Logo Maker

Logo generator. Input: brand name + optional tagline + style preset + palette hint. Output: N stochastic variants of the same brief.

Distinct from cover-maker:

• No artist / author / medium fields — just brand
• Single image (no aspect variants — logos work the same at all sizes by design)
• Different model bias: ideogram-3-quality is the default (best embedded text rendering)
• Aesthetic conventions: clean, geometric, often single-color, isolated on background

Distinct from flyer-maker:

• No event details — logos are timeless brand artifacts, not event-specific
• No multi-aspect — same mark serves all platforms
• Very minimal composition (logo dominates frame; no headline blocks)

This skill does NOT:

• Generate full brand books (typography systems, color tokens, voice guidelines) — single mark image only
• Vectorize the output to SVG — that's a separate step (open the PNG in Vectornator / Illustrator / Affinity Designer + auto-trace)
• Guarantee trademarkability — outputs may resemble existing marks; check with a trademark search before commercial use
• Remove the background — chain with bg-remover if you need transparent PNG

ROLE

Read brand + style preset + palette → pick text-strong model → assemble variant prompts that strongly cue "logo isolated on white background, no shadows, vector aesthetic" → batch execute → save PNGs.

PIPELINE

1. Resolve brand:

• Required: --brand ""
• Optional: --tagline ""

1. Resolve style preset — see references/style-presets.md:

• --style wordmark — pure typography, no icon (default if brand name ≤2 words)
• --style minimal — geometric mark + optional brand name
• --style illustrated — pictorial / mascot
• --style typographic — custom lettering, ornamental type
• --style geometric — angular / parametric (Bauhaus-like)
• --style emblem — badge / seal / circular composition

1. Palette hint (optional but recommended):

• --palette "two tones, deep teal + warm cream" — natural-language palette description
• Defaults to "monochrome black on white" when omitted

1. Pick model:

• Default: ideogram-3-quality — cleanest text rendering in image-gen, perfect for wordmarks
• Fallback: gpt-image-2 — better for illustrated + emblem styles with subtle text
• Override: --model

1. Compose ONE LLM call — load [common/visual-prompt-library/system-prompt.md](../../common/visual-prompt-library/system-prompt.md) (shared SYSTEM_PROMPT) and buildUserMessage(opts) with Mode=logo, N=, brand + tagline + style preset + palette. Spawn ONE Agent. Receives JSON {"slides":[{"number":1,"prompt":"..."}]} — 1–3 sentence prompts cueing isolated-on-white, no background clutter, vector look. Brand name in double quotes. The N prompts share the same content brief but allow stochastic variation in execution (different geometric interpretations, different palette emphasis within the constraint).

1. Estimate cost + confirm — inherits SKILLS_CAROUSEL_BUDGET=1.50.

1. Batch execute — common.runners.batch.run_batch().

1. Output:

`` ./generated/logo// logo-v1.png logo-v2.png logo-v3.png (if --variants 3) manifest.json prompts.md ``

MODES

Required

• logo-maker --brand ""

Optional content

• --tagline "" — secondary text (e.g., "since 2024", "engineered minds")
• --palette "" — natural-language palette description
• --lang en|ru — language hint (default: auto-detect)

Visual

• --style wordmark|minimal|illustrated|typographic|geometric|emblem — default wordmark
• --style-mod "" — append tweak (e.g., "with a single accent dot in orange")
• --variants N — variants (default 4 — logos benefit from more options)
• --model auto| — image provider

Execution

• --execute — actually generate
• --output — custom output
• --parallelism N — concurrent calls (default 2)
• --yes — skip cost confirmation
• --resume — retry failed
• --prompts-only — dry run

STRUCTURED LAYOUT (Ideogram 4 only)

When --model is an ideogram-4* tier, emit the layout as structure instead of flattening it into a sentence: add json_prompt to each plan item's kwargs, following [common/references/json-prompt.md](../../common/references/json-prompt.md). This skill already knows where every element goes; sending that directly is what stops the arrangement drifting between variants.

On any v3 tier the provider refuses a json_prompt rather than ignoring it, so keep the prose prompt as written and send nothing extra.

REFERENCES (load on demand)

| File | When to load | |---|---| | [references/style-presets.md](references/style-presets.md) | Step 2 — exact composition rules per preset, when to pick which, common mistakes | | [references/model-picker.md](references/model-picker.md) | Step 4 — which model handles which style best, text vs icon strengths | | [references/troubleshoot.md](references/troubleshoot.md) | When text gets garbled, icon looks generic, palette ignored |

EXAMPLES

See [examples/before-after.md](examples/before-after.md) — 3 calibration runs: SaaS wordmark, illustrated mascot, geometric emblem.

CONSTRAINTS

• Brand name ≤3 words for best wordmark rendering. Past 3 words, switch to abbreviation or acronym.

• Pick ONE style preset per run. Don't mix wordmark + illustrated in the same batch — variants should explore one direction at a time.

• More variants = better selection. Default 4 (vs 2 for cover-maker) because logo selection is inherently subjective.

• Default to embedded-text-strong model. ideogram-3-quality is the default for a reason — text rendering breaks 90% of generated logos.

• Vector workflow is a separate step. Output is raster (PNG). To get SVG: pick best variant → open in Illustrator/Affinity Designer/Vectornator → auto-trace → manually clean up.

• Isolation hint is built into the prompt. All variants cue "isolated on white background, no shadows, no environment". To get transparent PNG: chain with bg-remover.

• No multi-aspect output. A logo works the same across all aspects; produce ONE mark, scale as needed in your design tool.

• Cost confirm ONCE per batch. Sum across variants.

• Trademark check is YOUR responsibility. The skill cannot verify uniqueness — run a trademark search before commercial use.

• Never print API keys. Mask in errors.

INVOCATION HINTS

When the user says any of:

• "design a logo for X", "logo for my brand", "create a wordmark"
• "brand mark", "company emblem", "monogram"
• "логотип", "сделай лого", "фирменный знак", "эмблема", "брендовый знак"

If the user mentions a domain (SaaS, restaurant, agency), bias --style accordingly:

• SaaS / tech → wordmark or geometric
• Restaurant / artisan → illustrated or emblem
• Editorial / studio → typographic
• Personal brand → wordmark with --style-mod "elegant"

Defaults: --style wordmark --variants 4 --model ideogram-3-quality. Without --execute, returns prompts.

This skill is distinct from:

• cover-maker — albums/books/podcasts. This is brand identity.
• flyer-maker — events. This is timeless brand.
• thumbnail-maker — content marketing. This is brand identity.
• image-prompt — free-form. This is structured logo conventions with strong text-rendering bias.
