# Browse.sh Crawler Playbook > Scope: MOMO / PChome 動態頁診斷、selector 探勘、XHR/network trace。正式價格資料仍以既有 Python crawler、PChome API 與資料庫閉環為準。 ## 評估結論 - `browse.sh` 是 Browserbase 提供的 browser CLI,主打 open web catalog、browser primitives、debugging、cloud sessions 與 network/console tail。 - 官方安裝入口為 `npm install -g browse`,CLI 名稱是 `browse`。 - 對本專案最有價值的地方不是取代爬蟲,而是當 MOMO/PChome HTML 或前端 XHR 改版時,快速看 selector、console、network 與可重放 skill。 - 本機目前 Node 16 因 `icu4c` 動態庫缺失無法啟動,不能在本機直接安裝或執行 `browse`。導入方式先採 optional wrapper,不影響 production scheduler。 ## 使用邊界 - 只允許做 read-only 診斷,不登入、不下單、不加入購物車、不寫第三方狀態。 - 不把 `browse` 放進排程主路徑;若未來要排程化,需另開 ADR 與 feature flag。 - 不把 `browse` 輸出直接寫成正式價格;所有正式比價仍需經 `services/pchome_crawler.py`、`services/momo_crawler.py`、`services/marketplace_product_matcher.py` 與 `competitor_match_attempts` 診斷。 - Cloud sessions 可能需要 Browserbase 帳號與憑證;憑證不可寫入 repo。 ## 本地檢查 ```bash python scripts/tools/browse_sh_probe.py ``` 可用時會輸出 `available=true` 與版本;不可用時會輸出原因。若 `browse` 不在 PATH,可用: ```bash BROWSE_SH_CLI=/path/to/browse python scripts/tools/browse_sh_probe.py ``` ## 診斷流程 1. 先用既有 crawler/API 重現問題,保存失敗 SKU、搜尋詞、候選網址與 matcher diagnostics。 2. 使用 `browse` 開同一頁,查看搜尋結果 DOM、network 與 console。 3. 若找到穩定 XHR/API,優先回補到 Python crawler;若只能走 DOM,才更新 selector。 4. 新增或更新單元測試,至少覆蓋搜尋詞、候選解析與 matcher hard veto。 5. 只在測試通過後部署 app/scheduler/bot;不得重建或重啟 `momo-db`。 ## 常用命令 ```bash python scripts/tools/browse_sh_probe.py -- --version python scripts/tools/browse_sh_probe.py -- skills list python scripts/tools/browse_sh_probe.py -- open "https://24h.pchome.com.tw/" python scripts/tools/browse_sh_probe.py -- network --tail python scripts/tools/browse_sh_probe.py -- screenshot ``` ## MOMO/PChome 導入策略 - PChome:目前已有搜尋 API 與商品 API,`browse` 只用於確認 API 參數、分頁行為、前端是否切新 endpoint。 - MOMO:若既有 BeautifulSoup selector 失效,先用 `browse` 找出前端實際 XHR;找到 API 時優先改成 structured API parser。 - Matcher:`browse` 只提供候選證據;是否為同款仍由 `marketplace_product_matcher.score_marketplace_match()` 決定。 ## PixelRAG-style 視覺證據 fallback 2026-07-09 評估 PixelRAG 後,結論是「可導入,而且不應只限 MOMO/PChome」。PixelRAG 的核心價值是把渲染後頁面截圖切成 tiles,讓 AI 讀到 HTML parser 可能丟失的視覺結構;本專案第一階段採用這個視覺證據思路,擴充成多電商 public marketplace visual evidence layer,不直接拉外部 runtime、不用外部 embedding API、不把像素結果寫入正式價格表。 導入順序: 1. 既有 PChome API / MOMO structured parser 先跑;若 parser 結果為空、價格欄位缺失、規格/組合資訊疑似只存在渲染畫面,才啟動視覺證據 fallback。 2. Phase 1 只輸出 screenshot/tile manifest:URL、platform、crawler、parse failure、viewport、tile coordinates、artifact path、evidence intent。 3. Phase 2 用 manifest 收集 replay samples,對照 `marketplace_product_matcher` 與 `competitor_match_attempts` 的診斷結果,評估是否提高身份證據覆蓋率。 4. Phase 3 才評估 Ollama-first multimodal embedding;未完成 GCP-A → GCP-B → 111 視覺 embedding 驗證前,不做自動像素檢索。 5. Phase 4 若需要索引,優先設計 pgvector-compatible evidence metadata;FAISS 只能先當本地研究/ADR 候選,不直接進 production。 6. Phase 5 才談 crawler fusion;正式 `competitor_prices` / `competitor_price_history` 寫入仍需 matcher replay/canary 證據。 多電商優先順序: | Priority | Platform | PixelRAG 用途 | 邊界 | |---|---|---|---| | P0 | MOMO / PChome

Shopping / ETMall | 補促銷券、快速到貨、活動價格等視覺訊號 | 先做 controlled probe,再決定 parser | | P3 | friDay / Rakuten Taiwan | 先建立 probe profile 與 search manifest | URL pattern 需 runtime receipt 驗證後再排程 | 已支援的 platform code: ```text momo pchome shopee_tw coupang_tw yahoo_shopping_tw etmall_tw friday_tw rakuten_tw ``` 自動觸發: - `PChomeCrawler.fetch_region_page` 找不到商品 ID 時會 queue PixelRAG manifest。 - `PChomeCrawler.fetch_product_details` API 回傳但無可解析商品時會 queue 商品頁 manifest。 - `PChomeCrawler.search_products` 搜尋無商品 ID 或 request error 時會 queue 公開搜尋頁 manifest。 - queue 預設路徑:正式 app 容器 `/app/data/ai_automation/pixelrag_manifest_queue`,本機為 `runtime_artifacts/pixelrag_manifest_queue`。 - queue 只寫 artifact,不寫 DB、不寫正式價格、不讀 secret;capture worker 後續消費 manifest 產生 screenshot/tile receipt。
