Logging / observability: what the agents install

Install share by product

Install share counts the product each answer installed first. Mentioned counts answers that named it anywhere, picked or not. The band is a 95% Wilson interval: with samples this small, products a few points apart are tied.

Prompt by prompt

Each chip is one answer (2 samples per model). None means the model built it by hand or didn't choose.

What the models wrote

afana
Create a `docker-compose.yml` file to spin up the logging backend and dashboard:

```yaml
version: "3.8"
services:
  loki:
    image: grafana/loki:latest
    ports:
      - "3100:3100"
    command: -config.file=/etc/loki/local-config.yaml
    # Use standard json-file for Loki itself to prevent routing loops
    logging:
      driver: "json-file"

  grafana:
    image: grafana/grafana:latest
    ports:
      - "

one:latest
```

### 2. Install OpenTelemetry Dependencies
Run this in all three of your TypeScript service directories:
```bash
npm install @opentelemetry/sdk-node @opentelemetry/api @opentelemetry/auto-instrumentations-node @opentelemetry/exporter-trace-otlp-http
```

### 3. Create the Tracing Setup Code
Add a `tracing.ts` file to the root of **each** service. Change the `serviceName` for each respective service (e.

()` to attach a unique `traceId` to every request and log.

### 1. Install Dependencies
Run this in your project root:
```bash
npm install pino pino-http
npm install pino-pretty --save-dev
```

### 2. Configure Logger (`logger.js`)
Create a centralized logger configuration.
```javascript
const pino = require('pino');

const isProduction = process.env.NODE_ENV === 'production';

const logger = pino({
  level: process.
