Newsletter Title

Copilot Local Sandboxing Makes Agent Permissions Concrete

Intro

GitHub Copilot app local sandboxing turns agent permissions into per-project policy, which is the right default shape for developer machines.

Takeaways

  • Local sandboxing now applies to local repository and working tree sessions in the GitHub Copilot app.
  • Agent risk is usually described in abstract terms: prompt injection, unintended commands, overbroad credentials, or accidental writes.
  • The project settings describe the policy the app requests when a sandboxed session starts.
  • The preview is interesting because it makes local agent governance less hand-wavy.
