Read original →Claude Code introduces "verification loops" and "skills" to automate the code review and correction process. These loops allow Claude to transform manual checks, such as linting, testing, or specific project requirements, into an iterative process where the agent automatically verifies its work and attempts to fix issues. By encoding these manual steps as skills, developers can enable Claude to close its own feedback loop, autonomously iterating on code changes until they meet predefined criteria, thus freeing up developers for other tasks. The system offers both built-in verification features and the ability to create custom loops for project-specific best practices.
Read original →Outtake has developed the "Recon Agent," an autonomous cyber investigator built on Claude using Claude Code and the Agent SDK. This AI-powered agent detects, investigates, and dismantles sophisticated digital threats, from cloned login pages to entire adversarial networks, which are increasingly accelerated by AI. Unlike traditional security tools that only guard one part of an attack, the Recon Agent unifies defense by mapping the full digital trust attack chain and conducting long-running investigations. This enables a comprehensive "agentic defense" against modern, AI-driven cyberattacks that bypass legacy security solutions.
