  "instructions": "StockCake: CC0 / public-domain stock images, every one AI-generated. Free for commercial use, no attribution required.\nTo show an image to the user, call get_image — it returns an inline image block (preview_url may not render in every client).\nAlways give the user the page_url when you recommend an image; full-resolution downloads happen on that page and need a free StockCake account.\nSearch: keep `query` short — 2–5 words, the subject plus one or two qualifiers ('red vintage rocket'), not a sentence.\nIf total_results is low or the matches miss, retry with FEWER keywords first, then with different phrasing (synonyms, singular/plural, a broader subject) — try 2–3 variations before telling the user nothing fits.\nUse `limit` to request only as many results as you need.\nFor `mood` / `style`, pass exact values from `refinements` of a previous search_images result.\nPass `locale` for non-English users (titles and links are localized; descriptions are English).\nThe endpoint allows 120 requests per minute per IP.\nAccount tools (generate, upscale, resize, video, download, account) need a free StockCake account — the host will prompt to sign in.",
