dart-language
100 / 100 · Low risk
Fine to try.
Dart 3.x language feature standards: null safety, records, sealed classes, switch pattern matching, extensions, and async/await. Use when using !, ?., ??, late, sealed classes, record types, switch expressions, or async patterns — and before introducing any new Dart 3.x construct to confirm the modern idiomatic approach.
What this skill can do
We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.
Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'dart-language' ] || [ -L ~/.agents/skills/'dart-language' ]; then echo 'A skill folder named dart-language already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/HoangNguyen0403/agent-skills-standard' "$d" && git -C "$d" checkout --quiet '00ca7497a75c323a7e70edaa9beac81cc96c1878' -- 'skills/dart/dart-language' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/dart/dart-language' ~/.agents/skills/'dart-language' && 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/'dart-language' ~/.claude/skills/'dart-language' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
