verify-second-opinion

verify-second-opinion is a skill for Claude Code from easyinplay/harnessed. It costs 100 tokens per session (1,531 once invoked), scanned A, original, Apache-2.0.

A workflow for getting a second AI review when changes affect the rules and tools that coordinate other workflows.

In plain words
What is it for?
Use it during verification of changes to workflow rules, capabilities, data formats, routing logic, or workflow instructions.
Why use it?
It helps catch problems in core coordination changes while avoiding unnecessary reviews for unrelated work. The review is triggered by checking the changes against defined orchestration files.

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

verify-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 6d 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.

verify-second-opinion workflow (v3)

Overview

1-phase sub-workflow — 编排契约改动时的跨模型第二意见 (Phase 54 T2)。

phase id upstream model capability gate
1 01-second-opinion gstack sonnet {{ capabilities.codex.cmd }} judgments.stage-routing.verify-second-opinion-orchestration.fires

判据不是交给模型的判断题。harnessed factsgit diff --name-only <last release tag> 与 ORCHESTRATION SURFACE (judgments / capabilities / 事实 schema / resolver / exprBuilder / ledger / disciplines / 任一 workflows SKILL.md) 求交集,机械得出 requires_second_opinion

基准是上一个 release tag,不是 merge-base origin/main —— 后者在 commit-即-push-main 的纪律下塌缩成 HEAD,只看得见未提交改动,会漏掉多-commit milestone 的早期 commit。

算不出来 (无 tag / 无 git / diff 失败) 时取 false,并在每轮 <workflow-state> 断点打出 SECOND-OPINION: 判据不可用(<原因>)。不乱 fire,且不静默。

Capability refs

Sister workflows/capabilities.yaml entries:

  • codex — 第二意见 / cross-AI peer review via codex (impl: gstack, cmd: /codex)

Gate ref

Sister workflows/judgments/stage-routing.yaml:

  • verify-second-opinion-orchestration.firesphase.stage == 'verify' and requires_second_opinion == true

Routing rules

  • 触发: 本次改动触及编排契约本身 (judgments / capabilities.yaml / phaseFactContext / facts.ts / judgmentResolver / exprBuilder / ledger.ts / disciplines / 任一 SKILL.md)
  • 跳过: 纯 installer / 文档 / 测试 / 依赖 bump —— 改这些不会改变引擎的决策方式

交付物即证据。 本 sub fire 了就必须交 second-opinion.md;不交则 checkpoint complete fail-closed 阻断,--force 在 ledger 记 evidence_status: overridden。跳过因此是台账上 一行,不是隐形的。

How to invoke

!harnessed checkpoint intent verify-second-opinion

The banner above (when present) means this invocation is REGISTERED with the engine (an intent marker) — not yet compliant: the steps below (prompt → spawn → checkpoint complete) resolve it, and a per-turn <workflow-intent> reminder persists until they run.

The numbered sequence below is the state machine — execute it with Bash. Do NOT improvise an equivalent flow from the Overview above: freelancing bypasses the engine (no ledger, no evidence guard). harnessed gives you the spawn-ready prompt; YOU spawn the subagent with a CC-native Task / Agent tool (keeps the session responsive + lets clarification round-trips reach the user).

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
