Sebastian Raschka breaks down the six core building blocks of coding agents like Claude Code and Codex CLI — covering tool use, context management, prompt-cache stability, repo context, memory, and long-session continuity. The piece argues that the surrounding agentic harness, not just the model, drives the performance gap between chat interfaces and dedicated coding agents. A solid reference for developers building or evaluating AI-powered dev tools.

Brace for the patch tsunami: AI is unearthing decades of buried code debt

AI vulnerability discovery tools like Claude Mythos and GPT-5.5-Cyber are unearthing buried security flaws faster than organizations can patch them, giving both defenders and attackers automated access to exploit intelligence at scale.
