What it does
Fresh Library Docs is an agent 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.
Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: 200+ production-ready Claude Code skills for sales, marketing, design, engineering, and AI agent architecture. Built and maintained by OneWave AI. The licence is MIT.
When your agent uses it
- An import fails
- A method does not exist
- A config key is rejected
- A deprecation warning appears
Example prompts
- “/fresh-library-docs”
Requirements
- Python 3
- Node.js
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit fc5b785. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npmpippythonnodenpx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, pip and npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Fresh Library Docs loads about 839 tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 385 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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:
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.
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>))"For a TypeScript project, the .d.ts file answers the question definitively. Read it before searching the web.
Step 3 — Then the Docs
When the source is unreadable or you need usage patterns rather than signatures:
- Official docs for that exact version, not the "latest" URL, which silently redirects.
- The repo's CHANGELOG or migration guide — the fastest way to learn what moved between your mental model and reality.
- GitHub issues for the specific error string, when behavior contradicts the docs.
Blog posts and forum answers are the last resort and always carry a date. A 2023 tutorial for a library that had a major release last year is a trap.
Show full SKILL.md (162 more words)Show less
Step 4 — Confirm Before Committing
For anything non-obvious, run the smallest possible check rather than trusting the read:
node -e "const x=require('<pkg>'); console.log(Object.keys(x).slice(0,30))"
npx tsc --noEmit 2>&1 | head -20Type-check output is the cheapest proof that an API call exists.
Rules
- Never call a method you have not seen defined somewhere real.
- Pin what you learn into the code as a comment only when the behavior is genuinely surprising — not as a version diary.
- When installed and latest differ significantly, say so in one line and let the user decide whether to upgrade. Do not upgrade a dependency to make your snippet work.
- If the answer is genuinely uncertain, say which part is uncertain instead of writing confident code around it.
Highest-Risk Dependencies
Verify these every time; they move fastest and break most: AI SDKs and model identifiers, auth libraries, ORMs and database clients, build tooling and bundler config, meta-framework routing and data-fetching conventions, payment SDKs. For model names, pricing, and parameters specifically, check the provider's current model list rather than recalling one.
