Install the Email Marketing skill

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

npx skills add https://github.com/nexu-io/html-anything --skill email-marketing

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/email-marketing ~/.claude/skills/email-marketing

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.

What it costs your context

Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.

When	What loads	Cost
Every session	Name and description	23 tok
When the agent uses it	The SKILL.md instructions	126 tok
Only if opened	1 bundled files (10 KB)	varies

Until it is used, email-marketing costs about 59× 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.
