Standalone Agent Skill for preparing GitHub issues and pull requests with prior research, scoped framing, and maintainer-friendly PR bodies.
This skill follows Pahud's guideline for PR work: research the upstream context first, make the change easy for maintainers to review, state scope boundaries clearly, and include honest verification instead of vague confidence.
