DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Agent Worktree Isolation Option

What

Agents can now specify an isolation field to run in an isolated worktree.

Usage

Agents can be configured with isolation: "worktree" to run in a temporary git worktree or hook-based worktree for isolated work.

Details
  • Creates an isolated copy of the repository for the agent to work on
  • Supports both Git worktrees and custom hook-based worktrees
  • Useful for agents that need to make changes without affecting the main working directory
Evidence

Isolation parsing in agent frontmatter (search for "isolation", "Isolation mode")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
