description	Generates an on-brand marketing graphic — hero image, ad creative, background, or texture — with an image model, optionally stamped with the brand logo and a caption. Opt-in: needs a provider key and network access. Use when a user wants a photographic or illustrative graphic, not a text-heavy asset. Trigger with "make a hero image", "ad background", or "/brand-make graphic".

Generate Graphic

Generates an on-brand marketing graphic through an image model — the one opt-in feature that reaches the network — optionally stamped with the brand logo and a caption.

Overview

The generate-graphic skill is the opt-in raster engine. Everything else in brand-forge (logos, social, docs) stays vector and zero-permission; this skill is the only path that calls an external image provider, so it runs only when a user explicitly wants a photographic or illustrative graphic. The generator builds a brand-aware prompt with lib/raster.mjs, calls the provider with lib/genimage.mjs, and can composite a crisp vector logo and caption over the result with lib/composite.mjs. Text is deliberately kept out of the image and added as vector on top.

Prerequisites

• An active brand profile created with /brand-new. Read loads its color-system.json, typography.json, and visual-identity.md.
• Two opt-in signals, both required: BRAND_FORGE_RASTER=1 and a provider key (GEMINI_API_KEY by default, or OPENAI_API_KEY). The 30-preflight emitter surfaces this at session start.
• Authentication: the provider api key is read from that environment variable and sent as a request header, never placed in the URL. No credentials are written to disk.
• Node.js on the PATH and Write access to an output/ directory.

Instructions

1. Verify both opt-in signals are set. If either is missing, stop, explain how to enable raster, and offer the vector path (generate-social or a template) instead, which needs neither.

2. Use Glob to locate the active brand directory, then Read and validate the profile with validateProfile.

3. Build the prompt with lib/raster.mjs (no network). It encodes the palette in words, the imagery style, and the tone, and turns the brand's don't-rules into an "Avoid:" clause. Warn the user when literal text is requested and route text-heavy work to the vector engine.

   import { loadProfile } from '../../lib/brand.mjs';
   import { buildRasterPrompt } from '../../lib/raster.mjs';
   const profile = (activeDir);
    prompt = (profile, { :  });
