71%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is concise, actionable, and well-structured for a self-contained skill, with concrete code for both GC models. Its main weakness is workflow clarity: verification commands are listed but not framed as explicit validate-then-proceed checkpoints with error-recovery loops for fragile codegen operations.
Suggestions
Turn the verification section into an explicit sequence with a checkpoint: compile → inspect stack map → if missing, confirm setGC ran before RewriteStatepointsForGC → only proceed when the stack map is present.
Add a short error-recovery note tying common verification failures (no stack map, stale pointer use) back to the matching 'Common mistakes' item.
Tighten a few evaluative asides ('Easy to implement', 'advanced / understanding only') to keep the tone purely instructional.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly lean and efficient — step tables and code blocks earn their place with minimal padding — though a few framing sentences ('Easy to implement', 'advanced / understanding only') could be trimmed without losing clarity. | 4 / 5 |
Actionability | Provides concrete, executable C++ and LLVM-IR snippets plus shell commands for both models, with only minor gaps (the manual-emission C++ API is left as 'prefer the pass' rather than a complete example). | 4 / 5 |
Workflow Clarity | Steps are sequenced (Step 0 → A/B → verify → common mistakes), but the verification section lists commands without an explicit validate-then-proceed checkpoint or error-recovery loop, and there are no validation gates for the destructive/irreversible codegen operations the rubric flags. | 3 / 5 |
Progressive Disclosure | For a self-contained single-purpose skill under 50 substantive lines with no external bundle files, the content is well-organized into clear sections (model choice, gcroot, statepoints, verification, mistakes), which satisfies the simple-skill exception for a top score. | 5 / 5 |
