Handover: 2026-03-10 - Agent Workflows E2E Implementation Complete

Branch: main Upstream: ab685db4 (6 commits ahead of previous) Previous Handover: 2026-03-03 - Phase A+B Implementation Complete

1. Progress Summary

Tasks Completed This Session

  1. Phase 3 Implementation Complete - Agent Workflows End-to-End Demonstration

    • Created shared/workflow-types.js with type definitions for all workflow patterns
    • Updated shared/api-client.js with real API integration for all 5 workflow endpoints
    • Updated shared/websocket-client.js with unsubscribe capability
    • Updated all 5 workflow examples to call real backend APIs instead of mock data
    • Integrated WebSocket real-time updates across all examples
    • Replaced all emoji with FontAwesome icons per CLAUDE.md guidelines

  2. Examples Updated

    • 1-prompt-chaining/ - WebSocket integration, real API calls
    • 2-routing/ - WebSocket integration, real API calls
    • 3-parallelization/ - WebSocket integration, real API calls, FontAwesome icons
    • 4-orchestrator-workers/ - WebSocket integration, real API calls, FontAwesome icons
    • 5-evaluator-optimizer/ - WebSocket integration, real API calls

  3. Testing Complete

    • Verified all examples load correctly in browser
    • Confirmed API integration works for routing, parallel, and orchestrate workflows
    • Validated WebSocket connections receive workflow updates
    • Screenshots captured for visual verification

  4. Commits Pushed to upstream/main

    • c05452f5 feat(agent-workflows): Day 1 foundation - workflow types, API client, WebSocket
    • 440d5902 feat(agent-workflows): update prompt chaining example for real API integration
    • 573c099d feat(agent-workflows): update examples 2-5 for real API integration
    • 09a3d61b chore(build): update Cargo.toml and Cargo.lock

Current Implementation State

Working:

  • All 5 workflow examples integrate with real backend APIs
  • WebSocket subscriptions provide real-time workflow status updates
  • FontAwesome icons display correctly in all examples
  • API endpoints tested:
    • POST /workflows/routing - Working
    • POST /workflows/parallel - Working
    • POST /workflows/orchestration - Working
    • POST /workflows/prompt_chain - Working (with valid role)
    • POST /workflows/optimization - Working (with valid role)

Fixed:

  • All missing roles added to terraphim_server/default/terraphim_engineer_config.json:
    • BusinessAnalyst - requirements analysis
    • QAEngineer - quality assurance and testing
    • BackendArchitect - system architecture design
    • ProductManager - development planning
    • DevelopmentAgent - code implementation
    • DevOpsEngineer - deployment and operations

3. Next Steps

Priority 1: Verification Testing (Completed)

  • ✅ All 5 workflow endpoints tested successfully with new roles:
    • POST /workflows/prompt-chain with BusinessAnalyst - Working
    • POST /workflows/route with BusinessAnalyst - Working
    • POST /workflows/parallel with QAEngineer - Working
    • POST /workflows/orchestrate with DevelopmentAgent - Working
    • POST /workflows/optimize with BusinessAnalyst - Working

Priority 2: Run Full Test Suite

  • Run: cargo test --workspace --exclude terraphim_agent
  • Test examples in browser with server running
  • Verify WebSocket message handling under load

Priority 3: Documentation

  • Create RUNNING_E2E.md with instructions for running the complete demo
  • Document the workflow API contract for future reference
  • Update example READMEs with real API integration details

4. Key Implementation Details

API Client Usage Pattern

// Initialize API client with server discovery
const apiClient = new ApiClient();
await apiClient.init();

// Execute workflow
const result = await apiClient.executeRouting({
  prompt: "user input",
  role: "Terraphim Engineer",
  llm_config: { ... }
});

// Subscribe to updates
const wsClient = new WorkflowWebSocketClient(apiClient.serverUrl);
await wsClient.connect();
wsClient.subscribeToWorkflow(result.workflow_id, handleMessage);

WebSocket Message Format

{
  type: 'workflow_update',
  workflow_id: 'uuid',
  status: 'running|completed|failed',
  data: { ... },
  timestamp: 'ISO8601'
}

FontAwesome Icon Mapping

  • Workflow patterns: fa-link, fa-route, fa-code-branch, fa-network-wired, fa-sync-alt
  • Status: fa-clock, fa-spinner fa-spin, fa-check-circle, fa-times-circle
  • UI elements: fa-bolt, fa-bullseye, fa-robot, fa-brain, fa-puzzle-piece, fa-chart-line
