Second Opinion

---
name: second-opinion
description: Use when asked to get a second opinion on a finished DRAFT, fact-check or double-check a report's claims against its evidence, sanity-check before sign-off, or red-team an output for fabrication / overreach / invented IDs — even without the word "honesty". Works on an agentic-sop-kit run dir (FULL, uses the run's trace) or any plain document (DEGRADED, you supply the inputs). ｜ 要對一份已完成的 DRAFT 取得「第二意見」、在核准前查核報告主張是否有輸入佐證、抓臆造／灌水／過度宣稱／捏造編號時使用；吃 agentic-sop-kit 的 run 目錄（FULL，用 trace）或任何純文件（DEGRADED，需自備輸入）。不適用：稽核 agent 架構有沒有拆好／是不是 mega-agent（改用 agentic-workflow-audit）；審查原始碼品質／bug／資安（改用 /code-review）。本 skill 只查「這次產出的主張 vs. 證據」誠實度，只產 DRAFT，核准永遠人擁有。

# Second Opinion — adversarial honesty reviewer

An **independent, skeptical second reader** for a finished DRAFT. It checks whether every
claim is backed by its evidence and hands back a findings report — which is itself a DRAFT.
A human decides.

## When to use / not use
- **Use** when: "get a second opinion on this report", "is this draft trustworthy / honest",
  "double-check the numbers before I sign", "red-team this output", "did it make anything up?"
- **Not** for **architecture** ("is my workflow decomposed / a mega-agent?") → `agentic-workflow-audit`.
- **Not** for **source-code quality / bugs / security** → `/code-review`, `/security-review`.
  Second Opinion reads a **produced artifact's claims vs its cited evidence**, in any domain.

## What it catches (domain-neutral)
- **#1** wrong PASS/FAIL or spec-limit verdicts, and aggregates that don't recompute.
- **#2** numbers with no matching source token (fabrication / transcription error).
- **#3** invented identifiers / dates / names with no provenance (should be `【待補】`).
- **#4** conclusions the data don't support (overreach) — advisory.

## How it works (two layers; the guarantees are in CODE, not this prose)
1. **Deterministic layer** (stdlib, hermetic): catches `#1/#2/#3`. In FULL mode these are
   **HARD** at confidence 1.0 (the kit `trace` is authoritative); in DEGRADED mode they are
   **SOFT** at 0.5 (provenance reconstructed from supplied inputs).
2. **Advisory LLM layer** (you): catches `#4` and fuzzy `#1`. It is **capped**
   (`SECONDOP_MAX_LLM_PASSES`, default 1) and every finding is **clamped to SOFT / advisory /
   confidence ≤ 0.5**, **dropped** unless it cites a verbatim draft span (or `NO SOURCE`), and
   **suppressed** if it re-litigates a slot the deterministic layer already settled.

## To run it
Invoke the **`/second-opinion`** command, which orchestrates the deterministic pass → your
capped advisory pass → the code-enforced fold-in → the human STOP. Modes:
- `/second-opinion <run_dir>` — FULL (an agentic-sop-kit run dir)
- `/second-opinion <doc> --inputs <file...>` — DEGRADED (any document)
- `/second-opinion` — the bundled cross-domain demo

## Iron rules
- Facts only from inputs; unknowns are `【待補】`; never invent numbers / IDs / dates / conclusions
  — and the red-team itself may not invent **accusations** (the evidence gate enforces this).
- The deterministic checks are the only HARD signal; the LLM pass is advisory + capped, **in code**.
- The report is a **DRAFT**. A human owns approve / reject. Never auto-approve, never auto-file.
- Real enforcement lives in the code (clamp / evidence-gate / cap) and the optional Stop-hook —
  not in this prose.
