What problem does it solve? Bug reports often arrive vague, unverified, or mixed with unrelated environment issues, forcing maintainers to guess whether a failure is real. This Skill turns a reported bug into a minimal, independently rerunnable reproduction with documented evidence. ## Core Features & Use Cases - Minimal Reproduction: Reduces the failing case to the smallest input that still shows the same observable failure, without modifying production code. - Evidence Recording: Captures runtime version, working directory, command arguments, exit status, and output, while separating environment setup failures from application failures. - Clear Verdicts: Returns one of three outcomes: reproduced, not reproduced on this version, or blocked by a named environmental or input problem. - Use Case: A maintainer receives an issue claiming a CLI crashes on a specific input. The Skill inspects the entrypoint, runs the command in a disposable workspace, shrinks the failing input, and reports exact rerun steps for another maintainer. ## Quick Start Ask the agent to verify this bug report by building a minimal reproduction and reporting the exact command, environment, and observed failure.
