HappyHorse
Text, image, and edit-video generation with 720p and 1080p output, duration control, first-frame image support, ordered reference images for character-guided clips, and source-video editing.
# Works with Claude Code, Codex, Gemini CLI, Cursor, and 50+ agents
npx skills add runapi-ai/happyhorse -gInstall the HappyHorse skill for me: 1. Clone https://github.com/runapi-ai/happyhorse 2. Copy the skills/happyhorse/ directory into your user-level skills directory (e.g. ~/.claude/skills/ for Claude Code, ~/.codex/skills/ for Codex). 3. Verify that SKILL.md is present. 4. Confirm the install path when done.
HappyHorse creates text, image, and edit-video clips with selectable 720p or 1080p output, deterministic seed control, first-frame image guidance, ordered reference-image guidance for the character model, and source-video edit instructions.
