April 1st, yesterday afternoon, the developer Chaofan Shou wrote in X and released it directly Anthropic Command Line Tool under Flag Claude Code The full-source compression package generated widespread interest in the developers community. The post was viewed 12 million times in hours。
The cause of the event was that Anthropic forgot to delete the .map file (Source Map) when sending a package to the npm public mirror library. The function of such documents is to map compressed, confused production codes back to their original source code to facilitate local debugging, but to delete them when they are officially released is fundamental。
It was this mistake that led to nearly 2,000 files, more than half a million lines of TypeScript code being publicly exposed online。
IN THE LEAKED SOURCE CODE, DEVELOPERS REMOVE MULTIPLE UNPUBLISHED FEATURES. THE HIGHEST LEVEL OF DISCUSSION WAS THE PROJECT CODE NAME BUDDY - A PLAN TO END IT"Sebo pet."System.
THE PETS ARE BASED ON THE HASHI VALUES OF THE USER ID, AND EACH IS UNIQUE, PRE-SET 18 BIOLOGICAL FORMS, INCLUDING DUCKS, DRAGONS, DOLPHINS, GHOSTS, ETC., AND HAVE A RARE SYSTEM OF "NORMAL" TO "1% LEGENDS", AS WELL AS FIVE DYNAMIC VALUES: DEBUGING (TEMPORAL), PATIENCE (RESISTENCE), CHAOS (MIXING), WISDOM (SMART) AND SNARK (NEGATIVES)。
The source code indicates that this feature was planned for April 1 to 7 as egg preheating, and that internal measurements were open to internal employees of Anthropic in May。
ANOTHER FEATURE OF INTEREST IS KAIROS' "ALWAYS ONLINE" AI ASSISTANT。The assistant is able to keep an ongoing memory across sessions, store user work habits and project background in a private directory, and have the right to initiate the task。
It is worth noting that the source code also contains a mechanism called "Nightly Dreaming" — the automatic initiation of backstage processes at night, retroactivity on the day, the removal of redundant information, and the deposition of core content into long-term memory to prevent the context logs from expanding indefinitely。
