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

second-opinion 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 5d 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

You are consulting Codex (an OpenAI coding agent running in a sibling session on this machine) for a second opinion. Codex will give independent technical judgment, not passive agreement.

Steps:

  1. Call mcp__hivemind__peers once to confirm Codex is online. If online is false or warnings includes unsupported_session_picker, surface the exact error to the user (with the relaunch hint it returns) and stop.

  2. Send the user's question to Codex via mcp__hivemind__ask_codex with wait_ms: 60000. The tool blocks until Codex finishes the turn or the wait elapses, and returns Codex's reply directly. You do not need to poll afterwards in the normal case.

  3. If ask_codex returns timed_out: true, call mcp__hivemind__wait_for_codex with timeout_ms: 30000 once more before giving up.

  4. Present a concise comparison:

    • Codex's answer: quote the substance.
    • My independent view: state your own reasoning, then explicitly call out where you agree and where you disagree with Codex.
    • Recommendation: one or two sentences synthesizing both views, or a clear flag if the disagreement is unresolved.

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.
