solid-swift SKILL.md skillA
solid-swift from fusengine/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add fusengine/agents/solid-swift@git:20261012.0cd6b32Pins git:20261012.0cd6b32 in mdr.lock. Pin the fingerprint instead.

Use when applying SOLID principles to Swift 6/SwiftUI code — file-size limits, protocol separation, @Observable, actors, feature-modular architecture.
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
<objective> Enforces SOLID and DRY principles for Swift 6 and SwiftUI (iOS 27+) projects: a mandatory Features/[Feature]/ modular directory structure (never a flat Sources/ layout), one responsibility per file with the hook's ceiling (`FUSE_SOLID_MAX_LINES`) as the only line limit, protocols separated into their own Protocols/ directories, @Observable + @MainActor for ViewModels, Sendable structs for models, and mandatory #Preview on every View. Covers all five SOLID principles with dedicated references (SRP, OCP, LSP, ISP, DIP), concurrency patterns (actors, @MainActor, Sendable), an anti-pattern catalog, and code templates for views, view models, services, protocols, and models. Requires grepping the codebase for reusable protocols/services before writing new code, and checking shared locations (Core/Extensions/, Core/Utilities/, Core/Protocols/) before duplicating logic used by 2+ features. </objective> # SOLID Swift - Apple Best Practices 2026 ## Agent Workflow (MANDATORY) Before ANY implementation, spawn 3 agents in parallel, one `Agent` call each with a `name`: 1. **fuse-ai-pilot:explore-codebase** - Analyze existing architecture …

How to install
mdr add fusengine/agents/solid-swift@sha256:41a06abe5dca908bThe line at the top of this page pins the label git:20261012.0cd6b32, 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.
