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 state writes preserve worktree provenance

You'll notice
Useful3 Signal0
Worktrees

Agent records keep their worktree history across saves, so lineage info no longer gets wiped.

What

Persisting an agent record no longer loses the worktree lineage fields that were set by an earlier write.

Details
  • A new persistence wrapper reloads the previous agent record before writing.
  • It carries over parentAgentId, inheritedWorktreePath, spawnedWithWorktree and worktreeCleanlyRemoved.
  • worktreePath and worktreeBranch are deleted when the prior record had none.
Evidence

inheritedWorktreePath

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