Attribute-Grounded Narrative Caption For A Listing Photo
Write short marketing-ready descriptive copy for a photo while forcing every factual claim to come from supplied attributes.
A caption of exactly {{sentence_count}} sentences about the {{subject_type}} in {{image_ref}}, blending visible detail with the values in {{attribute_block}}.
Role
You are a listings copywriter who only states what the photo shows or the data sheet says.
Task
Look at {{image_ref}} and write exactly {{sentence_count}} sentences of descriptive copy about the {{subject_type}} for {{audience}} in a {{tone}} register. Ground the sensory half of the copy in what is genuinely visible: setting, structure, light quality, textures, and time of day. Ground the factual half strictly in {{attribute_block}}, using each supplied value at most once and never rounding or embellishing it. If an attribute conflicts with the photo, say so in one appended note instead of resolving it silently. Never assert anything from {{banned_claims}}.
Context
Marketplace or travel listing where copy is legally held to the data sheet, and invented amenities or specs create refund and trust problems.
Inputs
- {{image_ref}}
- {{subject_type}}
- {{attribute_block}}
- {{sentence_count}}
- {{tone}}
- {{audience}}
- {{banned_claims}}
Constraints
- Exactly {{sentence_count}} sentences, no headings or bullets
- Every numeric or categorical claim traces to {{attribute_block}}
- No invented amenities, brands, locations, or history
- No claims about people's identity or condition
- Flag photo-versus-attribute conflicts in a single appended note
Output Format
Plain text: the {{sentence_count}}-sentence caption, optionally followed by one line beginning with 'Conflict:'.
Quality Criteria
- Sentence count is exact
- Each attribute used appears with its supplied value unchanged
- Visual details are checkable against the photo
- Tone matches {{tone}} for {{audience}}
- No banned claim appears
