• Copilot Cowork is now generally available worldwide, with multi-model support and usage-based billing for long-running, multi-step enterprise tasks. Microsoft says it is grounded in Work IQ and security/compliance controls, and Satya Nadella amplified the launch on LinkedIn.

• GitHub Copilot code review now reads root-level AGENTS.md, so repository instructions can shape review feedback automatically. GitHub also tightened the draft-review request flow and collapsed noisy timeline events, which is a concrete step toward standardizing agent instructions across review workflows.

• The GitHub Copilot app shipped v0.2.30 with a Remote sessions setting and an Agent merge reply attribution toggle, plus a quicker Quick Chat terminal and other workflow polish. The repo is still actively iterating on the agent-native desktop experience.

• Satya Nadella’s June 15 post, “A frontier without an ecosystem is not stable,” argues that companies need to own their learning loops instead of letting a few frontier models capture all the value. It is the clearest recent Microsoft strategy note on why enterprise agent systems need ecosystem, governance, and compounding organizational knowledge.

• Microsoft also published a new playbook for investigating AI incidents, aimed at reconstructing activity across Microsoft 365 Copilot and Azure AI services using existing security signals. This is mostly a governance/security item, but it matters for enterprise agent operations because it turns agent behavior into something investigators can actually trace.
