DomScan Creator Shares REST API Workflow for Thorough Domain Research

·1 views

Esteve Castells, the maker of DomScan, has published a tutorial detailing how to build a structured domain research workflow using the platform's REST APIs and MCP. The workflow covers sequential checks including domain availability, WHOIS and RDAP registration data, DNS and email security records, and algorithmic valuation estimates. Castells emphasizes preserving three distinct availability outcomes — confirmed available, confirmed registered, and undetermined — warning that an unknown result should never be treated as availability. Each API endpoint returns evidence with timestamps and caveats, and developers are advised to retain that context rather than flattening results into simple pass or fail values. New DomScan accounts receive 10,000 free monthly credits with no payment card required to get started.

Why AI Agents Hallucinate Their Own Actions and How to Engineer Around It

AI agents built on the ReAct (Reason + Act) architecture frequently fabricate tool outputs, file paths, and function results — not due to bad prompts but because of a structural flaw in how large language models process their own actions. Since an agent's entire memory of past steps exists only as text tokens in a context window, the model has no verified execution trace to anchor its reasoning. Research indicates hallucination rates can climb from around 5% in single-turn tool use to 20–40% in multi-turn loops exceeding ten steps, as compounding errors reinforce flawed reasoning. The root cause lies in how autoregressive models are optimized for fluency and plausibility rather than factual accuracy, causing them to reconstruct or invent tool responses when outputs are large or ambiguous. Addressing this requires architectural solutions such as sandboxing, verified audit trails, and honest agent design that decouple execution state from the model's interpretive context.

Key Multi-Agent Design Lessons from AutoGen That Still Apply Today

Microsoft's AutoGen framework entered maintenance mode in October 2025 after its team merged with the Semantic Kernel team to form the unified Microsoft Agent Framework, ending new feature development while keeping critical fixes active. AutoGen was widely used to learn multi-agent system design, and several of its core architectural ideas remain relevant regardless of which framework developers use next. One key principle is that shared conversation history serves as the system's state record, eliminating a separate workflow database but risking bloated context if not kept concise and structured. Another lesson is that speaker-selection logic should only invoke a model when genuine judgment is required, since deterministic routing rules are cheaper, faster, and more predictable for straightforward task-type decisions. AutoGen also demonstrated the value of assigning different model tiers to different agents — using expensive frontier models only for complex reasoning steps and smaller, cheaper models for formatting, extraction, and routing to control costs.

Vaadin Lets Java Developers Build Full Web UIs Without JavaScript Frameworks

Vaadin is an open-source Java framework that enables developers to build complete web application user interfaces entirely in Java, without writing HTML, CSS, or JavaScript directly. Its core product, Vaadin Flow, handles client-server communication automatically and generates frontend code from server-side Java logic. Key built-in features include annotation-based routing, a data Grid component with sorting and lazy loading, and a Binder class for form validation tied to data models. The server-driven architecture keeps business logic and UI state on the server, improving security but increasing memory usage per active session. For teams wanting a more reactive approach, Vaadin also offers Hilla, which pairs a Spring Boot backend with a React frontend and auto-generates type-safe TypeScript endpoints from Java services.

Solo Developer Builds 73-Line Script to Guard macOS Automation Schedules from Silent Rewrites

A solo developer discovered in late August 2026 that an unknown process had silently reduced their automated outreach DM jobs from eight daily runs to just three, costing them missed opportunities for several days before they noticed. The developer relies on macOS launchd-scheduled Python scripts to run social media outreach across Instagram, Threads, and YouTube while they sleep, with automation uptime directly tied to their income. Because macOS does not alert users when a plist configuration file is modified, the jobs appeared active in launchctl even though they were running on altered schedules. In response, the developer built a 73-line shell script called outreach-schedule-guard.sh that detects unauthorized plist changes, logs the modification timestamp, captures a snapshot of running processes for forensic review, and automatically restores the correct configuration. The tool was designed not just to fix the problem but to preserve evidence, allowing the developer to distinguish between their own scripting errors and potential outside interference.
