Brag is an agent skill that automatically generates short, shareable launch videos from project repositories with a single command.
The tool solves the problem of creating compelling promotional content for newly built projects. It works by analyzing a project's structure and purpose, then using Claude to craft a narrative arc—deciding the product angle, tone, and which moments to highlight. This story brief is handed to Hyperframes, which handles video composition, timing, and rendering. The output includes the underlying plan, a composition brief, share copy, and a finished MP4 file. Voiceover narration via Kokoro is available as an optional feature.
Brag is designed for developers who want to quickly showcase their work without manual video production. It suits any project that can be visually represented—the tool works by examining what exists in a repository and turning it into a narrative. The skill integrates with multiple agent platforms including Claude Code, opencode, Codex CLI, and any agent supporting custom instructions, making it accessible across different development environments. Installation is straightforward via the skills CLI or by copying the skill directly to an agent's discovery path.
The project maintains active engagement with contributions and feature requests welcomed through issues and pull requests. Development includes careful attention to cross-platform compatibility, with explicit guidance for Windows users regarding symlink configuration and fallback copy procedures. The codebase is organized to support multiple agent discovery mechanisms simultaneously through symlinks, reducing friction for users across different tools.
