fetch-library-docs
Skill8 starsChanged 4 months agoMITView on GitHub
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.

mjunaidcaSkillbrowsing-with-playwright
Browser automation using Playwright MCP. Navigate websites, fill forms, click elements, take screenshots, and extract data. Use when tasks require web browsing, form submission, web scraping, UI testing, or any browser interaction. NOT when only fetching static content (use curl/wget instead).

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
1 rule. About 0 are common, 0 are distinctive, and 1 is very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈0
Distinctive · estimate
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 70
Use python3 on Linux/macOS/WSL, python on Windows:
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
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 userExamples:
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
pythoninstead ofpython3(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.

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
