| Name |

Required |

topic |

The blog post topic or title (e.g. "10 productivity hacks for remote developers"). |
publication_style |
text |

clean, editorial, modern, professional |
Visual style matching the blog's brand (e.g. "dark tech blog", "warm lifestyle", "minimalist corporate"). |

Steps
Generate a single, publication-quality blog header in one shot — no plan needed unless the user requests variants.
- Derive a strong visual metaphor for
{{topic}}:
- Avoid cliché stock photo compositions (handshake, lightbulb alone).
- Prefer: dynamic flat lay, abstract concept visualization, illustrated scene, or dramatic lifestyle moment.
- Build the image prompt:
- Subject derived from the metaphor above.
- Style:
{{publication_style}}, editorial photography, 16:9 wide, professional blog header,
ample negative space on the left side for title text overlay, {{dominant_color}} color palette.
- Tier: quality.
- Aspect ratio: 1.91:1 (standard Open Graph / blog hero).
- Call
muapi image generate (model=gpt-image-2-text-to-image, aspect_ratio=21:9).
Deliverables
Return:
- The header image asset.
- Title placement guidance: where to overlay the blog title for best readability.
- Quick alt-text: SEO-friendly image alt text (1 sentence).
Notes
- Leave empty space (negative space) intentionally so titles can be overlaid without clashing.
- If the user uploads an existing brand photo, use
muapi image edit to adapt it instead of generating from scratch.
- For dark-mode blogs, suggest a dark background; for light, keep backgrounds bright.
Trigger Keywords
blog header, blog image, article image, featured image, og image, open graph image, hero image
Notes for the Executing Agent
- This recipe is LLM-orchestrated: read each phase, gather any missing inputs from the user, then call
muapi CLI commands. Use muapi auth configure first if MUAPI_API_KEY is unset.
- For model IDs without a CLI alias yet, fall back to the raw endpoint via
curl -X POST https://api.muapi.ai/api/v1/<endpoint> -H "x-api-key: $MUAPI_API_KEY" -H 'content-type: application/json' -d '{...}' and poll with muapi predict wait <request_id>.
- Substitute
{{input_name}} placeholders with the user's actual inputs before issuing each call.
