+# Codex Integration for Claude Code
+
+<img width="2288" height="808" alt="skillcodex" src="https://github.com/user-attachments/assets/85336a9f-4680-479e-b3fe-d6a68cadc051" />
+
+
+## Purpose
+Enable Claude Code to invoke the Codex CLI (`codex exec` and session resumes) for automated code analysis, refactoring, and editing workflows.
+
+## Prerequisites
+- `codex` CLI installed and available on `PATH`.
+- Codex configured with valid credentials and settings.
+- Confirm the installation by running `codex --version`; resolve any errors before using the skill.
+
+## Installation
+
+Download this repo and store the skill in ~/.claude/skills/codex
+
+```
+git clone --depth 1 git@github.com:skills-directory/skill-codex.git /tmp/skills-temp && \
+mkdir -p ~/.claude/skills && \
+cp -r /tmp/skills-temp/ ~/.claude/skills/codex && \
+rm -rf /tmp/skills-temp
+```
+
+## Usage
+
+### Important: Thinking Tokens
+By default, this skill suppresses thinking tokens (stderr output) using `2>/dev/null` to avoid bloating Claude Code's context window. If you want to see the thinking tokens for debugging or insight into Codex's reasoning process, explicitly ask Claude to show them.
+
+### Example Workflow
+
+**User prompt:**
+```
+Use codex to analyze this repository and suggest improvements for my claude code skill.
+```
+
+**Claude Code response:**
+Claude will activate the Codex skill and:
+1. Ask which model to use (`gpt-5` or `gpt-5-codex`) unless already specified in your prompt.
+2. Ask which reasoning effort level (`low`, `medium`, or `high`) unless already specified in your prompt.
+3. Select appropriate sandbox mode (defaults to `read-only` for analysis)
+4. Run a command like:
+```bash
+codex exec -m gpt-5-codex \
+  --config model_reasoning_effort="high" \
+  --sandbox read-only \
+  --full-auto \
+  --skip-git-repo-check \
+  "Analyze this Claude Code skill repository comprehensively..." 2>/dev/null
+```
+
+**Result:**
+Claude will summarize the Codex analysis output, highlighting key suggestions and asking if you'd like to continue with follow-up actions.
