1. I connected an AI assistant to our OutSystems platform. The biggest lessons were about trust.
By Nelson Pinto

In his article, Nelson shares his experience and lessons learned from connecting an AI assistant to the OutSystems platform using Model Context Protocol (MCP) tools to automate daily code quality reports.

2. Building an Offline Sync for OutSystems Mobile Apps That Survives the Real World
By By Henrique Silva

Tired of telling clients to "keep the app open until it finishes syncing"? Henrique built an open-source background sync plugin that moves heavy uploads into native code, and it synced a 418 MB audit with the screen locked. You'll learn how to use the outbox pattern to add it to an app already in production, and when to pick it over the built-in TriggerOfflineDataSync. It's on the Forge for both O11 and ODC.

3. AI Can Make Good Software Great. It Can Also Make Bad Software Worse
By Ana Bandarra

If you've ever typed "no bugs, please" into an AI prompt, this one's for you. Ana argues that AI amplifies what you bring to it: clear prompts get better results while weak prompts make it worse. You'll learn when OutSystems Mentor actually adds value and how to leverage that value for better results!

1. Beyond accuracy: Architecting performant, cost-efficient agentic AI
By Rushikesh Kulkarni
Your AI agent doesn’t need the entire company wiki to swap a conveyor fan. Rushikesh takes on the “mega prompt trap” with an architecture fix that cut one workflow from 413K tokens to 84K, nearly halved latency, and brought hallucinations down from 20% to 2–5%. Before you upgrade to a fancier model, check your architecture. Your CFO will be grateful.

2. How to master row concatenation in SQL for OutSystems apps
By Fábio Godinho
One course, five instructors, one tidy comma-separated line. Fábio covers STRING_AGG() for modern databases, the STUFF() + FOR XML PATH() workaround for older SQL Server, and JSON aggregation for API payloads. At the end, he has Mentor build the whole thing in under two minutes. It’s like learning long division right before someone hands you a calculator, and you’re better for having done both.

3. AAA framework: Building bulletproof security in OutSystems
By Mauro Henriques (co-authored with Mário Cunha)
Knowing who's knocking isn't the same as letting them in. Mauro and Mário walk through Authentication, Authorization and API security patterns for the Agentic Era. That means signed JWTs, picking between RBAC, ABAC and permission-based access, a fail-closed "ensure permission" wrapper, and the shadow entity pattern for record-level security. Hiding a button in the UI is cosmetic. Server-side checks are what protect your data.
