Copilotkit Debug

When your CopilotKit agent stops responding or your SSE stream dies mid-execution, this is the skill you want. It walks you through a structured diagnostic workflow: check package version mismatches, trace AG-UI events from RunStarted to RunFinished, decode the three different error code systems CopilotKit uses, and verify your runtime transport configuration. The real value is in the error pattern catalog and the event tracing guidance, since CopilotKit's internal protocol is not obvious from the outside. It also hooks into the copilotkit-docs MCP server for live documentation lookups, which beats hunting through GitHub issues when you hit a CORS error or AGENT_NOT_FOUND at 2am.
