Beneath the 100x Myth: Agent Engineering Architecture from CLI to Multi-Harness

OpenAI's VP says we can now "easily get 1000x engineers," but METR's randomized controlled experiment found AI made senior developers 19% slower. Between these two numbers lies an entire terminology framework that hasn't been clearly explained: GUI/CLI/TUI/AUI are interfaces, API/SDK/MCP are integration protocols, Harness is the execution system, and Multi-Agent/Multi-Harness/Multi-Vendor are three distinct dimensions. This article dissects all six concept pairs layer by layer, backed by official documentation and verifiable experiments, and ends on a SWE-bench leaderboard.

An 89-Yuan Chicken Drumstick Bucket Sold for 31: Exposing the 'Coupon Arbitrage' Industry Nurtured by Food Delivery Subsidy Wars

Taobao Flash Deals' 50 billion yuan in subsidies, Meituan's voucher discounts, and Tustin's 11-yuan promotional bundles created enough price arbitrage to spawn a resale chain where people hoard vouchers on your behalf with just a phone number. This article verified the cost structure of the 31-yuan drumstick bucket — the widely circulated 22.8 yuan cost figure is wrong; the real gross margin is only about 1–4 yuan — and breaks down the legal boundary: pure resale is gray-area and non-criminal, but exploiting platform loopholes crosses into fraud.
