ATV-Phoenix 是做什麼的？
Turn a project, GitHub PR, app URL, or evidence path into a polished showcase video, poster, sourced plan, HyperFrames composition brief, manifest, and share copy. Use when asked to show off a project, make a demo video or showcase reel, turn a PR into a video, create a product demo, or produce a shareable clip. Runs inline with host-native tools in GitHub Copilot CLI, VS Code Copilot agent mode, or Claude Code; subagents are optional. Never automatically publishes or uploads finished artifacts.
