Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install cloud-firewall-acl-diagnosis

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 identifies the firewall type (Internet, NAT or VPC), queries traffic logs and matching rules, then explains why a rule does not apply. It never creates, changes or deletes anything and only gives console guidance. WAF issues belong to another skill.
