Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install mwaa-workflow-failure-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 environment (provisioned or Serverless), pulls the errors and CloudWatch logs, classifies the failure and looks for the context that caused it. You get the likely cause, its impact and the fix to apply.
