The new GitHub app for Teams: from conversation to code (devblogs.microsoft.com)

GitHub announced a reimagined GitHub app for Microsoft Teams that embeds a Copilot-powered coding agent directly into Teams conversations. The preview lets teams convert discussion into action—assign tasks to the app, have it write code, open pull requests, and request reviews without leaving a channel. It uses repository awareness and code search to surface relevant files and history, respects organization policies (e.g., branch protections), and shows step-by-step progress as it executes fixes. Setup is straightforward: install, connect your GitHub account, pick a default repo, and invoke the agent with @GitHub. For the AI/ML community this represents a practical shift toward conversational, model-in-the-loop engineering workflows that reduce context switching and accelerate iteration (bug fixes, feature delivery, tests, docs). Key technical implications: the agent blends generative assistance with repo-aware retrieval to ground outputs in your codebase, and integrates with existing review and CI processes to preserve governance. Because it’s in preview, teams should evaluate accuracy, potential hallucinations, and security implications (data access and policy enforcement) while providing feedback. This is the first step toward deeper GitHub functionality in Teams and signals broader adoption of conversational coding assistants in collaborative workflows.
