Bot version: Mastra + Gemini 3.0 Flash. Data source: Nelson’s 6-conversation archive (Google Drive, shared Mar 11). This bot has a richer goal structure than the historical version — 5 goals per conversation including a “supplier capabilities assessment” goal.

Bot contacts a shoe supplier about S-8002 black futsal shoes. SR requires logo customization (tongue + heel).
| Dim | Score | Notes |
|---|---|---|
| E1 Goal Completion | Partial | 6/8 goals achieved. Price ¥89/pair, MOQ 50–1000, lead time 15–20 days, dimensions & weight collected. ❌ Capabilities assessment PENDING. ❌ Custom logo pricing unconfirmed (supplier kept asking for the file first). |
| E2 One-Question | Fail | 3+ violations. Bundled file-sharing with price questions, asked 2 questions after statements. |
| E3 Turn Efficiency | Fail | ~18 bot messages. Repeatedly asked for logo pricing when supplier said “send me the file first” 3 times. Major loop. |
| E4 No Hallucination | Pass | No fabricated data about pricing or specs. |
| E5 Extractability | Partial | Good base data (price, MOQ, lead time, dimensions, weight, carton). Customization pricing unresolved. |
| E6 Auto-Response | Pass | N/A — no auto-responses in this conversation. |
| E7 Naturalness | Partial | Polite, natural Chinese. But repeated failure to understand “send me the file first” is unnatural. |
| E8 Rejection Recovery | Partial | Handled heel-logo pushback (“鞋跟那个位置不太好弄”) by offering to send file. But the repeated price loop is a failure to read the room. |
| E9 Customization | Partial | Asked about placement, format, pricing. Good start. Couldn’t complete — didn’t send logo file despite saying it would. |
S1 Negotiation: No attempt.
Bot contacts a curtain factory. SR requires logo customization. Conversation spans two days.
| Dim | Score | Notes |
|---|---|---|
| E1 Goal Completion | Partial | 6/7 goals. Price $6/piece (200 pcs), MOQ 200, lead time 10–12 days, weight ~1kg, packing specs, logo confirmed 10×3cm. ❌ Capabilities PENDING (supplier frustrated: “你到底要什么”). |
| E2 One-Question | Partial | 2 violations: long statement + tangent question, and multi-part capability question. |
| E3 Turn Efficiency | Fail | ~20 bot messages. Stalled overnight for logo file. Capability tangent frustrated supplier. |
| E4 No Hallucination | Pass | No fabricated data. |
| E5 Extractability | Partial | Core data good. Logo pricing not separately broken out — is $6 with or without logo? Unclear. |
| E6 Auto-Response | Pass | Supplier sent auto-greeting + FAQ card. Bot ignored and waited for real response. Correct. |
| E7 Naturalness | Partial | Handled “are you a bot?” well. But supplier got annoyed at capability questions (“你到底要什么”). |
| E8 Rejection Recovery | Pass | Supplier pushed to switch to voice call twice. Bot firmly but politely declined, citing platform policy. Good recovery. |
| E9 Customization | Partial | Logo confirmed, size adjusted based on supplier feedback (10×10 → 10×3). Good adaptation. Logo pricing not isolated. |
S1 Negotiation: No attempt.
Bot contacts a shoe supplier about skateboard sneakers. SR requires logo customization.
| Dim | Score | Notes |
|---|---|---|
| E1 Goal Completion | Partial | 4/7 goals. Price ¥75 (300), ¥67 (500), ¥62 (1000). MOQ 100–500. Lead time 20–45 days. ❌ Packing specs PENDING. ❌ Capabilities PENDING. |
| E2 One-Question | Partial | 2 borderline violations: rapid-fire messages and answer + question combos. |
| E3 Turn Efficiency | Fail | ~16 bot messages. Pursued carton specs when supplier said “I can’t answer without the order.” Confusing mid-conversation product link switch. |
| E4 No Hallucination | Pass | No fabricated data. |
| E5 Extractability | Fail | Price tiers and lead time good. No exact weight, no carton specs. Conversation scattered across topics. |
| E6 Auto-Response | Pass | N/A — no auto-responses. |
| E7 Naturalness | Partial | Adapted to supplier switching to English. But second product link mid-conversation was confusing. Robotic packing-specs pursuit. |
| E8 Rejection Recovery | Partial | Supplier said can’t provide carton specs without order. Bot kept asking variations instead of moving on. |
| E9 Customization | Partial | Got logo pricing tiers and lead time. Didn’t complete full branch (no file format, no placement confirmation). |
S1 Negotiation: No attempt.
Bot contacts a phone mount supplier. Quick, efficient conversation with a very responsive (possibly AI-assisted) supplier.
| Dim | Score | Notes |
|---|---|---|
| E1 Goal Completion | Pass | All goals achieved. Price $6.30/piece (200 pcs, with or without logo). MOQ 200. Lead time 7–10 days. Dimensions, weight, packing, logo pricing — all confirmed. |
| E2 One-Question | Partial | 1 violation: asked about two lead-time variants in one question. |
| E3 Turn Efficiency | Pass | 9 bot messages. Clean, efficient. All data in 9 turns with no waste. |
| E4 No Hallucination | Pass | Final summary accurately recaps all data. |
| E5 Extractability | Pass | Self-summary: “200个手机支架单价6.30美元，常规版交期7天，带Logo版10天，外箱尺寸60×36×45cm，重22.6kg.” Perfect. |
| E6 Auto-Response | Pass | Supplier responses looked AI-assisted. Bot treated them as real answers — correct, since data was accurate. |
| E7 Naturalness | Pass | Clean, professional, efficient. Good closing summary. |
| E8 Rejection Recovery | Pass | N/A — no rejections. |
| E9 Customization | Partial | Got logo pricing and lead time. Didn’t follow up on supplier’s mention of “定制包装MOQ500件”. |
S1 Negotiation: No attempt.
Bot contacts another phone mount supplier. Same product category as 2053. Conversation includes a full capabilities assessment.
| Dim | Score | Notes |
|---|---|---|
| E1 Goal Completion | Pass | All goals achieved. Price ¥7.5/piece (200 pcs). MOQ 1–1000. Lead time 1 week. Dimensions, weight, packing, capabilities — all confirmed. |
| E2 One-Question | Pass | Every bot message asks exactly one question. Excellent discipline. |
| E3 Turn Efficiency | Pass | 10 bot messages. Efficient, especially given the capabilities assessment adds extra questions. |
| E4 No Hallucination | Pass | No fabrication. |
| E5 Extractability | Pass | Supplier sent complete spec sheet. Bot acknowledged and moved to capabilities. Clean data. |
| E6 Auto-Response | Pass | Supplier sent auto-greeting with FAQ buttons. Bot ignored buttons and waited for real price. Correct. |
| E7 Naturalness | Partial | Efficient but capabilities questions feel formulaic in sequence: factory products → OEM/ODM → certifications → general MOQ. |
| E8 Rejection Recovery | Partial | Accepted “不” (no OEM/ODM) and “没” (no certs) correctly. But a human would probe: “if not full ODM, can you at least change colors?” |
| E9 Customization | Partial | Got logo MOQ (1000) and lead time. Didn’t probe logo pricing separately — is ¥7.5 with or without logo? |
S1 Negotiation: No attempt.
Bot contacts a storage box supplier. Conversation involves logo customization and a capabilities assessment.
| Dim | Score | Notes |
|---|---|---|
| E1 Goal Completion | Pass | All goals achieved. Price ¥5.2 (1000 pcs w/ logo), ¥9.5 (200 pcs). MOQ 200–1000. Lead time ~1 month (custom). Dimensions, weight, packing, capabilities confirmed. |
| E2 One-Question | Partial | 2 violations: multi-part capability question and multi-part packing question. |
| E3 Turn Efficiency | Fail | ~16 bot messages. Slow supplier needed follow-up. Bot asked about weight when supplier said “it’s on the listing page.” |
| E4 No Hallucination | Pass | No fabrication. |
| E5 Extractability | Partial | Two price tiers collected. Carton specs received as image (harder to extract). Weight incomplete. |
| E6 Auto-Response | Pass | Supplier sent auto-greeting (“客服离线中”). Bot waited for real response. Correct. |
| E7 Naturalness | Partial | Asked about weight when supplier said it’s on the listing. Asked “35×20×15 is in cm?” — slightly naive. |
| E8 Rejection Recovery | Pass | N/A — no rejections. |
| E9 Customization | Partial | Got logo pricing at scale. Discovered material customization possible. Didn’t pursue logo pricing at 200-piece level. |
S1 Negotiation: No attempt.

The latest bot is a modest improvement over the historical version (+3pp, 69% → 72%). The gains are in goal completion and hallucination avoidance. The persistent weaknesses are turn efficiency, one-question discipline, and customization handling — the same areas where our bot (Eric’s version) can differentiate.
The 72% baseline is what we need to beat on Friday.
