Mobile marketplace harvest (MobileCLI)

Prefer this path for Taobao, Shopee, and Pinduoduo when the user has a trusted phone. Desktop web is the fallback (CAPTCHA / masked prices / risk control). AliExpress / Amazon: browser unless the user asks for the app.

Goal: give a reasonable model enough key steps to execute a deep sales-sorted harvest and SKU-accurate shortlist — not pixel click-paths.

Stack

• CLI on the user’s Mac: npx --yes [email protected] (pin a known-good version; prefer this over a broken local binary if Auto-review blocks installs)
• Device: real iPhone (or Android) with developer trust already set up
• iOS: MobileCLI Device Kit agent (not ADB); on Android, use the device bridge supported by the available mobile tooling
• Drive from the Mac that has the phone trusted (USB once, then network OK)

Prerequisites (do once per session)

1. npx --yes [email protected] devices — target device online
2. Phone unlocked (deep links and app launch fail on lock screen)
3. Auto-Lock → Never (Settings → Display & Brightness). Automation taps do not keep the screen awake
4. Note the device UDID; pass --device "$DEV" on every command
5. Confirm control works: apps foreground or a screenshot succeeds. If RPC/WDA times out, restart Device Kit / re-open the MobileCLI agent on-device, then retry — don’t thrash Shopee/Taobao taps while the bridge is dead

Command primitives

DEV=<udid>
MC='npx --yes [email protected]'

$MC apps foreground --device "$DEV"
$MC apps launch --device "$DEV" <bundleId>
$MC apps terminate --device "$DEV" <bundleId>   # after a crash / wedged UI
$MC dump ui --device "$DEV"                      # structured tree with refs
$MC screenshot --device "$DEV" -o /tmp/shot.png
$MC io tap --device "$DEV" '@e12'                 # ref from latest dump ui
$MC io tap --device "$DEV" 120,400                # x,y fallback
$MC io swipe --device "$DEV" x1,y1,x2,y2          # scroll: swipe up = y high→low
$MC url --device "$DEV" '<deeplink>'

Interaction rules

• Prefer dump ui + @ref taps over blind coordinates
• Avoid Dynamic Island / status bar (roughly y ≲ 80–90)
• After each navigation: dump or screenshot before the next decision
• One phone owner at a time — don’t run two harvests against the same device in parallel

Example bundle IDs

Generic deep-harvest loop (all apps)

Use this loop for every platform. Depth bar matches the parent skill: exhaustive by default (≈10–20 genuine candidates, not the first 3).

1. Launch the marketplace app (or deep-link into search if available)
2. Run several queries using the product name, brand, category terms, and relevant variant attributes
3. Sort by sales (销量 / Top Sales / orders) — never trust default 综合 / Best Match alone
4. SERP pass: scroll multiple screens; capture title, headline price, sold/rating, and variant hints into a jsonl. Filter out accessories, incomplete bundles, and bait variants that do not match the request
5. PDP pass: open 12–20 unique high-signal listings (volume + protocol fit). On each:
   • Open the SKU / options sheet
   • Select the exact variant the user needs (such as size, colour, capacity, region, plug, or protocol)
   • Re-read after-selection price + shipping / GST / 集运 / ETA
   • Note any title-to-SKU mismatch where the selected option changes a material requirement or capability
   • Close the sheet / back out — do not add to cart until the user confirms the shortlist pick
6. Persist *-harvest.jsonl + *-final.md (+ screenshots). Merge platforms in the parent skill’s comparison table
7. Hard stops: lock screen, login/CAPTCHA, payment — hand to user. Never enter passcodes/secrets. Never place order

Headline SERP prices often belong to the cheapest accessory, smallest size, or incomplete bundle — compare on opened variant prices.

Platform key steps

Pinduoduo (拼多多)

1. Prefer deep link search (phone unlocked):
   pinduoduo://com.xunmeng.pinduoduo/search_result.html?search_key=<url-encoded>
2. Tap 销量 to sort
3. Use category-specific filters when present to remove irrelevant variants
4. Scroll deep; dump UI — prices often show as 约S$ + amount on SG accounts
5. Open PDPs; select the exact requested SKU and record goods + GST/shipping (SG包邮 / 海运 / 集运仓 are common)
6. Explicitly confirm any capability-changing SKU attribute before recommending

Shopee SG

1. apps launch → com.beeasy.shopee.sg
2. Search queries in English/Chinese as needed; sort Top Sales / highest sold
3. Deep SERP scroll; keep Mall / Preferred / local SG vs CN as trust + shipping signals
4. Open PDPs; select the requested variant via the options / Buy sheet, read all-in SGD + ETA, then close (no cart)
5. If the app crashes: apps terminate → relaunch → resume from last jsonl (don’t restart SERP from zero unless needed)
6. If MobileCLI RPC times out during a crash spiral: fix Device Kit / WDA first, then reopen Shopee

Taobao (淘宝)

1. Launch 淘宝; search Chinese keywords; sort 销量
2. Deep scroll across multiple queries using the product and its important variant attributes
3. Open item pages; select the exact requested SKU, prefer the after-coupon price, and note any required accessories or compatibility constraints
4. Record shipping reality: China domestic vs 直邮新加坡 vs 集运 — all-in must include forwarder/GST when relevant
5. For visual/custom goods, still apply parent skill 图集 / 图文详情 evidence rules when those surfaces exist in-app

Crash & bridge recovery

Artifacts & merge

Per platform, write under a known folder (e.g. Desktop or task workspace):

• <platform>-<product>-harvest.jsonl — one object per candidate (title, price, sold, rating, SKU, shipping, screenshot path, source query)
• <platform>-<product>-final.md — sales-aware table of keepers
• Screenshots for disputed SKUs / shipping

Then merge with other platforms using the parent skill shortlist format (all-in local currency, rating, sold, trust, shipping, variant stock) and recommend before cart.

Cart stop

Identical to parent skill: shortlist → user yes → add exact variant to cart → user pays. Mobile does not change that boundary.
