media-genlisted

Photoreal image + video generation and upscaling via fal.ai (pay-per-use, one API key, always-current models: Kling, Seedance, FLUX, nano-banana Pro, Topaz). Use for image-to-video ("animate this image", "turn this photo into a video"), photoreal video clips for websites/demos, hero video loops, upscaling images/video, or any gen-media need beyond simple local generation. Rewrites rough prompts into model-optimized ones, routes to the cheapest model that fits, saves outputs locally. NOT for code-rendered motion graphics or scroll-driven cinematic flythroughs — that needs dedicated tooling this plugin doesn't ship. For simple illustrations/UI imagery, a separate Gemini-based image skill (if the user has one installed) is usually cheaper — reach for media-gen when a named fal.ai model, image-to-video, photoreal quality, or upscaling is actually needed. ("nano-banana Pro" below is a fal.ai model slug, unrelated to any separately-installed nano-banana skill.)

# media-gen — fal.ai cost-router One fal.ai key covers every current image/video model, pay-per-use — no subscription, no monthly minimum. You prepay credit on fal.ai's dashboard and each request draws down from it: **spend is real money — be surgical.** ## Auth Read the key from the environment first; fall back to the hub's `.env` (the `/jarvis-setup` page's Media section writes it there). The hub itself resolves the same way the SessionStart hook does: `JARVIS_HUB` env var first, else the pointer file at `~/.jarvis-hub-path` written by `/jarvis-setup`, else `~/jarvis-hub`. Never hardcode a path to it and never echo/print/log the value: ```bash hub="${JARVIS_HUB:-$(cat ~/.jarvis-hub-path 2>/dev/null)}" hub="${hub:-$HOME/jarvis-hub}" FAL_KEY="${FAL_KEY:-$(grep '^FAL_KEY=' "$hub/.env" 2>/dev/null | cut -d= -f2-)}" ``` If `FAL_KEY` is still empty after that, stop and tell the user to add it via `/jarvis-setup` — do not hunt for it elsewhere. Every request: header `Authorization: Key $FAL_KEY`. ## Cost discipline (the point of this skill) - **Images are cheap** (fractions of a cent). Iterate freely. - **Video bills per second.** Default 3–5s, never more without an explicit ask. 5s vs 10s = real dollars. State the model + estimated cost BEFORE a video run and get the user's go-ahead unless they already gave one this session. - Cheapest-fit routing: draft/test → FLUX schnell; final image → FLUX dev or nano-banana Pro; image→video → Kling (best value) before Seedance (
