reviewing-cpp

reviewing-cpp is a skill for Claude Code from qte77/claude-code-plugins. It costs 44 tokens per session (785 once invoked), scanned A, original, Apache-2.0.

A code-review skill for C++ desktop applications built with wxWidgets, GTK3, or Qt. It examines memory use, framework patterns, build configuration, and thread safety.

In plain words
What is it for?
Use it to review changed C++ desktop code and its CMake build files, with feedback tied to specific files and lines.
Why use it?
It helps find leaks, dangling pointers, unsafe resource handling, incorrect GUI patterns, and build or concurrency problems before they reach users.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

reviewing-cpp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 21d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

C++ Desktop Code Review

Scope: $ARGUMENTS

Delivers focused, streamlined C++ desktop code reviews matching stated task requirements exactly. No over-analysis.

Workflow

  1. Read task requirements to understand expected scope
  2. Detect framework (wxWidgets / GTK3 / Qt) from includes and CMakeLists.txt
  3. Match review depth to task complexity (single file vs multi-module)
  4. Validate requirements — does implementation match task scope exactly?
  5. Issue focused feedback with specific file paths and line numbers

Review Strategy

Simple Tasks (single file/widget): Memory safety, framework correctness, requirements match

Complex Tasks (multi-module): Above plus architecture, ownership graph, event flow, thread safety

Always: Check CMakeLists.txt, check for raw pointer leaks

Review Checklist

Memory Safety:

  • No raw new without matching delete (prefer smart pointers)
  • No dangling pointers to destroyed widgets
  • RAII used for all resource acquisition (files, sockets, handles)
  • No reinterpret_cast without safety justification
  • Container access bounds-checked where needed (at() vs [])

Framework Anti-Patterns:

  • wxWidgets: no manual delete of child windows (parent owns them)
  • GTK3: all g_object_unref / g_free calls present
  • Qt: no delete on QObject children (parent-child ownership)
  • No blocking calls in GUI event loop (use async/worker threads)
  • Event handlers do not throw exceptions across framework boundaries

Build System (CMakeLists.txt):

  • Target-based commands (no include_directories(), link_libraries())
  • find_package() with imported targets, not raw variables
  • Minimum CMake version specified
  • No hardcoded paths or platform assumptions without conditionals

Thread Safety:
