Pay Double On Purpose: Prompt Cache TTL | 26 Aug 26
Claude Code ships promptCacheTtl and subagentPromptCacheTtl so long sessions can hold a one-hour prompt cache while short-lived subagents stay at five minutes — and we explain what a prompt cache actually is, why a cache write costs more than a normal request, and when the bigger bet pays off. Plus Claude Code and Antigravity CLI independently narrow over-broad permission wildcards on the same day, Gemini CLI ships a release where most merged PRs were written by an agent working the backlog, and Antigravity adds voice dictation over SSH plus a fix for silent file corruption on non-ASCII code. Hosts: Alex & Jules. New episodes daily.
