Use for any question about The Composable Architecture (TCA) — defining reducers, managing state, handling navigation, writing tests, or working with dependencies. Essential when encountering TCA-specific types like @Reducer, @ObservableState, StackState, StackAction, @Presents, TestStore, @DependencyClient, Scope, or delegate actions. Also use when debugging TCA compiler errors, decomposing large reducers into child features, migrating from old TCA patterns…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> **Approach: Production-First Iterative Refactoring** — This skill is built for production enterprise codebases using The Composable Architecture. Architecture changes are delivered through iterative refactoring — small, focused PRs tracked in a `refactoring/` directory. AI tools consistently generate outdated TCA code (pre-1.4 patterns, WithViewStore, Environment, Combine Effects). Every rule here exists to prevent those mistakes. # TCA SwiftUI Architecture (iOS 16+, TCA 1.7+) Enterprise-grade skill for The Composable Architecture (point-free/swift-composable-architecture). Opinionated: prescribes `@Reducer` macro, `@ObservableState`, struct-of-closures dependencies, delegate actions for child-parent communication, and modern navigation via `@Presents`/`StackState`. TCA's API changed substantially across versions — AI tools trained on pre-1.7 code consistently generate `WithViewStore`, `IfLetStore`, `Environment`, and other removed patterns. This skill encodes the modern (1.7+) patterns validated against real enterprise codebases. > **If the project uses TCA <1.7**, consult `references/migration.md` for pre-macro patterns and incremental upgrade path. ## Architecture Layers …

How to install
mdr add rusel95/ios-agent-skills/tca-swiftui@sha256:42e921fa414f43a6The line at the top of this page pins the label v1.0.3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
