Codex and Claude Code usage limit guides

OpenAI Codex and Anthropic’s Claude Code both cap usage over a few hours and over the week. These guides explain how each limit works, where to see what is left and when it resets, and what to do when you run out. Each one is checked against the official OpenAI or Anthropic documentation and links to it.
