AI Agents

Microsoft has open sourced code-testing-generator, a polyglot agent that writes unit checks after which proves they work. It ships within the dotnet-test plugin contained in the MIT-licensed dotnet/skills repository. The agent targets a hole that coding assistants normally go away open. A immediate like ‘generate unit checks’ doesn’t say which framework, file location or assertions…

Cloudflare has launched Kitesurf, a stateless net browser constructed particularly for AI brokers. It runs completely in V8 isolates on Cloudflare Workers, with no Chromium beneath. Browser engines like Chromium have been constructed for people, and their reminiscence and compute overhead makes one-browser-per-agent prohibitively costly. Agents don’t want tabs, extensions, or pixel-perfect 60-fps rendering. They…

Prime Intellect has open-sourced Prime Agent, a self-improving coding harness designed round two abstractions, the Recursive Language Model (RLM) and Continual Harness. Fixed software schemas and context compaction power a mannequin to work round its personal scaffolding. Prime Agent replaces each with a persistent Python REPL and a rewritable harness. With Opus 5, it stories…

SkillOpt is a text-space optimizer developed by a staff of researchers from Microsoft, Shanghai Jiao Tong University, Tongji University, and Fudan University. SkillChoose trains a single natural-language talent doc whereas the goal mannequin stays frozen. An optimizer mannequin reads scored rollouts and proposes bounded add/delete/substitute edits. A held-out choice cut up accepts an edit solely…

In this tutorial, we construct a workflow for evaluating the safety posture of AI expertise with NVIDIA SkillSpector. We create an artificial ability market containing clear, dangerous, malicious, and MCP-based examples, then scan every ability by means of SkillSpector’s LangGraph inspection pipeline. We look at danger scores, categorized findings, confidence ranges, analyzer completeness, and executable-script…

Y Combinator crew has open-sourced QM (quartermaster), the multi-agent harness it makes use of internally. QM is described as a multiplayer agent harness for work, working in Slack and on the net. YC crew runs QM throughout accounting, authorized, occasions, and engineering, together with constructing QM itself. The entire venture ships underneath the MIT license….

Three phrases now compete for a similar line in AI engineering job descriptions. Prompt engineering is the established one. Loop engineering entered the AI vocabulary in late 2025 and dominated developer dialogue by means of June 2026. Graph engineering adopted roughly six weeks later. They get used interchangeably. Should they be? The three are usually…
