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.

Enhanced Fork Agent Logging

What

Forked agents now log detailed progress information for debugging.

Details
  • Logs transcript recording events
  • Tracks message counts and types received
  • Reports final usage statistics including cache read/create tokens
  • Format: Forked agent [name] finished: N messages, types=[...], totalUsage: input=X output=Y cacheRead=Z cacheCreate=W
Evidence

Logging at line 421675 (contains "Forked agent [", "cacheCreate=", "total sent)")

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