message-flow-troubleshooter

What problem does it solve?

This Skill helps diagnose broken or inconsistent message delivery across a client, an intermediate routing layer, and an LLM provider, especially when replies disappear, become malformed, or stop at the proxy.

Core Features & Use Cases

• Two-sided inspection: Compare the client’s original request with the provider’s raw response to determine whether the failure starts on the left side, the right side, or in the middle.
• Restart-first triage: When the middle layer is down or blocking traffic, restart immediately before spending time on deeper analysis.
• Code-level fallback: If a restart does not fix the issue, switch to targeted logic debugging instead of repeated full-chain guessing.
• Use cases: Cursor receiving empty output, tool-call loops, truncated messages, proxy crashes, and message transformation bugs.

Quick Start

Ask the assistant to inspect the client request, the provider’s raw response, and the middle-layer logs, then decide whether to restart the proxy or trace the transformation bug.
