Use when writing or editing code inside the Schematika repo (src/schematika/**), especially the new schematika.pcb module that bridges SKiDL to Schematika, or adding symbol factories under electrical/symbols/. Covers repo layout, the data-returning module convention, Project integration, frozen-dataclass style, and pre-commit/ty/pytest tooling.

Use when the user asks to check library quality, run a health check, audit the codebase, or detect regressions - runs metrics, structural audits, rendering validation, and auto-fixes simple issues
