GitHub keynote: agents shift coding bottleneck to review; Anthropic adds Agents.md
marlene_zw · x · 2026-09-19
GitHub's Marlene Mhangami published slides from her AGNTCon + MCPCon Europe 2026 keynote — and revealed she asked for Anthropic to support Agents.md during Thursday's talk; it shipped Friday.
Key points:
- Agents now write more code, faster — the bottleneck moves from writing to reviewing and understanding, hitting open source maintainers hardest
- GitHub is evolving its experience for human+agent collaboration: richer issues and PRs, stacked PRs, AI overviews and findings
- Real controls are needed to keep open source healthy
Slides available as click-through deck, PDF and PowerPoint with speaker notes — a primary source on GitHub's agent strategy.
