Installation

Quick Install (all agents)

npx @eigent-ai/agent-skills install

This auto-detects installed agents (Claude Code, Cursor, Windsurf, Codex, Copilot) and installs skills to each.

Install specific skills only

npx @eigent-ai/agent-skills install mintlify-docs-updater
npx @eigent-ai/agent-skills install mintlify-docs-updater webapp-testing

Use npx @eigent-ai/agent-skills list to see all available skills.

Install for a specific agent

npx @eigent-ai/agent-skills install -a claude-code
npx @eigent-ai/agent-skills install -a cursor mintlify-docs-updater

Install globally (user-level)

npx @eigent-ai/agent-skills install -g

Via the Skills ecosystem

npx skills add eigent-ai/agent-skills

Updating

Pull the latest skills from GitHub:

npx @eigent-ai/agent-skills update

The CLI tracks a content hash so it only writes when there are actual changes.

Auto-update

Set up scheduled updates with a cron job:

npx @eigent-ai/agent-skills auto-update              # weekly (default)
npx @eigent-ai/agent-skills auto-update --interval daily

This prints the cron line to add to your crontab.

CLI Reference

Command	Description
install [skill...]	Install all skills (or specific skills) to detected agents
update	Fetch latest from GitHub and update
uninstall [skill...]	Remove all or specific installed skills
