About

Fetch up-to-date library documentation via Context7 CLI

Context7 is a codex skill — a focused instruction set the agent loads when you need specialized coding help. Skills are lighter than full plugins and install with the --skill flag.

Source package path: am-will/codex-skills/skills/ctx7old on GitHub (am-will/codex-skills).

Key features

  • Specialized agent instructions for coding tasks
  • Lighter than a full plugin — focused playbook the agent loads on demand
  • Install with the --skill flag via npx
  • Ideal when you want Context7 expertise without a full integration

How to install

  1. 01

    Copy the install command

    Use the command on this page — it includes the correct --skill flag for this skill.

  2. 02

    Run it in your project terminal

    Execute the command from the directory where you use Codex, not necessarily your home folder.

  3. 03

    Restart or reload Codex

    Restart the Codex CLI or reload your IDE window so the new extension is picked up.

  4. 04

    Try an example prompt

    Ask Codex something related to Context7 to confirm the skill is active.

Example prompts

Try these after installing to confirm Context7 is working.

> Invoke the Context7 skill to review this code change
> Use Context7 workflows for the task I'm working on now
> When should I use the Context7 skill versus a general prompt?
