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.

Date Change Notifications

What

Long-running sessions now receive automatic notifications when the date changes at midnight.

Details
  • Claude is informed of the new date without user intervention
  • Helps maintain accurate context for date-sensitive operations
  • The message instructs Claude not to mention the date change explicitly to users
Evidence

Date change handler (search for "The date has changed. Today's date is now")

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