Multi-client outbound for lead gen agencies — infrastructure architecture, client isolation, domain strategy, warmup at scale, white-labeling, unified reporting, client onboarding playbooks, and cross-client operations. Use when setting up agency outbound infrastructure, onboarding new clients, isolating sending domains per client, managing warmup across 20+ mailboxes, building repeatable client onboarding processes, or designing agency-wide reporting. Do NOT use for Smartlead-specific platform config (use /sales-smartlead), single-domain deliverability (use /sales-deliverability), or individual campaign strategy (use /sales-cadence).
Spring Boot best practices and patterns. Use when creating controllers, services, repositories, or when user asks about Spring Boot architecture, REST APIs, exception handling, or JPA patterns.
Executes full-project QA like a real user by discovering the repository verification and E2E contracts, running build, lint, test, and startup commands, exercising core workflows end-to-end through CLI, HTTP, and browser interfaces, requiring automated regression coverage for supported critical flows, fixing root-cause regressions, and rerunning the full gate. Uses the agent-browser companion skill for Web UI validation when a web surface exists. Use when validating a branch, release candidate, migration, refactor, or risky commit. Do not use for static code review only, one-off unit test edits, planning test cases, or architecture brainstorming without execution — use qa-report for planning and documentation.
Use when user requests diagrams, flowcharts, architecture charts, or visualizations. Also use proactively when explaining systems with 3+ components, complex data flows, or relationships that benefit from visual representation. Generates .drawio XML files and exports to PNG/SVG/PDF locally using the native draw.io desktop CLI.
Expert guidance on Swift Concurrency best practices, patterns, and implementation. Use when developers mention: (1) Swift Concurrency, async/await, actors, or tasks, (2) "use Swift Concurrency" or "modern concurrency patterns", (3) migrating to Swift 6, (4) data races or thread safety issues, (5) refactoring closures to async/await, (6) @MainActor, Sendable, or actor isolation, (7) concurrent code architecture or performance optimization, (8) concurrency-related linter warnings (SwiftLint or similar; e.g. async_without_await, Sendable/actor isolation/MainActor lint).
Use when designing REST or GraphQL APIs, creating OpenAPI specifications, or planning API architecture. Invoke for resource modeling, versioning strategies, pagination patterns, error handling standards.
