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.
Why this skill is useful
Adds specific commands and workflows for managing AI coding skills and configuring Context7 MCP that the AI wouldn't reliably generate on its own.

What this skill does
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: Or run directly without installing: 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 Use when writing code, verifying API signatures, or when training data may be outdated.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 Authentication 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: 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
How to use it
Reference it in AdaL, Claude Code, Cursor or any coding agent — nothing to install:
