Claude Code Safety Net is a safety-oriented framework and example set designed to help developers integrate runtime checks, guardrails, and defensible constraints into agentic systems powered by Claude Code, with the goal of reducing unsafe outputs, erroneous actions, and harmful behaviors in production scenarios. The repository defines patterns and reusable components for validating agent decisions, sanitizing user inputs, and enforcing operational boundaries, making it easier to design fail-safe integrations with both internal toolchains and external APIs. It includes example safety checks that cover common categories like infinite loops, unsafe system commands, data leakage risks, and visibility constraints, which help engineering teams anticipate and defend against unpredictable agent behavior.
