codex-consult

A command that asks OpenAI Codex for a second opinion on a technical question, plan, debugging idea, or architecture choice. It reads the question and context, then compares Codex's view with the current analysis.

In plain words
What is it for?
Validating implementation plans, challenging debugging hypotheses, comparing technologies, and reviewing architecture decisions without modifying files.
Why use it?
It helps expose overlooked risks, alternatives, and trade-offs before code is changed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

codex-consult scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Consult Codex for a Second Opinion

Get Codex's perspective on a technical question, plan, or approach.

Instructions

You are consulting Codex for a second opinion. This is read-only — no files will be modified.

  1. Parse the question from $ARGUMENTS. This could be:

    • A technical question about the codebase
    • A plan you want validated before implementing
    • An architecture decision you want a second perspective on
    • A debugging hypothesis you want challenged
    • A technology choice comparison
  2. Prepare a focused prompt for Codex. Include:

    • The specific question or plan to evaluate
    • Relevant context: file paths, code snippets, constraints
    • What kind of feedback you want (validation, alternatives, risks, tradeoffs)
  3. Call the codex_exec MCP tool with:

    • prompt: "Provide your analysis and recommendation on the following question. Consider tradeoffs, alternatives, and potential risks. Be specific and cite concrete examples where possible.\n\n"
    • mode: "exec"
  4. Synthesize both perspectives for the user:

    • Present Codex's analysis
    • Provide your own independent analysis
    • Where you agree and why
    • Where you disagree and why (with evidence)
    • Your recommended path forward with reasoning

Important

  • Codex runs in read-only mode — it cannot modify files
  • This is a consultation, not a delegation — the final decision rationale comes from this conversation
  • If you and Codex strongly disagree, present both arguments fairly and let the user decide

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

codex-consult is a command published in the GitHub repository Arystos/skill-codex (5 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 349 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
