Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install openapi-specification-writing

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 writes an OpenAPI 3.0 or 3.1 specification: schemas, parameters, responses, examples and polymorphic schemas with discriminators. It serves as both documentation and contract. You get a specification file to validate and publish.
