symbolicate-crash-dump
Symbolicate a native VS Code crash dump (.dmp) using electron-minidump. Use when given a crash dump file, asked to symbolicate a crash, resolve missing method names in a native crash backtrace, or attach Electron/Insiders/Stable symbol files. VS Code team members only; requires macOS or Linux.
Why this skill is useful
Adds specific commands and procedures for symbolizing crash dumps using electron-minidump that the AI wouldn't reliably generate on its own.
What it needs
Requires electron-minidump installed locally. Requires github account access. About 6k tokens when loaded. Last updated 2026-08-07. 188,455 stars on the source repository.
What this skill does
Symbolicate a Crash Dump Turn a native VS Code crash dump (.dmp) into a readable backtrace with method names using electron-minidump. VS Code team members only. Symbol files for internal Electron, Insiders, and Stable builds live in a private-adjacent release repo. A macOS or Linux device is required — electron-minidump does not run on Windows. Prerequisites A crash dump file (.dmp). See Creating a crash report below if you don't have one yet. A global install of electron-minidump: For Insiders/Stable symbols, an authenticated GitHub CLI (gh auth status) with access to the private microsoft/vscode-electron-prebuilt repo. Procedure 1. Run an initial symbolication pass This generates or refreshes the electron-minidump cache and tells you which symbols are still missing. Inspect symbolicated-output.log. Look at the top frames of the backtrace: if a frame names a module (e.g. Electron Framework) but has no method name after it, symbols for that module are required. Retry on transient download errors. electron-minidump downloads symbols from public symbol servers, so a run can fail on a transient network error (e.g. failed to download ... (code 56) or (code 28)). Successfully downloaded symbols are cached, so simply re-running the same command resumes where it left off. Retrying a few times is expected: 2. Get the appropriate symbol files Match the symbol source to the build that produced the crash: Build that crashed Symbol files source -------------------- --------------------- Insiders / Stable (internal Electron) microsoft/vscode-electron-prebuilt releases Code - OSS (OSS Electron) electron/electron releases microsoft/vscode-electron-prebuilt is a private repo — this is why the flow is team-members-only. …
