本地路由代理把低复杂度请求分流到便宜模型（ClawRoute）

• OpenClaw/Cursor/VS Code traffic can be pointed to a local proxy endpoint.
• You have at least one low-cost model and one high-quality model configured.
• You can run Node.js services locally and monitor request logs.

1. Deploy a local proxy process between your client and provider endpoints, keeping all request inspection on-device.
2. Implement a first-pass complexity classifier (simple vs complex) using lightweight heuristics and optional dry-run mode.
3. Route simple prompts to cheap models (e.g., flash/mini class), and reserve premium models for complex coding/reasoning tasks.
4. Track per-request cost deltas and compare dry-run vs active routing before enabling by default.
5. Add guardrails for misclassification fallback (retry on premium model when confidence is low).

• The reported 60-90% saving is self-reported by the author and depends on workload mix（需验证）.
• Wrong complexity classification can degrade answer quality; keep fallback and periodic audit enabled.
