Runtime Evidence Debugger

关于

The Runtime Evidence Debugger skill provides a structured, hypothesis-driven workflow for resolving difficult software defects. By automating the setup of a local logging server and providing standardized instrumentation patterns, it allows developers to capture real-time values, state transitions, and execution flows. This skill is especially useful for debugging issues that are hard to reproduce or require specific user interactions, as it replaces manual DevTools inspection with programmatically accessible, structured logs that Claude can analyze directly to confirm or reject root-cause hypotheses.

主要功能

• Automated local log server setup with session-based tracking
