Library Documentation Skill

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

WHEN TO INVOKE (Auto-Detection)

INVOKE AUTOMATICALLY when:

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

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>
