Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install openapi-spec-generation-3

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 asks the useful questions (version, format, endpoints), then builds the spec: schemas, pagination, errors, parameters, response codes and security. It ends with a quality checklist so the file passes a linter.
