AI Agent Action: Update tags # AI Agent Action: Update tags The Update tag action allows your AI Agent to **add or remove existing Contact tags** based on the instructions you provide. This is useful for automating **segmentation**, triggering tag-based Workflows, and keeping Contacts organized without manual tagging. ## When to use Use this action when you want the AI Agent to apply tags based on conversation context, such as: * Tag leads based on intent (e.g. %Interested, %Pricing Request) * Tag customers by support topic (e.g. %Refund, %Technical Issue) * Tag contacts once key details are confirmed (e.g. %Demo Booked) ## Best practices * Use % to reference the exact tag name in your instructions. For example: ```html If the Contact asks about pricing, add %Pricing. ``` ```html If the Contact says they are no longer interested, remove %Interested. ``` * You can also view and select from your tags list by selecting the โ€œTagsโ€ icon in the Update tags instruction section. ![](https://assets2-proxy.respond.io/ph8r57dk1q9w/2w2D4sl5GLzyHpstFgR6bs/9c75bc1de6bfbac0a3091bc65cac0208/ai_agent_add_tags_icon.png?fm=jpg&q=80&w=1200&fl=progressive) * Keep your instructions short and unambiguous to reduce tagging errors. * Tags added by AI Agents can be used by human teams and Workflows. For example, a Workflow can start when an AI Agent adds a tag to a Contact. ## Limitations * AI Agents can only **add or remove existing tags to a Contact** โ€” they **cannot create or delete tags**. * AI Agents **cannot read a Contactโ€™s existing tags**, meaning: * They **cannot check whether a tag is already applied in the past** (before the current conversation) * They **cannot use tags to decide conversation logic** (e.g. โ€œIf they already have %VIP, do Xโ€) Share this article [![Telegram](https://assets1-proxy.respond.io/api/v1/image/assets%2F11f7a662b80a4675973850b067c01fa5%2F44daca77a4844f0c8fd29040ddeba057?width=22)](https://api.whatsapp.com/send?text=https://respond.io/help/ai-skills/ai-agent-action-update-tags)[![Facebook](https://assets1-proxy.respond.io/api/v1/image/assets/11f7a662b80a4675973850b067c01fa5/fff57eeb01160bc604392f519b4f3461ca16f0fa1b6a587b20b142cdf1ad0ba7?placeholderIfAbsent=true&width=22)](https://www.facebook.com/sharer/sharer.php?u=https://respond.io/help/ai-skills/ai-agent-action-update-tags)[![Linkedin](https://assets1-proxy.respond.io/api/v1/image/assets/11f7a662b80a4675973850b067c01fa5/7aaf8d87b5410844d83e06a4ed663e4f551b8c5ef51dbb20a8ff064a1eed9a0f?placeholderIfAbsent=true&width=22)](https://www.linkedin.com/sharing/share-offsite/?url=https://respond.io/help/ai-skills/ai-agent-action-update-tags)[![Twitter](https://assets1-proxy.respond.io/api/v1/image/assets%2F11f7a662b80a4675973850b067c01fa5%2F4e03e02422a94e8eab9b8b41457c2371?width=22)](http://twitter.com/share?url=https://respond.io/help/ai-skills/ai-agent-action-update-tags) ## Related articles ๐Ÿ‘ฉโ€๐Ÿ’ป * [AI Agent Action: Add commentsLearn how AI Agents add internal comments in respond.io to share context, tag teammates, and support smooth handoffs. ](/help/ai-skills/ai-agent-action-add-comments) * [AI Agent Action: Assign to agent or teamLearn how AI Agents assign conversations to agents, teams, or other AI Agents in respond.io, including assignment methods, handoff behavior, and key limitations. ](/help/ai-skills/ai-agent-action-assign-to-agent-or-team) * [AI Agent Action: Close conversationsLearn how the Close conversations action works for AI Agents in respond.io, including how to trigger it, apply closing notes, and handle summaries. ](/help/ai-skills/ai-agent-action-close-conversations) * [AI Agent Action: Handle CallsLearn how AI Agents handle inbound calls in respond.io, including voice behavior, setup options, and key limitations. ](/help/ai-skills/ai-agent-action-handle-calls) * [AI Agent Action: Trigger WorkflowLearn how AI Agents trigger existing Workflows in respond.io to run advanced automations and integrations. ](/help/ai-skills/ai-agent-action-trigger-workflow) Can't find what you're looking for? ๐Ÿ”Ž [Contact Support](/contact-us) 2026-10-02T09:04:50.792Z help ```json {"@context":"https://schema.org","@graph":[{"@context":"https://schema.org","@type":"TechArticle","articleBody":"Learn how AI Agents add or remove Contact tags in respond.io to automatically categorize Contacts and support Workflows based on conversation context.","author":{"@type":"Person","image":"https://assets2-proxy.respond.io/ph8r57dk1q9w/2Y6LIr15mC1nj8MgftMVT5/6ffeea71593277f0fc29dafd1c1de9b9/Serene_Avatar.svg","name":"Shing-Yi Tan","url":"https://respond.io/author"},"dateCreated":"2026-01-22T00:00:00.000Z","dateModified":"2026-02-04T05:08:16.730Z","datePublished":"2026-01-22T00:00:00.000Z","headline":"AI Agent Action: Update tags","mainEntityOfPage":"https://respond.io/help/ai-skills","publisher":{"@id":"https://respond.io/#organization"},"url":"https://respond.io/help/ai-skills/ai-agent-action-update-tags"},{"@context":"https://schema.org","@id":"https://respond.io/help/ai-skills/ai-agent-action-update-tags#breadcrumb","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Help","item":"https://respond.io/help"},{"@type":"ListItem","position":2,"name":"Product","item":"https://respond.io/help/product"},{"@type":"ListItem","position":3,"name":"AI Agents","item":"https://respond.io/help/ai-agents"},{"@type":"ListItem","position":4,"name":"AI Skills","item":"https://respond.io/help/ai-skills"},{"@type":"ListItem","position":5,"name":"AI Agent Action: Update tags","item":"https://respond.io/help/ai-skills/ai-agent-action-update-tags"}]},{"@type":"Organization","@id":"https://respond.io/#organization","name":"Respond.io","alternateName":"respond.io","url":"https://respond.io/","image":["https://assets1-proxy.respond.io/api/v1/image/assets%2F11f7a662b80a4675973850b067c01fa5%2F3f43c48b21b24f4e8b02b100c0c8fab0"],"logo":"https://assets1-proxy.respond.io/api/v1/image/assets%2F11f7a662b80a4675973850b067c01fa5%2F4045649d540241d398c39ab07b2b62bb","description":"Respond.io is an AI-powered customer conversation platform that helps businesses manage conversations, automate workflows and scale sales, marketing and support operations.
