Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install langchain-middleware-ordering

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 assembles the redaction, guardrail, token budget, caching and retry middlewares in the recommended order, so personal data never enters a cache key. You get a composed and documented chain.
