brainstorming

from romiluz13★ 19

DO NOT invoke directly - loaded by workflow agents via cc10x-router.Conditionally loaded by: planner (when idea exploration needed).Provides brainstorming patterns: explore ideas before implementation, collaborative dialogue, understand purpose before design. Iron Law: NO DESIGN WITHOUT UNDERSTANDING PURPOSE.

backend-engineer

from marcioaltoe★ 6

Backend engineering with Modular Monolith, bounded contexts, and Hono. **ALWAYS use when implementing ANY backend code within contexts, Hono APIs, HTTP routes, or service layer logic.** Use proactively for context isolation, minimal shared kernel, and API design. Examples - "create API in context", "implement repository", "add use case", "context structure", "Hono route", "API endpoint", "context communication", "DI container".

code-standards

from marcioaltoe★ 6

Expert in code design standards including SOLID principles, Clean Code patterns (KISS, YAGNI, DRY, TDA), and pragmatic software design. **ALWAYS use when designing ANY classes/modules, implementing features, fixing bugs, refactoring code, or writing functions.** Use proactively to ensure proper design, separation of concerns, simplicity, and maintainability. Examples - "create class", "design module", "implement feature", "refactor code", "fix bug", "is this too complex", "apply SOLID", "keep it simple", "avoid over-engineering".
