Ultimate Mastra Development Toolkit

A comprehensive skill for developing, managing, and debugging Mastra Framework applications. This toolkit provides six major capability areas to accelerate Mastra development with automated scaffolding, server management, and expert guidance.

Quick Start

# Check Mastra server status
$mastra-dev server status

# Analyze current Mastra setup
$mastra-dev analyze

# Create a new agent
$mastra-dev create-agent --name "contract-analyzer" --model "anthropic/claude-3-5-sonnet-20241022"

# Create a new workflow
$mastra-dev create-workflow --name "form-generation" --description "Auto-fill government forms"

# Start Mastra server
$mastra-dev server start

# Start Mastra Studio (observability UI)
$mastra-dev studio start

What This Skill Does

This skill answers critical questions for Mastra developers:

1. How do I create a new Mastra agent?

$mastra-dev create-agent \
  --name "proposal-writer" \
  --model "openai/gpt-4-turbo" \
  --description "Expert technical writer for government proposals" \
  --instructions "You are an expert technical writer..." \
  --tools "sam-gov-lookup,company-data"

What happens:

Generates apps/mastra/src/agents/proposal-writer.ts with proper structure
Registers agent in apps/mastra/src/config/mastra.config.ts
Follows Mastra best practices with TypeScript typing
Includes Zod schemas for validation
Auto-imports required dependencies

2. How do I build a workflow with multiple steps?

# Create workflow
$mastra-dev create-workflow \
  --name "contract-analysis" \
  --description "Analyze government contract for risks"

# Add steps sequentially
$mastra-dev add-step \
  --workflow "contract-analysis" \
  --step-name "extract-text" \
  --step-type "transform" \
  --input-schema '{"documentUrl": "string"}' \
  --output-schema '{"text": "string"}'

$mastra-dev add-step \
  --workflow "contract-analysis" \
  --step-name "identify-clauses" \
  --step-type "transform" \
  --input-schema '{"text": "string"}' \
  --output-schema '{"clauses": "array"}'

# Test the workflow
$mastra-dev test-workflow \
  --name "contract-analysis" \
  --input '{"documentUrl": "https://example.com/contract.pdf"}'

What happens:

Creates workflow file at apps/mastra/src/workflows/contract-analysis.ts
Generates steps with proper DAG composition (.then(), .parallel(), .branch())
Validates schema compatibility between steps
Registers workflow in MCP server configuration
Provides execution testing capability

3. How do I integrate external MCP servers?

# Add Wikipedia MCP server
$mastra-dev mcp add-client \
  --name "wikipedia" \
  --command "npx" \
  --args "-y,wikipedia-mcp"

# Add remote HTTP MCP server
$mastra-dev mcp add-client \
  --name "weather" \
  --url "https://server.smithery.ai/@smithery-ai/national-weather-service/mcp"

# Configure MCP server to expose workflows
$mastra-dev mcp configure-server \
  --agents "proposal-writer" \
  --workflows "contract-analysis"

# List all configured MCP servers
$mastra-dev mcp list-servers

# Test MCP connection
$mastra-dev mcp test --server "wikipedia"

What happens:

Updates apps/mastra/src/config/mcp.config.ts with MCPClient configuration
Supports both stdio (local) and HTTP (remote) transports
Configures MCPServer to expose Mastra agents/workflows as tools
Validates MCP connections and tool availability

4. How do I debug workflow execution?

# Debug specific workflow execution
$mastra-dev debug-workflow \
  --name "contract-analysis" \
  --execution-id "abc-123-def-456"

# Show workflow DAG visualization
$mastra-dev show-graph --workflow "contract-analysis"

# Validate all Mastra configurations
$mastra-dev validate

# View detailed logs
$mastra-dev server logs --tail 100

What happens:

Queries mastra.workflow_executions table for execution state
Retrieves step-by-step logs from mastra.step_execution_logs
Identifies failed steps with error details
Shows input/output data for each step
Generates ASCII visualization of workflow DAG
Validates schema compatibility and configuration correctness

5. What agents/workflows/tools are currently defined?

# List all agents
$mastra-dev list-agents

# Analyze specific agent
$mastra-dev analyze-agent --name "proposal-writer"

# List all workflows
$mastra-dev list-workflows

# List all tools
$mastra-dev list-tools

# Comprehensive analysis
$mastra-dev analyze

What happens:

Scans apps/mastra/src/agents/*.ts for agent definitions
Scans apps/mastra/src/workflows/*.ts for workflows
Scans apps/mastra/src/tools/*.ts for tools
Parses TypeScript files to extract configurations
Shows registration status in mastra.config.ts
Displays model providers, tool usage, and dependencies

Features

1. Agent Management

Create, list, and analyze Mastra agents with intelligent scaffolding.

Commands:

# Create new agent

Commands:

# Create new workflow
$mastra-dev create-workflow \
  --name <workflow-name> \
  --description <description> \
  [--input-schema <json-schema>] \
  [--output-schema <json-schema>]

# Add step to workflow
$mastra-dev add-step \

  --step-name <step-name> \
  --step-type <transform|api-call|agent-call|parallel|branch> \
  [--input-schema <json-schema>] \
  [--output-schema <json-schema>]

# Test workflow execution
$mastra-dev test-workflow \
  --name <workflow-name> \
  --input <json-input>

# List all workflows
$mastra-dev list-workflows

Example - Build Form Generation Workflow:

# Step 1: Create workflow
$mastra-dev create-workflow \
  --name "form-generation" \
  --description "Auto-fill government forms from SAM.gov data" \
  --input-schema '{"opportunityId": "string"}' \
  --output-schema '{"formData": "object", "pdfUrl": "string"}'

# Step 2: Add fetch step
$mastra-dev add-step \
  --workflow "form-generation" \
  --step-name "fetch-opportunity" \
  --step-type "api-call" \
  --input-schema '{"opportunityId": "string"}' \
  --output-schema '{"opportunity": "object"}'

# Step 3: Add transform step
$mastra-dev add-step \
  --workflow "form-generation" \
  --step-name "extract-data" \
  --step-type "transform" \
  --input-schema '{"opportunity": "object"}' \
  --output-schema '{"formData": "object"}'

# Step 4: Add PDF generation step
$mastra-dev add-step \
  --workflow "form-generation" \
  --step-name "generate-pdf" \
  --step-type "transform" \
  --input-schema '{"formData": "object"}' \
  --output-schema '{"pdfUrl": "string"}'

# Test the workflow
$mastra-dev test-workflow \
  --name "form-generation" \
  --input '{"opportunityId": "abc-123"}'

Generated File: apps/mastra/src/workflows/form-generation.ts

import { createWorkflow, createStep } from '@mastra/core/workflows';
import { z } from 'zod';

const fetchOpportunityStep = createStep({
  id: 'fetch-opportunity',
  inputSchema: z.object({ opportunityId: z.string() }),
  outputSchema: z.object({ opportunity: z.any() }),
  execute: async ({ inputData }) => {
    // API call implementation
    const response = await fetch(`https://api.sam.gov/opportunities/${inputData.opportunityId}`);
    return { opportunity: await response.json() };
  }
});

const extractDataStep = createStep({
  id: 'extract-data',
  inputSchema: z.object({ opportunity: z.any() }),
  outputSchema: z.object({ formData: z.any() }),
  execute: async ({ inputData }) => {
    // Transform logic
    return { formData: { /* extracted data */ } };
  }
});

const generatePdfStep = createStep({
  id: 'generate-pdf',
  inputSchema: z.object({ formData: z.any() }),
  outputSchema: z.object({ pdfUrl: z.string() }),
  execute: async ({ inputData }) => {
    // PDF generation
    return { pdfUrl: 'https://example.com/form.pdf' };
  }
});

export const formGenerationWorkflow = createWorkflow({
  id: 'form-generation',
  description: 'Auto-fill government forms from SAM.gov data',
  inputSchema: z.object({ opportunityId: z.string() }),
  outputSchema: z.object({ formData: z.any(), pdfUrl: z.string() })
})
  .then(fetchOpportunityStep)
  .then(extractDataStep)
  .then(generatePdfStep)
  .commit();

Control Flow Patterns:

Sequential: .then(stepA).then(stepB).then(stepC)
Parallel: .parallel([stepA, stepB, stepC])
Conditional: .branch({ when: (data) => data.score > 0.8, then: highPath, otherwise: lowPath })

3. Tool Management

Create reusable tools with schema validation and type safety.

Commands:

# Create new tool
$mastra-dev create-tool \
  --name <tool-name> \
  --description <description> \
  [--input-schema <json-schema>] \
  [--output-schema <json-schema>]

# List all tools
$mastra-dev list-tools

# Test tool execution
$mastra-dev test-tool \
  --name <tool-name> \
  --input <json-input>

Example - Create PDF Generator Tool:

$mastra-dev create-tool \
  --name "pdf-generator" \
  --description "Generate PDF from template and data" \
  --input-schema '{"template": "string", "data": "object"}' \
  --output-schema '{"pdfUrl": "string", "size": "number"}'

Generated File: apps/mastra/src/tools/pdf-generator.ts

import { createTool } from '@mastra/core/tools';
import { z } from 'zod';

export const pdfGeneratorTool = createTool({
  id: 'pdf-generator',
  description: 'Generate PDF from template and data',
  inputSchema: z.object({
    template: z.string(),
    data: z.record(z.any())
  }),
  outputSchema: z.object({
    pdfUrl: z.string(),
    size: z.number()
  }),
  execute: async ({ inputData }) => {
    // PDF generation logic
    const pdfUrl = await generatePdf(inputData.template, inputData.data);
    return {
      pdfUrl,
      size: 12345
    };
  }
});

4. Server Management

Control Mastra server lifecycle and monitor logs.

Commands:

# Start Mastra server
$mastra-dev server start

# Stop Mastra server
$mastra-dev server stop

# Check server status
$mastra-dev server status

# View server logs
$mastra-dev server logs [--tail <lines>]

# Start Mastra Studio (observability UI)
$mastra-dev studio start

Example - Server Management Workflow:

# Check if server is running
$mastra-dev server status
# Output: ❌ Mastra server is not running (port 6000)

# Start the server
$mastra-dev server start
# Output: ✅ Mastra server started on port 6000 (PID: 12345)

# Verify it's running
$mastra-dev server status
# Output: ✅ Mastra server is running on port 6000 (PID: 12345)
#         Uptime: 5 minutes
#         Memory: 245 MB

# View recent logs
$mastra-dev server logs --tail 50
# Output: [Shows last 50 lines from apps/mastra/logs/mastra.log]

# Start Mastra Studio for observability
$mastra-dev studio start
# Output: ✅ Mastra Studio started on http://localhost:4111
#         Connected to Mastra API at http://localhost:6000

What Happens:

server start: Launches Mastra Express server via npm run dev:mastra
server stop: Gracefully terminates process via SIGTERM
server status: Checks port 6000, parses ps aux | grep mastra
server logs: Tails from apps/mastra/logs/mastra.log
studio start: Launches Mastra Studio CLI on port 4111

5. MCP Management

Configure Model Context Protocol integration for external tool access.

Commands:

# Add MCPClient for consuming external servers
$mastra-dev mcp add-client \
  --name <server-name> \
  --command <command> \
  [--args <comma-separated-args>] \
  [--url <http-url>]

# Configure MCPServer to expose Mastra tools
$mastra-dev mcp configure-server \
  [--agents <comma-separated-agent-ids>] \
  [--workflows <comma-separated-workflow-ids>] \
  [--tools <comma-separated-tool-ids>]

# List all MCP servers
$mastra-dev mcp list-servers

# Test MCP server connection
$mastra-dev mcp test --server <server-name>

Example - Add External MCP Servers:

# Add local stdio MCP server (Wikipedia)
$mastra-dev mcp add-client \
  --name "wikipedia" \
  --command "npx" \
  --args "-y,wikipedia-mcp"

# Add remote HTTP MCP server (Weather)
$mastra-dev mcp add-client \
  --name "weather" \
  --url "https://server.smithery.ai/@smithery-ai/national-weather-service/mcp"

# Add Puppeteer for browser automation
$mastra-dev mcp add-client \
  --name "puppeteer" \
  --command "npx" \
  --args "-y,@modelcontextprotocol/server-puppeteer"

Updated Configuration: apps/mastra/src/config/mcp.config.ts

import { MCPClient } from '@mastra/mcp';

export const mcpClient = new MCPClient({
  id: 'mastra-mcp-client',
  servers: {
    wikipedia: {
      command: 'npx',
      args: ['-y', 'wikipedia-mcp']
    },
    weather: {
      url: new URL('https://server.smithery.ai/@smithery-ai/national-weather-service/mcp')
    },
    puppeteer: {
      command: 'npx',
      args: ['-y', '@modelcontextprotocol/server-puppeteer']
    }
  }
});

Example - Expose Mastra Workflows via MCP:

# Configure MCPServer to expose workflows
$mastra-dev mcp configure-server \
  --workflows "form-generation,contract-analysis"

Updated Configuration:

import { MCPServer } from '@mastra/mcp';
import { formGenerationWorkflow } from '../workflows/form-generation.js';
import { contractAnalysisWorkflow } from '../workflows/contract-analysis.js';

export const mastraMcpServer = new MCPServer({
  id: 'mastra-workflows',
  name: 'Mastra Workflow Engine',
  version: '1.0.0',
  workflows: {
    formGeneration: formGenerationWorkflow,
    contractAnalysis: contractAnalysisWorkflow
  }
});

Testing MCP Connection:

$mastra-dev mcp test --server "wikipedia"
# Output: ✅ Connected to wikipedia MCP server
#         Available tools: search_wikipedia, get_article, get_summary
#         Transport: stdio
#         Status: healthy

6. Analysis & Debugging

Analyze Mastra setup, debug workflow execution, and validate configurations.

Commands:

  ⏸️ Step 4: assess-risks
     Status: SKIPPED (previous step failed)

🔍 ROOT CAUSE:
  Step 'check-compliance' failed due to undefined property access.

  Likely issue: Missing FAR compliance database connection or
  incorrect data structure returned from identify-clauses step.

💡 SUGGESTED FIX:
  1. Verify far-compliance tool is properly configured
  2. Check inputData schema in check-compliance step
  3. Add null checking: if (!inputData.clauses) throw new Error(...)
  4. Review step schema compatibility

Auto-Registration

When you create agents, workflows, or tools, the skill automatically:

Generates TypeScript files in the correct directories
Updates mastra.config.ts to register new constructs
Updates mcp.config.ts to expose workflows as MCP tools
Validates TypeScript syntax before writing
Preserves existing code (no destructive edits)

Example Registration Update:

Before:

// apps/mastra/src/config/mastra.config.ts
export const mastra = new Mastra({
  storage,
  agents: {},
  workflows: {},
  tools: {}
});

After running $mastra-dev create-agent --name "proposal-writer":

import { proposalWriterAgent } from '../agents/proposal-writer.js';

export const mastra = new Mastra({
  storage,
  agents: {
    proposalWriter: proposalWriterAgent  // ← Auto-added
  },
  workflows: {},
  tools: {}
});

Development Workflow

Start Mastra server (if not running):
```
$mastra-dev server start
```

Create constructs as needed:

$mastra-dev create-agent --name "my-agent"
$mastra-dev create-workflow --name "my-workflow"
$mastra-dev create-tool --name "my-tool"

Edit generated files to implement logic:
- Agents: Add custom instructions and tool configurations
- Workflows: Implement step execute functions
- Tools: Add business logic to execute functions

Test locally:

$mastra-dev test-workflow --name "my-workflow" --input '{...}'
$mastra-dev test-tool --name "my-tool" --input '{...}'

Use Mastra Studio for visual debugging:

$mastra-dev studio start
# Open http://localhost:4111

Validate before commit:
```
$mastra-dev validate
```

Best Practices

1. Agent Development

✅ DO:

Use clear, specific instructions
Choose appropriate models for tasks (Opus for complex reasoning, Sonnet for speed)
Register only necessary tools (avoid tool overload)
Test agents with agent.generate() before production use
Use memory systems for conversation context

❌ DON'T:

Use generic instructions like "You are a helpful assistant"
Register all available tools (increases latency and confusion)
Skip testing agent behavior
Hardcode API keys or secrets in agent definitions

2. Workflow Design

✅ DO:

Define clear input/output schemas for every step
Use .parallel() for independent operations
Implement retry policies for unstable external APIs
Add error handling with lifecycle callbacks
Validate schema compatibility between steps
Use .commit() to finalize workflow definitions

❌ DON'T:

Create circular dependencies (DAG must be acyclic)
Skip schema definitions (causes runtime errors)
Use .branch() without proper conditionals
Forget to call .commit() at the end
Ignore step execution order requirements

3. Tool Development

✅ DO:

Write descriptive tool descriptions for agents
Use Zod for comprehensive input validation
Handle edge cases and errors gracefully
Return structured data matching output schema
Test tools independently before agent integration

❌ DON'T:

Use vague descriptions (agents won't know when to call)
Skip input validation (leads to runtime errors)
Return inconsistent output structures
Assume external APIs are always available
Expose sensitive operations without safeguards

4. MCP Integration

✅ DO:

Use stdio transport for local MCP servers
Use HTTP transport for remote MCP servers
Test MCP connections with $mastra-dev mcp test
Document which agents use which MCP tools
Version MCP server configurations

❌ DON'T:

Mix stdio and HTTP incorrectly
Skip connection testing
Hardcode URLs in MCP config
Forget to restart server after MCP changes

5. Testing & Debugging

✅ DO:

Test workflows with representative data
Use Mastra Studio for visual debugging
Check logs regularly during development
Validate configurations before committing
Debug failed executions with execution IDs

❌ DON'T:

Skip testing with real data
Ignore workflow execution failures
Deploy without validating configurations
Debug in production (use staging/dev environments)

Troubleshooting

Issue 1: "Mastra server is not running"

Symptoms:

❌ Mastra server is not running (port 6000)

Solutions:

# Start the server
$mastra-dev server start

# Test the workflow
$mastra-dev test-workflow \
  --name "form-generation" \
  --input '{"opportunityId": "abc-123"}'

Generated File: apps/mastra/src/workflows/form-generation.ts

import { createWorkflow, createStep } from '@mastra/core/workflows';
import { z } from 'zod';

const fetchOpportunityStep = createStep({
  id: 'fetch-opportunity',
  inputSchema: z.object({ opportunityId: z.string() }),
  outputSchema: z.object({ opportunity: z.any() }),
  execute: async ({ inputData }) => {
    // API call implementation
    const response = await fetch(`https://api.sam.gov/opportunities/${inputData.opportunityId}`);
    return { opportunity: await response.json() };
  }
});

const extractDataStep = createStep({
  id: 'extract-data',
  inputSchema: z.object({ opportunity: z.any() }),
  outputSchema: z.object({ formData: z.any() }),
  execute: async ({ inputData }) => {
    // Transform logic
    return { formData: { /* extracted data */ } };
  }
});

const generatePdfStep = createStep({
  id: 'generate-pdf',
  inputSchema: z.object({ formData: z.any() }),
  outputSchema: z.object({ pdfUrl: z.string() }),
  execute: async ({ inputData }) => {
    // PDF generation
    return { pdfUrl: 'https://example.com/form.pdf' };
  }
});

export const formGenerationWorkflow = createWorkflow({
  id: 'form-generation',
  description: 'Auto-fill government forms from SAM.gov data',
  inputSchema: z.object({ opportunityId: z.string() }),
  outputSchema: z.object({ formData: z.any(), pdfUrl: z.string() })
})
  .then(fetchOpportunityStep)
  .then(extractDataStep)
  .then(generatePdfStep)
  .commit();

Control Flow Patterns:

Sequential: .then(stepA).then(stepB).then(stepC)
Parallel: .parallel([stepA, stepB, stepC])
Conditional: .branch({ when: (data) => data.score > 0.8, then: highPath, otherwise: lowPath })

3. Tool Management

Create reusable tools with schema validation and type safety.

  [--output-schema <json-schema>]

# List all tools
$mastra-dev list-tools

# Test tool execution
$mastra-dev test-tool \
  --name <tool-name> \
  --input <json-input>

Example - Create PDF Generator Tool:

$mastra-dev create-tool \
  --name "pdf-generator" \
  --description "Generate PDF from template and data" \
  --input-schema '{"template": "string", "data": "object"}' \
  --output-schema '{"pdfUrl": "string", "size": "number"}'

export const pdfGeneratorTool = createTool({
  id: 'pdf-generator',
  description: 'Generate PDF from template and data',
  inputSchema: z.object({
    template: z.string(),
    data: z.record(z.any())
  }),
  outputSchema: z.object({
    pdfUrl: z.string(),
    size: z.number()
  }),
  execute: async ({ inputData }) => {
    // PDF generation logic
    const pdfUrl = await generatePdf(inputData.template, inputData.data);
    return {
      pdfUrl,
      size: 12345
    };
  }
});

5. MCP Management

Configure Model Context Protocol integration for external tool access.

Commands:

# Add MCPClient for consuming external servers
$mastra-dev mcp add-client \
  --name <server-name> \
  --command <command> \
  [--args <comma-separated-args>] \
  [--url <http-url>]

# Configure MCPServer to expose Mastra tools
$mastra-dev mcp configure-server \
  [--agents <comma-separated-agent-ids>] \
  [--workflows <comma-separated-workflow-ids>] \
  [--tools <comma-separated-tool-ids>]

# List all MCP servers
$mastra-dev mcp list-servers

# Test MCP server connection
$mastra-dev mcp test --server <server-name>

Example - Add External MCP Servers:

# Add local stdio MCP server (Wikipedia)
$mastra-dev mcp add-client \
  --name "wikipedia" \
  --command "npx" \
  --args "-y,wikipedia-mcp"

# Add remote HTTP MCP server (Weather)
$mastra-dev mcp add-client \
  --name "weather" \
  --url "https://server.smithery.ai/@smithery-ai/national-weather-service/mcp"

# Add Puppeteer for browser automation
$mastra-dev mcp add-client \
  --name "puppeteer" \
  --command "npx" \
  --args "-y,@modelcontextprotocol/server-puppeteer"

Updated Configuration: apps/mastra/src/config/mcp.config.ts

import { MCPClient } from '@mastra/mcp';

export const mcpClient = new MCPClient({
  id: 'mastra-mcp-client',
  servers: {
    wikipedia: {
      command: 'npx',
      args: ['-y', 'wikipedia-mcp']
    },
    weather: {
      url: new URL('https://server.smithery.ai/@smithery-ai/national-weather-service/mcp')
    },
    puppeteer: {
      command: 'npx',
      args: ['-y', '@modelcontextprotocol/server-puppeteer']
    }
  }
});

Example - Expose Mastra Workflows via MCP:

# Configure MCPServer to expose workflows
$mastra-dev mcp configure-server \
  --workflows "form-generation,contract-analysis"

Updated Configuration:

import { MCPServer } from '@mastra/mcp';
import { formGenerationWorkflow } from '../workflows/form-generation.js';
import { contractAnalysisWorkflow } from '../workflows/contract-analysis.js';

export const mastraMcpServer = new MCPServer({
  id: 'mastra-workflows',
  name: 'Mastra Workflow Engine',
  version: '1.0.0',
  workflows: {
    formGeneration: formGenerationWorkflow,
    contractAnalysis: contractAnalysisWorkflow
  }
});

Testing MCP Connection:

$mastra-dev mcp test --server "wikipedia"
# Output: ✅ Connected to wikipedia MCP server
#         Available tools: search_wikipedia, get_article, get_summary
#         Transport: stdio
#         Status: healthy

Integration with Mastra App

This skill integrates seamlessly with the existing Mastra app at /home/artsmc/applications/low-code/apps/mastra:

Directory Structure

apps/mastra/
├── src/
│   ├── agents/                  # ← Generated agent files

└── package.json

Auto-Registration

When you create agents, workflows, or tools, the skill automatically:

Generates TypeScript files in the correct directories
Updates mastra.config.ts to register new constructs
Updates mcp.config.ts to expose workflows as MCP tools
Validates TypeScript syntax before writing
Preserves existing code (no destructive edits)

Example Registration Update:

Before:

// apps/mastra/src/config/mastra.config.ts
export const mastra = new Mastra({
  storage,
  agents: {},
  workflows: {},
  tools: {}
});

After running $mastra-dev create-agent --name "proposal-writer":

import { proposalWriterAgent } from '../agents/proposal-writer.js';

export const mastra = new Mastra({
  storage,
  agents: {
    proposalWriter: proposalWriterAgent  // ← Auto-added
  },
  workflows: {},
  tools: {}
});

Development Workflow

Start Mastra server (if not running):
```
$mastra-dev server start
```

Create constructs as needed:

$mastra-dev create-agent --name "my-agent"
$mastra-dev create-workflow --name "my-workflow"
$mastra-dev create-tool --name "my-tool"

Edit generated files to implement logic:
- Agents: Add custom instructions and tool configurations
- Workflows: Implement step execute functions
- Tools: Add business logic to execute functions

Test locally:

$mastra-dev test-workflow --name "my-workflow" --input '{...}'
$mastra-dev test-tool --name "my-tool" --input '{...}'

Use Mastra Studio for visual debugging:

$mastra-dev studio start
# Open http://localhost:4111

Validate before commit:
```
$mastra-dev validate
```

Best Practices

1. Agent Development

✅ DO:

Use clear, specific instructions
Choose appropriate models for tasks (Opus for complex reasoning, Sonnet for speed)
Register only necessary tools (avoid tool overload)
Test agents with agent.generate() before production use
Use memory systems for conversation context

❌ DON'T:

Use generic instructions like "You are a helpful assistant"
Register all available tools (increases latency and confusion)
Skip testing agent behavior
Hardcode API keys or secrets in agent definitions

2. Workflow Design

✅ DO:

Define clear input/output schemas for every step
Use .parallel() for independent operations
Implement retry policies for unstable external APIs
Add error handling with lifecycle callbacks
Validate schema compatibility between steps
Use .commit() to finalize workflow definitions

❌ DON'T:

Create circular dependencies (DAG must be acyclic)
Skip schema definitions (causes runtime errors)
Use .branch() without proper conditionals
Forget to call .commit() at the end
Ignore step execution order requirements

3. Tool Development

✅ DO:

Write descriptive tool descriptions for agents
Use Zod for comprehensive input validation
Handle edge cases and errors gracefully
Return structured data matching output schema
Test tools independently before agent integration

❌ DON'T:

Use vague descriptions (agents won't know when to call)
Skip input validation (leads to runtime errors)
Return inconsistent output structures
Assume external APIs are always available
Expose sensitive operations without safeguards

4. MCP Integration

✅ DO:

Use stdio transport for local MCP servers
Use HTTP transport for remote MCP servers
Test MCP connections with $mastra-dev mcp test
Document which agents use which MCP tools
Version MCP server configurations

❌ DON'T:

Mix stdio and HTTP incorrectly
Skip connection testing
Hardcode URLs in MCP config
Forget to restart server after MCP changes

5. Testing & Debugging

✅ DO:

Test workflows with representative data
Use Mastra Studio for visual debugging
Check logs regularly during development
Validate configurations before committing
Debug failed executions with execution IDs

❌ DON'T:

Skip testing with real data
Ignore workflow execution failures
Deploy without validating configurations
Debug in production (use staging/dev environments)

Troubleshooting

Issue 1: "Mastra server is not running"

Symptoms:

❌ Mastra server is not running (port 6000)

Solutions:

# Start the server
$mastra-dev server start

# If that fails, check if port is in use
lsof -i :6000

# Kill existing process if needed
kill -9 <PID>

# Start again
$mastra-dev server start

Issue 2: "Agent not found in mastra.config.ts"

Symptoms:

⚠️ Agent 'my-agent' exists but not registered in mastra.config.ts

Solutions:

# Re-run create-agent with --force flag (if implemented)
$mastra-dev create-agent --name "my-agent" --force

# Or manually add to mastra.config.ts:
# 1. Import: import { myAgent } from '../agents/my-agent.js';
# 2. Register: agents: { myAgent }

Issue 3: "Workflow execution failed with schema error"

Symptoms:

❌ Step 'fetch-data' failed: Input validation error
Expected { userId: string }, got { user_id: string }

Solutions:

Verify step schemas match data flow
Check previous step's output schema
Update input schema to match actual data structure
Use schema transformation step if needed

# Debug the workflow
