Tab Management

AutoSteer provides robust tab management with per-project isolation. See docs/tab-management.md for detailed documentation.

Key Features:

• Per-project tab isolation: Only tabs for the selected project are visible
• Auto-select behavior: Automatically switches to another tab when closing
• Persistent state: Tab selection survives application restarts
• System tabs: Terminal and Changes tabs always present
• Maximize tabs: Dynamic tabs for maximize view

Configuration:

{
  "settings": {
    "confirmSessionTabDeletion": true
  }
}

🔍 Trace File Format

AutoSteer creates trace files for debugging SDK message flow. These files are stored in ~/.autosteer/traces/ and use JSONL format (one JSON object per line).

Trace File Location

~/.autosteer/traces/{sessionId}.trace.jsonl

Trace Entry Format

Each trace entry is a JSON object with the following structure:

{
  "timestamp": "2025-11-09T18:51:35.123Z",    // ISO 8601 timestamp
  "sessionId": "session-abc123",              // Session identifier
  "direction": "to-claude" | "from-claude",   // Message direction
  "rawMessage": { /* SDK message object */ }, // Complete SDK message
  "sdkVersion": "^0.1.0",                     // SDK version
  "correlationId": "550e8400-e29b-41d4",      // Request/response correlation
  "sequenceNumber": 42                         // Monotonic sequence per session
}

Trace File Lifecycle

• Creation: Trace files are created automatically when SDK messages are logged
• Rotation: Files are rotated when they exceed 100MB, with timestamp suffixes
• Cleanup: Trace files are automatically deleted when their project is deleted
• Manual Cleanup: Delete files in ~/.autosteer/traces/ to free disk space

Using Trace Files

Trace files are useful for:

• Debugging: Inspect exact SDK messages sent and received
• Performance Analysis: Track message timing and sequence
• Error Investigation: Review message flow leading to errors
• SDK Updates: Verify message format changes across SDK versions

Example Trace Entry

{
  "timestamp": "2025-11-09T18:51:35.123Z",
  "sessionId": "session-abc123",
  "direction": "from-claude",
  "rawMessage": {
    "type": "assistant",
    "uuid": "550e8400-e29b-41d4-a716-446655440000",
    "session_id": "session-abc123",
    "message": {
      "role": "assistant",
      "content": [{ "type": "text", "text": "Hello!" }]
    }
  },
  "sdkVersion": "^0.1.0",
  "correlationId": "550e8400-e29b-41d4",
  "sequenceNumber": 42,
  "messageType": "assistant",
  "messageSubtype": null
}

🔄 SDK Migration Guide

Overview

This guide helps developers handle Anthropic Claude SDK updates and Pydantic model changes without breaking existing message validation.

SDK Version Updates

When updating @anthropic-ai/claude-agent-sdk:

1. Check for Breaking Changes

   • Review SDK release notes for breaking changes
   • Test validation with new SDK types
   • Update Pydantic models if needed

2. Update Zod Schemas

   • Location: src/services/MessageValidator.ts
   • Match schemas to new SDK types
   • Maintain backward compatibility with relaxed validation

3. Test Validation

   pnpm test:unit -- MessageValidator.test.ts
   

4. Update Trace Documentation

   • Document new message types in README

Pydantic Model Changes

Adding New Message Types

1. Update Python Models

   • Follow existing BaseModel pattern
   • Add to SDKMessage union type

2. Update TypeScript Schemas

   • Add corresponding Zod schema in MessageValidator.ts
   • Add to discriminated union
   • Update type guards

3. Add Tests

   • Add test cases for new message type
   • Test strict and relaxed validation
   • Test partial extraction

Example:

// Add to MessageValidator.ts
const NewMessageTypeSchema = z.object({
  type: z.literal('new_type'),
  uuid: z.string().uuid(),
  session_id: z.string(),
  // ... other fields
});

Handling Breaking SDK Changes

If an SDK update breaks validation:

1. Identify Breaking Change

   • Check validation test failures
   • Review trace logs for error patterns
   • Compare old vs new message structure

2. Update Schemas Gradually

   // Old field (deprecated but still supported)
   old_field: z.string().optional(),
   
   // New field (preferred)
   new_field: z.string().optional(),
   

3. Add Migration Logic

   • Handle both old and new formats
   • Log warnings for deprecated fields
   • Gradually phase out old format

4. Version Compatibility

   • Track SDK version in trace logs
   • Add version checks if needed
   • Document version requirements

Testing Migration

# Run all validation tests
pnpm test:unit -- MessageValidator

# Test with fixtures
pnpm test:integration -- message-validation

# Check type coverage
pnpm typecheck

Rollback Strategy

If validation breaks in production:

1. Immediate: Revert to previous SDK version
2. Short-term: Deploy hotfix with relaxed validation
3. Long-term: Fix schemas and redeploy

Best Practices

• Always test with real message fixtures before deploying
• Maintain backward compatibility for at least 2 SDK versions
• Document breaking changes in PR descriptions
• Use relaxed validation as fallback to prevent crashes
• Monitor trace logs for validation failures after updates

🔒 Security

1. Process Isolation: Agents run in separate processes
2. Local Storage: All data stays on your machine
3. No Telemetry: No data collection or tracking
