All Implemented Interfaces:

Serializable, Comparable<AnthropicCacheStrategy>, Constable

public enum AnthropicCacheStrategy
extends Enum<AnthropicCacheStrategy>

Enum Constant Details

NONE

public static final AnthropicCacheStrategy NONE

No caching (default behavior). All content is processed fresh on each request.

TOOLS_ONLY

public static final AnthropicCacheStrategy TOOLS_ONLY

Cache tool definitions only. Places a cache breakpoint on the last tool, while system messages and conversation history remain uncached.

SYSTEM_ONLY

public static final AnthropicCacheStrategy SYSTEM_ONLY

Cache system instructions only. Places a cache breakpoint on the system message content. Tools are cached implicitly via Anthropic's automatic lookback mechanism.

SYSTEM_AND_TOOLS

public static final AnthropicCacheStrategy SYSTEM_AND_TOOLS

Cache system instructions and tool definitions. Places cache breakpoints on the last tool (breakpoint 1) and system message content (breakpoint 2).

CONVERSATION_HISTORY

public static final AnthropicCacheStrategy CONVERSATION_HISTORY

Cache the entire conversation history up to (but not including) the current user question. Places a cache breakpoint on the last user message in the conversation history, enabling incremental caching as the conversation grows.

Method Details
