name: architecture-guard description: Enforce Swift layering and boundary safety rules for this repository. Use when source/test files change, before commit, during architecture reviews, or when checking whether a refactor introduced dependency-direction violations or direct external entropy/time/I/O usage in engine-domain code.

Run repository-level architecture checks with deterministic output.

Workflow

•
Run staged checks before commit:
- •bash .codex/skills/architecture-guard/scripts/check_layering.sh --staged
•Fix all blockers ([ERROR]) first.
•Review warnings ([WARN]) and either fix or explain in PR notes.
•
Optionally run a full scan when planning larger refactors:
- •bash .codex/skills/architecture-guard/scripts/check_layering.sh --all

What This Skill Checks

•SwiftUI import leakage outside the presentation allowlist.
•
Direct entropy/time/I/O API usage in engine-domain candidate files:
- •Int.random, Bool.random, Date(), Date.now, UUID(), FileManager.default, URLSession, UserDefaults.standard.
•
Boundary-risk warnings:
- •Source changes without test changes in staged mode.
- •New public declarations in source files.

Scope Notes

•--staged is the default mode and is intended for day-to-day commits.
•--all is intentionally strict and may surface existing legacy debt.
•Treat this skill as the enforcement tool for the architecture section in AGENTS.md.
