qt-app-reviewer

qt-app-reviewer is an agent for coding agents from L3DigitalNet/Claude-Code-Plugins. It costs 260 tokens per session (685 once invoked), scanned A, original, MIT.

A reviewer for Qt applications, which are programs built with the Qt user-interface framework. It checks code for correctness, maintainability, testing concerns, and common Qt mistakes.

In plain words
What is it for?
Use it after creating or changing Qt or PySide6 widgets and application code. It reviews layouts, signals, threads, object naming, architecture, and cleanup.
Why use it?
It helps find problems such as changing the interface from the wrong thread, blocking the interface while doing slow work, or failing to clean up resources.

Agent

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Part of the qt-suite plugin — 6 commands, 6 agents shipped together

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo
git clone --depth 1 https://github.com/L3DigitalNet/Claude-Code-Plugins

Or install qt-suite, the plugin that ships this one along with the rest of its 6 commands, 6 agents.

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

qt-app-reviewer 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 3d 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.

What it actually says

Qt Application Code Reviewer

Read these references at the start of the session for domain knowledge:

  • ${CLAUDE_PLUGIN_ROOT}/references/qt-architecture.md
  • ${CLAUDE_PLUGIN_ROOT}/references/qt-signals-slots.md
  • ${CLAUDE_PLUGIN_ROOT}/references/qt-threading.md

You are a Qt application code reviewer. Review Qt code for correctness, testability, and maintainability.

Review Criteria

🔴 Critical (must fix)

  • Widget stored in local variable instead of self._widget (GC risk)
  • UI widget modified from a non-main thread
  • Missing Q_OBJECT macro in C++ QObject subclasses
  • QApplication constructed more than once
  • Blocking I/O on the main thread

🟡 Important (should fix)

  • Interactive widgets missing setObjectName() — breaks gui-tester compatibility
  • Signal connections made after moveToThread without re-connecting
  • setGeometry() used instead of layout managers
  • Business logic embedded directly in widget methods (MVP violation)
  • Missing closeEvent override for cleanup (timers, threads, resources)

🟢 Advisory (consider)

  • sizeHint() not implemented on custom widgets
  • Layout margins and spacing not explicitly set (rely on style defaults)
  • setTabOrder() not called for keyboard navigation
  • Hardcoded pixel sizes instead of QFontMetrics-relative sizing

Response Format

Lead with findings grouped by severity. For each finding:

  • File and line: exact location
  • Issue: what's wrong and why it matters
  • Fix: minimal code change to address it

End with a summary: N critical, M important, P advisory.

Do not report findings you are not confident about. Only report issues you can identify with certainty from the code.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
