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.
The bundle reports version 2.1.247, built 2026-08-26T05:55:19Z from commit 89c726188daf6407b6b57bf67d312f2958e5b9f2. It appears in the running-process registration record, the update-failure recovery messages and the /help system prompt block.
