jc-gpt-image

name	jc-gpt-image
description	Use when a user asks to generate or edit an image with GPT Image 2, including text-to-image, reference-image editing, posters, typography, UI mockups, or diagrams.
compatibility	Requires Python 3.11+ and either `gpt-image`, `uv`, or `uvx`. CLI/API calls read `OPENAI_API_KEY` and may incur OpenAI API charges.

gpt-image

Agent runbook for GPT Image 2 generation/editing. Use the prompt library + packaged CLI. Do not reimplement image API code.

Operating loop

0. 🔑 Key check (ALWAYS FIRST): Before ANY image operation, check if OPENAI_API_KEY is configured.

   • Check both process env (echo $OPENAI_API_KEY) and ~/.env file.
   • If key is missing → immediately ask user via interactive dialog with two questions:
     1. "API Key" (password field) — their NewAPI key
     2. "API Base URL" (text field, default: https://api.jiucaihezi.studio/v1)
   • After user submits, write OPENAI_BASE_URL=... and OPENAI_API_KEY=... to ~/.env. The CLI reads this file automatically. User never touches terminal.
   • If key exists → skip to step 1.

1. Classify request: generate, edit, inpaint, or multi-reference; identify asset type, exact text, aspect ratio, references, safety constraints, and budget/quality.

2. Search references first: open references/gallery.md; load/search the closest references/gallery-<category>.md file(s). Read actual **Prompt** text before choosing a pattern.

3. Refine with craft: load references/craft.md for dense text, diagrams, UI, data visualization, multi-panel layouts, weak prompts, or no close gallery match.

4. Confer when useful: before costly/ambiguous/high-polish calls, present 1–3 matched directions plus planned size/quality; ask at most one concise question. Skip long discussion for precise “generate now” requests.

5. Preflight, no side effects: use existing CLI/skill if present. Check command availability (command -v gpt-image), installed tool lists when the tool manager exists, or the runtime’s own skill registry when available. Do not assume a local home path in cloud/hosted runtimes.

6. No blind setup: do not reinstall, overwrite skill folders, create/modify .env, or write API keys unless the user explicitly requested setup. Global/shared installs are opt-in only.

7. Execute via CLI only: call gpt-image or scripts/generate.py. Do not create a new generate.py, SDK wrapper, or ad-hoc script for normal image requests.

8. Report: output file path(s), key flags, and one concise refinement suggestion if useful.

Fast path: precise prompt + explicit “generate now” → quick reference/craft check, then CLI.

CLI resolution

Preferred call order:

# Existing CLI on PATH
gpt-image -p "PROMPT" [-f OUT] [-i REF...] [-m MASK] [options]

# Installed skill folder; use runtime-provided skill path when available
uv run "$SKILL_DIR/scripts/generate.py" -p "PROMPT" [-f OUT] [-i REF...] [-m MASK] [options]

# Direct transient CLI when the user requested setup/one-off CLI execution
uvx --from git+https://github.com/wuyoscar/gpt_image_2_skill gpt-image -p "PROMPT" [options]

scripts/generate.py is a launcher: repo-local src/gpt_image_cli → installed gpt-image → PATH gpt-image → transient uvx/uv fallback.

Key and cost rules

• CLI reads OPENAI_API_KEY from process env, then .env, then ~/.env without overriding existing env; successful API calls may bill the user’s OpenAI account.
• If host/runtime has native platform-managed image generation and the user wants that path, use the host tool instead of this CLI.
• If OPENAI_API_KEY is unset, report missing key or use host-native generation when requested; do not write secrets.
• If user wants to avoid local-key use, respect unset OPENAI_API_KEY; if a key exists in .env/~/.env, tell them to remove/rename it for the session rather than working around it.
• Never print secret values.

Flags

Flag	Values	Use
-p, --prompt	string	Required prompt/edit instruction
-f, --file	path	Output path; auto-named if omitted
-i, --image	repeatable path	Use edits endpoint; supports multiple references
-m, --mask	PNG path	Inpaint with alpha mask; requires -i
--model	default gpt-image-2	Image model
--size	1k, 2k, 4k, portrait, landscape, square, wide, tall, or literal	Canvas size
--quality	low, medium, high, auto	Cost/quality dial
-n, --n	integer	Number of images
--background	auto, opaque	Generation background
--moderation	auto, low	Generation moderation setting
--format	png, jpeg, webp	Output encoding
--compression	0-100	JPEG/WebP compression
--user	string	Optional end-user identifier

Quality policy:

• low: cheap drafts, broad exploration, many variants.
• medium: normal exploration, style probing, balanced cost.
• high: final assets, Chinese text, posters, diagrams, UI, paper figures, dense labels.

Size policy:

• default/social square: 1k / 1024x1024
• poster/mobile/beauty: portrait
• landscape/gameplay/photo: landscape
• print/paper figure: 2k
• widescreen hero: 4k
• vertical story/banner: tall

Endpoint routing

Mode	Trigger	Endpoint
Text-to-image	no -i	/v1/images/generations
Reference edit	one or more -i	/v1/images/edits
Inpaint	-i + -m	/v1/images/edits with mask

Surface API errors verbatim enough for debugging; exit codes: 0 success, 1 API/refusal, 2 bad args/missing key.

Reference loading

• references/gallery.md: routing index for the 162-prompt Reference Gallery Atlas. Load first.
• references/gallery-*.md: concrete prompts, previews, paths, metadata, attribution. Load 1 category for normal requests; 2–3 for hybrids.
• references/craft.md: prompt-craft checklist. Load for prompt repair, exact text, UI/data/diagram grammar, edit invariants, and multi-panel consistency.
• references/openai-cookbook.md: official parameter/model semantics. Load for API behavior or model capability questions.

Reference loading policy: load the smallest useful slice; never load all category files by default.

Verification

• Before API call: confirm endpoint mode, size, quality, output path, and required reference/mask files.
• After CLI call: report path(s) printed by the CLI and surface stderr on failure.
• For edits/inpaints: verify -i paths exist; verify -m exists when used.

Preserve Curated vs Author + Source metadata when adapting examples. Add new collected prompts to the Reference Gallery before README promotion.
