what is RCF ? I have developed a tool promptCape https://gbreton7.gitlab.io/promptcape to protect against AI assistant (PI/RGPD/code) and it is so far used by companies which wants some level of protections as they do not control what is made of their data and code by AIs. Before that, some of them completely prohibited the use of non-local AI. They recently asked me to integrate promptCape as a terminal in cursor for claude code they have started to use. what do you think ?
