New page: Credentials in managed agents — how to store and manage server-side credentials (bearer tokens, OAuth2, environment variable secrets) so the egress proxy injects them at request time without exposing secrets in the sandbox.

Changelog

Managed agents

  • New page: Credentials in managed agents — how to store and manage server-side credentials (bearer tokens, OAuth2, environment variable secrets) so the egress proxy injects them at request time without exposing secrets in the sandbox.
  • Antigravity Agent 09-2026: Docs now use antigravity-preview-09-2026, which replaces and deprecates antigravity-preview-05-2026 (shutdown October 5, 2026). See the changelog, deprecations, and Antigravity agent guide.
  • Built-in filesystem tools renamed for the new agent (for example write_to_file, view_file, replace_file_content, list_dir), with PascalCase parameters and line-range edits; matcher examples updated on Agent hooks.
  • Agent environment now documents provisioning sandboxes with sources, network rules, environment variables, or a combination.
  • Agents guidance points to managed credentials by ID (and optional inline allowlist headers) instead of header-transformation-only credential injection.
  • Examples and references updated across managed agents quickstart, custom agents, background execution, interactions overview, get started, and latest model.
