While using MCP tools should be extracted from the MCP client and not from the session. Only during native tool use we should extract it from the session.

If we are updating the core package, let's use catalog itself?

Mini models doesn't perform well, can we use latest models?

Sure, that can be changed. I had used gpt-4o-mini because it was the one already introduced in src/stream.ts by 9e002c5#diff-534cbbffb3adc765fa52727a5fb7286ee4fbeb0a846af5aacf1de20b903a0d29 3 weeks ago.
Is gpt-5.2 ok?

For vercel ai sdk 6, the primary feature is their agents, can we have an example using their Agents feature?
import { ToolLoopAgent } from 'ai';
import { weatherTool } from '@/tools/weather';
export const weatherAgent = new ToolLoopAgent({
model: 'anthropic/claude-sonnet-4.5',
instructions: 'You are a helpful weather assistant.',
tools: {
weather: weatherTool,
},
});
const result = await weatherAgent.generate({
prompt: 'What is the weather in San Francisco?',
});

Environment variables not loaded after dotenv removal
The dotenv import and dotenv.config() call were removed from stream.ts, but the code still accesses process.env.COMPOSIO_API_KEY on line 10. Unlike other example files in the project (such as openai/src/chat-completions.ts) that properly call dotenv.config() before accessing environment variables, this file no longer loads the .env file. For users running this example with Node.js (rather than Bun, which auto-loads .env files), the COMPOSIO_API_KEY will be undefined, causing the example to fail.

Developer username hardcoded in example files
The example files use the developer's personal username 'jkomyno' as the user identifier in composio.create() calls. Other examples like ai.ts consistently use the generic placeholder 'test-user-id'. Using a specific developer's username in documentation examples is inconsistent and may confuse users following the examples.
