With the tools activated (section 5), your agent can look up and write to HubSpot while chatting. Two real conversation examples: > **Note — Example — searching before creating** > > A customer writes over WhatsApp giving their email. The agent uses "Search contacts" to see whether a contact with that email already exists in HubSpot; if it doesn't, it uses "Create a new contact in the CRM" with the data it already has from the conversation — it never duplicates an existing contact. > **Note — Example — logging a deal** > > After confirming a customer's interest in a proposal, the agent uses "Search sales opportunities" and, if it applies, "Add a note in the CRM" with a summary of what was discussed — your sales team sees the note in HubSpot without having to copy it by hand. HubSpot doesn't have its own piece in the **flow builder** today (unlike pieces such as "Email (read-only)", Manual 61): its tools are available to any agent with access, within a normal conversation, not as a step in a multi-step flow. > **Warning — The agent respects HubSpot's limits for you** > > HubSpot limits how many requests it can receive per second. If that limit is ever reached, the agent tells the customer to try again in a moment — it never shows a technical error nor leaves the conversation unanswered.
