Copilot for Teams: Org-Level Custom Agents, Thinking Controls, and Git Pre-PR Review

GitHub Copilot's August 28 Visual Studio update ships three team-scale features: org-owned custom agents auto-populate every repo's picker, supported models get Low/Medium/High thinking effort controls, and the Git agent can review uncommitted changes before you open a PR.

Org-level custom agents: org and enterprise owners publish a custom agent once — it appears automatically in every repository's agent picker with its description and org label. Any Copilot tier can use an org agent; you need org or enterprise owner permissions to publish one. Per-repo setup is no longer required to distribute team knowledge.

Thinking effort controls (Low/Medium/High): available on supported models to trade reasoning depth for token cost per request — the same per-request pattern as Claude Code's /effort and Gemini 3.7 Flash's thinking_level.

Git agent pre-PR review: from the Git Changes panel, trigger the Git agent to review uncommitted changes or specific commits; findings surface inline with a navigable list. Supports both GitHub and Azure DevOps repositories.

Why it matters: Org agents solve the distribution problem — the same runbook or review-style agent your team maintains, automatically available in every repo without per-repo configuration.
