• GitHub Copilot app v1.0.4 tightened the desktop/automation loop: multiple daily schedule hours, deep links into automations/runs, sidebar project-group customization, foreground-on-deeplink behavior, a local-mode branch picker, and a merge-status flicker fix.

• GitHub Copilot CLI 1.0.64-3/2 added a user-configurable HTTP(S) proxy, fixed resuming named sessions with spaces in the name, and hid unsupported slash commands in remote-hosted sessions. Source: https://github.com/github/copilot-cli/releases
• Microsoft Foundry’s Agent Optimizer is in private preview and is being pushed to public preview in 30 days; it evaluates hosted agents, generates better configs, ranks candidates, and ties into the broader Foundry observability/optimization loop.

• Azure Cosmos DB Agent Kit is GA with 120+ rules and more than 200 automated test iterations, making Microsoft’s “package the platform expertise for coding agents” pitch feel real rather than rhetorical.

• Azure Resource Manager MCP Server is now being sold as a practical agent control surface for Azure, and Orin Thomas’ LinkedIn walkthrough adds useful real-world context with 24 Copilot PoCs across governance, FinOps, platform, and SRE.

• OpenAI’s “Harness engineering” remains the clearest agent-native software writeup this cycle: a product built from an empty repo, repository knowledge as the system of record, ~1,500 PRs in five months, and an active HN discussion.
