Pull request overview

This PR replaces multiple explicit any usages with stronger TypeScript typings across workflow and service modules, aiming to improve type-safety for workflow YAML parsing/execution, agent integration, collaboration events, chat persistence, and RAG web results.

Changes:

Added structured interfaces/type guards for workflow YAML parsing and validation.
Introduced typed Agent API integration contracts and workflow monitoring event structures.
Tightened typings in collaboration, chat MongoDB, RAG, and unified AI client proxy access.

src/lib/workflow/integration.ts

  // await databaseClient.insertWorkflowExecution(record);
-  console.log('Workflow execution saved:', record.id);
+  console.log("Workflow execution saved:", record.id);
+}


This module introduces console.log for workflow execution persistence. In this repo we generally use the structured logger (see src/lib/logger.ts) rather than console output so logs are correctly routed/structured in production. Replace this with the project logger (or remove logging if this is purely a placeholder).

src/lib/workflow/parser.ts

 export async function parseWorkflowYAML(yamlContent: string): Promise<WorkflowDefinition> {
-  let parsed: any;
+  let parsed: ParsedYAMLWorkflow;

  try {
    // Dynamic import for YAML parsing (Next.js compatible)
-    const yaml = await import('js-yaml');
-    parsed = yaml.load(yamlContent);
+    const yaml = await import("js-yaml");
+    parsed = yaml.load(yamlContent) as ParsedYAMLWorkflow;
  } catch (error) {
-    throw new Error(`Failed to parse YAML: ${error instanceof Error ? error.message : 'Unknown error'}`);
+    throw new Error(`Failed to parse YAML: ${error instanceof Error ? error.message : "Unknown error"}`);
  }

  // Validate required fields
  if (!parsed.name) {
-    throw new Error('Workflow must have a name');
+    throw new Error("Workflow must have a name");
  }

  if (!parsed.version) {
-    throw new Error('Workflow must have a version');
+    throw new Error("Workflow must have a version");
  }

  if (!parsed.nodes || !Array.isArray(parsed.nodes)) {
-    throw new Error('Workflow must have nodes array');
+    throw new Error("Workflow must have nodes array");
  }


parseWorkflowYAML casts yaml.load(...) directly to ParsedYAMLWorkflow. If js-yaml returns undefined/null/a scalar for invalid or empty YAML, subsequent property access (parsed.name, parsed.nodes, etc.) will throw at runtime. Add a runtime check after load to ensure the parsed value is a non-null object before continuing, and throw a user-friendly parse/validation error otherwise.

src/lib/workflow/parser.ts

+            errors.push(`Node ${node.id}: webhook requires method`);
+          }
        }
        break;


validateWorkflowDefinition doesn't report unsupported/unknown node.type values (it just falls through). Since YAML parsing uses type assertions, invalid node types can slip through and only fail later during execution. Add a default case that records an error for unknown node types (and optionally validate node.type against the known NodeType set during parsing).

Suggested change

default:

if (!node.type) {

errors.push(`Node ${node.id}: node type is required`);

} else {

errors.push(`Node ${node.id}: unsupported node type "${node.type}"`);

}

src/lib/services/collaboration.ts

+    const socketsMap = this.io?.sockets.sockets;
+    // Engine startTime is not in the public API, use a fallback
+    const uptime = this.io ? Date.now() : 0;

    return {
      isHealthy: this.io !== null,
-      activeConnections: sockets?.size ?? 0,
+      activeConnections: socketsMap?.size ?? 0,
      activeSessions: this.sessions.size,
      uptime
    };


uptime is currently set to Date.now(), which returns an epoch timestamp rather than an uptime duration. This makes the health metric incorrect/meaningless. Track a service start timestamp (e.g., when initialize() is called) and return Date.now() - startedAt (or use process.uptime() converted to ms).

src/lib/workflow/integration.ts

+/** Agent status response from API */
+interface AgentStatusResponse {
+  agent_id: string;
+  status: AgentStatus;
+  last_output?: string;
+  exit_code?: number;
+  error?: string;
+}
+
+/** Message response from agent */
+interface AgentMessageResponse {
+  success: boolean;
+  message_id?: string;
+  response?: string;
+}
+
+/** Stop agent response */
+interface StopAgentResponse {
+  success: boolean;
+  agent_id: string;
+  final_status: AgentStatus;
+}


The local AgentStatusResponse/AgentMessageResponse/StopAgentResponse interfaces don't match the canonical response types in src/types/agent-api.ts (e.g., StopAgentResponse shape, exit_code is number | null, SendMessageResponse shape). This makes it hard/impossible for a real Agent API client to satisfy AgentAPIClient. Prefer importing and using the exported AgentStatusResponse, SendMessageResponse, and StopAgentResponse types instead of redefining them.

src/lib/workflow/integration.ts

    const request: StartAgentRequest = {
-      agent_type: config.agentType as 'aider' | 'goose' | 'cline',
-      model: config.model as any,
+      agent_type: config.agentType as "aider" | "goose" | "cline",
+      model: config.model as ModelType,
      task: config.task,
-      workspace: config.workspace || '/home/coder/workspace',
+      workspace: config.workspace || "/home/coder/workspace",
      files: config.files,


AgentTaskConfig.agentType allows 'continue' (src/lib/workflow/types.ts:138), but the request here narrows to only "aider" | "goose" | "cline" via a type assertion. If a workflow provides agentType: "continue", this will be sent to the Agent API even though it is not a supported AgentType (src/types/agent-api.ts:15), likely causing runtime failures. Add an explicit mapping/validation step and throw a clear error for unsupported values.
