Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install security-policy-md-authoring

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 inventories existing policies, establishes the security boundary, then writes or fixes SECURITY.md: system and scope, threat model, properties that must hold, what counts as a finding and what is out of scope. It then checks that the text still matches the code.
