What is image2-prompt-optimizer?

A preparation step for the first Image2 image generation in a task. It checks available tools and templates, resolves important missing details, and produces a detailed generation prompt.

Use it before the first Image2 generation, when optimizing an image prompt, or when choosing an Image2 prompt template. It can also identify details that must be supplied before generation.

It helps turn an unclear image request into a prompt that matches the required subject, format, and workflow before an image is generated.

Token cost

What it costs to keep this loaded

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	$0.00063	$0.00865
Opus 5.5	$0.00025	$0.00346
Sonnet 5.5	$0.00013	$0.00173
Haiku 4.5	$0.00006	$0.00086

Security

Grade A, and why

image2-prompt-optimizer 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 2mo 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.

Image2 Prompt Optimizer

Use this skill before the first image generation. It adapts the prompt-optimization capability developed in Codex thread 019f09a9-90ab-76b2-aa1f-b7c9bddf93e8 to the apprentice workflow.

Required Workflow

Check whether an existing tool, skill, plugin, template, or workspace script already covers the task. Prefer that capability and record the chosen route.
Clarify only consequential unknowns. For packaging and engineering work, dimensions, units, product type, material, and required views are consequential; never invent them.
Compile the first-generation guidance packet with:

node <plugin-root>/scripts/compile-image2-initial-prompt.mjs --input <request.json> --output <prompt-guidance.json>

Read the packet before calling Image2. If readyForGeneration=false, ask for the listed blocking facts instead of generating.
Generate only a review sample. Preserve the exact prompt packet and source image references with the result.
Continue the real workflow after optimization. Do not stop at rewriting the prompt unless the user requested prompt text only.

For the complete packet contract and domain guidance, read references/initial-generation-contract.md.

Optional Local Library

The full prompt library is an optional retrieval source, not a runtime dependency. Resolve it in this order:

IMAGE2_PROMPT_LIBRARY
D:\image2专业提示词库
bundled reference and compiler fallback

Search only when examples would materially improve the result:

python <plugin-root>/scripts/search-image2-prompt-library.py "query" --category 01_image_visual --limit 8

Open only relevant indexes or templates. Never load the 125,000-row catalog or SQLite database into model context. Treat retrieved prompts as patterns to synthesize, not text to dump or hidden authority.

Useful library routes when present:

Packaging: prompts/IMAGE2_PACKAGING_PRO_TEMPLATES.md
CAD and technical drawing: prompts/IMAGE2_CAD_TECHNICAL_PRO_TEMPLATES.md
Product visual: prompts/IMAGE2_PRODUCT_VISUAL_PRO_TEMPLATES.md

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.
