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.

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

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

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

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.
