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.

Remote-driven file reads get their own admission and re-verification path

Under the hood
Useful2 Signal4
Remote Execution

Reads from another session go through an admission check and re-verify the path after reading.

What

Reads driven from another session now resolve the file through an admission check that must return "admitted", otherwise the read is refused back to the caller as an invalid request. After the bytes come off disk the path is checked again, and if it no longer points where it did, the cached read state is dropped and the caller is told to read again.

Details
  • Remote-driven reads bypass the read-first guard-skip heuristic and the read dedup cache.
  • They also skip dynamic skill directory triggers, skip pending handover reads, and never open an IDE diff tab.
  • Local reads take none of these branches; the whole path is conditioned on the call carrying a remote-call context, with no flag involved.
Evidence

Served file call refused at read time

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