+## P6 — Scenario playbooks + confirm-before-post
+
+**Capability:** reusable **scenario playbooks** for Grok Bot–style acceptance — not a single vertical hardcode.
+
+Pattern:
+
+1. **Phase A** — research + draft on a source portal (**no** irreversible publish)
+2. Human only for: auth `browser_handoff` + final confirm
+3. **Phase B** — publish to target channel **only** after explicit approval
+
+**Product primitive:** `request_user_confirm` (bilingual stdin gate; `GROKBOY_CONFIRM_AUTO` for tests, falls back to `GROKBOY_HANDOFF_AUTO`). AGENT_SYSTEM forbids irreversible public social posts without (a) explicit user approval this turn of the exact draft, or (b) confirm → approved. Prefer draft → confirm → act; prefer `browser_handoff` only for auth walls.
+
+**Docs:** [`docs/scenarios/README.md`](scenarios/README.md) (可推廣 pattern), [`docs/SCENARIO-TEMPLATE.md`](SCENARIO-TEMPLATE.md), `prompts/templates/`.
+
+**Example only (範例，非唯一路徑):** Shopee Affiliate → Threads — [`docs/scenarios/examples/shopee-threads-affiliate.md`](scenarios/examples/shopee-threads-affiliate.md) + `prompts/examples/shopee-threads-phase-*.txt`.

+- Falls back to `GROKBOY_HANDOFF_AUTO` when CONFIRM_AUTO unset
+- `GROKBOY_BROWSER_HEADED=1` — required for real cookie/auth scenarios
+
+### Acceptance (summary)
+

 ## Roadmap hint (later)
 
-P6+ may deepen session UX, richer browser persistence across process restarts, or more tools — still thin core, DOM-first browser.

+# Scenario playbooks（情境劇本）— 可推廣的 GrokBoy 驗收模式
+
+本目錄描述 **可重複套用** 的 acceptance playbook：把「研究來源 → 草稿 → 人工確認 → 發佈到目標頻道」做成固定兩階段流程。  
+**蝦皮聯盟 → Threads** 只是一個填好的範例，不是唯一路徑。
+
+產品原語（讓所有情境可推廣）：
+
+| 原語 | 用途 |
+|------|------|
+| `browser_handoff` | 僅用於登入／OTP／驗證碼牆 |
+| `request_user_confirm` | 任何不可逆公開動作（發文、送出）前必須過關 |
+| Phase A / Phase B | 研究+草稿 vs 確認後才發佈 |
+
+相關：[`docs/SCENARIO-TEMPLATE.md`](../SCENARIO-TEMPLATE.md)、[`prompts/templates/`](../../prompts/templates/)、範例 [`examples/shopee-threads-affiliate.md`](examples/shopee-threads-affiliate.md)。
+
+---
+
+## 目標與成功標準
+
+### 過（Pass）
+
+1. **端到端完成**：從來源入口找到可用素材／連結，產出目標頻道草稿，經確認後成功發佈（或明確 blocked）。
+2. **人工觸點最小化**：理想上只有  
+   (1) 來源站登入 handoff  
+   (2) 目標頻道登入 handoff  
+   (3) 最終發佈 confirm  
+   — 其餘自動化。
+3. **零靜默發佈**：沒有「本輪明確核准的草稿」或 `request_user_confirm` → `approved`，就不得 publish／send。
+4. **Phase 分離**：Phase A **禁止**發佈；Phase B **只**在核准後發佈。
+
+### 不過（Fail）
+
+- 未確認就發文／按送出  
+- 非 headed 導致 cookie 遺失、無限重登  
+- 列表／空結果空轉（loop guard 觸發仍算流程失敗若未 `report_blocked` 說明）  
+- 把登入以外的事丟給人（例如叫人手動複製貼上整篇文，而非 agent 貼上後只等 confirm）
+
+---
+
+## Phase A — 研究 + 草稿（禁止發佈）
+
+1. 若需登入來源：`browser_handoff`（僅 auth）。
+2. 在 `{{SOURCE_PORTAL}}` 依 `{{GOAL}}` 找出約 2–5 個候選（高佣／相關／可分享）。
+3. （可選）快速看 `{{TARGET_CHANNEL}}` 語氣／近期風格。
+4. 用繁中（或指定語言）起草 **1** 則貼文，含連結；結構化輸出候選 + 草稿。
+5. `report_done` — **禁止** click send／publish。
+
+## Phase B — 僅在確認後發佈
+
+1. 僅在本 session 已有「明確核准的同一草稿」，或先呼叫 `request_user_confirm`（`prompt` = 全文草稿）。
+2. 若需登入目標頻道：`browser_handoff`。
+3. 貼上並發佈已核准草稿。
+4. `report_done`（盡量附貼文 URL）；若未核准 → `report_blocked`，**不得**單方面發文。
+
+---
+
+## 環境與指令
+
+```bash
+export GROKBOY_API_KEY=你的金鑰
+export GROKBOY_BROWSER_HEADED=1   # 強烈建議；否則 cookie／session 易丟
+cd ~/GrokBoy
+cargo run -p grokboy -- agent
+```
+
+測試用：`GROKBOY_CONFIRM_AUTO=1`（核准）／`abort`（拒絕）；亦可沿用 `GROKBOY_HANDOFF_AUTO`。
+
+### 如何貼 prompts
+
+1. 複製 `prompts/templates/phase-a.txt`，替換 `{{SOURCE_PORTAL}}`、`{{TARGET_CHANNEL}}`、`{{GOAL}}`、`{{CONSTRAINTS}}`。  
+2. 貼進 `grokboy agent` 當本輪 user 訊息。  
+3. 審草稿後，再貼 Phase B（或直接在聊天寫「核准，請發佈以下草稿：…」）。
+
+填好的範例見 `prompts/examples/`。
+

+
+## 如何實例化新情境
+
+填寫模板欄位即可，例如：
+
+| 欄位 | 意義 | 範例 |
+|------|------|------|
+| `SOURCE_PORTAL` | 研究／取連結的站 | affiliate.shopee.tw、某官網活動頁 |
+| `TARGET_CHANNEL` | 發佈目標 | Threads、FB、IG、X |
+| `GOAL` | 成功長相 | 高佣商品約 3 個、季節主題 |
+| `CONSTRAINTS` | 額外限制 | 語氣、禁用詞、長度、必須含 #tag |
+| `LANGUAGE` | 草稿語言 | 繁體中文 |
+
+步驟：複製 template → 填 placeholder → 存成 `docs/scenarios/examples/<name>.md` + `prompts/examples/<name>-phase-{a,b}.txt` → 用 `agent` 跑驗收。
+
+---
+
+## 失敗模式速查
+
+| 現象 | 處置 |
+|------|------|
+| Headless cookie 遺失 | `GROKBOY_BROWSER_HEADED=1` |
+| 列表空轉 | `report_blocked`；換篩選／關鍵字；勿重複同工具 ×3 |
+| 未確認就發 | **產品失敗**；AGENT_SYSTEM + `request_user_confirm` 擋 |
+| 登入牆 | 只 handoff auth，完成後 Enter |

+## 成功標準
+
+### 過
+
+- Phase A：登入（handoff）→ 找到 ~3 候選 + 1 則 Threads 草稿（含連結）→ `report_done`，**未發佈**
+- Phase B：本輪已核准同一草稿（聊天或 `request_user_confirm`）→ 登入 Threads（handoff）→ 發佈 → `report_done`（盡量含 URL）
+- 人工僅：蝦皮登入、Threads 登入、最終 confirm
+
+### 不過
+
+- 未確認就發 Threads  
+- 未 headed 導致重登／cookie 遺失  
+- 聯盟列表空轉  
+- 叫人手動貼全文（agent 應自己 type，只留 confirm）
+
+## 執行
+
+```bash
+export GROKBOY_API_KEY=你的金鑰
+export GROKBOY_BROWSER_HEADED=1
+cd ~/GrokBoy
+cargo run -p grokboy -- agent
+```
+
+貼上：
+
+1. [`prompts/examples/shopee-threads-phase-a.txt`](../../../prompts/examples/shopee-threads-phase-a.txt)  
+2. 審草稿後貼 [`prompts/examples/shopee-threads-phase-b.txt`](../../../prompts/examples/shopee-threads-phase-b.txt)，或回覆「核准，請發佈以下草稿：…」
+
+由 template 填出：`prompts/templates/phase-a.txt` / `phase-b.txt`。
