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.

Quality

Content

81%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A highly actionable, well-sequenced skill body with concrete commands and strong validation/feedback loops. Its main weaknesses are mild redundancy (the debug-id and non-symbolicatable-frame points recur) and all content being inlined rather than split into reference files.

Suggestions

Dedupe the exact-debug-id-match guidance: state it once in step 3 and have the callout/Tips reference it rather than re-explaining.

Move the "Remote Extension Host crashes (Linux, gdb)" section into a separate reference file (e.g. references/remote-gdb.md) and link to it, improving progressive disclosure and keeping the main flow on electron-minidump.

Consolidate the repeated "not every frame can be symbolicated / attribute by module" guidance into a single spot in "Reading the result" instead of restating it in step 2, step 3, and Tips.

DimensionReasoningScore

Conciseness

Largely efficient and focused on specialized operational knowledge Claude would not know (cache layout, debug-id matching, private repo access), but the exact-debug-id-match point and the "not every frame can be symbolicated" point are each restated across step 3, the callouts, and the Tips section, so it could be tightened; not verbose enough for a 2 but with enough redundancy to fall below the "efficient" 4 anchor.

3 / 5

Actionability

Fully executable, copy-paste-ready commands throughout — npm install, electron-minidump invocations with a retry loop, gh release list/download, unzip/cp with correct quoting, strings greps, and gdb commands — covering the common Windows and macOS cases, matching the top anchor.

5 / 5

Workflow Clarity

A clearly sequenced four-step procedure with explicit validation (inspect the log for frames lacking method names) and a feedback loop ("If some frames are still bare, return to step 2"), plus a transient-error retry loop, matching the "explicit validation steps with feedback loops" anchor.

5 / 5

Progressive Disclosure

Well-organized into clear sections (Prerequisites, numbered Procedure, Reading the result, Creating a crash report, Remote Extension Host crashes, Tips) with no nested references, but everything is inlined in SKILL.md with no separate reference files — the tangential gdb/Linux section is a candidate for its own reference file — placing it just below the one-level-deep reference ideal of 5.

Description

87%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description that names concrete actions, gives explicit "Use when..." trigger guidance, and carves out a clearly distinct niche. It uses correct third-person voice with no first/second-person slips.

DimensionReasoningScore

Specificity

Lists several concrete actions — "Symbolicate a native VS Code crash dump", "resolve missing method names in a native crash backtrace", "attach Electron/Insiders/Stable symbol files" — with only minor coverage gaps, fitting the "several specific actions" anchor rather than the fully comprehensive 5.

4 / 5

Completeness

Clearly answers both: what ("Symbolicate a native VS Code crash dump (.dmp) using electron-minidump") and when ("Use when given a crash dump file, asked to symbolicate a crash, resolve missing method names...") with concrete trigger phrases, matching the top anchor.

5 / 5

Trigger Term Quality

Natural terms a VS Code team member would say are well covered — "crash dump file", "symbolicate a crash", "attach symbol files", ".dmp" — but a few common synonyms (e.g. "stack trace", "backtrace" beyond the one mention) are absent, so it is just below comprehensive.

4 / 5

Distinctiveness Conflict Risk

A narrow niche — VS Code native crash-dump symbolication with team-only private symbol access — with distinct triggers and minimal overlap risk with other skills.
