LLMs were adding query schemas but not running npm run typegen, causing TypeScript errors like "query key not assignable to type". Made Step 3 explicit: run typegen after any schema change. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

The hook's return type doesn't infer from QueryRegistry, so data is typed as {}.
Without manual casting, TypeScript errors like "Property 'map' does not exist" occur.
TODO: File SDK improvement PR to fix useAnalyticsQuery type inference
from QueryRegistry so casting isn't needed.

| **To refresh TypeScript types after adding queries:** | ||
| - Run `npm run typegen` OR run `npm run dev` - both auto-generate type definitions in `client/src/appKitTypes.d.ts` | ||
| - DO NOT manually edit `appKitTypes.d.ts` | ||
| **⚠️ CRITICAL: Always run `npm run typegen` after modifying `config/queries/schema.ts`** |

There was a problem hiding this comment.
The schema.ts file doesn't exist anymore, only the appKitTypes file

The most critical workflow steps were only in template docs, which agents sometimes skip. Adding to MCP guidance ensures agents see this during databricks_discover call: - npm run typegen required after schema changes - data casting required for useAnalyticsQuery - chart components don't accept children Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

AppKit-specific guidance now lives in skills/apps/appkit/. target_apps.tmpl focuses on validation, deployment, and operational commands only. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Move AppKit documentation from appkit repo llms.txt to CLI skills. This establishes CLI as the single source of truth for agent guidance. Includes: - SKILL.md: Overview, hard rules, quick start - appkit-backend.md: Server, analytics, plugins, caching - appkit-frontend.md: Charts, hooks, UI components, SSE - appkit-scaffolding.md: Project setup, type generation Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
