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 browseCLI 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.pyservices/momo_crawler.pyservices/marketplace_product_matcher.pycompetitor_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

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

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

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 APIbrowse 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。
  • Matcherbrowse 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 manifestURL、platform、crawler、parse failure、viewport、tile coordinates、artifact path、evidence intent。
  3. Phase 2 用 manifest 收集 replay samples對照 marketplace_product_matchercompetitor_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 metadataFAISS 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 既有 structured crawler 失敗時自動產生 visual manifest queue 正式價格仍以既有 parser/API/matcher 為準
P1 Shopee Taiwan / Coupang Taiwan 抓公共搜尋頁商品卡、促銷 badge、店家/配送/評分視覺證據 不登入、不碰購物車、不繞過 anti-bot
P2 Yahoo 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

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 secretcapture worker 後續消費 manifest 產生 screenshot/tile receipt。

Application portfolio

python scripts/ops/report_pixelrag_application_portfolio.py
python scripts/ops/report_pixelrag_application_portfolio.py --area commerce
python scripts/ops/report_pixelrag_application_portfolio.py --area rag --include-forbidden

此 portfolio 把 PixelRAG 可整合範圍正式分成 commerce、RAG、UX、ops、marketing、governance lanes。每個 lane 都必須有 priority、status、可整合對象、use cases、next machine action 與 no-write 邊界forbidden lane 明確拒絕 login-only、cart、checkout、private coupon、session 與 anti-bot bypass。

安全邊界:

  • read-only不登入、不下單、不加入購物車、不寫第三方狀態。
  • 不從像素結果直接寫正式價格或同款判斷,只寫 artifact / review diagnostics。
  • 不使用 GitHub runtime 依賴;不讀 secrets / sessions / cookies。
  • 不呼叫 hosted embedding / VLM API如需 embedding必須走 Ollama-first 並保留成本/品質 benchmark。
  • 若穩定 XHR/API 可取得同樣資訊,仍優先回補 structured parser不把視覺 fallback 變成主路徑。
