What problem does it solve? New team members joining a project that uses the Trellis AI-assisted workflow need to understand why the workflow exists, how each skill works, and whether the project's development guidelines are properly configured. This Skill provides a structured, mentor-style onboarding that explains the system end to end. ## Core Features & Use Cases - Concept Teaching: Explains the three core challenges of AI-assisted development (no memory, generic knowledge, limited context) and how the Trellis workflow addresses each one. - Real-World Workflow Walkthroughs: Walks through five detailed examples covering bug fixes, planning sessions, code review fixes, large refactorings, and debug sessions. - Guideline Customization: Checks whether .trellis/spec/ guidelines are still empty templates and helps the developer fill them with project-specific conventions. - Use Case: A developer clones a repository using Trellis for the first time and runs the onboard skill to learn the workflow, then discovers the backend guidelines are empty templates and gets guided help filling them based on the existing codebase. ## Quick Start Ask the AI to onboard you to this project's Trellis workflow and check whether the development guidelines need to be customized.
