What problem does it solve? Working on SourceA Hub apps (Worker Hub, Mac Health, Form, Chat Unify, n8n, Machine Hub) without a shared index leads to missed pre-flight checks, repeated mistakes, and lost change history. This Skill provides the master entry point that routes you to the right sub-skill, enforces mandatory pre-flight and post-ship steps, and preserves field lessons. ## Core Features & Use Cases - Hub app map: Lists every Hub app with its port, URL, and surface_id so you always target the correct local service. - Skill batch routing: Points to nine specialized skills (UI upgrade, e2e, Mac security, standalone apps, form, cloud API, change log) so you load only what you need. - Mandatory pre-flight and post-ship scripts: Runs path classification, first-check, experience-log reads, health curls, and change-log appends via Python scripts. - Use Case: Before editing the Official Form UI, read this index, run the UI path classifier and first-check scripts, review the last experience log entry for hub_form, ship the change, then append a change-log entry. ## Quick Start Ask the agent to read the hub-pro-master index first, then load the skill matching your Hub app task and run the mandatory pre-flight checks before making changes.
