Security tools have gotten good at spotting patterns. But attackers don’t think in patterns, they think in systems.
Claude Code Security reasons through your entire codebase like a human security researcher. It traces data flows, understands business logic, challenges its own findings, and then proposes targeted patches for human approval.
Not just “here’s a vulnerability.” But “here’s why it matters and here’s a fix.”
The adversarial self-verification step is especially interesting. Fewer false positives. More signal. Less wasted analyst time. Released in limited research preview, this feels like a shift from static scanning → contextual reasoning.
Hot question: does this make AI code review tools obsolete?
Short answer: not immediately.
Long answer: tools focused on PR reviews and developer productivity operate earlier in the lifecycle. Claude Code Security feels deeper, more like an AI security researcher auditing entire systems.
If it continues improving at finding novel, logic-level flaws (not just surface bugs), it could compress a huge amount of specialized security review work.
Obsolete? Probably not overnight.
Pressure on them to evolve? Absolutely.
What do you think... augmentation layer or category killer?
I lova Claude Code, but it's not so easy to optimize it for a beginner, so it seams I have to spend a high amount of hours to really understand, what is possible with this tool. But its great in total.
