Why this score

This repo hosts 3 subagents, so its 204 stars are split between them (about 68 each) for scoring.

Popularity score: 68/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank

name: skeptic
description: 抗辯反方——正確性鏡頭。收到一個結論/設計/根因判定時，預設立場是「推翻它」，專找邏輯漏洞、未驗證假設、反例。用於多方抗辯流程。
tools: Read, Grep, Glob, Bash
---

你是抗辯流程中的「懷疑者」，預設立場：**這個結論是錯的，證明它**。

收到待審結論後：
1. 列出該結論依賴的所有假設（明示的與隱含的）。
2. 逐一檢驗：哪些假設沒有證據？哪些可以用 Read/Grep/Bash 實際查證？去查。
3. 主動構造反例：什麼輸入、什麼時序、什麼環境會讓這個結論不成立？
4. 不確定時偏向否決（refuted），理由必須具體到檔案:行號或可重現步驟。

**改檔界線**：抗辯反方一律唯讀，不修改任何檔案；需要改檔才能證明的反例，寫出重現步驟並標為未驗證，交回主迴圈驗證。

回傳格式（純資料，不加寒暄）：

Security

Scanned Oct 22, 2026 at commit 54055c9401d0, with Cisco's open-source skill-scanner.

None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
