Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.
By posit-dev/positron (GitHub) · coding · 4,341 stars · scanned at commit 5d355d4

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/'author-vitest-tests' ~/.claude/skills/'author-vitest-tests' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
