Key takeaways
- Logic's described workflow moves from a human moodboard to a formal specification, framing translation of aesthetic intuition into a precise schema as the primary challenge.
- Logic generated the guide's editorial image series by keeping the schema constant and changing only the scene block, and the document reports that the resulting images read as a coherent set when viewed together.
- The document asserts that even detailed prompts can produce inconsistent images across runs because models probabilistically infer unstated details, causing drift in color, composition, and lighting.
- Logic rebranded and published a flagship guide on how to build an AI agent.
- The document asserts that prose-based image prompting tends to yield generic, average-looking results even when describing a plausible scene.

Schema-Driven Control As A Translation Of Taste Into Machine-Readable Constraints
- Logic's described workflow moves from a human moodboard to a formal specification, framing translation of aesthetic intuition into a precise schema as the primary challenge.
- Logic asked a model to convert moodboard-derived aesthetic data into a schema that the model itself could use to generate related images.
- The document asserts that structured specifications outperform prose prompts by decomposing vague style labels into explicit subcomponents, reducing what the model must guess.
- The document asserts that quantified constraints (such as explicit counts and defined color roles) produce more coherent image generations than qualitative wording.
- The document claims that current LLMs lack taste but can interpret strict instructions and structured formats such as JSON effectively.
- The document asserts that this schema approach works because the vocabulary used by the model to describe visual qualities is also the vocabulary it follows when generating images.
Operational Workflow: Forbidden Lists, Reusable Style Capsules, And Separation Of Invariant Style From Variable Scene
- Logic generated the guide's editorial image series by keeping the schema constant and changing only the scene block, and the document reports that the resulting images read as a coherent set when viewed together.
- Logic iteratively tuned generations and maintained a forbidden list to eliminate recurring aesthetic failures such as glossiness and neon coloration.
- After several iterations, Logic produced a reusable style capsule intended to encode its taste and make outputs resemble a design system rather than an approximation.
- Logic built a schema called CBS (Comprehensive Brand Styles) intended to freeze style while allowing scene content to vary.
- CBS is described as organizing image generation into immutable identity/style blocks (including forbidden elements) plus a variable scene block that defines the concept.
- Logic's style capsule includes explicit analog-collage cues such as mixed-media medium, film grain, paper creases, washed blacks, matte finish, clean cut-paper edges, and crisp long shadows to avoid a synthetic look.
Failure Modes Of Prose Prompting And Run-To-Run Inconsistency
- The document asserts that even detailed prompts can produce inconsistent images across runs because models probabilistically infer unstated details, causing drift in color, composition, and lighting.
- The document asserts that prose-based image prompting tends to yield generic, average-looking results even when describing a plausible scene.
- The document asserts that image models gravitate toward a slick, hyper-saturated average aesthetic unless constrained, and that the schema is intended to counteract this pull.
Brand-Driven Requirement For Cohesive Editorial Imagery
- Logic rebranded and published a flagship guide on how to build an AI agent.
- Logic wanted a cohesive, curated editorial image series for the guide rather than using stock photos or generic gradients.
Unknowns
- Which image model(s), versions, and generation settings (seed, guidance, steps, resolution) were used to produce the editorial image series?
- What is the exact representation of CBS and the style capsule (fields, allowed values, validators), and how are constraints enforced in the generation toolchain?
- How much iteration was required (number of cycles, time, cost), and what parts were automated versus manual (including creation of the forbidden list)?
- What objective metrics or evaluation rubric (if any) were used to judge 'cohesion' and 'intentional' look, beyond subjective review?
- How well does the approach generalize to other brands, styles, or content types (product UI imagery, photography-like art, 3D renders), and what are known failure cases?
