●HANDS

Agents That Work For You

Hands are pre-built autonomous capability packages. Unlike regular agents you chat with, Hands run on schedules, build knowledge graphs, and report results to your dashboard. Activate one and check in on its progress.

Traditional agents wait for you to type. Hands work for you.

Each Hand bundles a HAND.toml manifest, system prompt with multi-phase operational playbook, SKILL.md expert knowledge, configurable settings, and dashboard metrics — all compiled into the binary at build time.

Turns long-form video into viral short clips with captions, thumbnails, and optional AI voice-overs. Publishes to Telegram and WhatsApp.
