Skill Details

SKILL.md

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.

Overview

# 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

```bash

# With known library ID (faster - saves 1 API call)

bash scripts/fetch-docs.sh --library-id --topic "" --content-type

# With library name (auto-resolves)

bash scripts/fetch-docs.sh --library --topic "" --content-type

```

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](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](references/context7-tools.md) for full error handling.
