Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install llm-semantic-cache-with-langcache

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent adds a cache-aside layer around your model calls with LangCache on Redis Cloud, tunes the similarity threshold between precision and hit rate, and splits caches by task type or custom attribute. You cut the cost and latency of repeated calls. LangCache is in preview.
