I asked Claude Code to implement something trivial in my repo. Three turns later, we’d burned 80K tokens because the agent had a hard time finding the right part of the codebase that contained the logic it needed. Weaviate v1.37.1 ships an MCP server built into the database.

Prompt cache diagnostics are now in Claude Console. When a request misses the cache, you can now see exactly which part of your prompt changed and how many tokens it cost you.

AI labs have started developing systems to monitor internally deployed AI agents for misaligned behavior. Earlier this year, I spent a month embedded at Anthropic stress-testing these systems, to see how easily current/future AIs could “go rogue” inside the company.
