我不断撞上 AI 编码工具的“配额墙”，于是我构建了一个路由器

Users of AI coding tools like OpenClaw, Codex, Cursor, or Claude Code often encounter the issue of their premium model quota depleting midway through the week. An analysis of usage logs revealed that most prompts were not complex but rather mundane utility tasks such as 'summarize this paragraph', 'reformat this JSON', 'explain this error', and 'convert this to TypeScript'. These simple requests do not require high-end models but were being sent to them, consuming quota rapidly. After a week of logging, the distribution of usage was consistent: approximately 55% of requests were simple, 25% medium complexity, and 15% complex.
