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 10d 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

Second-Opinion — ULTRON Skill

This is a starter template for the second-opinion skill. Edit freely.

When to use

(Describe the triggers this skill should match. Activate when the user asks for a second opinion, external review, codex review, gemini review, or mentions /second-opinion on uncommitted changes, branch diffs, or specific commits.)

Workflow

  1. (First step — pick the right peer model (Codex for iteration, Gemini for long-context / 150+ file reviews).)
  2. (Second step — run the review and capture output to a subagent file.)
  3. (Final output expectation — concise findings with prioritized actions.)

Changes

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.
