Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install idempotent-api-operations

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 an idempotency key to requests, stores the response, protects the database with a unique constraint and schedules cleanup of expired keys. You get operations that can be retried without duplicate effects.
