SkillsTech Runtime is the shared AI layer behind every product - context, routing, evaluation, proof, safety, and cost control. Products speak tasks and privacy modes; Runtime owns models, prompts, cost, and proof.
One Context Pack standard and a router that picks the cheapest model clearing each task's bar - under a hard privacy gate.
Per-task eval gates make model swaps a config change. AI work emits verifiable proof events as a side effect.
Privacy modes enforced before egress, redaction before proof leaves the device, and cost tracked per task - never billed here.
