Show HN: Cost.dev (YC W21) – making agents cost-aware and cheaper to call

Infracost launched Cost.dev, a local CLI for cloud-cost estimates in coding-agent workflows, and says it cut Claude output-token use by up to 79% and API cost by up to 67% versus a bare-Claude baseline.

Why it matters: HKR-H/K/R all pass: the local CLI cost-estimation mechanism and 79%/67% reduction claims are concrete. It is still a small vendor launch, so it sits at the featured floor, not same-day news.
