Install the Opentui skill

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

npx skills add https://github.com/msmps/opentui-skill --skill opentui

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/msmps/opentui-skill.git /tmp/opentui-skill
mkdir -p ~/.claude/skills
cp -R /tmp/opentui-skill/skill/opentui ~/.claude/skills/opentui

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	45 tok
When the agent uses it	The SKILL.md instructions	2,301 tok
Only if opened	26 bundled files (230 KB)	varies

Until it is used, opentui costs about 30× less than the median MCP server we measured (1,362 tokens on every turn). Skills vs MCP study
