Changelog

April 17, 2026

Image vision for Zendesk attachments

• AI reads image attachments — When an agent encounters an image attachment on a Zendesk ticket (JPEG, PNG, GIF, WebP), it downloads the image, encodes it, and sends it to the AI model for visual analysis. The agent can describe screenshots, read text in images, identify products, and parse receipts.
• Vision-capable models — Works with GPT-5.4 Mini, GPT-5 Mini, GPT-4o Mini, Claude Sonnet 4.5, and Claude Sonnet 4. Groq models gracefully return a "not supported" message.
• Shared image utility — Reusable download + base64 encoding helper available for all connectors. Future connectors (Freshdesk, Slack) can add image reading with a single function call.

GPT-5.4 Mini

• New model available — OpenAI's latest mini model with a 400K context window (3x larger than GPT-5 Mini). Stronger reasoning, better instruction following, same image vision support. 1.25 credits per message.

Zendesk custom fields tool

• Read custom field values with labels — New Get Ticket Custom Fields tool returns every custom field on a ticket with its title resolved from the field schema. No more raw field IDs — agents see "Bestellnummer: 013724827106" instead of "field_1900003089273: 013724827106".
• Schema caching — Field definitions are cached per connector for 5 minutes, so the schema fetch only happens once per connector window.

Zendesk subject update tool

• Update ticket subject lines — New tool to change a Zendesk ticket's subject. Validates 1-150 character length. Requires confirmation in chat mode.

Trigger context & conversation audit

• Structured trigger data — Each connector's trigger definitions now include a contextSchema that declares which payload fields to extract for the UI. Ticket ID, subject, and requester are stored on the conversation for frontend display.
• Raw payload preserved — The full webhook payload is saved on every autonomous conversation for audit and debugging.
• Richer conversation history — Autonomous conversations show connector icon + event label in the sidebar and agent history modal. Conversation titles use the extracted fields instead of the event label prefix.

Tool & trigger advisories

• Activation confirmation modals — High-impact tools (Add Public Reply, Update Ticket Status) and triggers (Every Customer Message, New Ticket) now show a confirmation modal when toggled on, with a severity-themed warning and custom confirm/cancel labels.
• Persistent advisory cards — Enabled tools and triggers display an advisory note on the agent configuration page — a short, always-visible summary of how to use the tool safely.

Zendesk OAuth improvements

• Refresh race fix — Concurrent refresh attempts no longer clobber each other's tokens. The race condition that caused the Schmid Digital outage (two webhooks racing on a single-process Node server) is resolved with compare-before-write logic.
• Reconnect flow — New Reconnect button in the connector modal for OAuth connectors. Re-authenticates in place — same connector ID, no tool stripping, no agent breakage. A new email template directs customers to the Reconnect flow.
• Re-auth preserves credentials — The OAuth re-auth path now preserves all existing credential fields (webhook IDs, signing secrets) instead of replacing the entire blob.

Credit alert improvements

• Persistent dedup — Credit usage alerts (50%, 80%, 90%) are now tracked in the database instead of an in-memory set. No more duplicate emails after deploys.
• Single admin notification — Admin credit alerts fire once per threshold crossing, not once per customer admin in the org.

UI improvements

• Tool activity results — Autonomous conversation tool cards now show success/error banners with the actual result (not just "Completed"). Failed calls show the error reason + dimmed args with "Attempted payload (not sent)".
• Image preview in tool cards — Image attachment results render a thumbnail preview with broken-image fallback.
• Scrollable org switcher — The organization dropdown scrolls when the user belongs to many orgs, keeping Settings and Log out visible.
• Past conversations expanded — The sidebar conversations list is expanded by default for paid plans.

Zendesk OAuth

• Global OAuth client approved — Zendesk has approved Macha's global OAuth client. OAuth is now the default authentication method for new Zendesk connections, replacing API key auth.

Confluence connector

• 7 tools — Search pages, read content, list spaces, get child pages, create pages, update pages, and add comments. Write operations require confirmation.

• Auto-creates source — Connecting Confluence automatically creates a data source, just like Google and Notion.

AI Agent Builder & Editor

• Build agents through conversation — Describe what you need and the AI creates a fully configured agent with instructions, tools, triggers, sub-agents, and model selection. Available on all plans.

Scheduled triggers

• Cron-based agent execution — Schedule agents to run on recurring intervals (hourly, daily, or custom cron). 60-second polling loop with guardrails: min 1h interval, 24 runs/day cap, 3 org concurrency limit.
• Auto-disable on errors — Triggers disable after 5 consecutive failures with email notification. Stale lock cleanup at 30 minutes.

Sub-agents

• Multi-agent delegation — Agents can delegate tasks to specialist sub-agents, each with its own tools, model, and knowledge base. Up to 3 levels deep with circular reference prevention.
• Seamless UX — Sub-agent tool calls stream with indentation in the status log. Tools used by sub-agents appear in the "Tools Used" popup on saved messages.

Test Run

• Simulate with real data — Search for real tickets, emails, or documents from the agent config page. Select one and the agent processes it in a test conversation with live SSE streaming.
• Simulation schema — Every tool and trigger across all 14 connectors defines a simulation property for entity search and formatting.

Google Picker for document sources

• Native file selection — Select Google Docs and Sheets for agent data sources using the native Google Picker API instead of manually entering document IDs.

• Edit agents with AI — Open the AI editor from any agent's configuration page to modify instructions, add tools, set up triggers, or wire up sub-agents through conversation.
• Context-aware suggestions — The builder knows your connected integrations and suggests relevant agent configurations. Hover over suggestion pills to preview prompts.
• Artifact cards — Created agents, triggers, and tools appear as interactive cards in the chat. Click an agent card to navigate directly to its configuration.

Sub-agent enhancements

• Write permissions in autonomous mode — Sub-agents can now execute write operations (replies, updates) when running via triggers. They remain read-only during interactive chat for safety.
• AI builder support — The AI Agent Builder can assign sub-agents when creating new agents, with automatic circular dependency checks.

Agent configuration improvements

• Save guard — The save button is grayed out when there are no changes. A confirmation modal appears when navigating away with unsaved edits.
