Each agent invokes skills dynamically based on the task rather than embedding all knowledge in the prompt. - arc-swift-tdd (sonnet): TDD implementation, writes tests before code - arc-swift-reviewer (sonnet): delegated code review, structured report - arc-swift-debugger (sonnet): build/test failure diagnosis, env-first - arc-spm-manager (haiku): Package.swift management and verification - arc-xcode-explorer (haiku): read-only codebase navigation and mapping - arc-linear-bridge (haiku): Linear ticket to Swift test scaffolding * docs(agents): add AGENTS.md index with trigger phrases and design principles * docs(skills): add Agents section to skills-index with routing table * docs(arc-final-review): clarify guided vs delegated review distinction * feat(arc-linear-bridge): create branch automatically after scaffolding Add mcp__ARC_Linear_GitHub__github_create_branch to tools.

Add ARCPurchasing (RevenueCat IAP) and ARCAuthentication (SIWA + Vapor) to the known packages table with product names and domains. * feat(agents): add arc-pr-publisher and arc-release-orchestrator arc-pr-publisher: validates pre-PR checklist, creates GitHub PR, links Linear ticket, updates issue to "In Review". Closes the workflow gap between code review and merge. arc-release-orchestrator: bumps version, updates CHANGELOG, creates release branch and PR. Confirms version with user before edits. Reports manual steps (tag + App Store) after PR merge. * docs(agents): update index for 8-agent system and package table * feat(agents): add arc-testflight distribution agent Orchestrates archive → upload → TestFlight configuration. Distinct from arc-release-orchestrator (code/PR) — handles beta distribution only: tester groups, release notes, ExportOptions. * feat(agents): add arc-aso App Store Optimization agent Orchestrates 8 ASO skills (app-marketing-context, aso-audit, keyword-research, metadata-optimization, screenshot-optimization, app-store-featured, ab-test-store-listing, app-launch). Produces ready-to-upload metadata files in aso/[bundle-id]/. * feat(agents): add arc-swiftdata-migration high-risk schema agent Most conservative agent in the system. Classifies changes as lightweight vs custom, confirms before any breaking change, and enforces test-before-code for all migration plans. Invokes swiftdata-pro, axiom migration skills, arc-data-layer, arc-tdd-patterns. * feat(agents): add arc-dependency-auditor read-only audit agent Audits SPM dependencies across the project ecosystem. Detects outdated packages, version inconsistencies, and branch/revision pins. Produces a prioritized report; delegates updates to arc-spm-manager. * docs(agents): update AGENTS.md from 8 to 12 agents Add entries for arc-testflight, arc-aso, arc-swiftdata-migration, arc-dependency-auditor. Update master skills/MCPs table with all 4 new agents and their skill/MCP dependencies. * docs(skills): add 4 new agents to skills-index agents section Add arc-testflight, arc-aso, arc-swiftdata-migration, arc-dependency-auditor to the ARC Labs Agents table with model selection and trigger phrases. * Feature/swift solid pattern (#65) * docs(architecture): add swift-design-principles foundational document Six Swift-native design principles for ARC Labs Studio: Value Semantics by Default, Protocol-Driven Abstraction, Composition Over Inheritance, Well-Defined Ownership, Structured Concurrency, and Compile-Time Correctness. Includes SOLID mapping table, anti-patterns section, and full references (WWDC, Swift Evolution, Apple docs). Motivated by Fernández Muñoz's critique of SOLID in Swift and two prior sessions that refined the position: SOLID is not dead but its intent is expressed through Swift-native vocabulary and mechanisms. Co-located reference copy added to arc-swift-architecture skill references. * docs(architecture): add cross-references to swift-design-principles - solid-principles.md: add ARC Labs context note positioning SOLID as a reference framework interpreted through the Swift design principles lens - protocol-oriented.md: add cross-reference to swift-design-principles as the broader philosophical framework * docs(skills): update arc-swift-architecture with swift design principles Replace the SOLID Quick Guide section with the six Swift design principles summary. Add swift-design-principles.md as the primary architecture reference, positioned before clean-architecture.md. * docs(claude): surface swift design principles in agent guide and index - CLAUDE.md: replace bare "SOLID Principles" technical principle with the six Swift design principles and a link to swift-design-principles.md; SOLID remains referenced as a useful historical framework - Skills/skills-index.md: update arc-swift-architecture entry to mention Swift design principles alongside MVVM+C * chore(release): prepare v2.10.0 - README.md: add swift-design-principles.md to Architecture directory listing and arc-swift-architecture skill files table - CHANGELOG.md: document v2.10.0 with all added and changed files * docs(standards): add @Environment DI guidance and fix @mainactor patterns - Add Dependency Injection Strategy section to presentation.md with a decision matrix (init injection vs @Environment), @entry macro (iOS 18+), type-based @Environment for @observable (iOS 17+), anti-patterns, and @EnvironmentObject deprecation note - Fix @mainactor inconsistency: remove blanket annotation from ViewModel class declarations; add it only to methods that await nonisolated code and write to @observable state (matches CLAUDE.md rule #14) - Add @mainactor Placement explanation section backed by SE-0316 and SE-0466 (Swift 6.2 DefaultIsolation), clarifying why class-level is wrong for packages and when method-level annotation is required - Remove redundant @mainactor from pure-delegation methods (onAppear, onTappedRetry) — the main-actor hop happens inside the callee - Restore private modifier on loadRestaurants example - Add Router @Environment rationale callout to mvvm-c.md - Add cross-reference and DIP row clarification to swift-design-principles.md - Sync all changes to skill reference copies

Motivated by Fernández Muñoz's critique of SOLID in Swift and two prior sessions that refined the position: SOLID is not dead but its intent is expressed through Swift-native vocabulary and mechanisms. Co-located reference copy added to arc-swift-architecture skill references. * docs(architecture): add cross-references to swift-design-principles - solid-principles.md: add ARC Labs context note positioning SOLID as a reference framework interpreted through the Swift design principles lens - protocol-oriented.md: add cross-reference to swift-design-principles as the broader philosophical framework * docs(skills): update arc-swift-architecture with swift design principles Replace the SOLID Quick Guide section with the six Swift design principles summary.

PR #67 was accidentally merged directly to
main. PR #68 (develop→main) followed. Since force-push tomainis not possible, this PR brings the feature through the correctfeature → developflow. The next develop→main merge will reconcile cleanly.
