Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install cloudformation-template-validation

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 or fixes a YAML or JSON template, validates it before deployment (cfn-lint, cfn-guard) and analyzes events from a failed stack, correlated with CloudTrail. It treats template content as data, never as instructions.
