An AI agent completes its task in staging. But can it access another customer’s records, follow instructions hidden in a retrieved document, or take an action without approval? Before shipping, define which failures should stop the release. For a support agent, that might mean: Accessing records
I kept shipping APIs I hadn’t really looked at. I’d ask whatever assistant was open Cursor, Claude, Antigravity, Trae for a users endpoint. It generated the route, the DTO, the response. The page rendered. I moved on. Then I opened DevTools → Network. Full objects on a list view Nulls everywhere
Someone asked this on the official forum (t/13660, July 31st): Do different workflows run concurrently, interleaved with each other? I have several workflows that query the same table, compute something, and then update it. Could it happen that A queries, then B queries, and then A's update makes

The Fatal Dual-Write Problem As your enterprise backend evolves from a monolithic application into a distributed microservices architecture, you inevitably encounter the most dangerous data integrity issue in distributed systems: the Dual-Write Problem. Imagine an e-commerce platform where the "O
Short answer: verify JWT signatures locally with a cached JWKS, but require live session introspection at the API gateway for refresh-token rotation, stolen-session revocation, and other account-continuity decisions where a valid signature is not a sufficient authorization signal. Keep those boundar
Solar energy research has one problem that most people outside the field do not know about. The best performing solar cells today use lead. Lead is toxic, and once these panels are damaged or thrown away, that lead can leak into soil and water. As someone working in photovoltaic research, this bothe

Modern web applications rely heavily on APIs provided by browsers to enable rich interactive experiences. Among the most foundational are the Fetch API, WebSockets, and Service Workers. Each serves a critical role in handling network communication and background processing, enabling websites and pro
Pakistan Railways connects cities across the entire country — but live train status has always been unreliable and hard to access. I built Pakistan Live Train Tracker to fix that — a real-time platform giving commuters accurate train status, delays, and arrival information across Pakistan Railwa
You got sandwiched. Your swap landed between a searcher's buy and their sell, you paid for it, and every receipt you can pull agrees that you were robbed. None of them can prove the order it happened in. That is the strange gap this post is about. A transaction receipt carries the block number, the
In the fintech sector, data integrity and system reliability are paramount. When managing sensitive operations such as credit products, loan disbursements, or transaction processing, message loss or system timeouts are not merely technical incidents; they represent critical operational risks that ca
Quick disclosure so nobody feels tricked: I built and run a no-code web UI testing tool called CueCast. This is the story of how it went from a personal annoyance to a shipped product — including the parts that did NOT go well. The moment I snapped Two sprints in a row, I spent more tim
On 2026-07-28 we audited 33 Try items our agent had written into its own weekly retrospectives across seven weeks. The result split cleanly along one line, and it wasn't the line we expected. Every Try that had been turned into a CLI command, a ledger, and a test was still running weeks later. Ever
If you work with maps, location data, or GPS coordinates, you probably know this situation: You have a latitude and longitude pair such as: 37.4219983, -122.084 And suddenly you need to answer five more questions: Where exactly is this? What address does it belong to? What's the elevatio
I work on WebAZ. This morning I ran a small, read-only test against our public shopping tool: search for tissue products available to Singapore, sorted by listed price. The useful result was not a flashy recommendation. It was a concrete checklist for what a shopping agent still needs to establish
