Invokes OpenAI Codex CLI as read-only oracle for code planning, review, and analysis. Activates on 'ask Codex', 'consult oracle', or AI planning/review requests.

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.
Guides Next.js Cache Components and Partial Prerendering (PPR) with cacheComponents enabled. Implements 'use cache', cacheLife(), cacheTag(), revalidateTag(), static/dynamic optimization, and cache debugging.
Guides building MCP servers enabling LLMs to interact with external services via tools. Covers best practices, TypeScript/Node (MCP SDK), Python (FastMCP).
Generates original PNG/PDF visual art via design philosophy manifestos for posters, graphics, and static designs on user request.
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.
Parse $ARGUMENTS for:
--reasoning <level> — override reasoning effort (low, medium, high, xhigh). Optional; default is xhigh.Run the check script before any Codex invocation:
scripts/check-codex.sh
If it exits non-zero, display the error and stop. Use the wrapper for all codex exec calls:
scripts/run-codex-exec.sh
| Setting | Default | Override |
|---|---|---|
| Model | gpt-5.4 | Allowlist only (see references/codex-flags.md) |
| Reasoning | xhigh | --reasoning <level> or user prose |
| Sandbox | read-only | Not overridable |
| Complexity | Effort | Timeout | Criteria |
|---|---|---|---|
| Simple | low | 300000ms | <3 files, quick question |
| Moderate | medium | 300000ms | 3–10 files, focused analysis |
| Complex | high | 600000ms | Multi-module, architectural thinking |
| Maximum | xhigh | 600000ms | Full codebase, critical decisions |
For xhigh tasks that may exceed 10 minutes, use run_in_background: true on the Bash tool and set CODEX_OUTPUT so you can read the output later.
See references/codex-flags.md for full flag documentation.
$ARGUMENTS for query and --reasoningscripts/check-codex.sh — abort on failurexhigh reasoning effort unless --reasoning overrides itBuild a focused prompt from the user's query and any relevant context (diffs, file contents, prior conversation). Keep it direct — state what you want Codex to analyze and what kind of output you need. Do not implement; request analysis and recommendations only.
Invoke via the wrapper with HEREDOC. Set the Bash tool timeout per the reasoning effort table above.
EFFORT="<effort>" \
CODEX_OUTPUT="/tmp/codex-${RANDOM}${RANDOM}.txt" \
scripts/run-codex-exec.sh <<'EOF'
[constructed prompt]
EOF
For xhigh, consider run_in_background: true on the Bash tool call, then read CODEX_OUTPUT when done.
Read the output file and present with attribution:
