Implementation Reference
- Handler function that validates input args using type guard and delegates to LinearService.convertIssueToSubtask to perform the conversion.
export function handleConvertIssueToSubtask(linearService: LinearService) { return async (args: unknown) => { try { if (!isConvertIssueToSubtaskArgs(args)) { throw new Error('Invalid arguments for convertIssueToSubtask'); } return await linearService.convertIssueToSubtask(args.issueId, args.parentIssueId); } catch (error) { logError('Error converting issue to subtask', error); throw error; } }; } - Tool schema definition including input/output schemas for linear_convertIssueToSubtask.
