The request asks for a tool to add items to a project. Vercel's indexed actions include addProjectDomain and updateProject, but none adds items to a project directly; Linear's linear_update_project changes a project's fields, and Stripe's PostInvoicesInvoiceAddLines bulk-adds line items to an invoice. The closest match for adding items to a project is Linear, whose project actions are indexed and which sources show as built for project planning 515. Since the request does not name a platform
A question back: Which platform holds the project, for example Linear, Jira, GitHub Projects or Stripe invoices, so I can name the exact add-item operation?
