From the SKILL.md

# Codex Oracle Use OpenAI Codex CLI as a **planning oracle** and **code reviewer**. Codex provides analysis and recommendations; Claude synthesizes and presents to the user. **Critical**: This skill is for planning and review ONLY. Never use Codex to implement changes. ## Prerequisites Before invoking Codex, validate availability: ```bash ~/.claude/skills/oracle-codex/scripts/check-codex.sh ``` If the script exits non-zero, display the error message and stop. Do not proceed without Codex CLI. ## Configuration Defaults | Setting | Default | User Override | | --------- | ----------------------------- | ----------------------------------------------- | | Model | `gpt-5.2-codex` | "use model X" or "with gpt-5.2-codex" | | Reasoning | Dynamic (based on complexity) | "use medium reasoning" or "with xhigh effort" | | Sandbox | `read-only` | Not overridable (safety constraint) | | Timeout | 5 minutes minimum | Estimate based on task complexity | | Profile | `quiet` (notify=[]) | User opts into another profile or notifications | ### Timeout Guidelines When invoking `codex exec` via the Bash tool, always set an appropriate timeout: - **Minimum**: 5 minutes (300000ms) for any Codex operation

About this skill
What does the oracle-codex skill do?

This skill should be used when the user asks to "use Codex", "ask Codex", "consult Codex", "Codex review", "use GPT for planning", "ask GPT to review", "get GPT's opinion", "what does GPT think", "second opinion on code", "consult the oracle", "ask the oracle", or mentions using an AI oracle for planning or code review. NOT for implementation tasks.

How do I install it?

Run `npx skills add majiayu000/claude-skill-registry --skill oracle-codex --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.
