qt-qml-profiler

97 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Use when the user is investigating QML / Qt Quick performance — both vague complaints ("the UI feels laggy", "this is slow", "frames are dropping", "the app stutters") and explicit asks to profile, find hotspots, or optimize bindings, signals, or rendering. Runs qmlprofiler on a 2D QML application, parses the .qtd trace, and analyzes hotspots against the source with frame-time, memory, and pixmap-cache summaries. Does NOT cover Qt Quick 3D.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'qt-qml-profiler' ] || [ -L ~/.agents/skills/'qt-qml-profiler' ]; then echo 'A skill folder named qt-qml-profiler already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/TheQtCompanyRnD/agent-skills' "$d" && git -C "$d" checkout --quiet '062f7c9f0e16b7d2f66cd55e449a3ed85fba699e' -- 'skills/qt-qml-profiler' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/qt-qml-profiler' ~/.agents/skills/'qt-qml-profiler' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'qt-qml-profiler' ~/.claude/skills/'qt-qml-profiler' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
