Why is my Claude Code session slow / hung / not authenticating?

Pick the branch by what just happened: install/login failures, settings not applying, hung tool calls, auto-compact thrash, or slow search on WSL. Most 'Claude is broken' reports resolve into one of those five plus a /clear.

How do I add, remove, and debug MCP servers from the command line?

claude mcp add takes transport (http/stdio/sse), scope (local/project/user), and env vars. All options must come before the server name. mcpServers in settings.json is silently ignored: use .mcp.json or the CLI instead.

Why isn't my CLAUDE.md / settings.json taking effect?

Check three things in order: which file Claude is actually loading (precedence runs user → project → project-local → CLI args → managed), whether your edit is shadowed by a higher layer, and whether the change needs a session restart. Most no-effect cases are precedence, not bugs.
