What problem does it solve? New Trellis projects ship with generic spec templates full of placeholder text that give agents no real guidance. This Skill analyzes the actual repository and rewrites .trellis/spec/ into concrete, source-backed coding guidelines. ## Core Features & Use Cases - Repository Analysis: Uses GitNexus code graphs, ABCoder AST parsing, and direct source reads to map package boundaries, runtime layers, and core abstractions. - Spec Decomposition & Writing: Splits spec work by package or layer only when the codebase justifies it, then writes rules backed by real file paths, examples, and anti-patterns. - Placeholder Verification: Runs a final pass to remove template boilerplate, fix index files, and confirm every claim traces to source or tests. - Use Case: After running trellis init on a monorepo, invoke this Skill to replace the default spec templates with package-specific guidance derived from the actual TypeScript sources and tests. ## Quick Start Analyze this repository and rewrite the .trellis/spec directory with concrete, source-backed coding guidelines for each package.
