Prompt Caching
Tool to cache and reuse prompt content to reduce costs and latency. use after you have static prompt portions you intend to reuse across calls.
Why this helps
Repeatedly sending the same long instructions for event summaries can add avoidable latency and cost.
- Reuse static prompt portions across summary calls.
- Keep changing event details distinct from reusable instructions.
- Reduce repeated prompt cost and latency where caching applies.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Anthropic administrator once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3In one instruction, describe the static summary guidance to cache and how current event details should be used.
- 4Pick Calendar Event Sync as the trigger and choose a report channel.
- 5Test with one real synced event and check that the cached content is static guidance.
Questions about this workflow
What should be cached?
Use prompt content that stays the same across calls, such as stable summary instructions or reference text.
Should changing event data go into the static portion?
No. Keep event specific details current for each run and cache only content intended for reuse.
