mac-app-send

Drive a native macOS app with the computer-use MCP to send a formatted message and attach files — the method skill, a preflight doctor that resolves the bundle id and grant state in one shot, a deterministic file manifest for verifying a send against disk, and a PreToolUse guard that blocks the three known-wrong moves before they cost a turn: an osascript workaround at the Open/Save panel, a multi-line app_type without element_index, and request_access on the panel service that can never be granted.

Drive a native macOS app with the computer-use MCP to send a formatted message and/or file attachments — WhatsApp Desktop is the worked example, but the Open/Save panel technique applies to ANY Mac app that attaches, imports, exports or saves a file. Use when the user asks to "send X on WhatsApp", "message them this PDF", "attach the file in <Mac app>", "text them the document", or whenever an `app_*` tool refuses a file chooser. NOT for web apps (use the browser MCP) and NOT for services that have a dedicated MCP — Gmail, Slack, Calendar, Linear — reach for those first; they are API-backed and verifiable.
