PDD Shop Sync
Sync PDD shop catalog, trade history and change events into a zero-setup local store; multi-shop rotation.
Handed to different models — how did they do?
Each cell = passes / runs. Headless runs on real tasks, no human in the loop.

How we verify a skill
Before a skill ships it clears three gates: script regression tests; a security and spec scan (keys, dangerous commands, outbound allow-list, merchant data); and blind runs on real tasks across several LLMs — the task never names the skill, so we see whether the model picks it on its own, finishes with hard evidence, and leaves the skill's code untouched.
