coding-guidance-qt

coding-guidance-qt is a skill for Claude Code, Codex from n-n-code/n-n-code-skills. It costs 67 tokens per session (2,836 once invoked), scanned A, original, MIT.

Coding and review guidance for Qt applications written in C++, including desktop windows, forms, data models, events, threads, and build tools.

In plain words
What is it for?
Use it when building or reviewing Qt 5 or Qt 6 desktop software, especially QWidget interfaces, dialogs, model-view code, signals and slots, or Qt builds.
Why use it?
It helps avoid common Qt problems involving object lifetimes, event connections, thread ownership, user-interface behavior, and compatibility between Qt versions.

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

coding-guidance-qt 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 257 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Qt Coding Guidance

This skill adds portable Qt implementation, refactoring, and review guidance for Qt C++ code with a QWidget desktop focus. Widget, dialog, model/view, Designer, and desktop-UX guidance here is specific to Widgets work; broader QObject, threading, and build guidance also applies to non-UI Qt C++ code.

Adjacent Skills

This skill provides portable Qt engineering principles. Compose with:

  • Workflow: thinking (ambiguous decision framing), recursive-thinking (stress-testing), security (threat modeling)
  • Domain overlays: ui-guidance (ordinary graphical UI work), ui-design-guidance (stronger design and UX work), project-core-dev (repo-specific completion discovery and reporting when needed), project-platform-diagnose (environment-sensitive diagnosis)

Use this as the default principle skill for Qt code. Reach for coding-guidance-cpp only when the task is mostly non-Qt C++ or needs deeper general C++ design judgment than Qt-specific guidance.

Quick Routing

Open bundled references only when the task actually needs them:

Stay in the main skill when the task is broad Qt implementation or review and no single failure mode dominates yet.

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.
