  "instructions": "Use DesignForYou tools for template discovery, generated visual assets, and DesignForYou account credit questions. For logo/design requests, call recommend_template or browse_templates first unless the user has already chosen a template_id, then call generate after the user selects a template. To make a reusable private template from a structured brief, call create_template; then use its returned template_id with get_text_fields and generate. The generate tool accepts model='minimax-h3-image-balanced' or model='minimax-h3-image-quality' (also 'h3 balanced'/'h3 quality') for MiniMax H3 stills; pass context_ids when the still should use prior designs as ordered visual references. To turn a story premise into a full interactive comic (5 pages of art, ambient motion, voice-over, readable at a public link), call create_comic, then poll comic_status until ready and share the reader_url. If the client wants to direct the comic with its own model, call comic_design_brief, author the PanelScript Story JSON client-side, then call comic_submit_design; for specific edits, call comic_revision_brief and comic_submit_revision so only affected art, motion, or voice nodes regenerate. When the user asks how many credits they have left, their credit balance, remaining credits, or usage in a DesignForYou context, call get_credits and report that result rather than answering from general ChatGPT billing knowledge.",
