Upwind Expands AI Agent Protection With Context Scanning and Runtime Detection

The security problem posed by AI agents is not really about the models themselves. It is about everything wrapped around them: the skills, the tools, the connections, and the instructions that determine what an agent actually does once it is set loose in a live environment. Upwind Security is tackling that problem directly with two new releases: the AI Agent Context Scanner and the general availab...

Corrective RAG for billing: the bug is not retrieval, it's the model narrating correct numbers wrong

Most RAG demos are graded by an audience that cannot check the answer. Ask a docs bot something, get a fluent paragraph back, nobody in the room knows whether sentence three is invented. The demo lands. Billing is not like that. When a subscriber asks "why is my bill higher this month" they are holding the invoice. They will check. We built a WhatsApp assistant for an ISP that answers plan and b...

Running One Compliance Flow Across Two Countries That Don't Agree on Much

Running One Compliance Flow Across Two Countries That Don't Agree on Much Nigeria and Kenya have different numbers of steps in their compliance flow. They don't structure director and shareholder data the same way. Business type changes what's even required. And on top of all that, there's an admin review process where a reviewer can reject three fields out of forty and the applicant ha...

Stop Wrestling with cURL: Meet glassnode-php, an Unofficial Glassnode SDK for PHP

Integrating on-chain metrics into a PHP product should not require every developer to become an HTTP error-handling specialist first. Yet that is often the reality: hand-written cURL calls, manually assembled query strings, JSON decoding scattered through services, and generic exceptions that make production incidents harder to diagnose. The problem becomes even more consequential when requests co...

Kubernetes: Monitoring the Cluster with Prometheus

🇧🇷 Leia a versão em português aqui. Once a Kubernetes cluster is up and running, monitoring what's happening inside it — CPU and memory usage, number of active replicas, application latency — stops being optional. Prometheus is today's de facto standard for monitoring in the Kubernetes ecosystem: a time-series database that periodically collects metrics (pull model) and lets you query and alert o...

A Lei de Conway (DRAFT com Mermaid): por que a sua arquitetura é o espelho da sua organização

Melvin Conway publicou em 1968 uma observação que arquitetos de software ignoram por décadas, redescobrem a cada incidente em produção e voltam a ignorar na reorganização corporativa seguinte: "Qualquer organização que projete um sistema (definido de forma ampla) produzirá um design cuja estrutura é uma cópia da estrutura de comunicação da organização." A frase não é sobre tecnologia. É sobre ...

How to Test AI Agents Without Calling More LLMs

AI-agent testing often starts with an expensive loop: call the agent, send its answer to another model, ask for a quality score, and hope the score is stable enough for CI. LLM judges can be useful for genuinely semantic questions. They are a poor default for verifying tool order, retry limits, validation, budgets, state transitions, or error handling. Those behaviors have explicit contracts and ...

LLD Data Structures in Design Context: Why HashMaps Feel So Fast — Understanding Performance Without Memorising Big-O

"A HashMap feels fast not because computers became magically faster. It feels fast because the design avoids doing unnecessary work." In the previous articles, we built our understanding of how HashMaps work. We learned: Why fast lookup is an important system behaviour. Why unique keys help software systems retrieve information quickly. How hashing converts keys into predictable locations. W...

Trace digests for LLM monitoring, at 1/30th the price of Sonnet

Trace digests for LLM monitoring, at 1/30th the price of Sonnet

We run one LLM call on every agent trace we ingest: it reduces the trace to a short, searchable digest. Because it runs on every trace from every customer, it is the most frequent LLM call we make, and its cost is the one that grows fastest with our usage. So we tested whether a cheaper model could do it. Sonnet 4.6 writes that digest today at about $3.45 per 1,000 traces, and plenty of models co...

One Contract, Multiple Enforcement Points for Safe AI Agent Execution

Overview A lot of AI agent safety discussion still stops too early. People talk about: prompts instructions guardrails whether the agent "knows better" Those things matter, but they are not where the real control lives. If an agent can ignore the instructions, pick the wrong execution path, skip the real verification lane, or claim success without independent evidence, then the re...

Your AI Memory Store Needs a Delete Key

Most memory implementations for AI applications are append-only. New memories go in, nothing ever comes out, and every stored item stays equally retrievable forever. That works fine for the first few hundred entries. It stops working somewhere in the thousands, and the failure is quiet, because retrieval quality drops while every dashboard still looks healthy. The fix is not a bigger vector index...

What I Learned Building an AI Background Remover on Cloudflare

I recently shipped CutoutKit, a small web app that removes image backgrounds and returns a transparent PNG. The interface is intentionally simple: upload an image, wait a few seconds, and download the result. The implementation behind that flow was less simple. Once I moved past the prototype, I needed authentication, usage limits, payments, webhook reliability, privacy boundaries, and an archite...
