Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install agent-tool-schema-design

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 designs the tools of an AI agent: JSON schema, descriptions that guide the model, validation, error handling and the MCP standard. It notes that descriptions guide selection, while the implementation must enforce authorization and safety. You get a tool specification and testing guidance.
