[Kylejeong2]

what

Mastra integration was not working due to us being on a really old version of the package. this PR updates relevant packages in the Mastra integration as well as adds the navigation tool to the agent.

📋 Code Review Summary

This PR successfully updates the Mastra integration with significant dependency upgrades and architectural improvements. The changes address compatibility issues while adding useful navigation functionality.

🔍 Detailed Analysis

Package Updates (package.json)

✅ Good: Major version upgrades across all Mastra packages:

• @browserbasehq/stagehand: ^2.4.4 → ^2.5.2
• @mastra/core: ^0.8.3 → ^0.20.2 (significant jump)
• mastra: ^0.4.9 → ^0.15.1 (significant jump)
• @mastra/memory: ^0.2.10 → ^0.15.6
• Added: @mastra/loggers ^0.10.15

Code Quality & Best Practices

✅ Strengths:

• Clean removal of unused memory implementation in agents/index.ts:4-5
• Proper logger migration from deprecated createLogger to PinoLogger in index.ts:2,7
• Addition of stagehandNavigateTool enhances functionality per PR description
• Consistent code style maintained throughout changes
• Good separation of concerns maintained

⚠️ Considerations:

• The memory removal might impact existing workflows if memory persistence was being used
• Large version jumps (0.8.3 → 0.20.2) could introduce breaking changes

Potential Issues

🔍 Memory Management:

// Removed from agents/index.ts:4-6
- import { Memory } from '@mastra/memory';
- const memory = new Memory();
- memory: memory

Impact: Any existing sessions relying on memory persistence will lose this functionality. Consider documenting this breaking change.

🔍 Logger Migration:

// Changed in mastra/index.ts:2,7
- import { createLogger } from '@mastra/core/logger';
+ import { PinoLogger } from '@mastra/loggers';
- logger: createLogger({
+ logger: new PinoLogger({

Status: ✅ This follows the new Mastra architecture pattern properly.

Security Assessment

✅ No security concerns identified:

• Environment variables properly referenced (BROWSERBASE_API_KEY, BROWSERBASE_PROJECT_ID)
• No hardcoded credentials or sensitive data
• Proper error handling maintains security boundaries
• Session management includes timeout cleanup to prevent resource leaks

Performance Considerations

✅ Performance Improvements:

• Updated Stagehand version likely includes performance optimizations
• Session cleanup mechanism prevents memory leaks (tools/index.ts:91-105)
• Singleton pattern for session management reduces overhead

⚠️ Monitor:

• Large dependency version jumps may affect bundle size
• New navigation tool adds functionality but also complexity

Test Coverage

⚠️ Testing Gaps:

• No test files visible in changed files
• No test script in package.json beyond placeholder
• Consider adding integration tests for:
  • Memory removal impact
  • New navigation tool functionality
  • Logger migration compatibility

Recommendations

1. Documentation: Update README/docs to reflect memory removal
2. Testing: Add integration tests for the new navigation functionality
3. Monitoring: Watch for any runtime issues from major version bumps
4. Gradual Rollout: Consider testing in staging before production deployment

✅ Overall Assessment

Approval Recommended - This is a solid maintenance PR that successfully modernizes the Mastra integration. The code quality is good, security practices are followed, and the changes align with the stated goals of fixing compatibility issues and adding navigation tools.

The major dependency updates are necessary for functionality, and the code changes properly adapt to the new APIs while maintaining clean architecture.
