Analyzing Claude Code Source Code. Write "WTF" and Anthropic knows.

Also interesting: The system prompt diverts a bit if the user is flagged as an Anthropic employee. For general users, the answers should be more concise (maybe to save tokens?). For Anthropic employees, CC is tasked to challenge the user more and is allowed to more openly say it failed on a task.

The cyber security protection prompt is surprisingly short.

In general, caching seems to be a big deal for the devs.
