I worked with a group of engineers to create github/lever - a library of skills for automating boring work so that us humans can focus on the things we love.
We pooled our session history, mined it for the patterns that produce the best results, and turned them into low barrier skills.

1.2B users. ~40 regions. Single-digit-millisecond latency. One team.
@AzureCosmosDB and @OpenAIDevs engineers scaled it together. Read the story 👇
We serve data in milliseconds to more than 1.2 billion users across 40 geographic regions.
To reach that scale, we worked closely with @AzureCosmosDB on our storage architecture, achieving a 12x improvement in global median read latency.

Dependabot pull requests are easy to review one at a time ... and tedious to review by the dozen.
Build a GitHub Copilot app automation that does the first pass for you. Once it reviews open Dependabot pull requests, groups them by risk, verifies CI status, it'll provide a short summary.
You write the instructions in plain language, so you can shape the automation to match how your team works. Schedule it before your workday starts and the results are ready when you log in.
Try it out 👇

The GitHub Copilot SDK is no longer the CLI/SDK and is now just the Runtime/SDK.

Privileged to work daily with the talented @stephentoub @stevensanderson @shayrojansky @MackinnonBuck @edburns @brunoborges @Scott_Addie (and now so many teams) on the shared runtime for so many products/platforms.

GitHub just put the Copilot agent permission layer under ENTERPRISE control.
Admins can govern:
- Shell commands
- File reads
- File edits
- Network domains
Each operation can be blocked, require fresh human approval, or run without a prompt.
And the user cannot bypass the policy with auto-approval, saved approvals, workspace settings, or YOLO mode.
GA in the Copilot app, CLI, and VS Code Agent Host.
Block credential folders.
Require approval for git push.
Allow approved tests.
Agent governance just moved into the execution layer.
This is the move.

Microsoft is just one beneficiary of 250 years of American history and the choices made by past generations. As an American company, we believe we have a responsibility to understand where we have been, learn from it, and help make real for others the opportunities created for us.
As America enters its 251st year, we face another inflection point shaped by rapid technological change. That is why we created this series. Throughout July, we will reflect on moments in American history with six video episodes when people faced uncertainty and made choices that set in motion consequences they could not fully see. Some decisions advanced the country. Others revealed how much work remained. Together, they remind us that history is not inevitable; it is made by people, in moments, through choices.
Our goal is not simply to celebrate that history, but to learn and connect the past to the questions we face today. Because one of the best ways to honor 250 years of American history is to think seriously about what we will do next.
Stay tuned for episode 2 next week. aka.ms/America250
