assistant-ui

Use this skill to implement or debug assistant-ui integration end to end: CLI setup, runtime wiring, UI primitives, tool UI, and migration-safe upgrades. Load only the reference file needed for the current subtask to keep context focused.

Determine whether the request is setup, runtime wiring, primitives, tools, cloud persistence, or migration. If the request includes explicit exclusion language (without/no/not assistant-ui), stop and do not use this skill.

Choose AI SDK, LangGraph, or external-store path before editing components.

Build and maintain assistant-ui based React chat apps with reliable setup, runtime selection, LangGraph wiring, tool UI integration, and upgrade workflows. Use when tasks explicitly involve `assistant-ui` dependencies or APIs, including `assistant-ui` CLI commands (`create/init/add/update/upgrade/codemod`), `@assistant-ui/*` providers/runtimes, `AssistantRuntimeProvider`, Thread/Composer primitives, cloud persistence, or tool rendering behavior. Do not use for generic React chat work, backend-only LangGraph tasks, or non-assistant-ui UI work. If the prompt explicitly says without/no/not assistant-ui, do not trigger this skill.
