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.

Generated identity keyed to the machine, not the user

Under the hood
Useful2 Signal3
Identity

An internally generated identifier is now tied to your machine rather than your user account.

What

An internally generated identifier is now derived from and stored as a machine ID rather than a user ID, and the helper takes the store to write into as an argument.

Details
  • An older telemetry block that bucketed a hashed ID by modulo for sampling and posted events in batches was deleted in favour of a lazily created instance.
Evidence

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