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.

Stall Detection and Diagnostics

A comprehensive stall detection system has been added that logs timing information for:

  • Stream idle partials: [Stall] stream_idle_partial lastChunkAgeMs=...
  • Classifier requests: start, progress, and finish with timing and outcome
  • Tool dispatch: start, end, and post-error with tool name and permission decision timing
  • Agent completion events

This helps diagnose performance bottlenecks and stuck sessions.

Evidence

Stall detection logs (search for "[Stall]"), with fields like promptTokensEst= and permissionDecisionMs=.

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