  The   claude   CLI tool has rapidly become essential for power users integrating LLM workflows directly into the terminal. However, developers attempting to optimize their throughput by running parallel sessions—one for a backend migration, another for writing unit tests—often hit a hard wall. You open a new tab, run  claude , and suddenly your active sessions terminate. The console spits out  Request aborted  or, more cryptically, a Cloudflare  Error 525: SSL Handshake Failed . This isn't a network outage. It is a state management conflict inherent to how modern CLI tools handle authentication persistence. This guide details the root cause of these crashes and provides a robust shell-level implementation to isolate your sessions. The Root Cause: Race Conditions in State Files To fix the crash, we must understand the architecture of the  claude  CLI authentication flow. When you authenticate via  claude login , the tool writes an OIDC ...

  Windows developers leveraging the new   Claude Code CLI   research preview often hit a wall immediately after installation. When running the tool inside the Windows Subsystem for Linux (WSL2), two specific blockers arise:   EACCES   permission errors during the global npm install, and a runtime crash stating "Sandbox requires socat" or missing bubblewrap dependencies. These errors occur because standard WSL Ubuntu distributions are minimized environments lacking specific networking utilities and process isolation tools that Claude Code relies on for safe execution. This guide provides the root cause analysis and the exact commands to stabilize the environment. The Root Cause: Process Isolation and Permissions To understand the fix, you must understand the architecture of the tool. Claude Code is not just a text generator; it is an agent capability that executes terminal commands and modifies files. To prevent the agent from accidentally damaging your host syst...
