What problem does it solve? Developers often start coding without reviewing project conventions, leading to inconsistent patterns, missed standards, and rework. This Skill ensures the AI reads the relevant spec indexes, pre-development checklists, and shared guides from the .trellis/spec/ directory before writing any code. ## Core Features & Use Cases - Spec Discovery: Runs get_context.py to enumerate packages and their spec layers, then reads the relevant index.md files for the target package. - Pre-Development Checklists: Follows checklist sections in spec indexes to load concrete guideline files like error-handling.md, conventions.md, and mock-strategies.md. - Change Boundary Declaration: For non-trivial tasks, requires stating the behavior gap, affected files, and explicit scope exclusions before coding. - Use Case: Before modifying the cli/ package, the Skill reads the package's spec index, loads the listed guideline files, and confirms conventions so the implementation matches project standards. ## Quick Start Before writing any code for this task, load the relevant Trellis specs and pre-development checklists for the package I am about to modify.
