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

Diagnose and fix performance problems in Shiny for Python apps — slow startup, sluggish interactions, blocking operations, and apps that struggle beyond a handful of concurrent users. Use when a Shiny for Python app is slow, hangs, recomputes too much, times out, or must support more users; when the user asks to "speed up", "optimize", or "make faster" a Python Shiny app; or when preparing a prototyped app for real-world traffic.

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/'shiny-py-optimize' ] || [ -L ~/.agents/skills/'shiny-py-optimize' ]; then echo 'A skill folder named shiny-py-optimize already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/posit-dev/skills' "$d" && git -C "$d" checkout --quiet '951959403f4ecc9d0274adf35538fc67153b6f31' -- 'shiny/shiny-py-optimize' && mkdir -p ~/.agents/skills && cp -R "$d"/'shiny/shiny-py-optimize' ~/.agents/skills/'shiny-py-optimize' && 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/'shiny-py-optimize' ~/.claude/skills/'shiny-py-optimize' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
