explainer

/pika:explainer

Generate a ~60–80s URL explainer video: drive a real browser through the URL along a beat-sheet timeline, generate an avatar lipsync of the narration, and composite it all in a 1280×800 macOS Sonoma frame with a 240-pixel inner avatar (246-pixel outer including 3px white stroke ring) at canvas (20, 476) and element-targeted zoom on every mid-section beat. Works on any URL — product pages, docs sites, blog posts, launches. GitHub URLs activate a repo-aware mode (README scan + live-demo detection); all other URLs use a generic page-walkthrough flow.

Usage: /pika:explainer <url> [--focus "angles"] [--avatar <url>] [--voice <id>] [--lipsync-provider pika|kling] [--preview] [--live-url <url>]

Cost transparency gate

Before any paid MCP call, call identity_balance({verbose: true}) once. Surface the current balance, recent burn rate, and remaining runway, then gate the run with this exact message:

Estimated cost: about 50-500 credits (~$0.50-$5.00) depending on lipsync provider, narration, captions, and preview mode. This can reach $5, so Reply proceed to continue or cancel to stop.

Do not call any paid MCP tool until the user replies proceed. If the user replies cancel, stop without generating. The gate runs after the URL and optional flags are known, before avatar generation, speech, lipsync, captions, or video composition.

Behavior

Defaults — fire fast, no unnecessary mid-flow confirmation
