86%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.
A well-structured, lean skill body: a crisp trigger list, a decision procedure, a six-step migration workflow with a validation checkpoint, and anti-patterns, all appropriately offloading depth to four real one-level-deep reference files and a script. The main gap is the absence of an explicit failure-handling loop in the workflow and a few concrete inline examples deferred to references.
Suggestions
Add an explicit error-recovery loop to the workflow: after Step 5, instruct 'If validation fails: fix the new implementation (not the tests), re-run the full suite, and re-benchmark before proceeding' — this would lift workflow_clarity from 4 to 5.
Inline one canonical example of a documented FFI wrapper (a small Rust snippet with a // SAFETY: comment and catch_unwind) so the most common case is copy-paste ready without opening references.
In the Step 1 command, show expected output of assess-migration.py (or link to the checklist's output format) so the agent knows how to interpret the result.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and prescriptive throughout — no explanations of what Rust, FFI, or memory safety are; every line is instruction ('Never migrate a component without test coverage', 'Document every unsafe block with a // SAFETY: comment'). All 131 lines earn their place; detail is pushed to references. | 5 / 5 |
Actionability | Provides an executable command ('python scripts/assess-migration.py --file <source_file>'), a concrete priority order, specific tool names (Miri, clippy, go vet, rustfmt, catch_unwind), and actionable rules. Not a 5 because common cases (a sample SAFETY comment, a canonical FFI wrapper shape) are deferred entirely to references, leaving minor gaps inline. | 4 / 5 |
Workflow Clarity | A clear six-step sequence with tests-first as a correctness oracle and an explicit Step 5 validation checklist (tests pass, no new unsafe surface, fuzz boundaries, Miri/ASan clean, benchmark). Not a 5 because there is no explicit error-recovery feedback loop — the steps never say what to do when validation fails (fix, revert, re-validate). | 4 / 5 |
Progressive Disclosure | SKILL.md is a concise overview with well-signaled, one-level-deep references ([language-selection.md], [ffi-security.md], [migration-patterns.md], [assessment-checklist.md]) — all four files exist, are substantive, and reference no further files — plus a working script in scripts/. A final References section aids discovery. | 5 / 5 |
