What has changed since

An entry is only as true as the day it was written.

Flags move on the server after a release ships. Anthropic's own notes land days later and their documentation later still. Sometimes an entry turns out to be wrong and gets corrected by hand. All of that is recorded against the entry it happened to, and this is the whole of it in the order it happened.

Nothing here replaces an entry. Every line links to the page its release published, still saying what that release said, because a correction is added and dated rather than swapped in.

v2.1.284tengu_lantern_wick_text Flag reading movedThe flag server now returns "Usage limit reached; a short grace allowance remains, then this turn is cut off without warning. Judge what's left: if it's genuinely only a few steps, finish it properly, then stop and say so without extra polishing. Otherwise don't attempt it all: finish the piece in hand and at most two more like it, then stop. The allowance also pays for any subagents you have running: they don't get this message and will keep going, so it's up to you how to handle them. Either way, end by telling the user their usage limit was reached, what's done and what's left." for tengu_lantern_wick_text, read as this account.
