46%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 compact and names the right tools and standards (clang-tidy, valgrind, -Wall -Wextra, C99/C11), but it contains generic template boilerplate, offers no executable code or completed example, and its single progressive-disclosure reference points to a file that does not exist in the bundle. It reads more like a domain outline than operational guidance.
Suggestions
Fix or remove the dangling reference to `resources/implementation-playbook.md` — the file does not exist in the bundle, so the promised detailed examples are unreachable.
Replace the boilerplate Instructions section with concrete C-specific guidance, and complete the Example section with a worked input/output pair (e.g. a code snippet plus a sample review covering a leak and a missing return-value check).
Convert the Approach principles into a sequenced review/build workflow with explicit validation checkpoints (e.g. compile with -Wall -Wextra -Werror → run tests → valgrind → report findings).
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The Focus Areas and Approach lists are lean and domain-specific, but generic boilerplate pads the skill: "Clarify goals, constraints, and required inputs. Apply relevant best practices and validate outcomes. Provide actionable steps and verification" and the template-like "Do not use this skill when" / "Limitations" sections tell Claude nothing it doesn't know. This matches 'Mostly efficient but includes some unnecessary explanation or could be tightened'. Not a 4 because the Instructions section is almost pure filler; not a 2 because the core technical content is not explained or padded. | 3 / 5 |
Actionability | Concrete anchors exist — "Use static analysis tools (clang-tidy)", "Makefile with proper flags (-Wall -Wextra)", "Unit tests using CUnit", "Debugging with valgrind and gdb", "Follow C99/C11 standards" — but there is no executable code, no sample commands, and the Example section contains only a user request ("Review this C implementation...") with no example output or worked response. This is 'Some concrete guidance but incomplete... missing key details'. Not a 4 because nothing is copy-paste ready and the lone example is a stub; not a 2 because specific tools and flags are named rather than vague hints. | 3 / 5 |
Workflow Clarity | The "Approach" section is a numbered list ("1. No memory leaks - every malloc needs free / 2. Check all return values..."), but these are best-practice principles rather than a sequenced process, and checkpoints are implicit — e.g. "Valgrind clean output demonstration" names a validation artifact without any validate-fix-retry loop or order of operations for a review task. This matches 'Steps listed but validation gaps; sequence present but checkpoints missing or implicit'. Not a 4 because there is no clear operational sequence for the skill's stated example task (reviewing a C implementation); not a 2 because the numbered approach and named validation tools give more definition than the minimal anchor. | 3 / 5 |
Progressive Disclosure | The only external reference is "If detailed examples are required, open `resources/implementation-playbook.md`" — but no such file exists anywhere in the bundle (there are no resources/, references/, scripts/, or assets/ directories), so navigation leads to a dead end and the promised detailed examples are simply absent. The body's own section structure is reasonable, but a dangling pointer to a nonexistent file is a structural/navigation failure, fitting 'Minimal structure... or references are buried' territory. Not a 3 because a clearly signaled but broken reference is worse than the 'references present but not clearly signaled' anchor implies — the referenced content does not exist at all; not a 1 because the body is short and well-sectioned rather than a monolithic wall of text. | 2 / 5 |
