fresh-library-docs skillA
fresh-library-docs is agent-read markdown (skill) from onewave-ai/claude-skills: Use before writing code against a library, SDK, API, or framework whose current version you are not certain of — especially fast-moving ones. Trigger when an import fails, a method does not exist, a config key is rejected, a deprecation warning appears, or the user says the code was written against an old version..
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.
What the file says
# Fresh Library Docs Training data has a cutoff; libraries do not. Most "the AI hallucinated an API" bugs are really the model writing correct code for a version that shipped two years ago. This skill checks reality first. ## Core Behavior Before writing non-trivial code against a dependency, establish two facts: which version this project actually has, and what that version's API looks like. In that order. ## Step 1 — What Is Installed The installed version beats the latest version and beats your memory. Read it from the project: ```bash cat package.json | grep -A30 '"dependencies"' npm ls <pkg> --depth=0 2>/dev/null pip show <pkg> 2>/dev/null | head -3 cat requirements.txt pyproject.toml 2>/dev/null | grep -i <pkg> ``` ## Step 2 — Read the Real Source The most reliable documentation is the code on disk. It cannot be out of date, because it is what will run. ```bash ls node_modules/<pkg>/dist/*.d.ts grep -rn "export function <name>\|export declare" node_modules/<pkg>/dist/index.d.ts | head -20 python -c "import <pkg>, inspect; print(inspect.signature(<pkg>.<fn>))" ``` …
Read the whole file at its exact version.
How to install
mdr add onewave-ai/claude-skills/fresh-library-docs@git:20260920.97b5147mdr add onewave-ai/claude-skills/fresh-library-docs@sha256:6e2f1e07d061f644Pin 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.
