Developer builds Chrome extension to prevent screen-share mishaps and data leaks

·1 views

A developer created ScreenGuard, a Chrome extension, after a viral post described a founder accidentally opening an adult website while screen-sharing with a CEO. The extension works locally in the browser and offers two core features: warnings before potentially risky or phishing-style links open, and a screen-share protection mode that blurs sensitive data such as API keys, email addresses, and payment details. The tool is designed to intervene only when necessary, avoiding constant permission prompts that could frustrate users during normal browsing. ScreenGuard is free and currently at version 1.0.15, with the developer actively seeking feedback from professionals who frequently share their screens. The creator is targeting developers, founders, educators, and sales teams, and wants to refine the product before expanding its feature set.

FlowScript 0.1 Debuts as a Semantic Language for Modeling Apps Before Coding

Developer Erland Kjensli has publicly released FlowScript 0.1, an experimental domain-specific language designed to describe the semantic model of an application before any implementation begins. The project addresses limitations of traditional flowcharts, which struggle to capture the full complexity of modern apps including state, navigation, UI structure, and dataflow. FlowScript separates structural hierarchy, navigation graphs, and state graphs as distinct but related concepts, aiming to reduce ambiguity in application modeling. A key hypothesis behind the language is that responsive UI layouts can be treated as projections of a single underlying semantic model rather than separate application hierarchies. The initial release is available as a working draft on GitHub under version 0.1.0.

Encoding API contracts in tool schemas beats prose descriptions for smaller LLMs

A developer team discovered in May 2026 that two AI models — Opus 4.7 and Sonnet 4.6 — produced different JSON outputs from the same tool description, with the smaller model returning an incorrect structure that triggered downstream 422 errors. The root cause was not a capability difference but an exposure gap: the larger model had seen the proprietary field names during training, while the smaller one guessed plausible-sounding alternatives. Because tool descriptions are prose rather than enforced contracts, models without prior exposure to a custom schema have no validated structure to follow. The team resolved this by migrating the structural contract into the JSON schema itself, using discriminated oneOf branches with strict required fields for the nine most common pattern types. They applied a permissive fallback branch for rare pattern kinds, limiting the upfront effort to roughly one afternoon while targeting the failures that actually occurred in production.

Developer Discovers AI Agent Was the Cause of Missing Disk Space

A developer recently shared an ironic experience where an AI agent was tasked with investigating missing disk space on their system. The investigation revealed that the agent itself was the culprit, having consumed the storage it was sent to find. The anecdote quickly gained attention in developer communities for its humorous and self-referential nature. It highlights a growing concern about the unintended resource consumption of autonomous AI agents. The incident has been dubbed a distinctly modern tech problem, reflective of how AI tooling is evolving in 2025 and beyond.

Oracle AI Agent Studio's Retirement Assistant Simplifies Fixed Asset Retirement Process

Oracle AI Agent Studio offers a Retirement Assistant that replaces the traditional multi-step fixed asset retirement workflow in Oracle Fusion Cloud with a conversational interface. The tool allows accountants to retire assets by typing free text or uploading a CSV file, eliminating the need to navigate multiple menus or work areas. The assistant validates inputs in real time, identifying missing fields such as retirement dates and flagging errors with specific, actionable guidance before any changes are posted. It works alongside a companion agent called the Retirement Request Assistant, which lets business users submit retirement requests that are then routed to accountants for processing. Together, the two agents form a front-office and back-office pairing designed to streamline the end-to-end asset retirement workflow.
