Report summary
4 stories cleared the bar, led by NYC's "Click to Cancel" rule is now in effect, Local Indexing to reduce tool calling and token usage, and Fingerprints are the new cookies.
Worth attention
NYC's Click to Cancel rule is now in effect, per the city's own page. It targets subscription cancellation flows, so any paid product with NYC customers (CalenCall, ContractorVerify) should confirm its cancel path is as easy as sign-up. Read the rule text before relying on this summary.
A builder write-up on local indexing to cut tool calls and token usage in agent workflows. It addresses a real cost lever for MCP and agent work, but the item carries no benchmarks, so check the post's numbers before adopting the approach.
Essay arguing browser fingerprinting is replacing cookies for tracking. Relevant if ContractorVerify or CalenCall rely on analytics or fraud signals, but the item has no data.
