Implement a complete double-entry accounting system inside any SaaS app. Users enter transactions naturally (sales, expenses, inventory) while the system auto-posts journal entries under the hood. Produces both user-friendly reports and technical financial statements (Trial Balance, Balance Sheet, Income Statement, Cash Flow). Enforces 10000% accuracy with balanced entries and seamless void/reversal mechanics. Use when building any financial, ERP, POS, or inventory system that needs proper accounting.
Use when building or reviewing core Quarkus applications with CDI beans and scopes, SmallRye Config and profiles, lifecycle, interceptors and events, health probes, virtual threads, and test-friendly design. Part of the skills-for-java project
Use when you need to write fast unit tests for Quarkus applications — including pure tests with @ExtendWith(MockitoExtension.class), @QuarkusTest with @InjectMock for full CDI mock replacement, @InjectSpy for partial CDI bean mocking, REST Assured for resource-focused tests, @ParameterizedTest with @CsvSource / @MethodSource, QuarkusTestProfile for test-specific configuration overrides, and naming conventions (*Test → Surefire, *IT → Failsafe). For framework-agnostic Java use @131-java-testing-unit-testing. Part of the skills-for-java project

Runs tilth CLI for structural code navigation — reads files with smart outlining, searches symbols/text/regex, finds files by glob, and maps codebases. Use instead of read/grep/find for all source code exploration.
Verify whether a GitHub issue is fixed in the local codebase. User provides a GitHub issue URL, the skill fetches it, extracts reproduction steps, builds the product from source, runs the reproduction steps, and reports whether the issue still exists or not.
