/macos-test-diagnoser
Triage failing macOS tests across Xcode and SwiftPM workflows. Use when asked to run macOS tests, narrow failing scopes, explain assertion or crash failures, or separate real test regressions from setup and environment problems.

Other skills on plug-n-skills.
- /architecture-conformance
Use when intended architecture must be compared with implementation: dependency policies, ADRs, ownership rules, drift, erosion, recovered models, and conformance classifications.
Open skill - /architecture-decisions
Use when structural code choices need durable rationale: ADRs, tradeoffs, consequences, reversibility, ownership, review triggers, and validation plans.
Open skill - /architecture-fitness-functions
Use when architecture choices need executable guardrails: dependency rules, cycle checks, boundary tests, ownership review gates, ADR compliance, runtime/resilience checks, and CI fitness functions.
Open skill - /architecture-intelligence
Use whenever code work has structural consequences: project architecture, module boundaries, dependency direction, runtime topology, asynchronous state consistency, ownership, ADRs, fitness functions, or architecture refactoring.
Open skill - /architecture-ownership-topology
Use when architecture crosses ownership or review boundaries: CODEOWNERS/OWNERS, module coverage, cross-owned dependencies, socio-technical coordination, and governance paths.
Open skill - /architecture-refactoring-strategy
Use when code changes need staged structural design: boundary extraction, modularization, dependency inversion, migrations, anti-corruption layers, tests, rollout gates, and rollback.
