Fine to try.

By siesdart/jaspr-portfolio (GitHub) · data · 13 stars · scanned at commit 628e1cb

Applies Dart 3 pattern matching, switch expressions, and destructuring idiomatically to validate data schemas, handle algebraic data types, and decompose control flow. Use when refactoring complex if-else chains, parsing polymorphic JSON or API responses, destructuring Lists, URI/path segments, String.split() tokens, Records, or Maps, or enforcing exhaustiveness on sealed classes. Don't use for simple boolean conditions, single-variable type promotion (use `is`), or basic collection filtering.

Works with any agent that supports SKILL.md skills.

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-use-pattern-matching' ] || [ -L ~/.agents/skills/'dart-use-pattern-matching' ]; then echo 'A skill folder named dart-use-pattern-matching already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/siesdart/jaspr-portfolio' "$d" && git -C "$d" checkout --quiet '628e1cbb781c3f70563de90adf3d9f76473f06dd' -- '.agents/skills/dart-use-pattern-matching' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/dart-use-pattern-matching' ~/.agents/skills/'dart-use-pattern-matching' && 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-use-pattern-matching' ~/.claude/skills/'dart-use-pattern-matching' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
