Instead of hierarchical navigation:

// ❌ OLD WAY (4+ API calls)
clickup_get_workspaces() → clickup_get_spaces() → clickup_get_views() → filter for chat

// ✅ NEW WAY (1 API call)
clickup_find_chat_channels({ channel_name: "development" })

clickup_analyze_workflow_efficiency({
  goal: "Post message to team chat",
  planned_tools: ["clickup_get_workspaces", "clickup_get_spaces", "clickup_get_views"],
  time_constraint: "urgent"
})
// Returns: Optimized workflow with 55% efficiency gain

// Process ClickUp webhooks with HMAC validation
clickup_process_webhook({
  payload: webhookData,
  validate_signature: true,
  signature: request.headers['x-signature'],
  secret: process.env.WEBHOOK_SECRET
})
// Returns: Structured event data with relationships and changes
