developing-features-tdd skillA

developing-features-tdd is agent-read markdown (skill) from cristhianzl/claude-skills-czl: Build a Langflow feature with strict TDD — UNDERSTAND → DESIGN → RED → VERIFY RED → GREEN → VERIFY GREEN → REFACTOR → VALIDATE → REPEAT — applying Langflow's prefer-real-integrations-over-mocks policy, ComponentTestBase fixtures, and the graph test pattern from AGENTS.md. Use when building a new feature with TDD, when the user says "TDD this", "tests first", "red green refactor", or asks for feature work in Langflow that needs to be verifiable from the spec. For bug fixes use fixing-bugs; for no.

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
