Hooks that do not block, permission paths that anchor elsewhere and MCP switches aimed at the wrong list: how to find settings that load fine and do nothing.
A Claude Code configuration is a small piece of JSON plus a few scripts, and the tool is forgiving about it. A rule with a wrong shape is usually skipped, a hook that never matches simply never runs, and the session starts as normal. That is convenient while you experiment and dangerous once a team relies on the file, because the failure has no message. You find out when the protection was supposed to act and did not. This guide goes through the places where a setting reads as correct and does nothing: hooks, permission rules, the settings files themselves and MCP server switches. Each one comes from the official documentation, and each can be checked in a few minutes.
