Agent skill

context7-cli

Use the ctx7 CLI to fetch library documentation, manage AI coding skills, and configure Context7 MCP. Activate when the user mentions "ctx7" or "context7", needs current docs for any library, wants to install/search/generate skills, or needs to set up Context7 for their AI coding agent.

SKILL.md

ctx7 CLI

The Context7 CLI does three things: fetches up-to-date library documentation, manages AI coding skills, and sets up Context7 MCP for your editor.

Make sure the CLI is up to date before running commands:

bash
npm install -g ctx7@latest

Or run directly without installing:

bash
npx ctx7@latest <command>

What this skill covers

  • Documentation — Fetch current docs for any library. Use when writing code, verifying API signatures, or when training data may be outdated.
  • Skills management — Install, search, suggest, list, remove, and generate AI coding skills.
  • Setup — Configure Context7 MCP for Claude Code / Cursor / OpenCode.

Quick Reference

bash
# Documentation
ctx7 library <name> <query>           # Step 1: resolve library ID
ctx7 docs <libraryId> <query>         # Step 2: fetch docs

# Skills
ctx7 skills install /owner/repo       # Install from a repo (interactive)
ctx7 skills install /owner/repo name  # Install a specific skill
ctx7 skills search <keywords>         # Search the registry
ctx7 skills suggest                   # Auto-suggest based on project deps
ctx7 skills list                      # List installed skills
ctx7 skills remove <name>             # Uninstall a skill
ctx7 skills generate                  # Generate a custom skill with AI (requires login)

# Setup
ctx7 setup                            # Configure Context7 MCP (interactive)
ctx7 login                            # Log in for higher rate limits + skill generation
ctx7 whoami                           # Check current login status

Authentication

bash
ctx7 login               # Opens browser for OAuth
ctx7 login --no-browser  # Prints URL instead of opening browser
ctx7 logout              # Clear stored tokens
ctx7 whoami              # Show current login status (name + email)

Most commands work without login. Exceptions: skills generate always requires it; ctx7 setup requires it unless --api-key or --oauth is passed. Login also unlocks higher rate limits on docs commands.

Set an API key via environment variable to skip interactive login entirely:

bash
export CONTEXT7_API_KEY=your_key

Common Mistakes

  • Library IDs require a / prefix — /facebook/react not facebook/react
  • Always run ctx7 library first — ctx7 docs react "hooks" will fail without a valid ID
  • Repository format for skills is /owner/repo — e.g., ctx7 skills install /anthropics/skills
  • skills generate requires login — run ctx7 login first

ai-elements

Build AI chat interfaces using ai-elements components — conversations, messages, tool displays, prompt inputs, and more. Use when the user wants to build a chatbot, AI assistant UI, or any AI-powered chat interface.

opensrc

Fetch dependency source code to give AI agents deeper implementation context. Use when the agent needs to understand how a library works internally, read source code for a package, fetch implementation details for a dependency, or explore how an npm/PyPI/crates.io package is built. Triggers include "fetch source for", "read the source of", "how does X work internally", "get the implementation of", "opensrc path", or any task requiring access to dependency source code beyond types and docs.

dogfood

Systematically explore and test a web application to find bugs, UX issues, and other problems. Use when asked to "dogfood", "QA", "exploratory test", "find issues", "bug hunt", "test this app/site/platform", or review the quality of a web application. Produces a structured report with full reproduction evidence -- step-by-step screenshots, repro videos, and detailed repro steps for every issue -- so findings can be handed directly to the responsible teams.

minimax-pdf

Use this skill when visual quality and design identity matter for a PDF. CREATE (generate from scratch): "make a PDF", "generate a report", "write a proposal", "create a resume", "beautiful PDF", "professional document", "cover page", "polished PDF", "client-ready document". FILL (complete form fields): "fill in the form", "fill out this PDF", "complete the form fields", "write values into PDF", "what fields does this PDF have". REFORMAT (apply design to an existing doc): "reformat this document", "apply our style", "convert this Markdown/text to PDF", "make this doc look good", "re-style this PDF". This skill uses a token-based design system: color, typography, and spacing are derived from the document type and flow through every page. The output is print-ready. Prefer this skill when appearance matters, not just when any PDF output is needed.

get-api-docs

Use this skill when you need documentation for a third-party library, SDK, or API before writing code that uses it — for example, "use the OpenAI API", "call the Stripe API", "use the Anthropic SDK", "query Pinecone", or any time the user asks you to write code against an external service and you need current API reference. Fetch the docs with chub before answering, rather than relying on training knowledge.
