llm-image-generation SKILL.md skillB
llm-image-generation from black-yt/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add black-yt/skills/llm-image-generation@git:20260529.d765bbcPins git:20260529.d765bbc in mdr.lock. Pin the fingerprint instead.

当需要通过 OpenAI-compatible LLM 网关生成图片时使用，尤其是使用 LLM_API_KEY 和 LLM_BASE_URL 调用 gpt-image-2、gpt-image-1、dall-e-3 等图像模型；覆盖环境变量检查、缺失配置提示、模型选择、/images/generations 请求、长等待时间处理、base64/URL 返回保存和排错。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# LLM Image Generation
## 使用原则
- 优先从环境变量读取 `LLM_API_KEY` 和 `LLM_BASE_URL`，不要把 key 写进代码、日志、README 或命令输出。
- 如果环境变量缺失，先要求用户配置环境变量，不要猜测 key 或 base URL。
- 图像生成比普通 chat completion 慢很多。请求发出后 60-180 秒没有输出是常见情况；默认等待至少 180 秒，推荐超时设置为 300 秒。不要因为 30-60 秒无输出就判断失败。
- 输出图片保存到用户指定路径或当前项目的明确输出目录。仅测试时可以临时写入 `/tmp`，但验证后必须删除。
- 只在用户明确要求真实生成图片时调用接口；普通写作、提示词设计或代码生成不需要真的发图像请求。
## 环境变量
必需：
```bash
export LLM_API_KEY="sk-..."
export LLM_BASE_URL="http://host:port/v1"
```
可选：
```bash
export LLM_IMAGE_MODEL="gpt-image-2"
```
检查当前环境：
```bash
python3 - <<'PY'
import os
print("LLM_API_KEY:", "<set>" if os.environ.get("LLM_API_KEY") else "<unset>")
print("LLM_BASE_URL:", os.environ.get("LLM_BASE_URL", "<unset>"))
print("LLM_IMAGE_MODEL:", os.environ.get("LLM_IMAGE_MODEL", "<unset>"))
PY
```
如果 `LLM_API_KEY` 或 `LLM_BASE_URL` 是 `<unset>`，回复用户：
```text
当前环境缺少 LLM_API_KEY 或 LLM_BASE_URL。请先在 shell 中配置：
export LLM_API_KEY="sk-..."
export LLM_BASE_URL="http://host:port/v1"
如果有指定图像模型，也可以配置：
export LLM_IMAGE_MODEL="gpt-image-2"
```
## 模型选择
先查询模型列表，再选择模型：
```bash
python3 - <<'PY'
import os, json, urllib.request
base = os.environ["LLM_BASE_URL"].rstrip("/")
key = os.environ["LLM_API_KEY"]

How to install
mdr add black-yt/skills/llm-image-generation@sha256:b255ed05607a1690The line at the top of this page pins the label git:20260529.d765bbc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
