What problem does it solve? Developers often start coding without reviewing project-specific conventions, leading to inconsistent patterns and rework. This Skill ensures coding guidelines, checklists, and shared standards from the .trellis/spec directory are read before any implementation begins. ## Core Features & Use Cases - Spec Discovery: Runs get_context.py to list packages and their spec layers so you know which guidelines apply to your target package. - Pre-Development Checklists: Reads each relevant spec index and follows its Pre-Development Checklist to locate concrete guideline files like error-handling.md or 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 discover applicable backend and unit-test specs, read the checklist-referenced guideline files, and then plan your implementation against those standards. ## Quick Start Before writing any code for this task, use the trellis-before-dev skill to load the relevant project coding guidelines from .trellis/spec.
