AI Agent Skills: Cratis Application Slice Backend Guide
The AI Agent Skills: Cratis Application Slice Backend Guide specifies the backend behavior of an event-sourced Cratis application slice using the in-process scenario family. It is designed for situations where you are adding or changing backend behavior within applications built on Cratis, excluding framework library specifications or frontend behavior.
What this skill does
- Utilizes the Cratis scenario family, including CommandScenario, EventScenario, ReadModelScenario, and ReactorScenario, to specify what a Cratis application slice does in the pipeline it actually runs on.
- Details the necessary aspects to cover for each slice type and indicates where the specification files are located.
- Executes real Arc and Chronicle code paths in-process, avoiding the use of HTTP, fixtures, or servers, to provide a specification that reflects the slice's behavior rather than its class structure.
Who it is for
This skill is intended for developers and development teams utilizing AI coding agents like Claude Code, Cursor, and Codex. It benefits those who need to define or alter backend behaviors of Cratis application slices in a precise and structured manner.
Use cases
- Developers defining new backend behaviors for a Cratis application slice without affecting frontend interactions.
- Teams needing to adjust existing backend specifications to accommodate changes in application logic or requirements.
- Engineering teams conducting in-process testing of backend specifications to ensure correct application slice behavior.
Technical details
- Utilizes the Cratis.Arc.Testing package (v22.16.0) for CommandScenario and CommandResult assertions.
- Employs the Cratis.Arc.Chronicle.Testing package (v22.16.0) with features like Given, EventLog, and AppendedEvents for test scenarios.
- Leverages the Cratis.Chronicle.Testing package (v18.3.0) for EventScenario, ReadModelScenario, and ReactorScenario tests.
- Incorporates Cratis.Specifications.XUnit (v4.x) for Specification base and ShouldXxx assertions, facilitating structured backend specifications.

Here's what buyers say about the skills they use every day.
Ran it on a client's Google Ads account and it flagged wasted spend we'd been missing for months. Paid for itself on day one.
Optimize Ad Spend: Ad Account AuditorWe finally caught broken conversion tags before launch instead of after. The pre-launch checklist alone is worth the price.
Optimize Conversion Tracking: Pre-Launch QADropped it into Claude Code and my LCP went from 4.1s to 1.9s in an afternoon. It explains every fix it suggests, so I actually learned something too.
Optimize Core Web VitalsOur agency uses it as the final review step on every PR now. It catches security issues our linters never did.
Optimize Your Code: Best Practices & SecurityMade WCAG 2.2 compliance actually manageable. It walked through our whole storefront and produced a fix list our devs could work from directly.
Enhance Web Accessibility: WCAG 2.2As an expat freelancer in France, the DGFIP simulation saved me a very expensive appointment with an accountant. Incredibly thorough.
AI Tax Audit Skill: DGFIP Fiscal ControlWorks with both Cursor and Claude Code exactly as advertised. Setup took less than five minutes with the included README.
Optimize Profits: AI Conversion Value MapperInstant delivery, clean files, clear docs. This is how digital products should be sold. Already bought three more skills.
AI Comptable: French AccountingSupport answered my install question within a couple of hours on a Sunday. The skill itself has become part of my daily workflow.
