Engineering Playbook
Make the stable prefix boringly consistent
1
Order stable → dynamic
System prompt, tools, policies, long docs first; user-specific data last.
2
Canonicalize serialization
Freeze ordering, whitespace, JSON shape, and document delimiters.
3
Version prompt templates
Roll out intentionally and observe the temporary cold-cache impact.
4
Batch similar workloads
Temporal locality improves the chance entries remain warm.
5
Protect isolation boundaries
Treat provider cache scope and data handling as security architecture.
6
Test with real traces
Replay production-like prompts and compare cold versus warm behavior.
