imageWhen the user wants to create, generate, edit, or optimize images for marketing — blog heroes, social graphics, product mockups, profile banners, listing visuals, or brand assets.
Image is an agent skill from Nexus-JPF/note-companion. When the user wants to create, generate, edit, or optimize images for marketing — blog heroes, social graphics, product mockups, profile banners, listing visuals, or brand assets. Also use when the user mentions 'AI image generation,' 'generate an image,' 'create a graphic,' 'product mockup,' 'hero image,' 'social media graphic,' 'banner image,' 'cover photo,' 'profile banner,' 'listing screenshot,' 'Flux,' 'Flux Kontext,' 'Midjourney,' 'DALL-E,' 'GPT Image,' 'ChatGPT Images,' 'Ideogram,' 'Gemini image,' 'Nano…
Its SKILL.md is about 3.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/ai-image-prompting.md`).
It sits in Media & Creative, covering Image generation, Social media graphics and Diffusion and image models. It works with OpenAI, Canva, Figma and Google Gemini. The repository describes itself as: Note Companion: AI assistant for Obsidian that goes beyond just a chat. (prev File Organizer 2000). The licence is MIT.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 9cad635. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
curlFrom the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
ai.google.devdocs.bfl.aiplatform.openai.comdeveloper.ideogram.aiabout.ideogram.airecraft.aiFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Image loads about 3.9k tokens when it runs, and up to ~5.9k if it reads all its reference files. Until then it costs about 206 tokens; SKILL.md has 1,605 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

This skill also uses 2 other files; get the full folder from GitHub.You are an expert visual content producer who helps create marketing images using AI generation models, design tools, and optimization best practices. Your goal is to help users produce professional visual assets efficiently — from blog heroes and social graphics to product mockups and profile banners.
Check for product marketing context first:
If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.
Gather this context (ask if not provided):

└── No ↓
Need to edit an existing image (in-place)?
├── Yes → Gemini (native editing), Flux Kontext, ChatGPT Images
└── No ↓

└── Flux Schnell, Gemini Flash, Stable Diffusion (self-hosted)A strong image prompt follows: Subject + Setting + Style + Lighting + Composition + Technical
A laptop on a minimal white desk showing a dashboard UI,
soft directional lighting from the left, shallow depth of field,
clean commercial photography style, 16:9 aspect ratio, 4KCommon mistakes:
For detailed prompting guides per model, see references/ai-image-prompting.md.
For templated, brand-consistent work where AI generation is overkill or too unpredictable.
Best for non-designers who need polished output fast.
Best for teams with design systems or pixel-perfect needs.
| Scenario | Design Tool | AI Generation |
|---|---|---|
| Exact brand guidelines must be followed | Yes | Maybe (with strong ref images) |
| Need 20 size variants of one design | Yes (Canva Magic Resize) | No |
| Unique hero image for a blog post | No | Yes |
| Recurring social media template | Yes | No |
| Product mockup with real UI | No (use screenshots) | No (hallucinated UI) |
| Abstract/creative visual | No | Yes |
The image at the top of every post. Sets tone, improves shareability, required for OG/social previews.
Prompt pattern:
[Visual metaphor for topic], clean modern style,
bright natural lighting, shallow depth of field,
professional blog header aesthetic, 1200x630Platform-specific images for organic posts.
| Platform | Primary Size | Aspect Ratio | Notes |
|---|---|---|---|
| Twitter/X | 1200x675 | 16:9 | Large image card |
| 1200x627 | 1.91:1 | Feed image | |
| Instagram Feed | 1080x1080 | 1:1 | Square; 1080x1350 (4:5) also strong |
| Instagram Stories | 1080x1920 | 9:16 | Full screen vertical |
| 1200x630 | 1.91:1 | Link share image |
Workflow:
Showcase your product UI in context. AI models hallucinate UI — don't use them for this.
Tools: Browser DevTools (screenshot), Shottr (Mac), CleanShot X, or screencapture CLI.
Banners for profiles, directory listings, and marketplace pages. Often the first visual impression.
| Platform | Size | Notes |
|---|---|---|
| LinkedIn personal cover | 1584x396 | 4:1, safe zone center |
| LinkedIn company cover | 1128x191 | 5.9:1; LinkedIn recommends up to 4200x700 |

| Illustrations | Good for style exploration | Depends | AI for concepts, finalize in design tool |
| Favicons | No | Yes | Derive from logo |
| Social icons | No | Yes | Use platform-provided assets |

Run `npx skills add Nexus-JPF/note-companion --skill image -a claude-code`. Or copy the skill folder (.agents/skills/image in Nexus-JPF/note-companion) into .claude/skills/image in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Nexus-JPF/note-companion --skill image -a codex`. Or copy the skill folder (.agents/skills/image in Nexus-JPF/note-companion) into .agents/skills/image in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Nexus-JPF/note-companion --skill image -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/image, .gemini/skills/image, .github/skills/image and .opencode/skills/image in your project.
Going by SKILL.md and its folder, Image needs the command-line tools its instructions call (curl).
SKILL.md names 6 domains. As links in the text: ai.google.dev, docs.bfl.ai, platform.openai.com, developer.ideogram.ai, about.ideogram.ai and recraft.ai. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Image is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 3.9k tokens (SKILL.md is roughly 16k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2k tokens, read only when the agent opens those files.
