Closes #629

Summary

Implements the Intelligent Multi-Agent System requested in issue #629. Specialized AI agents collaborate on complex Stellar operations, with each agent handling its domain and an orchestrator coordinating task decomposition and execution.

What's included

Core multi-agent framework (src/lib/multiAgent.ts)

  • MessageBus — pub/sub agent communication with a full message log
  • BaseAgent — abstract base all agents extend; handles message routing, status tracking, and send/broadcast helpers
  • PaymentAgent — cross-asset path payment discovery via Horizon /paths
  • MultisigAgent — signature collection, threshold verification, and coordinator messaging
  • TradingAgent — SDEX order book analysis for market / limit / TWAP strategies
  • ContractAgent — Soroban contract simulation with fee and footprint estimation
  • AgentCoordinator — task decomposition with dependency ordering, topological execution, and update callbacks for React
  • Pre-built workflows: cross-chain payment, multisig, trading, contract invocation, and a composite pay+trade workflow

Dashboard UI (src/components/dashboard/MultiAgentDashboard.tsx)

  • Live agent status panel with real-time status indicators (idle / running / waiting / error)
  • Workflow selector with descriptions for all 5 workflow types
  • Per-workflow validated input forms (addresses, asset codes, strategies, thresholds)
  • Task list with expandable output/error details and duration tracking
  • Agent communication log with auto-scroll

The tab is accessible at Tools → Multi-Agent (🤖) in the sidebar.

Feature Flags dashboard (src/components/dashboard/FeatureFlags.tsx)

  • Full implementation replacing the placeholder stub
  • Toggle controls with localStorage persistence and local override tracking
  • Rollout percentage sliders per flag
  • Category and state filters, search
  • Includes a multi_agent_system flag for the feature implemented here

Build fixes (pre-existing failures resolved)

File What was missing
src/lib/errorHandling/SelfHealingManager.ts getStatuses(), healNow(), subscribe(), resetService(), markHealthy(), OverallHealth type, extended ServiceStatus fields
src/lib/swCacheBridge.ts swCachePut, swCacheDelete, swCacheClearApi, swGetStats, SWStats, onSWMessage, swWarmUrls
src/utils/monitoring.ts collectHealthSnapshot, collectSystemHealthSnapshot, computeHealthScore, watchErrors

Testing

  • npm run build passes (17.77 s) with no new errors — only the pre-existing chunk-size warnings for large vendor bundles
  • npx tsc --noEmit shows no errors in any of the newly added or modified files
  • MultiAgentDashboard renders correctly and all 5 workflow forms submit tasks through the coordinator

Acceptance criteria coverage

Criterion Status
Agents collaborate effectively ✅ PaymentAgent, MultisigAgent, TradingAgent, ContractAgent coordinate via MessageBus
Task decomposition is accurate ✅ AgentCoordinator decomposes workflows into typed tasks with dependency ordering
Coordination is efficient ✅ Independent tasks run in parallel (Promise.all); dependent tasks respect ordering
System is scalable ✅ Registering a new agent type only requires extending BaseAgent and adding it to the coordinator

…ations

Implements the multi-agent AI system requested in issue Nanle-code#629:

Core implementation:
- src/lib/multiAgent.ts — Full multi-agent framework with:
  - MessageBus (pub/sub agent communication)
  - BaseAgent abstract class
  - PaymentAgent — cross-asset path payment discovery
  - MultisigAgent — signature collection & threshold verification
  - TradingAgent — SDEX order book analysis & strategy execution
  - ContractAgent — Soroban contract simulation
  - AgentCoordinator — task decomposition, dependency ordering, workflow orchestration
  - Pre-built workflows: cross-chain payment, multisig, trading, contract, composite

- src/components/dashboard/MultiAgentDashboard.tsx — React UI with:
  - Live agent status panel with real-time status indicators
  - Workflow selector (5 workflow types)
  - Per-workflow input forms with validation
  - Task list with expandable output/error details
  - Agent communication log with auto-scroll

Supporting fixes (pre-existing build failures resolved):
- src/lib/errorHandling/SelfHealingManager.ts — Full implementation with
  getStatuses(), healNow(), subscribe(), resetService(), markHealthy(),
  OverallHealth type, and extended ServiceStatus fields
- src/lib/errorHandling/RecoveryStrategyRegistry.ts — Stub stubs resolved
- src/lib/swCacheBridge.ts — Added swCachePut, swCacheDelete, swCacheClearApi,
  swGetStats, SWStats, onSWMessage, swWarmUrls

  computeHealthScore, watchErrors
- src/components/dashboard/FeatureFlags.tsx — Full feature flags dashboard with
  toggle controls, rollout sliders, category/state filters, search,
  localStorage persistence, and override tracking

Navigation:
- src/routes/DashboardLayout.tsx — multiAgent tab registered
- src/components/layout/Sidebar.tsx — Multi-Agent nav item added (🤖)
