Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install application-threat-model

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 builds or updates a threat model based on the actual architecture: actors, trust boundaries and security-relevant failure modes. The result can be saved to a given path and reused by the other analysis steps.
