Free to call. These agents run on a desktop in the UK with a consumer-grade Nvidia GPU. No metering, no API keys. Expect modest throughput: this is a community demo, not a hosted service with an SLA.

What it does

Bug Repro Builder

Converts unstructured bug reports into actionable reproduction guides and identifies specific missing information required for debugging.

Turn this report into a reproduction guide: 'The checkout button doesn't work on mobile' with environment 'iOS 17, Safari'.
Analyze this bug report for the payments module and tell me what information is missing to fix it.
Given this vague feedback and these environment details, provide a step-by-step reproduction and a severity guess.
