We Searched eBay for 237 Recalled Products. Only 45 of 12,562 Listings Named the Model.

Two developers built RecallDesk, a weekly recall-monitoring tool for resale shops that cross-checks CPSC recall notices against a store's inventory and eBay listings. In a study of 151 CPSC recalls from July to October, they found 73 notices list the model or SKU number only in the description, and of 12,562 unique eBay listings matching 237 recalls, just 45 titles contained a recalled identifier. The team said keyword filters can flag those 45 but cannot clear the remaining listings, since a missing model number proves nothing.

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 2: Side Hustle https://dev.to/challenges/hacktoberfest-week2-2026-10-12 Built by @dronzer2code https://dev.to/dronzer2code and @soumyadeepdey https://dev.to/soumyadeepdey . Picture a Thursday afternoon at a kids' consignment shop a composite, not a real store . A parent drops a bag at the intake desk: a toy fire truck, a wooden learning tower, a sleep machine, some toddler pyjamas. The staffer has about two minutes per item. That morning the U.S. Consumer Product Safety Commission posted its weekly batch of a dozen or so recalls. Nobody at the desk has read them. Here's the part of one notice that matters, from September 17, for the Melissa & Doug Lights and Sound Fire Truck about 84,000 sold at Target : Affected units will have one arrow pointing to the number 25 and the second arrow pointing to the number 4 or 5 or they will have one arrow pointing to the number 26 and the second arrow pointing to the number 3. The arrows are two date dials under the battery box. The brand and the price tag can't answer it. You have to turn the toy over. For the shop this is a legal question. CPSC's Resale Round-up https://www.cpsc.gov/Newsroom/News-Releases/2009/CPSC-Launches-Resale-Round-up-Campaign-to-Keep-Dangerous-Recalled-Products-Out-of-Resale-Stores-and-Off-the-Internet campaign told thrift stores and online resellers directly that re-selling recalled products violates federal law. On October 6, Consumer Reports, via News4Jax https://www.news4jax.com/money/2026/10/06/consumer-reports-warns-parents-about-unsafe-baby-gear-being-sold-on-craigslist-ebay-facebook-marketplace-other-sites/ , warned that banned and recalled baby gear is still listed on Craigslist, eBay and Facebook Marketplace. eBay said its product-safety systems AI models, keyword rules and manual review stopped 21 million potentially unsafe listings worldwide in 2025. And a 2026 Buchalter analysis https://www.buchalter.com/blogs/cpsc-escalates-enforcement-in-2026-expanded-market-oversight-civil-penalties-and-criminal-exposure/ notes that CPSC has now sent its 100,000th takedown notice for recalled or banned products sold online. We built RecallDesk for that desk. Every Thursday it reads the new recalls, checks a shop's stock and eBay store against them, and prints one page: what to pull, and what to flip over. Before any model code, we pulled every recall CPSC posted from July 18 to October 15: 151, all on Thursdays, 48 for children's products. Adding children's recalls back to 2023 shops sell old baby gear too made 591. Then, with plain code and no model, we asked where the identifying number appears. In 73 of the 151 notices, the model, item, style or SKU number is only in the description, never in the headline or product name 24 of 48 for children's . "Woodure Toddler Kitchen Step Stools Recalled" gives you the brand. Whether your stool is affected is further down: "The model number is engraved on the underside of the bottom step." On the resale side, SerpApi's eBay engine searched for 237 recalls the 151 recent ones plus 86 older children's ones; 235 paid searches, since two recalls shared a cached query : 14,068 results, 12,562 unique listings . We counted titles containing a recalled identifier, ignoring case and dashes. There were 45 , across 13 recalls. For children's recalls, 2 of 6,901 , both for one brand of pool dive sticks. Second-hand sellers are the least likely to type one: 17.1% of all listings were pre-owned 20.2% for children's recalls , but only 9% of the 45 exact hits were. That count shaped the product. A keyword filter can flag the 45 but can't clear the other 12,517, because a title without a model number proves nothing. For most same-brand items the useful answer is "go look at the label", plus where the label is. RecallDesk is a weekly recall desk for resale businesses. A shop loads its stock once CSV or paste and, optionally, its eBay seller name. Every Thursday at 2:00 PM Eastern, after CPSC posts, it turns each new recall into a structured spec brand, model numbers, date codes, sold window , compares every item and live listing against the specs that could apply, applies the shop's past corrections, and prints one card: DO NOT SELL for match , CHECK LABEL for check with the place to look, and nothing for no match . A trimmed excerpt of a real card for the demo shop, from a run with the fine-tuned model on Tinker: === RECALL CARD card 2026-10-15 little-loop Little Loop Kids Consignment week of 2026-10-15 === 6 new recalls this week | 60 items checked | model: qwen3.5-4b-recalldesk-lora DO NOT SELL 8 x Papablic Convertible Bedside Sleeper with Play Yard model PAPA03001AI - CPSC 27027 why: Listing matches recalled brand, product type, and explicitly states the recalled model number. remedy: Stop use, destroy product, email photos for refund x Love To Dream Portable Sleep Machine with Night Light model LTD-SM23 - CPSC 26798 CHECK LABEL 7 ?

The Love To Dream recall covers model LTD-SM23 with date code 7W15TN, so our own rule 3 says the item should be CHECK LABEL, not DO NOT SELL. The shop would pull a sleep machine that might be fine. The dashboard is Next.js with BoardUI https://boardui.com components. Most owners only need the printable card. The rest is for setup and for answering "why was this flagged?" Any inventory row opens beside the recall it was compared with. "Not a match? Correct this" is how a shop teaches the system about its own stock. The recalls page puts CPSC's text, identifiers highlighted, next to the extracted spec: The eBay monitor is for flippers who sell online: Who would pay? Kids' consignment shops, which take in second-hand children's goods from strangers daily. Seasonal consignment events, with thousands of items and volunteer staff in one weekend. eBay and Poshmark flippers buying returns pallets blind.

Before you list it, check it. A weekly CPSC recall check for kids' consignment shops and eBay resellers. Reselling a recalled children's product is a federal violation in the US, and recalled baby gear keeps turning up on resale sites. CPSC posts about a dozen recalls every Thursday, and in 73 of the 151 recalls since 2026-07-18 the model number that decides it is only in the description's fine print . eBay sellers almost never type it into a title. RecallDesk reads every recall, checks a shop's inventory and eBay listings against it, and prints one card a week DO NOT SELL for items that are the recalled product, CHECK LABEL with exactly where the label is for items only a person holding it can decide. Then it goes quiet until next Thursday. The rule of the build: the big model teaches, the small model reads, code decides. … There are four directories. ml/ holds data collection, specs, eBay search, labelling, training and evaluation. agent/ holds the Temporal workflows, the API and shop memory. web/ is the dashboard. shared/schema.py is the single contract the other three code against. Every figure here traces to ml/results/ .json , data/ /…stats.json , docs/charts/chart data.json or a transcript under agent/demo logs/ . License: MIT. We wrote the decision rules before choosing a model. Our three verdicts are defined in ml/LABELING.md https://github.com/SoumyaEXE/recalldesk/blob/main/ml/LABELING.md : Seven ordered rules apply them. Rule 7 did the most work: an unbranded listing with no recalled identifier is a generic look-alike, so no match , unless it names something only the recalled product has, like a licensed character. The model outputs one small JSON object, and plain code maps it to the card. A large open model, Qwen3.5-397B-A17B , wrote specs for all 591 recalls 100 seconds, $2.21 , and code drops any identifier not actually in the notice. It also labelled 3,300 recall, listing pairs, and kept calling unbranded look-alikes "check": 1,134 checks on the first pass, 872 after we added rule 7 to the prompt. Still too many, so we stopped asking. A short function checks the rule and rewrites the training target when the teacher breaks it: php def is generic lookalike spec: dict, title: str - bool: words = set norm title .split if brand words spec.get "brand", "" & words: names the brand - not generic return False if id hit spec, title : shows a recalled identifier - not generic return False return len distinctive words spec & words < 2 fewer than 2 distinctive product-name words It fired on 391 pairs: 357 in training and 34 in the test split. Every change is logged in data/labeled/targets.jsonl . At $2.20 per 1,000 checks , the 397B is too expensive to run for every shop every week. So with Tinker we fine-tuned Qwen3.5-4B LoRA rank 32 on its corrected labels: 3,007 pairs, 2 epochs fixed in advance, 376 steps at batch 16, learning rate 4.91e-4 decaying linearly, loss on the JSON only. Our code assembles batches and calls forward backward and optim step ; Tinker's GPUs do the rest, and save weights for sampler returns the tinker:// path the weekly workflow samples. About 38 minutes; held-out loss 0.724 → 0.228. With a ~400-token prompt the teacher's is ~1,060 , the student costs $0.19 per 1,000 checks . Tinker spend at list prices: specs $2.21, discarded first labelling run $6.80, second run $7.47, training $2.39, evaluation $0.23, about $19.10 total. SerpApi: 235 of the free plan's 250 searches. We split by recall : 217 for training, 20 held out 12 children's , with no recall or listing shared. One try per pair at temperature 0; invalid JSON is wrong. The evaluation harness bootstrap CIs, exact McNemar and the Temporal crash-test pattern come from @soumyadeepdey https://dev.to/soumyadeepdey 's earlier open-source TrailTruth project repo https://github.com/SoumyaEXE/trailtruth . One caveat shapes everything below. We built a blind labelling tool but didn't finish human labels in time, so the answer key for the 293 test pairs is the teacher's verdict with rule 7 applied by code , not a person's. The scores show how faithfully a 4B learned the teacher's rulebook on unseen recalls, not how often it's right about the world. | On 293 held-out pairs | Accuracy 95% CI | False alarms of 255 | Risky pairs flagged of 38 | $ / 1k checks | |---|---|---|---|---| | Qwen3.5-4B, base | 0.512 0.457–0.570 | 120 | 34 | $0.22 | | Qwen3.5-4B, base + teacher's full rulebook | 0.625 0.570–0.679 | 106 | 36 | $0.37 | | Identifier/keyword rules, no model | 0.864 0.823–0.901 | 22 | 22 | $0 | | Teacher, Qwen3.5-397B-A17B | 0.884 0.846–0.918 | 34 | 38 | $2.20 | | Qwen3.5-4B + RecallDesk LoRA | 0.918 0.884–0.949 | 12 | 26 | $0.19 | The teacher's 38 of 38 is automatic, because every gold "check" is one of its own. Its 34 false alarms are exactly the pairs rule 7 overrode. The base 4B returned invalid JSON on 14 pairs, and every other model on none. Fine-tuning moved the 4B from 0.512 to 0.918 +40.6 points, 95% CI +33.8 to +47.1, exact McNemar p < 0.001 . Against the teacher the gap +3.4, p = 0.20 isn't significant: same reading, about a twelfth of the cost. For a shop the false-alarm column matters most. The base model sent 120 of 255 harmless listings to CHECK LABEL, which would bury the real ones. The LoRA sends 12. The price: the LoRA flags 26 of the 38 risky pairs ; its base flagged 34 on risky pairs alone the base is ahead, 11 to 3, p = 0.057, not significant . Nine of the twelve misses are one recall, a Sviyatp pool drain cover that, per CPSC, "has no labeling or product identification on the product itself". The listings are unbranded white drain covers, which rule 7 reads as no match, and that's what the student said. Our coded rule kept them as "check" only because the titles share "dual suction outlet" with the product name printed on Sviyatp's packaging. Two more misses are unbranded baby toys; one is a 14-pack of finger lights against a recall of 28- and 30-packs. So it's a genuine trade: fewer false alarms in exchange for trusting rule 7 on products with no label at all. On the 180 children's pairs the LoRA scores 0.933, the base 0.428. A concrete false alarm: for TheKiddoSpace's recalled LED hover ball, eBay returned "Rechargeable Hover Soccer Ball LED Lights Air Power Indoor Outdoor Toy Kids 3+", no brand anywhere. The base said check because the listing "matches the brand". The LoRA said no match : "Generic look-alike: no brand and no recalled identifier in the listing." Per-request latency on Tinker's hosted sampler is 2.3–2.8 s for every model, so the win is cost, not speed. Each call is engine=ebay , ebay domain=ebay.com , ipg=50 , with the teacher's first query as nkw . Responses are cached under a hash of their parameters, so nothing is paid for twice, and a 429 halts the run. A shop's own store uses sasl=<seller & saslop=1 the engine has no ssn . Seller names stay in the raw cache; published data uses a hash. recalldesk-weekly-sweep is a Temporal Schedule for Thursdays, 14:00 America/New York. It next fires October 22 and 29 at 18:00 UTC, then November 5 at 19:00 UTC once the clocks change. Every step is an activity with its own failure policy: CPSC fetches back off, then fall back to a committed snapshot; classification heartbeats with six calls in flight, so a stuck call gets retried; malformed JSON is retried, then answered by the rules with a note on the card; a SerpApi 429 is never retried, and the step records source=snapshot SerpApi quota/429, not retried . Does a dead worker lose work? We started a check of the demo shop's 60 items 176 comparisons and killed the worker process 12.4 seconds in, 19 items done. For three seconds nothing ran, while Temporal still showed the workflow running with six activities in flight. A fresh worker replayed the history and published the card at 33.2 seconds. The history: 60 item activities, each scheduled once; the 20 finished before the kill were kept, the 6 in flight got a second attempt, none completed twice. This rehearsal used the rules classifier plus 1.2 s of artificial latency per item, to make sure the kill hit mid-run. Then we did it again with the real LoRA on Tinker workflow check-little-loop-2026-10-17-1a16-crashdemo . We killed worker pid 12764 at 73.2 seconds with 18 of 60 items done and 6 calls in flight, and a fresh worker started at 76.5 seconds. The card was published at 170.9 seconds. Again there were 60 activities, each scheduled once: 18 kept, 6 retried, none completed twice, 344 history events. The chart below is this LoRA run; the Temporal UI screenshot after it is from the rehearsal. The dashboard's runs page badges the same run as resumed: With injected faults on the LoRA worker fake CPSC 503s, hung calls, broken JSON , ten items needed retries and three were answered by the labelled fallback, and the card noted it. A manual sweep for recalls since October 8 fetched 14 live from CPSC and fanned out to one child workflow per shop, producing two cards in 83 seconds. No model can know that this shop's fire truck reads 24/11 on its dials. The staffer holding it can. Their "Not a match? Correct this" note is stored as a memory in the shop's own Backboard assistant explicit memory endpoints only . Next run, load shop memories retrieves it by meaning, not exact text. The memory is kept away from the model, which still answers check ; code then changes the verdict to no match and lists the correction on the card. In the recorded run LoRA on Tinker, Backboard memory 063081d1-… , CHECK LABEL went from 7 items to 6 and DO NOT SELL stayed at 8. An override needs a matching recall number and at least 60% word overlap with the remembered item, so a note about one tower can't clear another. The same run also applied an older HARPPA tower correction memory beeeda90-… . One honest wrinkle: semantic search was flaky on long item names. The full "Melissa & Doug Lights & Sounds Fire Truck Activity Board" query didn't return its own correction, while a shorter brand + name query did. So each run now searches with brand, name and model only, and also lists the shop's memories once, putting both through the same overlap guard. In the recorded run the fire-truck correction came through the list. A small shop's margins can't carry a frontier-model bill per item per week. Open weights let us train a 4B for this one job, and training is where the false alarms went; a closed API would have left a choice between the expensive model and the noisy prompt. No lock-in either: the adapter exports as PEFT weights for a shop's own vLLM or llama.cpp server, selected with one environment variable, and with no keys RecallDesk still runs on its rules classifier and labels its cards accordingly. Specs, splits, predictions and the eval script are in the repo, so anyone can re-score our 293 pairs or add the human answer key we didn't get to. Privacy: everything RecallDesk reads is public CPSC's open API, public eBay search results via SerpApi . Seller usernames never leave the gitignored raw cache, and the demo shops are invented. By default, though, labelling, training and inference run on Tinker's hosted GPUs; local means the exported adapter. A coordinating session ran five parallel coding agents ML and data, Temporal backend, dashboard, charts and screenshots, writing . Its first output wasn't code but CONTRACT.md https://github.com/SoumyaEXE/recalldesk/blob/main/CONTRACT.md : every data shape, every API route, and the rule that code, not the model, decides what reaches the card. With that pinned, the dashboard was built on real-data fixtures while training was still running, and the parts fit on first connection. No paying shop has used RecallDesk yet, and we won't dress up a hypothetical as a customer. From the first kids' consignment owner we want to learn how long recall checks take today, whether CHECK LABEL is clear without a walkthrough, what price they'd name before seeing ours, and what would stop them. We suspect liability and data entry, which would put a POS import ahead of any model work. So here's the offer, open until winners are announced: if you run a resale shop or flip on eBay in the U.S., send us your item list or seller name and we'll run it through RecallDesk this Thursday and send you the card, free. We'll add the first real reply to this section, with permission. sasl + saslop=1 , with 429s never retried. If you run a kids' consignment shop or a seasonal sale, or you flip returns on eBay, comment or message us. We'll run your store through RecallDesk free this Thursday and send you the card. For everyone else: has a recall ever made you turn something over to read the label, and what was it?
