Prompt Caching Middleware.
Optimizes API usage by caching conversation prefixes for Anthropic models.
Requires both langchain and langchain-anthropic packages to be installed.
The middleware ta
Middleware that exposes Anthropic's native bash tool to models.
State-based text editor tool middleware.
Provides Anthropic's text_editor tool using LangGraph state for storage.
Files persist for the conversation thread.
Filesystem-based text editor tool middleware.
Provides Anthropic's text_editor tool using local filesystem for storage.
User handles persistence via volumes, git, or other mechanisms.
