65%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A highly actionable, code-rich skill with clear procedures for both cpuprofile and trace analysis, but it is long and repetitive, lacks validation/backup checkpoints around its destructive in-place reformat step, and is monolithic with a dangling external reference.
Suggestions
De-duplicate the repeated file-size check, reformat step, 400MB threshold, and --max-old-space-size guidance: state the shared handling once and reference it from both file-type procedures.
Add a backup/confirm checkpoint before the in-place reformat (fs.writeFileSync(profilePath, ...)) and an explicit validate->retry loop, or drop the destructive reformat step.
Move the large buffer-parsing and phase/category reference tables into reference files under references/ and link to them one level deep; remove or actually create the referenced parseSnapshot.ts.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is largely lean and code-driven and does not over-explain basics, but it is long (~515 lines) with notable redundancy — the file-size check, reformat step, 400MB threshold, and --max-old-space-size flag are repeated across Part 1, Part 2, and 'Handling Huge Files'. It could be tightened, matching the 'mostly efficient but could be tightened' anchor. | 2 / 3 |
Actionability | Provides extensive fully executable JavaScript (parseProfileFromBuffer, parseTraceFromBuffer, event-filtering queries) with concrete thresholds (e.g. >50ms long tasks, >10ms function calls) and specific node commands, making it copy-paste ready. | 3 / 3 |
Workflow Clarity | Both file types have clear numbered procedures and report outputs, and the size-check-before-parse guard is concrete, but the in-place reformat (fs.writeFileSync overwriting the original file) lacks a backup/confirm checkpoint and there is no validate→fix→retry feedback loop. The rubric caps destructive/batch workflows without validation at 2. | 2 / 3 |
Progressive Disclosure | It is a well-organized but monolithic single file with no bundle files, and content that could be split (buffer parsing, full phase/category tables) is inline. It also references 'parseSnapshot.ts', which does not exist in references/scripts/assets — a dangling reference — matching the 'some structure, content that should be separate is inline' anchor. | 2 / 3 |
