developing-features skillA

developing-features is agent-read markdown (skill) from cristhianzl/claude-skills-czl: Write production code with security-first thinking, SOLID design, pragmatic principles, observability, and strict file-structure limits. Use when implementing a new feature, designing a system, refactoring code, or whenever the task is "build production code" rather than fix a bug or write tests. This is the default for feature and production-code work — use it unless the user explicitly asks for TDD (tests-first / red-green-refactor), which is developing-features-tdd. Pairs with ensuring-cross-.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
