Source Intelligence

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.

Directory sync gains between-tool pumps and a post-command pull

File Sync

Files changed by a remote command are pulled back and summarised between tool calls.

What

When the sync engine supports them, two background pumps now run between tool calls: one pulls down what remote commands changed, one performs uploads that are due. After a command runs on a remote machine, the files it changed are pulled back and summarised in a note such as "3 files updated here from ...".

Details
  • Inside a subagent, pulled files are not written immediately; the write is deferred until the task hands back to the main conversation, and the reminder says so.
Evidence

Directory sync: ${u} sent what that command changed, but those files are written here only after this task hands back to the main conversation

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