85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured reference skill with executable commands, a clear sequenced workflow, and clean one-level-deep references to real bundle files. Its only weakness is mild redundancy: the safety-level mapping is repeated in three body sections and partly duplicates the standards reference file.
Suggestions
Consolidate the DAL A/ASIL D -> MC/DC, DAL B -> decision, DAL C -> statement mapping to a single body location and defer the full per-standard table to references/safety-standards-and-formats.md to remove the triple restatement.
Trim the 'Safety-standard coverage expectations' body section to a one-line pointer to the reference file, since the same levels are already covered in 'How to use' step 1 and the reference matrix.
Consider moving the LLVM coverage-mapping region taxonomy (code/skipped/expansion/branch regions) into a reference file to keep the body focused on the choose-and-wire workflow.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient and assumes Claude's competence (no 'what is coverage' padding), but the DAL A->MC/DC mapping is restated in 'How to use', 'On-target vs host', and 'Safety-standard coverage expectations', and that safety section overlaps references/safety-standards-and-formats.md, so it could be tightened. | 2 / 3 |
Actionability | Provides copy-paste-ready executable commands throughout - 'arm-none-eabi-gcc --coverage -O0 -g ...', 'llvm-profdata merge -sparse raw/*.profraw -o test.profdata', 'lcov --capture --directory . --output-file coverage.info' - plus a fully numbered worked example. | 3 / 3 |
Workflow Clarity | The 'How to use' section sequences a clear 5-step path (criterion -> toolchain -> instrument -> where to run -> produce lcov.info and gate), and the Worked example gives an explicit numbered build/run/report/gate sequence; coverage instrumentation is not a destructive operation so no validate-fix loop is required. | 3 / 3 |
Progressive Disclosure | SKILL.md is an overview with two well-signaled, one-level-deep references - [references/gcov-flag-reference.md] and [references/safety-standards-and-formats.md] - both of which are real files containing the deep flag table and standards/report-format matrices that are correctly kept out of the body. | 3 / 3 |
