What problem does it solve? Handing a user a pasted terminal command or a "just run this" instruction leads to inconsistent execution, lost exec bits, and no clean signal of success or failure. This Skill enforces one sanctioned mechanism: every step the user must run on their own machine becomes a single double-click file (.command on Mac, .bat on PC) delivered with a Show in Folder card. ## Core Features & Use Cases - Deterministic run-file building: Calls a builder script that fills a sanctioned template, names the file, sets the exec bit, and stamps session ownership and tenant-local time. - Turn-one precondition probe: Verifies the run folder can accept an executable file before any work begins, with a fail-loud stop and two named recoveries if it cannot. - Show-in-Folder delivery gate: Sends, binds, re-chmods, and verifies each file so the delivery card defaults to Show in Folder, never a Download-only fallback. - One-step-then-wait loop: Hands one file, stops, waits for the user's screenshot, fixes only the failing step, and never restarts the sequence. - Use Case: During an app deployment, the user must install a CLI tool and set an API key. The Skill builds one .command file per step, delivers each with a Show in Folder card, and waits for a ✅ DONE screenshot before handing the next. ## Quick Start Ask the assistant to give you the install step as a double-click run file you can execute on your machine.
