What problem does it solve? Developers often start coding without reviewing project conventions, leading to inconsistent patterns, rejected reviews, and rework. This Skill ensures coding standards, error-handling rules, and testing strategies are loaded into context before any code is written. ## Core Features & Use Cases - Spec Discovery: Runs get_context.py to enumerate packages and their spec layers so you know which guidelines apply to your target package. - Checklist-Driven Reading: Follows the Pre-Development Checklist in each spec index to locate concrete guideline files like error-handling.md and conventions.md. - Shared Guides: Always loads the shared thinking guides under .trellis/spec/guides/ for cross-package standards. - Use Case: Before modifying the cli/ package, run this Skill to read the backend and unit-test spec indexes, then follow the listed guideline files so your implementation matches project conventions from the start. ## Quick Start Before writing any code, load the Trellis development guidelines for the package I am about to modify.
