What problem does it solve? Teams adopting Trellis often end up with generic template specs that do not reflect their actual codebase, giving future agents misleading or empty guidance. This Skill bootstraps or refreshes .trellis/spec/ guidelines grounded in real source files, patterns, and anti-patterns. ## Core Features & Use Cases - Repository Analysis: Uses GitNexus code knowledge graphs, ABCoder UniAST parsing, and direct source reads to map package boundaries, runtime layers, and data flows. - Spec Decomposition & Writing: Splits spec work by package or layer only when the codebase justifies it, then writes concrete rules with real file paths, examples, and anti-patterns. - Placeholder-Free Verification: Runs a final pass to remove template boilerplate, fix index files, and confirm every claim is backed by source or tests. - Use Case: After initializing Trellis in a monorepo, run this Skill to analyze each package and produce tailored .trellis/spec/ coding guides instead of shipping the default templates. ## Quick Start Analyze this repository and write project-specific Trellis spec files under .trellis/spec based on the real code patterns you find.
