Create, evolve, and ship Langflow Components — the building blocks of every flow. Use when the user asks to "create a component", "add a provider component", "build an LLM component", "add Anthropic / OpenAI / Chroma / etc. integration", "expose this as a Component", or "wrap this LangChain class as a Component". Enforces the immutable-class-name rule, the inputs/outputs API, the hot-reload workflow, ComponentTestBase fixtures, and the bundle-vs-base placement decision. For refactoring an…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Building Langflow Components A Langflow Component is a Python class that becomes a draggable node in the visual flow editor. Every component is a contract between the flow JSON (which references the class by name) and the runtime (which loads and executes it). Get the contract right and the component lasts forever; get it wrong and you break saved flows for every user who ever used it. ## Read first (always) List `learnings/` and read every file relevant to the current component (provider, bundle, AI runtime, etc.). Project-specific naming conventions, banned dependencies, icon rules, or provider-specific patterns live there and override the defaults in this SKILL.md. If a learning conflicts with this file, **the learning wins** — mention it to the user. Also read `AGENTS.md` at the Langflow repo root — it's canonical and may have evolved. ## Tradeoff — when to apply, when to lighten up Apply the full discipline (immutable name, full test suite with `ComponentTestBaseWith[out]Client`, ADR for non-obvious design, BUNDLE_API changelog when relevant) for **every new component that ships**. …

How to install
mdr add cristhianzl/claude-skills-czl/building-langflow-components@sha256:3c1e66031336d859The line at the top of this page pins the label git:20261103.b450fa3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
