smoke-test

Smoke Test Skill

Creates a new Mastra project using create-mastra@<tag> and performs smoke testing of the Mastra Studio in Chrome.

This skill is for Claude Code with Chrome MCP server. For MastraCode with built-in browser tools, use mastracode-smoke-test instead.

Usage

/smoke-test --directory <path> --name <project-name> --tag <version> [--pm <package-manager>] [--llm <provider>]
/smoke-test -d <path> -n <project-name> -t <version> [-p <package-manager>] [-l <provider>]

Parameters

Parameter	Short	Description	Required	Default
--directory	-d	Parent directory where project will be created	Yes	-
--name	-n	Project name (will be created as subdirectory)	Yes	-
--tag	-t	Version tag for create-mastra (e.g., latest, alpha, 0.10.6)	Yes	-
--pm	-p	Package manager: npm, yarn, pnpm, or bun	No	npm
--llm	-l	LLM provider: openai, anthropic, groq, google, cerebras, mistral	No	openai

Examples

# Minimal (required params only)
/smoke-test -d ~/projects -n my-test-app -t latest

# Full specification
/smoke-test --directory ~/projects --name my-test-app --tag alpha --pm pnpm --llm anthropic

# Using short flags
/smoke-test -d ./projects -n smoke-test-app -t 0.10.6 -p bun -l openai

Step 0: Parameter Validation (MUST RUN FIRST)

CRITICAL: Before proceeding, parse the ARGUMENTS and validate:

1. Parse arguments from the ARGUMENTS string provided above
2. Check required parameters:
   • --directory or -d: REQUIRED - fail if missing
   • --name or -n: REQUIRED - fail if missing
   • --tag or -t: REQUIRED - fail if missing
3. Apply defaults for optional parameters:
   • --pm or -p: Default to npm if not provided
   • --llm or -l: Default to openai if not provided
4. Validate values:
   • pm must be one of: npm, yarn, pnpm, bun
   • llm must be one of: openai, anthropic, groq, google, cerebras, mistral
   • directory must exist (or will be created)
   • name should be a valid directory name (no spaces, special chars)

If validation fails: Stop and show usage help with the missing/invalid parameters.

If -h or --help is passed: Show this usage information and stop.

Prerequisites

This skill requires the Chrome MCP server (Claude-in-Chrome) for browser automation. Ensure it's configured and running.

The Chrome MCP server provides tools like tabs_create_mcp, tabs_context_mcp, navigate_mcp, click_mcp, type_mcp, and screenshot_mcp.

Execution Steps

Step 1: Create the Mastra Project

Run the create-mastra command with explicit parameters to avoid interactive prompts:

# For npm
npx create-mastra@<tag> <project-name> --no-git --llm <llmProvider> --timeout 120000

# For yarn
yarn dlx create-mastra@<tag> <project-name> --no-git --llm <llmProvider> --timeout 120000

# For pnpm
pnpm create mastra@<tag> <project-name> --no-git --llm <llmProvider> --timeout 120000

# For bun
bunx create-mastra@<tag> <project-name> --no-git --llm <llmProvider> --timeout 120000

-c/--components and -e/--example were removed and must not be used. -l/--llm is still supported and is the flag used above. Use the managed template by default, --empty for a deliberately empty project, or --template <template> for a specific template. If a flag is rejected, inspect the initializer's help rather than retrying a legacy command: npm create mastra@<tag> -- --help, npx create-mastra@<tag> --help, pnpm create mastra@<tag> --help, yarn dlx create-mastra@<tag> --help, or bunx create-mastra@<tag> --help.

Wait for the installation to complete. This may take 1-2 minutes depending on network speed.

Step 2: Verify Project Structure

After creation, verify the project has:

• package.json with mastra dependencies
• src/mastra/index.ts exporting a Mastra instance
• .env file (may need to be created)

Step 2.5: Add Browser Agent for Browser Testing

To test browser functionality, add a browser-enabled agent:

1. Install browser packages:

<pm> add @mastra/stagehand
# or for deterministic browser automation:
<pm> add @mastra/agent-browser

2. Create browser-agent.ts in src/mastra/agents/:

import { Agent } from '@mastra/core/agent';
import { Memory } from '@mastra/memory';
import { StagehandBrowser } from '@mastra/stagehand';

export const browserAgent = new Agent({
  id: 'browser-agent',
  name: 'Browser Agent',
  instructions: `You are a helpful assistant that can browse the web to find information.`,
  model: '<provider>/<model>', // e.g., 'openai/gpt-4o'
  memory: new Memory(),
  browser: new StagehandBrowser({
    headless: false,
  }),
});

3. Update index.ts to register the browser agent:

import { browserAgent } from './agents/browser-agent';

// In Mastra config:
agents: { weatherAgent, browserAgent },

Step 3: Configure Environment Variables

Based on the selected LLM provider, check for the required API key:

Provider	Required Environment Variable
openai	OPENAI_API_KEY
anthropic	ANTHROPIC_API_KEY
groq	GROQ_API_KEY
google	GOOGLE_GENERATIVE_AI_API_KEY
cerebras	CEREBRAS_API_KEY
mistral	MISTRAL_API_KEY

Check in this order:

1. Check global environment first: Run echo $<ENV_VAR_NAME> to see if the key is already set globally

   • If set globally, the project will inherit it - no .env file needed
   • Skip to Step 4

2. Check project .env file: If not set globally, check if .env exists in the project and contains the key

3. Ask user only if needed: If the key is not available globally or in .env:

   • Ask the user for the API key
   • Create the .env file with the provided key

Only check for the ONE key matching the selected provider - don't check for all providers.

Step 4: Start the Development Server

Navigate to the project directory and start the dev server:

cd <directory>/<project-name>
<packageManager> run dev

The server typically starts on http://localhost:4111. Wait for the server to be ready before proceeding.

Step 5: Smoke Test the Studio

Use the Chrome browser automation tools to test the Mastra Studio.

5.1 Initial Setup

1. Get browser context using tabs_context_mcp
2. Create a new tab using tabs_create_mcp
3. Navigate to http://localhost:4111
