Karellen Rr
Claude Code plugin for rr reverse debugging via MCP. Automatically configures the karellen-rr-mcp MCP server and includes a crash detection hook that suggests rr when a command exits with a signal (SIGSEGV, SIGABRT, etc.) or sanitizer output is detected, a debugging skill with the full record-replay-analyze workflow, and an rr-investigator agent for autonomous crash investigation through reverse execution. Requires Linux x86-64 with rr, gdb, and pip install karellen-rr-mcp.
