• GitHub Copilot CLI 1.0.71-0 pre-release landed on July 10 and pushes the terminal agent further toward first-class workflow control: pinned prompts in /settings, Repo/Repo(local) tabs, lighter targeted validation guidance, cleaner session controls, stricter custom-agent/tool validation, and more robust shell/session error handling.

• Microsoft Agent Framework’s “Agent Harness: Scaling the claw or harness capabilities” extends the harness with on-demand skills, shell access, CodeAct, and background agents, which is a concrete step toward decomposing longer tasks across specialized sub-agents instead of stuffing everything into one prompt.

• Visual Studio’s June update adds more governance around Copilot-driven agent work: refreshed usage tracking with proactive limit alerts, MCP server trust checks before execution, and GA for the GitHub Copilot modernization agent for C++ MSVC upgrades.

• Microsoft Research’s Flint is a new visualization language aimed at AI agents, and the HN Show thread shows real early interest around the idea that agents need higher-level, more reliable chart specs rather than raw low-level plotting calls.

• Microsoft Research’s SkillOpt is another meaningful paper in the same vein: it treats agent skills as trainable parameters, using bounded text edits and validation gating to improve skills without changing model weights.
