Appkit template uses getRequestContext which doesn't exist in @databricks/appkit

[keugenek]

Summary

The appkit template in experimental/aitools/templates/appkit/ imports getRequestContext from @databricks/appkit, but this function does not exist in any published version of the package (checked 0.1.1 through 0.1.5).

Reproduction

Apps generated using the MCP server with the appkit template fail at runtime with:

file:///tmp/.../dist/server/trpc.js:4
import { getRequestContext } from '@databricks/appkit';
         ^^^^^^^^^^^^^^^^^
SyntaxError: Named export 'getRequestContext' not found. The requested module '@databricks/appkit' is a CommonJS module...

Affected File

experimental/aitools/templates/appkit/template/{{.project_name}}/server/trpc.ts:

import { getRequestContext } from '@databricks/appkit';
// ...
const { serviceDatabricksClient: client } = getRequestContext();

Current @databricks/appkit exports (v0.1.5)

export { CacheManager, Plugin, SeverityNumber, SpanStatusCode, 
         analytics, appKitTypesPlugin, createApp, isSQLTypeMarker, 
         server, sql, toPlugin };

No getRequestContext export exists.

Suggested Fix

Either:

1. Add getRequestContext to the @databricks/appkit package
2. Update the template to use the existing appkit APIs
3. If this is an internal/unpublished feature, document the required appkit version or provide a workaround

Environment

• CLI version: snapshot (main branch)
• @databricks/appkit: all versions 0.1.1-0.1.5 tested
• Platform: Databricks Runtime 16.2.x

Additional Finding

The CLI's appkit template at experimental/aitools/templates/appkit/ is out of sync with the official template in the databricks/appkit repository.

Key Differences

Aspect	AppKit Repo Template	CLI Template
SDK Version	@databricks/appkit: 0.1.4	0.1.2
Server Pattern	Simple createApp() + plugins	Complex tRPC router
tRPC	Not used	Uses tRPC with getRequestContext

AppKit Repo Server (correct)

// template/server/server.ts
import { createApp, server } from '@databricks/appkit';

createApp({
  plugins: [server()],
}).catch(console.error);

CLI Template Server (broken)

// experimental/aitools/templates/appkit/template/{{.project_name}}/server/trpc.ts
import { getRequestContext } from '@databricks/appkit';  // ❌ Doesn't exist
const { serviceDatabricksClient: client } = getRequestContext();

Suggested Fix

Align the CLI template with the official appkit repo template, which uses the simpler plugin-based architecture without the non-existent getRequestContext API.
