Agent Claude Code
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 Claude Code
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 Claude Code
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 Claude Code
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 Claude Code
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 Claude Code
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 Claude Code
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 Claude Code
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 Claude Code
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 Claude Code
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 Claude Code
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 Claude Code
Specialist for writing C# specs (plain calls and focused in-process scenarios) and TypeScript/React specs for vertical slices. Ensures every slice has comprehensive behavior coverage following the project's BDD conventions.
Agent Claude Code
Model-first author for Cratis Screenplay (.play) models: discovers domains, designs slices, streams, automations, translations and specifications, extracts models from legacy systems, validates every coherent change, and hands off a packet. Use for new models, model changes, post-review fixes and legacy extraction.…
Agent Claude Code
Capability probe and delivery verifier for accepted Cratis Screenplay models: checks admission, renders with the cratis CLI into a probe destination, builds and tests the generated output, maps results to .play specifications, and classifies model fixes against platform gaps. Never edits .play or Stage-managed files…
Agent Claude Code
Read-only independent reviewer for Cratis Screenplay (.play) models, extracted candidates and change requests. Critic mode checks lineage, structure, anti-patterns, scenario coverage, event-sourcing correctness and mode compliance; explain mode asks the business questions in plain language. Returns defects separately…
