Reuse stable AI context around attachment-heavy tasks
Repeatedly sending the same long background can add cost and delay. Cache static prompt content when an attachment signals the work is ready for that context.
Trigger
Attachment Added to Task
Triggers when an attachment is added to a task.
Action
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
Stable background material may need to be reused across calls, yet preparing it again adds friction.
- Reuse static prompt portions across calls
- Reduce repeated preparation of stable background context
- Use an attachment event as a cue for an established workflow
Setup
Build it in a few focused steps.
- 1Connect Asana and Anthropic administrator once in the Notis portal.
- 2Create an automation in Notis and give it a recognizable name.
- 3In one instruction, specify the static prompt content to cache and ask Notis to use Anthropic Prompt Caching for that reusable content.
- 4Choose Attachment Added to Task as the trigger.
- 5Choose where run reports should go, then test with one real attachment event.
Questions about this workflow
Does the attachment automatically become cached prompt content?
No. Identify the static prompt portions in your instruction. The event description only says an attachment was added to a task.
When is Prompt Caching appropriate?
Use it when you have static prompt portions you intend to reuse across calls.
