Redis LangCache Semantic Caching

This skill integrates Redis LangCache, a fully-managed semantic caching service, into OpenClaw workflows. LangCache stores LLM prompts and responses, returning cached results for semantically similar queries to reduce costs and latency.

Prerequisites

Before using LangCache, ensure the following environment variables are configured:

LANGCACHE_HOST=<your-langcache-host>
LANGCACHE_CACHE_ID=<your-cache-id>
LANGCACHE_API_KEY=<your-api-key>

Store these in ~/.openclaw/secrets.env or configure them in the OpenClaw settings.
