AgenticStream Playwright Reporter

A high-density, token-efficient Playwright reporter designed for autonomous AI coding agents.

Features

- Zero-Latency: Streams to stdout, no file I/O
- Token Efficiency: "Silence on Success" - passing tests emit nothing
- High-Signal: Captures stack traces, console logs, attachments
- Overflow Protection: Truncates after N failures to prevent context exhaustion
- Extensible: Custom hint patterns and output streams

Installation

``bash
npm install @looted/agentic-reporter
`

Usage

`typescript
// playwright.config.ts
import { defineConfig } from '@playwright/test';

export default defineConfig({
reporter: process.env['AGENTIC_REPORTER']
? [['@looted/agentic-reporter', { maxFailures: 5 }]]
: [['html', { open: 'never' }]],
});
`

Options

| Option | Type | Default | Description |
| ---------------------------- | -------------- | ------- | --------------------------------------------- |
| maxFailures | number/boolean | false | Max failures before stopping execution |
| maxStackFrames | number | 8 | Stack trace depth |
| maxLogLines | number | 5 | Console log lines |
| maxLogChars | number | 500 | Max log characters |
| includeAttachments | boolean | true | Include trace/screenshot paths |

| getReproduceCommand | function | - | Custom callback to generate reproduce command |

$3

You can customize the reproduce command output by providing a callback function. This is useful for wrapping the Playwright command in a shell script or custom runner.

`typescript
import { defineConfig } from '@playwright/test';
import { agenticReporter } from '@looted/agentic-reporter';

export default defineConfig({
reporter: [
agenticReporter({
getReproduceCommand: ({ file, line, project }) => {
return ./run-e2e.sh ${file}:${line} --project=${project};
},
}),
],
});
`
