32%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is a generic, high-level overview of C++ best practices that provides almost no information Claude doesn't already know. It lacks concrete code examples, executable guidance, and meaningful workflows. The content reads more like a job description or capability summary than an actionable skill that would change Claude's behavior.
Suggestions
Add concrete, executable C++ code examples showing specific patterns (e.g., a RAII wrapper, a move-enabled class, a constexpr function, a CMakeLists.txt template) rather than just listing concepts.
Define a clear workflow with validation steps, e.g.: 1. Write code → 2. Build with CMake → 3. Run sanitizers → 4. Fix issues → 5. Run benchmarks, with specific commands for each step.
Remove the generic 'Use this skill when' / 'Do not use this skill when' boilerplate and the focus areas list of topics Claude already knows; replace with project-specific conventions or non-obvious patterns.
Either provide the referenced `resources/implementation-playbook.md` bundle file or remove the reference and inline the most critical content.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill includes some unnecessary boilerplate (generic 'Use this skill when' / 'Do not use this skill when' sections that add no value) and explains concepts Claude already knows well (what RAII is, what smart pointers are, what STL algorithms are). The focus areas section is essentially a list of C++ topics Claude is already deeply familiar with. However, it's not excessively verbose. | 3 / 5 |
Actionability | The skill provides no executable code examples, no concrete commands, and no specific patterns. It lists high-level guidelines like 'Prefer stack allocation and RAII' and 'Use smart pointers when heap allocation is necessary' which are vague directions Claude already knows. There are no copy-paste ready snippets, no CMakeLists.txt examples, and no concrete template patterns despite claiming to cover these areas. | 2 / 5 |
Workflow Clarity | The 'Approach' section provides a rough sequence of priorities but lacks any concrete workflow steps, validation checkpoints, or feedback loops. The 'Output' section lists expected deliverables but doesn't explain how to produce or validate them. There's no build-test-validate cycle described despite mentioning sanitizers and benchmarks. | 2 / 5 |
Progressive Disclosure | The skill references `resources/implementation-playbook.md` but no bundle files exist to support this reference, making it a dead link. The content that is present is relatively flat with no meaningful structure beyond basic headers. There's no clear navigation to deeper resources, and the reference that does exist is vaguely described ('If detailed examples are required'). | 2 / 5 |
