openai Bundle

Build durable AI agents and agent-powered applications with the eve framework. Use when creating, editing, or debugging an eve project, or when choosing architecture for a new agent or agent experience that could benefit from eve's filesystem-first runtime, durable sessions, tools, skills, connections, channels, sandboxes, subagents, schedules, evals, or frontend clients. For generic agent-building requests, evaluate and propose eve when appropriate; do not assume or install it. Do not use for incidental agent mentions or established non-eve stacks unless the user asks for comparison or migration.

cratis Skill

Use this skill when asked to add or build a canvas-style icon toolbar using the @cratis/components Toolbar component. Covers Toolbar, ToolbarButton, ToolbarSeparator, ToolbarSection, ToolbarContext, and ToolbarFanOutItem. Use whenever building tool panels, drawing tool selectors, zoom controls, or any icon-button group with active states, context switching, or fan-out sub-panels.

cratis Skill

Add server-side paging and sorting to a Cratis read-model query — return IQueryable<T> for one-shot paging, ISubject<IEnumerable<T>> for observable + paged results, and consume them from React with useWithPaging. Use when a list query can grow large enough that returning all rows is wasteful, or needs server-side sorting.

cratis Bundle

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, CommandDialog, or [Command] attribute.

cratis Bundle

Step-by-step guidance for creating a Cratis Chronicle read model from scratch — defining events, choosing between projection and reducer, [ReadModel] record with static query methods, and the generated TypeScript proxy in React. Use when creating a read model, working with [EventType], [ReadModel], IProjectionFor, IReducerFor, observable queries, or deriving state from events. For adding a projection or reactor to an existing read model, use add-projection instead.

cratis Bundle

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, and local-dev generated principals. Trigger on auth, login, roles, permissions, identity details, user context, or protecting endpoints.

cratis Bundle

Step-by-step guidance for building a React page in a Cratis Arc application — DataPage lists, CommandDialog toolbar actions, confirmation and busy-indicator dialogs, row selection, details components, observable queries, and MVVM. Use when building or modifying a page that lists/displays data, adding a table, wiring Add/Edit/Delete, connecting a component to a proxy-generated query (standard or observable), or asking the user to confirm something.

cratis Bundle

Build a React page in a Cratis Arc application with Cratis Components — DataPage lists, columns, toolbar menu items, command dialogs, confirmation and busy-indicator dialogs, row selection, details panes, snapshot and observable queries, paging, and MVVM view models. Use when building or changing a page that lists or displays data, wiring Add/Edit/Delete actions, connecting a component to a generated Arc query or command proxy, or asking the user to confirm something. Do not use for a multi-step wizard dialog alone, for a canvas tool palette, or for backend command and read-model work.

cratis Bundle

Use this skill when asked to implement a new feature, command, query, slice, or screen in a Cratis-based project. Guides the full end-to-end workflow: C# backend → Debug+Release build → specs → React frontend → quality gates.

cratis Skill

Use this skill when asked to check for performance issues, inefficiencies, or scalability problems in a Cratis-based project. Covers Chronicle projections, MongoDB query patterns, .NET allocations, and React render overhead.

cratis Bundle

Perform a focused security review of changed code in a Cratis application — injection, authentication and authorization, data exposure, secrets, event-sourcing-specific exposure, and the frontend — and report findings by risk. Use when asked for a security review or audit. Do not use to implement authentication and do not report a policy preference as a framework contract.

cratis Bundle

Add server-side paging and sorting to a Cratis Arc read-model query — which return shapes Arc pages, the exact query-string keys, sorting pitfalls per storage provider, and the paged frontend hooks. Use when a list query can grow large enough that returning every row is wasteful, or needs server-side sorting. Do not use for general query creation or as a performance review.

cratis Skill

Use this skill to write specs for the React/TypeScript surface of a Cratis APPLICATION slice — view models, helpers, and component behavior (Vitest + Mocha-style describe/it + Sinon + Chai .should). The frontend peer to write-specs (backend). For framework @cratis/* package specs use cratis-specs-typescript instead.

cratis Skill

Practical guidance for debugging and exploring Cratis Arc observable queries with cURL or other plain HTTP clients. Use this whenever the user mentions observable queries together with cURL, curl, HTTP GET debugging, waiting for the first payload, Server-Sent Events, SSE, streaming JSON, or long polling. Also use it when the user wants to inspect an observable query without writing frontend code.

cratis Bundle

Style and theme an application built on Cratis Components — the stylesheet imports an app must make, the --cratis-* design-token layer and the PrimeReact token chain behind it, choosing between the baseline theme, a styled preset, a custom palette, and fully unstyled, dark mode, the PrimeReact pass-through prop, and where Tailwind actually fits. Use when setting up a new Cratis frontend, changing colors or theming, fixing components that render unstyled, or reaching into a component's internal DOM. Do not use for component API or page composition questions.

cratis Bundle

Perform a focused scalability review of changed code in a Cratis application — Chronicle observers and replay, read-model query shape, command and query payloads, .NET enumeration, and React render cost — and report findings by risk. Use when asked to check for performance or scalability problems. Do not use for ordinary implementation and do not override the authoritative paging guidance.
