What is Claude prompt caching and how do I use it?

Mark static prompt sections (system, tools) with `cache_control: {"type": "ephemeral"}`. Hits within TTL cost 10%—put static first.

How do you prune conversation history for Claude API cost savings?

Reverse-walk messages, estimate tokens (chars/4), keep last ~8k. Summarize olds into a state message.

No—up to 24h latency. Perfect for overnight gen, analysis; route realtime to live calls.
