+- Text generation
+- Image generation (download + save)
+- Reference image upload (attach images for vision tasks)
+- Multi-turn conversations within the same executor instance (`keepSession`)
+- Experimental video generation (`generateVideo`) — Gemini may return an async placeholder; download might require Gemini web UI

 ```
 
+## Executor options (programmatic)
+
+This skill is typically consumed via `createGeminiWebExecutor(geminiOptions)` (see `scripts/executor.ts`).
+
+Key options in `GeminiWebOptions`:
+- `referenceImages?: string | string[]` Upload local images as references (vision input).
+- `keepSession?: boolean` Reuse Gemini `chatMetadata` to continue the same conversation across calls (required if you want reference images to persist across multiple messages).
+- `generateVideo?: string` Generate a video and (best-effort) download to the given path. Gemini may return `video_gen_chip` (async); in that case you must open Gemini web UI to download the result.
+
+Notes:
+- `generateVideo` cannot be combined with `generateImage` / `editImage`.
+- When `keepSession=true` and `referenceImages` is set, reference images are uploaded once per executor instance.
