Prompt caching strategy for the Anthropic Messages API.
Anthropic’s prompt caching allows reuse of previously processed prompt
prefixes, reducing latency and cost. This module provides a configurable
strategy that annotates request components with cache_control markers.
Cache breakpoints are placed on:
- The last system prompt block (stable across turns)
- The last tool definition (stable across turns)
- Recent conversation turns (sliding window)
