GitHub commits on the platform nearly doubled year over year, crossing 1.4 billion per month, with over 2 billion GitHub Actions minutes logged per week. That scale exposes a real problem: existing developer tools were not built to manage multiple agents running in parallel. Context scatters, work loses traceability, and pull requests arrive without a clear record of what the agent attempted or where human judgment is required.
GitHub's answer, announced at Microsoft Build, is the GitHub Copilot app, now in technical preview for Copilot Pro, Pro+, Business, and Enterprise users. A single My Work view surfaces active agent sessions, issues, pull requests, and background automations across connected repositories. Each session runs in its own git worktree, isolated and managed automatically, no manual branch setup. A feature called Agent Merge monitors CI, tracks required reviewers, addresses failing checks, and merges only when developer-defined conditions are met.
The more interesting architectural move is canvases, bidirectional work surfaces where agents post plans, browser sessions, terminals, and deployment states as inspectable, editable objects. This is what GitHub is calling agent experience, or AX: interfaces designed for humans and agents operating on the same surface simultaneously. The full piece covers how cloud and local sandboxes fit into this loop, and why the worktree-per-session model is the structural bet GitHub is making on durable agentic workflows.
