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.

Downloads no longer overwrite an existing file

You'll notice
Useful2 Signal2
Elsewhere

Downloads now fail rather than silently truncating a file that already exists.

What

Update and asset downloads now open the destination with an exclusive-create flag, so a download into a path that already exists fails instead of truncating whatever was there.

Details
  • The write stream is created with { flags: "wx" }, which errors rather than replacing an existing target.
Evidence

createWriteStream(t, { flags: "wx" })

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