Workflow-Driven Execution + +Every request is processed by a **workflow**β€”a JSON file that defines execution steps. Workflows are: +- **Declarative**: Define what to do, not how +- **Composable**: Steps can call other workflows +- **Configurable**: Store in `workflows/` or custom directory + +```json +{ + "id": "fast-router", + "title": "Fast Router", + "steps": [ + { + "name": "route", + "action": { + "type": "llm", + "prompt": "@input.message", + "model": "fast", + "tools": "all" + } + } + ] +} +``` + +### 2. Event-Driven Communication + +Pilot never calls interfaces directly. It: +- **Subscribes** to `user.message.received` events +- **Publishes** `agent.response.*` events for each interface +- **Publishes** progress and completion events + +This decouples the agent from specific interfaces. + +### 3. MCP Tasks Protocol + +Pilot implements the [MCP Tasks specification](https://modelcontextprotocol.io/specification/draft/basic/utilities/tasks): +- Tasks are persisted to disk as JSON +- Status: `working`, `completed`, `failed`, `cancelled` +- Full execution trace for debugging + +## Components + +### Main Entry Point (`server/main.ts`) + +| Section | Purpose | +|---------|---------| +| Configuration | Parse env vars, validate workflows | +| Bindings | LLM, CONNECTION, EVENT_BUS from mesh | +| Mesh API | `callMeshTool`, `callLLM`, `publishEvent` | +| Workflow Execution | `startWorkflow`, `handleConversationMessage` | +| MCP Tools | All registered tools | + +### Workflow Executor (`server/core/workflow-executor.ts`) + +The engine that runs workflows step-by-step: + +```typescript +await executeWorkflow("fast-router", { + message: "Hello", + history: [] +}, { + callLLM, // LLM callback + callMeshTool, // Tool execution + listConnections, // Discover tools + publishEvent, // Progress updates +}); +``` + +**Step Types:** +- `llm`: Call LLM with prompt, tools, system prompt +- `tool`: Call a specific MCP tool +- `code`: Run TypeScript transform (future) + +### Task Storage (`server/core/task-storage.ts`) + +Persists tasks to `TASKS_DIR` as JSON files: + +```typescript +interface Task { + taskId: string; + status: "working" | "completed" | "failed" | "cancelled"; + workflowId: string; + workflowInput: Record; + stepResults: StepResult[]; + result?: unknown; + error?: string; + createdAt: string; + lastUpdatedAt: string; +} +``` + +### Conversation Manager (`server/core/conversation-manager.ts`) + +Manages long-running conversation threads: +- Tracks active conversations by `source + chatId` +- Routes follow-up messages to same conversation +- Auto-expires after timeout + +## Event Flow + +### Request β†’ Response + +``` +1. Interface sends message (e.g., WhatsApp via Bridge) + ↓ +2. Bridge publishes to Event Bus + EVENT_PUBLISH("user.message.received", { text, source: "whatsapp", chatId }) + ↓ +3. Pilot receives via ON_EVENTS tool + ↓ +4. Pilot routes to workflow (fast-router by default) + ↓ +5. Workflow executes: + a. LLM analyzes request + b. LLM calls tools if needed (via mesh) + c. LLM generates response + ↓ +6. Pilot publishes response event + EVENT_PUBLISH("agent.response.whatsapp", { text, taskId, isFinal: true }) + ↓ +7. Bridge receives via ON_EVENTS + ↓ +8. Bridge sends to extension β†’ appears in WhatsApp +``` + +### Progress Updates + +During execution, Pilot publishes progress events: + +```typescript +await publishEvent("agent.task.progress", { + taskId: "task-123", + source: "whatsapp", + chatId: "self", + message: "πŸ” Searching the web..." +}); +``` + +Interfaces can display these to users. + +## Event Types + +### Subscribed (Incoming) + +```typescript +"user.message.received" { + text: string; // Message content + source: string; // Interface (whatsapp, cli, etc.) + chatId?: string; // Conversation ID + sender?: { name?: string }; + metadata?: Record; +} +``` + +### Published (Outgoing) + +```typescript +"agent.response.{source}" { + taskId: string; + chatId?: string; + text: string;
