architecture-builder skillA
architecture-builder is agent-read markdown (skill) from vmobifystudio/app-dev-team: Use to produce the technical architecture doc and engineering principles for a mobile app. Used primarily by the CTO agent. Triggers on "design the architecture", "pick the stack", or as part of /app-plan..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Architecture builder
Produce `docs/20-architecture.md` and `docs/21-engineering-principles.md` from `docs/00-vision.md` + `docs/10-prd.md`.
## docs/20-architecture.md sections
1. **Platform decision** — iOS / Android / both, with order if sequential.
2. **iOS stack** —
- Swift version (latest stable)
- Minimum iOS target — resolve `knowledge/stack-defaults.md`'s relative rule (flagship =
latest major minus one) to a **concrete number** here, and record how you resolved it
- UI: SwiftUI by default; UIKit only if PRD demands something SwiftUI struggles with
- State: `@Observable` + `@MainActor` on ViewModels only (Combine / `@Published` /
`ObservableObject` are forbidden — `knowledge/ios-conventions.md`)
- Networking: URLSession + async/await, or a named lib
- Persistence: SwiftData (content apps) or GRDB+SQLite/FTS5 (camera/media) — pick by PRD complexity
- DI: lightweight — protocol + initializer injection
- Testing: **Swift Testing** (`@Test`/`@Suite`) for unit and domain tests, not XCTest. **UI
automation stays XCUITest** — it is XCTest-based, has no Swift Testing equivalent, and

How to install
mdr add vmobifystudio/app-dev-team/architecture-builder@git:20260729.6f1f11emdr add vmobifystudio/app-dev-team/architecture-builder@sha256:70994a3939a6065fPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
