Half the year down, and no signs of slowing: a brand-new Skills system, Custom Actions you write yourself, a smarter way to start every workflow, and one of our biggest integration drops ever.
Big Features
Skills: Reusable Instruction Packs Replace the Prompt Library
The prompt library only supported flat text — fine for a one-liner, limiting for anything real. Skills are versioned, reusable instruction packs (in an Anthropic-compatible format) that can bundle supporting files and load at runtime, so your agents pick up the right expertise exactly when they need it. Your existing org prompts have been migrated over automatically, so there's nothing to rebuild.
Custom Actions: Write Your Own Workflow Tools
Sometimes the action you need just doesn't exist yet. Now you can write it yourself: author Python or TypeScript directly in the builder, and StackAI runs it in a secure sandbox and exposes it as a workflow tool scoped to your org. Extending the platform no longer means waiting on us to ship a new integration.
Workflow Builder: Meet the Start Node
Every workflow needs a clear front door, and juggling separate input nodes made that harder than it should be. The new Start Node brings your workflow's inputs — text, URLs, documents, and more — into a single, structured entry point on the canvas, and it carries through to your export interfaces too. Your published apps and APIs now mirror exactly what you designed.
Federated Search: Results That Respect Who's Asking
Until now, federated search ran on builder-configured org connections, so every end user saw the same Slack, email, and Drive results regardless of who was asking. Builders can now let end users bring their own connections for delegated providers, so search results reflect each person's actual access. Personalized, permission-aware answers - no over-sharing.

Quality of Life
Dark Mode Keeps Improving
Settings, project analytics, deployments, and the workflow builder & export screens have all joined the dark side. The whole app is converging on our new design system, so switching themes no longer means bouncing between polished and unpolished pages.
SharePoint Triggers: Pick a Folder, Include Subfolders
Pointing a file trigger at the right SharePoint folder used to mean hand-typing paths and hoping. The folder field is now a proper file picker, and a new toggle lets the trigger watch subfolders too. Set it up in seconds and never miss a file buried one level down.
Outlook: Read Shared Mailboxes
Plenty of teams run support and ops out of shared mailboxes, and the delegated Outlook connector couldn't see them. Now it can - connect once and build workflows on top of the inboxes your team actually shares.
Snowflake: File Output for Huge Query Results
Queries returning more than 100K rows used to be a dead end. Large results now come back as a file URL, so you can pass massive datasets downstream instead of trimming your query to fit.
Send Email: Inline Images
The Send Email action now supports inline CID images, so logos and screenshots render inside the message body instead of arriving as awkward attachments. Your automated emails just got a lot more presentable.
HTTP Request Node: Reach Private Networks on BYOC
If you run StackAI in your own cloud, the Send HTTP Request node can now call services on your private network. Internal APIs are fair game for workflows - no public exposure required.
Bug Fixes:
Action parameter types persist - input and config parameter types no longer reset when you reopen a node.
SharePoint tokens refresh mid-run - long-running workflows refresh expired OAuth tokens instead of failing with a 401.
SharePoint trigger previews fixed - file previews now resolve the download URL correctly.
SharePoint CSV uploads accepted - files reported as application/csv are now treated as valid CSVs.
Google Drive trigger classifies uploads correctly - new files are detected as new even when Drive's modified time lags the created time.
Workable trigger survives republish - republishing a workflow no longer breaks its Workable trigger.
Gmail attachments arrive as URLs - email attachments are now included as usable links in workflow output.
OneNote shared notebooks behave - section and page actions are scoped to the owning site, so shared notebooks work reliably.
Egnyte connections stay alive - connections no longer expire mid-use thanks to proper token refresh.
Azure Blob nested folders visible - knowledge bases now surface nested directories in Azure Blob storage.
Citation page numbers corrected for offset documents - a second class of page-offset error is fixed.
Large file parsing hardened - very large files now parse reliably instead of erroring out.
Oversized uploads fail gracefully - hitting the max file size now returns a clear error instead of an unhandled failure.
Audio nodes fixed in Docker deployments - ffmpeg is bundled correctly so transcription works on self-hosted installs.
Subflows are sturdier - action node outputs are collected inside subflow regions, outer agents resume after nested subflows complete, and tool-call limits are enforced consistently.
Human-in-the-loop timeouts exit cleanly - a timed-out approval no longer wedges the workflow run.
Microsoft OAuth connectors isolated - a global TENANT_ID setting no longer bleeds into individual Microsoft connections.
Batch interface accepts single-column CSVs - one-column uploads import correctly instead of being rejected.
Workflow imports surface clear JSON errors - malformed workflow files now report the exact problem instead of failing cryptically.
Org members columns are sortable - the members page now sorts by any column, so finding people in a large org no longer means scrolling and squinting.
