developing-features skillA

developing-features is agent-read markdown (skill) from cristhianzl/claude-skills-czl: Write production code in Langflow with security-first thinking, SOLID design, pragmatic principles, observability, and strict file-structure limits — tuned for Langflow conventions (uv workspaces, SQLModel, lfx vs langflow-base split, pre-commit invoked via uv run). Use when implementing a new feature, designing a service, refactoring backend code, adding an API route, or whenever the task is "build production code" rather than fix a bug or write tests. This is the default for feature and produc.

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.
