This skill should be used when the user asks to "implement dependency injection in Python", "use the dependency-injector library", "decouple Python components", "write testable Python services", or needs guidance on Inversion of Control, DI containers, provider types, and wiring in Python applications.
Design distributed systems using Leslie Lamport's rigorous approach. Emphasizes formal reasoning, logical time, consensus protocols, and state machine replication. Use when building systems where correctness under concurrency and partial failure is critical.
MapStruct Java mapping framework. Covers basic mappers, update mappings, nested objects, collections, custom methods, and Lombok integration. Based on castellino and gestionale-presenze production patterns. USE WHEN: user mentions "mapstruct", "@Mapper", "@Mapping", asks about "DTO mapping", "entity conversion", "@MappingTarget", "nested mapping" DO NOT USE FOR: Java language - use `java` skill instead DO NOT USE FOR: Lombok - use `lombok` skill instead DO NOT USE FOR: JPA entities - use JPA-specific skills

TRIGGER when: user says "environment patching", "module extraction", "run in Node", "webpack module extraction", "environment simulation", "run JS in Node", or needs to run independently without browser after finding the encryption entry. DO NOT TRIGGER when: only debugging in browser, doing AST deobfuscation, or writing ordinary Node.js code.
Apply when deciding where and how a VTEX IO app should store and read data. Covers when to use app settings, configuration apps, Master Data, VBase, VTEX core APIs, or external stores, and how to avoid duplicating sources of truth or abusing configuration stores for operational data. Use for new data flows, caching decisions, refactors, or reviewing suspicious storage and access patterns in VTEX IO apps.
