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.

Context Over-Limit Warning Improved

What

The message shown when the context window is exhausted now distinguishes between the auto-compaction window and the raw model limit, and always names the specific action to take.

Details
  • Auto mode: Context exceeds the N-token limit by M tokens — run /compact or /clear to continue.
  • Non-auto mode: Context is M tokens past the N-token compaction window — run /compact to reduce usage.
  • If DISABLE_COMPACT is set: suggests only /clear
Evidence

Context limit message (search for "Context exceeds the" or "Context is" combined with "token compaction window").

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