# Codex Search Skill Use OpenAI Codex CLI with web search capabilities to research current information, documentation, and solutions. This is a **read-only research** skill. ## When to Use - User asks "what's the best library for X?" - User needs current documentation or API references - User wants to compare different libraries or approaches - User has an error message and needs solutions - User asks about best practices or security recommendations - User wants to learn about a new technology or framework - User needs to find tutorials or getting started guides ## Prerequisites Verify Codex CLI is available: ```bash codex --version # Should display installed version ``` **Requirements:** - Internet connectivity for web search - Authenticated Codex access (ChatGPT Plus/Pro/Team/Enterprise or API key in `~/.codex/config.toml`) - Web search enabled in `~/.codex/config.toml` as follows: ```toml [features] web_search_request = true ``` **Note:** The `--search` flag enables Codex's native web search tool. If web search is not available in your environment, the skill will provide information based on the model's training data. ## Basic Usage ### Step 1: Parse the Research Need Extract wh

Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
