oracle-codex
This skill should be used when the user asks to "use Codex", "ask Codex", "consult Codex", "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 NOT for implementation tasks.
npx skills add majiayu000/claude-skill-registry --skill oracle-codex-paulrberg-agent-skills --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 Oracle Use OpenAI Codex CLI as a **read-only oracle** — planning, review, and analysis only. Codex provides its perspective; you synthesize and present results to the user. **Sandbox is always `read-only`**. Codex must never implement changes. ## Arguments Parse `$ARGUMENTS` for: - **query** — the main question or task (everything not a flag). **Required** — if empty, tell the user to provide a query and stop. - `--reasoning <level>` — override reasoning effort (`low`, `medium`, `high`, `xhigh`). Optional; default is auto-selected based on complexity. ## Prerequisites Run the check script before any Codex invocation: ```bash scripts/check-codex.sh ``` If it exits non-zero, display the error and stop. Use the wrapper for all `codex exec` calls: ```bash scripts/run-codex-exec.sh ``` ## Configuration | Setting | Default | Override | | --------- | --------------- | ------------------------------------------------ | | Model | `gpt-5.3-codex` | Allowlist only (see `references/codex-flags.md`) | | Reasoning | Auto | `--reasoning <level>` or user prose | | Sandbox | `read-only` | Not overridable | ### Reasoning Effort | Complexity | Effort | Timeout | Criteria | | ---------- | ----

What does the oracle-codex skill do?
This skill should be used when the user asks to "use Codex", "ask Codex", "consult Codex", "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 NOT for implementation tasks.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-paulrberg-agent-skills --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.
