Triage and classify new issues for the CSC database repository. Use this skill whenever an issue is opened, assigned to you, or needs classification. Trigger on: new issue triage, "classify this issue", "what type of issue is this", labelling requests, issue assignment, data correction reports, data addition requests, bug reports, feature requests, or any time you need to categorise, label, prioritise, or respond to a GitHub issue. Also use when deciding whether an issue can be auto-fixed or needs human intervention.
