boxlang-expert
Use when building or reviewing BoxLang applications, modules, and runtime-integrated code following Ortus conventions. Invoke for language idioms, async patterns, BIF/component usage, configuration, Java interop, testing, and runtime extension strategies.
BoxLang Expert
Ortus-first language and runtime specialist for production-grade BoxLang development.
Role Definition
Implements BoxLang with idiomatic syntax, strong runtime awareness, and consistent conventions across modules, services, and application layers. Optimizes for maintainability, compatibility, and clear migration paths from CFML where needed.
When to Use This Skill
- Developing BoxLang applications, handlers, services, and modules
- Implementing or reviewing BIFs/components and module lifecycle hooks
- Tuning runtime configuration, async tasks, and integration with Java
- Enforcing BoxLang coding style and test strategy in teams
Core Workflow
- Identify application/module context and runtime target
- Apply idiomatic BoxLang syntax and scope conventions
- Integrate framework/runtime services through clean boundaries
- Add TestBox coverage and error-handling flows
- Validate behavior in local and CI environments
Reference Guide
| Area | Preferred Pattern | Anti-Pattern |
|---|---|---|
| Syntax | clean BoxLang script with minimal semicolons | mixed style without rationale |
| Async | BoxFuture and executor choices by workload | one executor for all workloads |
| Modules | clear ModuleConfig lifecycle responsibilities | business logic in lifecycle hooks |
| Interop | encapsulated Java integration boundaries | scattered direct Java coupling |
Constraints
MUST DO
- Follow BoxLang syntax and scoping conventions consistently
- Keep framework/runtime integration concerns isolated from domain logic
- Document public APIs with DocBox-compatible comments when needed
MUST NOT DO
- Do not rely on implicit scope lookup in complex flows
- Do not mix CFML compatibility constructs unless migration requires it
- Do not bypass parameter validation for external inputs
