2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
6 stars6 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Fetches official documentation for external libraries and frameworks (React, Next.js, Prisma, FastAPI, Express, Tailwind, MongoDB, etc.) with 60-90% token savings via content-type filtering. Use this skill when implementing features using library APIs, debugging library-specific errors, troubleshooting configuration issues, installing or setting up frameworks, integrating third-party packages, upgrading between library versions, or looking up correct API patterns and best practices. Triggers automatically during coding work - fetch docs before writing library code to get correct patterns, not after guessing wrong.

Library Documentation Skill

Fetches official library documentation with 60-90% token savings.

WHEN TO INVOKE (Auto-Detection)

INVOKE AUTOMATICALLY when:

Context	Detection Signal	Content Type
Implementing	About to write code using library API	`examples,api-ref`
Debugging	Error contains library name (e.g., `PrismaClientError`)	`troubleshooting`
Installing	Adding new package, `npm install`, setup task	`setup`
Integrating	Connecting libraries ("use X with Y")	`examples,setup`
Upgrading	Version migration, breaking changes	`migration`
Uncertain	First use of library feature, unsure of pattern	`examples`

DO NOT INVOKE when:

Already have sufficient knowledge from training
User pasted docs or has them open
Task is about local/private code (use codebase search)
Comparing libraries (use web search)

DECISION LOGIC

1. Identify Library

Priority: User mention → Error message → File imports → package.json → Ask user

Examples:

PrismaClientKnownRequestError → library = "prisma"
import { useState } from 'react' → library = "react"
from fastapi import FastAPI → library = "fastapi"

2. Identify Topic

Priority: User specifies → Error message → Feature being implemented → "getting started"

3. Select Content Type

Task	Content Type
Implementing code	`examples,api-ref`
Debugging error	`troubleshooting,examples`
Installing/setup	`setup`
Integrating libs	`examples,setup`
Upgrading version	`migration`
Understanding why	`concepts`
Best practices	`patterns`

EXECUTION

IMPORTANT: Always use the Python entry point (fetch-docs.py) for cross-platform compatibility.

Use python3 on Linux/macOS/WSL, python on Windows:

# With known library ID (faster - saves 1 API call)
python3 scripts/fetch-docs.py --library-id <id> --topic "<topic>" --content-type <types>

# With library name (auto-resolves)
python3 scripts/fetch-docs.py --library <name> --topic "<topic>" --content-type <types>

Windows note: Use python instead of python3 (e.g., python scripts/fetch-docs.py ...)

Quick Library IDs

Library	ID
React	`/reactjs/react.dev`
Next.js	`/vercel/next.js`
Prisma	`/prisma/docs`
Tailwind	`/tailwindlabs/tailwindcss.com`
FastAPI	`/tiangolo/fastapi`

See references/library-ids.md for complete list.

ERROR HANDLING (Quick Reference)

Error	Action
`[LIBRARY_NOT_FOUND]`	Try spelling variations
`[LIBRARY_MISMATCH]`	Use --library-id directly
`[EMPTY_RESULTS]`	Broaden topic or use `--content-type all`
`[RATE_LIMIT_ERROR]`	Check API key setup

Call Budget: Context7 allows 3 calls/question. Use --library-id to save 1 call.

See references/context7-tools.md for full error handling.
