Daily Agentic Field Watch - 2026-06-16 09:00 UTC

• GitHub Copilot CLI is becoming more selective about delegation: GitHub says the harness should choose between a larger model, specialist subagent, or procedural skill based on task, repo context, policy, and expected outcome. That is a genuine control-plane change, not just another model swap. Source: https://github.blog/ai-and-ml/how-we-made-github-copilot-cli-more-selective-about-delegation/
• MAI-Code-1-Flash is now being framed in Microsoft’s Build 2026 keynote transcript as a lightweight agentic model built into GitHub Copilot and VS Code. The r/GithubCopilot follow-up adds live rollout detail: pricing is showing up, and Biz/Enterprise expansion is still pending.

• Microsoft 365 Copilot Agent Builder now supports file uploads up to 512 MB in the release notes, which helps the grounding workflow even though Copilot Chat file upload/download limitations are still separately listed in known issues.

• Enterprise governance pressure is showing up in r/microsoft_365_copilot: UK/EU admins are asking how Anthropic gets reviewed and enabled inside Copilot, which suggests subprocessor/compliance review is now part of the rollout bottleneck.

• HN and GitHub have a fresh coding-agent build signal in rho, a Rust-based headless agent with a Deno extension runtime and a trait-based frontend system. Sources: https://news.ycombinator.com/item?id=48528779 and https://github.com/crustyrustacean/rho-coding-agent.git
