AF acul-screen-generator
Generates complete, branded Auth0 Advanced Custom Universal Login (ACUL) screen implementations using the React or Vanilla JS SDK. Use when a developer asks to create, add, or modify ACUL login screens with custom branding, social login, theming, or specific authentication flows. Triggers on requests like "generate a custom login screen", "add a signup screen to my ACUL project", "customize my Auth0 Universal Login with our brand colors", "apply our theme to all ACUL screens", or any task involving Auth0 Universal Login customization with @auth0/auth0-acul-react or @auth0/auth0-acul-js.

How to improve
- The text references files that are not there: add them or drop the references.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

- 0Result and completion. Does not say what the result is
- 0Progress reporting. Says nothing while it works
- 70When it triggers. States when to use, but not when not to
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Steps. 53 steps
- 100Failures and branches. 2 branches, has a failure section
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 3634 tokens
- 100Running it twice. Mutating operations check current state
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- low 15 top-level sections: this looks like several domains in one skill
- low The response is described with custom markup (11 tags): a typed call is more reliable
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
