@GitHub in Slack and Teams now works across multiple repositories in one conversation and can use shared Slack messages and threads as context

Track PRs and investigate issues across repositories from chat, without switching conversations.

// Key points

  • One conversation can span repositories, for example listing your open PRs everywhere, what merged this week, or an issue spanning frontend and backend repos.
  • Mentioning @GitHub anywhere in a message now works, not only at the start.
  • @GitHub can use shared Slack messages and threads as context without copy and paste.
  • GitHub also improved reliability, with fewer errors, faster task startup and smoother recovery from interruptions.

Builder's takeMy products are multi-repo microservices, and checking PRs across repos is the most time-consuming daily chore, so this fits a pre-standup progress summary directly. Note that reading Slack threads as context brings chat content into Copilot’s scope, so admins should decide which channels allow that before turning it on.
