codex-ask
Ask OpenAI Codex questions about code to understand implementations, architecture, patterns, and debugging. Use when the user asks how code works, where something is implemented, what patterns are used, or needs to understand existing code. Requires Codex CLI installed.
npx skills add majiayu000/claude-skill-registry --skill codex-ask-dceoy-gh-actions-for-devop --agent codex
Same command for any agent — swap --agent for claude-code, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Codex Ask Skill Use OpenAI Codex CLI to answer questions about code without making modifications. This is a **read-only** analysis skill. ## When to Use - User asks "how does X work?" - User wants to find where something is implemented - User needs to understand architecture or patterns - User is debugging and needs to understand code flow - User asks "what does this code do?" ## Prerequisites Verify Codex CLI is available: ```bash codex --version # Should display installed version ``` ## Basic Usage ### Step 1: Parse the Question Extract what the user wants to know. Good questions include: - File/component context - Specific functionality - Desired answer format ### Step 2: Execute Codex Query Run Codex in read-only mode: ```bash codex --sandbox=read-only exec "Answer this question about the codebase: [QUESTION] Provide: 1. Direct answer to the question 2. Specific file paths and line numbers 3. Code examples from the actual codebase 4. Related concepts or dependencies Do NOT make any changes - this is read-only analysis." ``` ### Step 3: Present Answer Format the response with: - **Summary**: 1-2 sentence direct answer - **Details**: In-depth explanation - **File References**:

What does the codex-ask skill do?
Ask OpenAI Codex questions about code to understand implementations, architecture, patterns, and debugging. Use when the user asks how code works, where something is implemented, what patterns are used, or needs to understand existing code. Requires Codex CLI installed.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill codex-ask-dceoy-gh-actions-for-devop --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
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.
