While current mainstream AI programming assistants (such as Claude Code, Codex, Gemini CLI) are powerful, they have systemic flaws when executing autonomously. They tend to guess the meaning of unread code, submit modifications without checking, create duplicate files instead of editing existing ones, and fail to learn from past mistakes. The root cause of these issues lies in the lack of structured execution constraints and cross-session memory mechanisms.
The traditional solution is to write detailed instruction files telling agents the rules to follow, but instruction files can only provide suggestions and cannot enforce compliance. GOAT Flow's core insight is: Agents need a set of non-skippable mechanisms, not just rules they should remember.
