Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00109 | $0.00990 |
| Opus 5 | $0.00055 | $0.00495 |
| Sonnet 5 | $0.00022 | $0.00198 |
| Haiku 4.5 | $0.00011 | $0.00099 |
Grade A, and why
seo-image-gen scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
seo-image-gen
Family: seo Status: Stable
Purpose
The generation half of image SEO (split from the audit because it carries different legal/asset/API risk). Produces images at correct dimensions with SEO-aware presets, file naming, and suggested alt text. It is tool-aware: it renders through whatever generator you have — preferring the Gemini CLI — and, when no generator is available, still delivers production-ready prompts + exact specs + filenames + alt text so you can generate elsewhere. That prompts-and-specs output is real value on its own; it never just fails.
Triggers
- "generate image" / "create a visual"
- "og image" / "social preview"
- "hero image" / "blog image"
- "product photo" / "infographic" / "favicon"
Inputs
- Subject/prompt and brand context (palette, style — pull from a design system)
- Preset: og | hero | product | infographic | favicon
- Output path (in the user's project workspace)
Steps
- Pick the preset and resolve its spec — e.g. OG 1200×630; hero ~1600×900;
favicon set (16/32/180/512). Pull palette/style from a
design-system-genresult so generated images match the brand. - Compose the generation prompt — subject + style + palette + composition, with negative prompts to avoid unwanted text artifacts.
- Detect generators. Run
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/workflow/capability_probe.py"and check for a connected image-gen MCP. Route per the cascade below. - Generate or hand off. If a generator is available, render at the preset dimensions into the user's workspace. If none is, output the prompt + exact specs and stop with a one-line note on how to enable rendering (install the Gemini CLI or connect an image-gen MCP/provider key).
- Name + alt. SEO-friendly filename (kebab-case, descriptive) + suggested alt text per image.
- Hand to
seo-image-auditto verify generated assets pass the audit.
Capability routing
This skill follows the plugin's capability-tier cascade
(references/CAPABILITY-TIERS.md). For image generation there is no built-in Claude
renderer, so the numbers run 3 → 1 → 4 by design (the CLI is preferred over an MCP):
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

seo-image-gen is a skill published in the GitHub repository ZachArticulateV/designer-pro-and-seo (8 stars, last pushed 2mo ago), licensed MIT. It adds 109 tokens to every session and 990 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
