Improve CLI for Agent Compatibility and SafetyPublic

The user wanted to improve their command-line tool to be more compatible with automated agents by implementing stricter input handling, better help documentation, and safer backward-compatible changes. They reviewed recommendations, ensured existing users would not be broken, and worked in a separate branch to isolate these updates. The outcome was a set of documentation updates and initial code changes to enforce stricter argument parsing and enhanced CLI behavior, with plans to create a pull request including this trace.
