Developer luchasarie released bro-skill, a single-file Agent Skills-format skill named `/bro` that re-explains an AI assistant's own previous message in plain language without adding new information. The skill installs v…
Dbmask, an open-source Python tool posted to Show HN, discovers sensitive columns in SQL databases, masks them with deterministic fake values, and validates the results. The tool targets test data handling friction in en…
Combining Claude Projects, which pin a permanent knowledge base of documentation and code to a workspace, with Skills implemented via the Model Context Protocol (MCP) lets developers manage an autonomous development envi…
Shopify is migrating all of its mobile apps back to native Swift and Kotlin, reversing its 2020 bet on React Native, according to a September 10 engineering post. A six-engineer team rebuilt the Shop app fully native in …
A serial founder launched Natively, an open-source MIT-licensed agent-to-agent communications platform, after his agents generated 500+ unread emails in a single thread. The founder said his only contribution to the proj…
OpenAI launched the Agents API in public beta on September 10th, a managed service that runs the Codex harness and cloud infrastructure so developers can build long-running agents without assembling their own agent loops…
OpenAI released the Agents API, giving applications access to the Codex harness through an OpenAI-managed API that handles sessions, orchestration, context compaction, and recovery while the application supplies tools an…
Published AI agent skills from Anthropic, Microsoft, Google, and community repositories such as Matt Pocock's rarely deliver the desired result because they encode the original author's assumptions, shortcuts, and trade-…
Organizations are overlooking citizen developers in their governance and developer training programs for AI-assisted software development, according to SD Times, even as agentic AI reshapes the software development lifec…
Software developer Dave Winder used Anthropic's Claude inside the Cursor editor to write a few hundred lines of Swift in a single morning, creating a working macOS app called Windley Microscope for his 25-year-old Intel …
