Library Docs Lookup with Context7

What it does

When your agent uses it

• Answering API syntax or configuration questions for a specific library
• Checking the current way to do a task after a library version upgrade
• Finding setup instructions or CLI usage for a framework or SDK
• Debugging behavior that depends on a particular library

Example prompts

• “How do I define one-to-many relations with cascade delete in Prisma? Check the current docs.”
• “Look up how to set up app router middleware in the current Next.js docs.”
• “What changed in the latest Tailwind configuration options?”

Requirements

• Node.js with npm to run ctx7
• Network access to Context7

Workflow steps

2 steps, taken from the step headings in SKILL.md.

1. 1Resolve a Library
2. 2Query Documentation

What it can do on your machine

Read from SKILL.md and the folder at commit f336ed2. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • npm
  • npx

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use npm and npx, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • CONTEXT7_API_KEY

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Library Docs Lookup with Context7 loads about 1.6k tokens when it runs. Until then it costs about 222 tokens; SKILL.md has 620 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~222

When it runs · the whole SKILL.md, loaded when a task matches

~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Retrieves up-to-date documentation, API references, and code examples for any developer technology. Use this skill whenever the user asks about a specific library, framework, SDK, CLI tool, or cloud service -- even for well-known ones like React, Next.js, Prisma, Express, Tailwind, Django, or Spring Boot. Your 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 as they are frequently outdated. Always verify against current docs. Prefer this over web search for library documentation and API details.
