Agent
Specialist for C# backend code within a vertical slice. Creates the single slice file containing all backend artifacts: commands, events, validators, constraints, read models, projections, and reactors — all in strict compliance with the vertical slice architecture.
Agent
Quality gate agent for Cratis-based projects. Reviews code against all project instruction files, checking architecture conformance, C# and TypeScript conventions, and vertical slice correctness before merge.
Agent
General-purpose coordinator agent for Cratis-based projects. Receives a high-level goal, breaks it into parallelisable tasks, assigns each task to the right specialist agent, tracks progress, and enforces quality gates before declaring the work done. Use this agent when a request spans multiple concerns (backend +…
Agent
Specialist for TypeScript/React frontend code within a vertical slice. Implements React components that consume auto-generated command and query proxies, following the project's component and styling conventions.
Agent
Top-level team orchestrator for Cratis-based projects. Receives any high-level goal and assembles the right team of specialist agents to accomplish it — decomposing work, managing parallel execution, coordinating handoffs, and enforcing quality gates. Use this agent as the entry point whenever multiple agents need to…
Agent
Performance-focused review agent for Cratis-based projects. Analyzes changed files for projection efficiency, query patterns, unnecessary allocations, React render overhead, and Chronicle anti-patterns before merge.
Agent
Orchestrates the implementation of one or more vertical slices. Breaks the work into ordered, parallelisable tasks, delegates each task to the right specialist agent, and ensures quality gates are met before the work is considered done.
Agent
Independent, read-only reviewer for typed Cratis repository investigations. Reviews evidence and repository-mode reasoning without applying application conventions to framework or client-library repositories.
Agent
Read-only investigator for Cratis application and framework repositories. Produces typed, evidence-backed findings without changing source, invoking mutating Chronicle operations, or assuming an application architecture.
Agent
Security gate agent for Cratis-based projects. Performs a structured security review of all changed files before merge, covering input validation, auth/authz, data exposure, secrets, event sourcing specifics, and frontend attack surface.
Agent
Implements a Cratis vertical slice end-to-end — all backend artifacts in one slice file, BDD specs in when/ folders, and the React surface (page and/or command dialog). Use for new slices and for non-trivial slice changes spanning backend and frontend.
Agent
Specialist for writing C# specs (the in-process scenario family) and TypeScript/React specs for vertical slices. Ensures every slice has comprehensive behavior coverage following the project's BDD conventions.
Skill Claude CodeCodex
Use this skill when asked to add a validation rule, business rule, or uniqueness constraint to an existing command in a Cratis-based project.
Skill Claude CodeCodex
Use this legacy local skill name when creating a strongly typed Cratis domain value or Chronicle event-source identity. Apply the same product-authoritative rules as the canonical cratis-fundamentals-concept skill; do not use it for enums, DTO-only values, arbitrary non-stream IDs, or event migration.
Skill Claude CodeCodex
Use this skill when creating a NEW Cratis documentation page under Documentation/ (tutorial, how-to, explanation, reference, or recipe). Handles where the file goes (which product repo), sidebar wiring (toc.yml + Diátaxis bucket), and verifying it renders. Trigger on add/create/write a new docs page, document a new…
Skill Claude CodeCodex
Use this skill when asked to add a database table, column, relationship, or other schema change via Entity Framework Core in a Cratis-based project.
Skill Claude CodeCodex
Use this skill when asked to add a Chronicle projection to a Cratis-based project. Favor model-bound projections by default, and only fall back to declarative/fluent IProjectionFor projections when model-bound attributes cannot express the behavior cleanly. Enforces the AutoMap-first rule and Chronicle-specific join…
Skill Claude CodeCodex
Use this skill when asked to add a Chronicle reactor (automation or translation) to a Cratis-based project. Reactors observe events and produce side effects.
Skill Claude CodeCodex
Use this skill when a read model genuinely needs an IReducerFor — when model-bound projection attributes and fluent IProjectionFor cannot express the state transition. Reducers are the last-resort escape hatch, not a default. Covers the admission checklist, method signatures, nullable-current handling, passivity, and…
Skill Claude CodeCodex
Use this skill when asked to add OpenTelemetry tracing to a class in a Cratis Chronicle Kernel project. Produces Traces.cs companion files using the [Span] source-generator pattern from Cratis.Traces, registers IActivitySource as a keyed DI service, and injects it into the target class.
Skill Claude CodeCodex
Use this skill for authentication, authorization, or identity in a Cratis Arc project — backend, frontend, or both. Covers identity providers (IProvideIdentityDetails), protecting commands/queries with authorization attributes, Microsoft Identity Platform, connecting backend identity to React, multi-tenant identity…
Skill Claude CodeCodex
Execute a Cratis Arc command from backend code via ICommandPipeline — the scopeless and scoped overloads, typed Execute , pre-flight Validate, and reading CommandResult. Use when a reactor, background job, scheduled task, integration test, or backend service needs to run a command without going through HTTP.
Skill Claude CodeCodex
Step-by-step guidance for creating a Cratis Arc command — [Command] record, Handle() method, CommandValidator, proxy generation, and React .use() hook with CommandDialog. Use when adding or creating a command, wiring up a form or button to the backend, working with IEventLog, CommandResult, CommandValidator…
Skill Claude CodeCodex
Reference for Cratis C# coding conventions — formatting, naming, records, nullable handling, exceptions, logging, and DI. Use whenever writing C# in a Cratis project, deciding between record vs class, checking naming rules, applying formatting conventions, handling null safety, creating exception types, or asking "how…
