| description | Fetch up-to-date documentation and code examples for any library, framework, SDK, CLI tool, or cloud service. Use whenever the user asks about a specific library — even well-known ones like React, Next.js, Prisma, Express, Tailwind, Django, or Spring Boot — because training data may not reflect recent API changes or version updates.
Always use for: API syntax questions, configuration options, version migration issues, "how do I" questions mentioning a library name, debugging that involves library-specific behavior, setup instructions, and CLI tool usage.
Use even when you think you know the answer. Do not rely on training data for API details, signatures, or configuration options — they are frequently out of date. Prefer this over web search for library documentation. |

Context7 Documentation Lookup
Retrieve current documentation and code examples from Context7 using the resolve-library-id and query-docs tools that ship with this extension.
When to use
Reach for these tools whenever a question involves a specific library, framework, SDK, CLI tool, or cloud service. Examples:
- "How do I configure caching in Next.js 16?"
- "What's the syntax for Prisma's
findMany with relations?"
- "Show me a working Tailwind v4 install for a Vite app."
- "How do I rate-limit with
@upstash/ratelimit?"
Workflow
- Resolve the library ID. Call
resolve-library-id with the library name and what to look up in the library's documentation. The tool returns matching libraries with their Context7 IDs (/org/project format), descriptions, snippet counts, and quality scores. Pick the best match — prioritize official sources, name match, and high benchmark scores.
- Query the docs. Call
query-docs with the chosen library ID and what to look up in the library's documentation, scoped to a single concept — if the question spans multiple distinct concepts, make a separate call per concept with the same library ID, unless the question is about how the concepts interact. The tool returns documentation snippets and code examples.
- Answer. Cite the library ID you used and quote code examples verbatim when relevant.
If the user supplies a library ID in /org/project or /org/project/version format directly, skip step 1 and call query-docs immediately.
Constraints
- Do not call either tool more than 3 times per question.
- Do not pass API keys, passwords, credentials, personal data, or proprietary code as the
query argument — it is sent to the Context7 API.
- Authentication uses the
CONTEXT7_API_KEY environment variable. Get a key at https://context7.com/dashboard if requests fail with an auth error.
