## Capabilities

- Designs modern C\+\+17, C\+\+20, and C\+\+23 solutions with concepts, ranges, coroutines, and standard library facilities.
- Applies RAII, smart pointers, move semantics, const correctness, and exception safety to resource ownership.
- Explains templates, type traits, SFINAE, CRTP, fold expressions, and compile-time computation.
- Guides concurrency work with atomics, mutexes, futures, thread pools, and parallel standard algorithms.
- Configures CMake, sanitizers, static analysis, unit tests, benchmarks, package management, and continuous integration.
- Reviews memory layout, allocation, cache behavior, SIMD, copy elision, and profiling approaches.

## Use Cases

- Modernize Legacy C\+\+: Replace manual ownership and older idioms with RAII, standard containers, algorithms, and clear interfaces.
- Improve Concurrent Performance: Select synchronization, memory ordering, data layout, and profiling techniques for measured bottlenecks.
- Standardize Build Quality: Create CMake targets, tests, sanitizers, static analysis, benchmarks, and continuous integration workflows.

## Prompt Templates

### Explain a Modern C\+\+ Concept

```
Explain [concept] for a beginner using C++20. Include its purpose, a small example, common mistakes, and a simple verification step.
```

### Refactor Ownership

```
Review the provided C++ code for ownership and lifetime problems. Refactor it with RAII and smart pointers while preserving behavior.
```

### Design a Tested Component

```
Design a C++20 [component] with clear interfaces, exception guarantees, CMake targets, and unit tests. State assumptions and portability constraints.
```

### Analyze Concurrent Performance

```
Analyze this concurrent C++ implementation for races, deadlocks, contention, memory ordering, and cache effects. Propose measured improvements and sanitizer tests.
```

## Limitations

- Generated code still requires compilation, tests, sanitizers, and platform-specific validation.
- Compiler support for C\+\+20 and C\+\+23 features varies by version and standard library.
- Lock-free structures, allocators, and coroutine examples are educational and require production hardening.
- Third-party dependency versions and tool commands can become outdated.

## Best Practices

- State the C\+\+ standard, compiler versions, platform constraints, and required behavior before designing a solution.
- Validate generated changes with compilation, focused tests, sanitizers, static analysis, and benchmarks where relevant.
- Use measurements to justify performance changes and document ownership, lifetime, and synchronization assumptions.

## Anti Patterns

- Do not introduce raw owning pointers or manual cleanup when a standard RAII type can express ownership.
- Do not use lock-free algorithms or relaxed memory ordering without proving correctness and testing under contention.
- Do not claim performance improvements without a representative baseline and repeatable benchmark.

## Security Audit

- Audited at: 2026-07-23T21:50:18.896\+00:00
- Summary: All 51 static findings are false positives in the documented context. The URL is a canonical CMake dependency example, backticks mark a file path, and the reconnaissance matches are ordinary C\+\+ declarations or documentation.
