Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

EV / Probability Distribution Honesty Check
對當前持倉執行嚴謹的機率分布與 expected value 計算。強制 first-principles,不接受偷懶輸出。
此 skill 可獨立呼叫做 ad-hoc check,或被其他 skill(briefing / portfolio-review / stock-analysis / todo)在輸出 Verdict / 機率分布前 mandatory 呼叫。
Arguments
/ev-check→ 預設 30 天 horizon/ev-check 7d//ev-check 14d//ev-check 30d→ 自選時間窗/ev-check 30d nvda-bear→ 用戶指定情境主題(agent 會以此為主要 catalyst 反推)
Workflow
Step 1: 收集 raw 輸入
呼叫以下 MCP 取數據(可平行):
mcp__firstrade-server__get_account_position— 持倉mcp__firstrade-server__get_account_balance— 帳戶總值 + 現金mcp__technical-mcp__get_batch_indicators(所有持倉, period=3mo)— RSI / momentum / trendmcp__technical-mcp__get_sector_rotation(period=3mo)— leading / laggingmcp__yfinance-advanced__get_stock_info(top 11 by MV)— 52w high/low、fundamentalsmcp__fmp-mcp__getEarningsCalendar(today, today+horizon)— binary catalysts in window- (平行 agent)
mcp__eodhd-mcp__get_sentiment_trend(top 8 by MV, days=30)— 7d/30d sentiment
Step 2: 整理成 8 項 Input Enumeration
按 probability-honesty-checker agent 的 Step 1 contract,整理:
- 1a. RSI 分布(每個 bucket 檔數 + % of port)
- 1b. 距 52w 高位置(中位數、最大、最小)
- 1c. 已實現波動(5d / 2d / 最大單日)
- 1d. Binary catalysts table(catalyst / 日期 / 影響持倉 % / base rate)
- 1e. 集中度(top 1、top 5、最大板塊)
- 1f. 板塊輪動曝險(leading 持倉 % / lagging 持倉 %)
- 1g. Sentiment 健康度
- 1h. Thesis 健康度(從 plan.md + 近期新聞)
不齊全 → 不能進下一步,必須補齊。
Step 3: 呼叫 probability-honesty-checker subagent
Agent(
subagent_type: "probability-honesty-checker",
description: "EV check for [horizon]",
prompt: """
執行 6 步強制流程計算當前組合 [horizon] 機率分布與 EV。
時間窗: [horizon]
情境主題(如有): [user-specified]
## Step 1 輸入資料(8 項齊全):
[貼上 Step 2 整理好的資料]
## 額外 context:
[plan.md 摘要 / 用戶提到的特定 catalyst / 最近 N 天的事件]
請按你的 6 步流程輸出:
1. Input Enumeration(confirm 我給的齊全)
2. 形狀反推
3. Conditional Probabilities
4. Aggregated Scenario Probabilities
5. EV Calculation
6. Self-Audit Checklist
+ 給主 skill 的精簡輸出
"""
)
Step 4: 顯示 agent 完整輸出
不刪減、不簡化、不重寫。直接呈現 agent 的 6 步流程 + 精簡輸出。
主 skill 看到的格式:
# EV Check — [horizon]
[Agent 完整 6 步輸出]
---
## ✅ 給用戶的精簡結論
機率分布:樂觀 X% / 基準 X% / 悲觀 X%
EV ([horizon]) = X.XX%
主導因素:[1 句]
Step 5: 用戶 push back 處理
如果用戶質疑「你真的有算嗎」「這是 default 嗎」:
- 不要辯解、不要重組原數字
- 重跑 Step 3(重新呼叫 agent,明確要求 audit checklist 全勾)
- 如果發現原本確實偷懶(例如 sum 沒到 100%、機率是 default mirror、EV 寫質性語言)→ 老實承認 + 顯示新算
何時被其他 skill 呼叫
以下 skill 在輸出 Verdict / 機率分布 / EV / Quick Take 之前 必須 呼叫此 skill(或直接 invoke probability-honesty-checker agent):
/briefing(任何 tier)→ Quick Take 前/portfolio-review→ Section K 第一性檢查前/stock-analysis→ 個股 Verdict 前/todo→ 行動清單第一性檢查前
呼叫方式可選:
- 走 ev-check skill(完整流程,給用戶看的格式)
- 直接 invoke
probability-honesty-checkeragent(內部使用,省一層 wrapping)
Output Format
繁體中文。所有數字 explicit。絕不出現:「略偏正」「略偏負」「中性偏多」「應該會」「不確定性高」等質性語言 — 全部換成數字區間或機率。
失敗模式與防呆
| Claude 主程序常見偷懶 | 此 skill 阻擋方式 | |---------------------|----------------| | 套 30/45/25 default | Agent Step 2 強制顯示「形狀規則應用」對照表,不對照不能進 Step 3 | | 寫「略偏負」結論 | Agent Step 5 強制顯式 Σ 計算,數字必須出現 | | 跳過 Step 1 直接給機率 | Agent 收到不完整 input 回「INVALID INPUT」拒絕計算 | | Sum ≠ 100% | Agent Step 4 顯式 sum check | | 中點手動偏移 | Agent Step 5 強制 (max+min)/2 算術平均 |
