Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.
By wjgoarxiv/litgravity (GitHub) · coding · 167 stars · scanned at commit 53899d5
Make a .pptx slide deck from a request or sources in a chosen design direction, gate it mechanically, then look at every rendered page. Needs Python 3.10+.
Works with any agent that supports SKILL.md skills.

Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'lit-pptx' ] || [ -L ~/.agents/skills/'lit-pptx' ]; then echo 'A skill folder named lit-pptx already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/wjgoarxiv/litgravity' "$d" && git -C "$d" checkout --quiet '53899d5885b11bc5b687f17c21aae0e380549874' -- 'plugin/skills/lit-pptx' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugin/skills/lit-pptx' ~/.agents/skills/'lit-pptx' && 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/'lit-pptx' ~/.claude/skills/'lit-pptx' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
