utility-components

What problem does it solve?

BK-CI teams often duplicate small utility implementations across projects. This Skill provides a centralized set of reusable utility components for core concerns like security, dynamic expression evaluation, threading utilities, and flexible request processing.

Core Features & Use Cases

• JWT Security: token generation, validation, refresh workflows, and OAuth2 integration for service-to-service authentication.
• Expression Parser: dynamic variable substitution and conditional logic to drive pipeline decisions.
• Thread Pool & Loop Utilities: MDC-friendly thread pools for asynchronous tasks and robust looping/retry helpers.
• Chain of Responsibility: interceptors and pipelines enabling modular, extensible request handling.

Quick Start

Start by reviewing reference/1-jwt-security.md for authentication patterns, reference/2-expression-parser.md for dynamic evaluation, reference/3-thread-pool-loop-util.md for concurrency helpers, and reference/4-chain-responsibility.md for chaining patterns.
