System Documentation

What problem does it solve?

Rspack users and developers often encounter crashes, segmentation faults, or deadlocks during builds. This Skill provides a structured approach using LLDB to capture backtraces, identify failing threads, and guide remediation.

Core Features & Use Cases

  • LLDB-based backtrace collection for Rspack processes to diagnose crashes and hangs.
  • Guided workflows for common scenarios (crash during development server, crash during build, attached to stuck process, core dump analysis).
  • Artifact preservation: save backtraces and logs to project files for later analysis.

Quick Start

  • Install LLDB if needed (macOS: xcode-select --install; Linux: apt-get install lldb).
  • Run the automatic setup script to install debug dependencies: node ${CLAUDE_PLUGIN_ROOT}/skills/debugging/scripts/setup_debug_deps.cjs
  • Start the Rspack build under LLDB batch mode to collect backtraces, for example: lldb --batch -o "run" -k "thread backtrace all" -k "quit" -- node node_modules/@rspack/cli/bin/rspack.js build
  • Save the backtrace outputs to a file in your project, e.g., debug_artifacts/backtrace_build.txt
