  • policywrites require the child configuration to expose an editing tool and remain subject to VS Code trust and approval controls
Evidence
  1. 1. Evidence checked 2026-08-28: Claude Code subagents can inherit Edit and Write tools or receive an explicit tool allowlist; `acceptEdits` and worktree isolation provide documented write-control modes.
  2. 2. Evidence checked 2026-08-28: VS Code custom agents used as subagents can receive the `edit` tool, and the official coordinator example assigns code-writing work to an Implementer child.
