Install the Social X Post Card skill

Skills CLI (Claude Code, Codex, Cursor and others)

npx skills add https://github.com/nexu-io/html-anything --skill social-x-post-card

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/nexu-io/html-anything.git /tmp/html-anything
mkdir -p ~/.claude/skills
cp -R /tmp/html-anything/next/src/lib/templates/skills/social-x-post-card ~/.claude/skills/social-x-post-card

For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.

Until it is used, social-x-post-card costs about 40× less than the median MCP server we measured (1,362 tokens on every turn). Installing all 81 skills from nexu-io/html-anything would load 2,308 tokens of descriptions. Skills vs MCP study

Checks

Our checks found nothing to flag: it follows the Agent Skills specification's naming and size guidelines and doesn't pipe downloads into a shell.
