Workflow
工作流程
Step 1: Verify agent-browser Availability
步骤1:验证agent-browser是否可用
Before proceeding, verify that is available:
agent-browserbash
which agent-browserIf is not found in the PATH, inform the user that this skill requires agent-browser and cannot proceed without it.
agent-browser在开始前,验证是否可用:
agent-browserbash
which agent-browser如果在PATH中未找到,请告知用户此技能需要agent-browser,没有它无法继续。
agent-browserStep 2: Fetch Available Options
步骤2:获取可用选项
Fetch the current themes and languages from ray.so's GitHub repository using curl:
bash
undefined使用curl从ray.so的GitHub仓库获取当前的主题和语言:
bash
undefinedFetch and parse available themes
获取并解析可用主题
curl -s "https://raw.githubusercontent.com/raycast/ray-so/main/app/(navigation)/(code)/store/themes.ts" | grep -oE 'id:\s*"[^"]+"' | sed 's/id:\s*"//;s/"//' | sort -u
curl -s "https://raw.githubusercontent.com/raycast/ray-so/main/app/(navigation)/(code)/store/themes.ts" | grep -oE 'id:\s*"[^"]+"' | sed 's/id:\s*"//;s/"//' | sort -u
Fetch and parse available languages
获取并解析可用语言
curl -s "https://raw.githubusercontent.com/raycast/ray-so/main/app/(navigation)/(code)/util/languages.ts" | grep -oE '^[[:space:]]"?[a-zA-Z0-9+#-]+"?\s:\s*{' | sed 's/[[:space:]]"//g;s/".//;s/:.*//' | sort -u
undefinedcurl -s "https://raw.githubusercontent.com/raycast/ray-so/main/app/(navigation)/(code)/util/languages.ts" | grep -oE '^[[:space:]]"?[a-zA-Z0-9+#-]+"?\s:\s*{' | sed 's/[[:space:]]"//g;s/".//;s/:.*//' | sort -u
undefinedStep 3: Ask User for ALL Parameters
步骤3:向用户询问所有参数
MUST use AskUserQuestion to ask for EVERY parameter, presenting ALL available options. Ask for parameters in this order:
必须使用AskUserQuestion询问每一个参数,并展示所有可用选项。按以下顺序询问参数:
3.1 Theme Selection
3.1 主题选择
Present ALL available themes. In the question, list every theme fetched from step 2. Example:
Question: "Which theme would you like?"
Description: "Available themes: [list ALL themes from curl output]"
Options (pick 4 popular ones for quick select):
- breeze (default, purple gradient)
- midnight (cyan-blue)
- vercel (minimalist dark)
- sunset (warm orange)
Note: User can select "Other" to type any theme from the full list展示所有可用主题。在问题中列出步骤2获取的所有主题。示例:
问题:"你想要使用哪个主题?"
说明:"可用主题:[列出curl输出的所有主题]"
快速选择选项(挑选4个热门主题):
- breeze(默认,紫色渐变)
- midnight(青蓝色)
- vercel(极简深色)
- sunset(暖橙色)
注意:用户可以选择“其他”来输入完整列表中的任意主题3.2 Language Selection
3.2 语言选择
Infer the language when possible. Skip this question if:
- The user explicitly specified a language
- The code comes from a file with a clear extension (e.g., → python,
.py→ javascript,.js→ typescript,.ts→ rust,.rs→ go, etc.).go - The syntax is unmistakably identifiable (e.g., /
def→ python,import/func→ go,package/fn→ rust)let mut
Only ask this question if the language cannot be confidently inferred:
Question: "Which language for syntax highlighting?"
Description: "Available languages: [list ALL languages from curl output]"
Options:
- auto (auto-detect)
- javascript
- python
- typescript
Note: User can select "Other" to type any language from the full list尽可能推断语言。 在以下情况跳过此问题:
- 用户明确指定了语言
- 代码来自带有明确扩展名的文件(例如→python,
.py→javascript,.js→typescript,.ts→rust,.rs→go等).go - 语法具有明确辨识度(例如/
def→python,import/func→go,package/fn→rust)let mut
仅当无法可靠推断语言时才询问此问题:
问题:"使用哪种语言进行语法高亮?"
说明:"可用语言:[列出curl输出的所有语言]"
选项:
- auto(自动检测)
- javascript
- python
- typescript
注意:用户可以选择“其他”来输入完整列表中的任意语言3.3 Dark/Light Mode
3.3 深色/浅色模式
Question: "Dark or light mode?"
Options:
- Dark mode (default)
- Light mode问题:"深色模式还是浅色模式?"
选项:
- 深色模式(默认)
- 浅色模式3.4 Background
3.4 背景
Question: "Show the gradient background?"
Options:
- Yes, show background (default)
- No, transparent/minimal background问题:"显示渐变背景吗?"
选项:
- 是,显示背景(默认)
- 否,透明/极简背景3.5 Padding
3.5 内边距
Question: "How much padding around the code?"
Options:
- 16 (compact)
- 32 (small)
- 64 (medium, default)
- 128 (large)问题:"代码周围的内边距设置为多少?"
选项:
- 16(紧凑)
- 32(小)
- 64(中等,默认)
- 128(大)3.6 Line Numbers
3.6 行号
Question: "Show line numbers?"
Options:
- No (default)
- Yes问题:"显示行号吗?"
选项:
- 不显示(默认)
- 显示3.7 Title
3.7 标题
Question: "Add a title above the code? (e.g., filename)"
Options:
- No title (default)
- Yes, add title
If yes, ask for the title text.Note: Do NOT ask about output path/filename. Save to the current working directory with a sensible filename (e.g., , or based on the title if provided like ). Only use a different path if the user explicitly specifies one in their original request.
rayso-snippet.pngfibonacci.png问题:"在代码上方添加标题吗?(例如文件名)"
选项:
- 不添加标题(默认)
- 是,添加标题
如果选择是,询问标题文本。注意:不要询问输出路径/文件名。将图片保存到当前工作目录,使用合理的文件名(例如,如果提供了标题则使用类似的名称)。仅当用户在原始请求中明确指定时才使用其他路径。
rayso-snippet.pngfibonacci.pngStep 4: Build the ray.so URL
步骤4:构建ray.so链接
CRITICAL: ALL parameters must be in the URL hash (after #), NOT in the query string.
Build the URL using shell commands:
bash
undefined重要:所有参数必须放在URL的哈希部分(#之后),而不是查询字符串中。
使用shell命令构建链接:
bash
undefined1. Base64 encode the code
1. 对代码进行Base64编码
CODE_BASE64=$(echo -n 'YOUR_CODE_HERE' | base64)
CODE_BASE64=$(echo -n 'YOUR_CODE_HERE' | base64)
2. URL encode the base64 string
2. 对Base64字符串进行URL编码
CODE_ENCODED=$(python3 -c "import urllib.parse; print(urllib.parse.quote('$CODE_BASE64'))")
CODE_ENCODED=$(python3 -c "import urllib.parse; print(urllib.parse.quote('$CODE_BASE64'))")
3. Build the URL with ALL parameters in the hash
3. 构建包含所有参数的哈希部分的链接
Do NOT include width parameter - let ray.so auto-size to fit content
不要包含width参数 - 让ray.so自动调整大小以适配内容
Add optional parameters if needed:
如果需要,添加可选参数:
If lineNumbers: add "&lineNumbers=true" before &code=
如果显示行号:在&code=之前添加"&lineNumbers=true"
If title: add "&title=URL_ENCODED_TITLE" before &code=
如果有标题:在&code=之前添加"&title=URL_ENCODED_TITLE"
**URL Hash Parameters:**
| Parameter | Values | Default |
|-----------|--------|---------|
| theme | Any theme from list | breeze |
| padding | 16, 32, 64, 128 | 64 |
| background | true, false | true |
| darkMode | true, false | true |
| language | Any language from list, or "auto" | auto |
| lineNumbers | true, false | false |
| title | URL-encoded string | (none) |
| width | Number (pixels) | auto |
| code | Base64-encoded, then URL-encoded | (required) |
**Note on width:** Do NOT include the `width` parameter unless you specifically need a fixed width. Without it, ray.so auto-sizes the frame to fit the code content, avoiding unnecessary empty space.
**Example URL construction:**
```bash
**URL哈希参数:**
| 参数 | 取值 | 默认值 |
|-----------|--------|---------|
| theme | 列表中的任意主题 | breeze |
| padding | 16, 32, 64, 128 | 64 |
| background | true, false | true |
| darkMode | true, false | true |
| language | 列表中的任意语言,或"auto" | auto |
| lineNumbers | true, false | false |
| title | URL编码的字符串 | (无) |
| width | 数字(像素) | auto |
| code | Base64编码后再进行URL编码 | (必填) |
**关于width的注意事项:** 除非你需要固定宽度,否则不要包含`width`参数。不添加此参数时,ray.so会自动调整框架大小以适配代码内容,避免不必要的空白。
**链接构建示例:**
```bashFor code: for i in range(23):\n print(i)
代码:for i in range(23):\n print(i)
Theme: midnight, Padding: 64, Dark mode: true, Background: true, Language: python, Title: test.py
主题:midnight,内边距:64,深色模式:开启,背景:开启,语言:python,标题:test.py
CODE='for i in range(23):
print(i)'
CODE_BASE64=$(echo -n "$CODE" | base64)
CODE_ENCODED=$(python3 -c "import urllib.parse; print(urllib.parse.quote('$CODE_BASE64'))")
TITLE_ENCODED=$(python3 -c "import urllib.parse; print(urllib.parse.quote('test.py'))")
URL="https://ray.so/#theme=midnight&padding=64&background=true&darkMode=true&language=python&title=${TITLE_ENCODED}&code=${CODE_ENCODED}"
echo "$URL"
undefinedCODE='for i in range(23):
print(i)'
CODE_BASE64=$(echo -n "$CODE" | base64)
CODE_ENCODED=$(python3 -c "import urllib.parse; print(urllib.parse.quote('$CODE_BASE64'))")
TITLE_ENCODED=$(python3 -c "import urllib.parse; print(urllib.parse.quote('test.py'))")
URL="https://ray.so/#theme=midnight&padding=64&background=true&darkMode=true&language=python&title=${TITLE_ENCODED}&code=${CODE_ENCODED}"
echo "$URL"
undefinedStep 5: Capture High-Quality Image with agent-browser
步骤5:使用agent-browser捕获高质量图片
MUST use agent-browser (verified in Step 1). This approach uses the library (same as ray.so's internal export) with high pixelRatio for crisp, sharp text rendering.
html-to-imageIMPORTANT: Always use a unique session name with to avoid stale session issues.
--sessionbash
undefined必须使用agent-browser(步骤1已验证)。此方法使用库(与ray.so内部导出使用的库相同),并设置高pixelRatio以获得清晰锐利的文本渲染效果。
html-to-image重要提示: 始终使用参数指定唯一的会话名称,以避免会话过期问题。
--sessionbash
undefinedGenerate unique session name
生成唯一会话名称
SESSION="rayso-$(date +%s)"
SESSION="rayso-$(date +%s)"
1. Set viewport
1. 设置视口
agent-browser --session $SESSION set viewport 1400 900
agent-browser --session $SESSION set viewport 1400 900
2. Open the URL
2. 打开链接
agent-browser --session $SESSION open "$URL"
agent-browser --session $SESSION open "$URL"
3. Wait for the page to fully render
3. 等待页面完全渲染
agent-browser --session $SESSION wait --load networkidle
agent-browser --session $SESSION wait 3000
agent-browser --session $SESSION wait --load networkidle
agent-browser --session $SESSION wait 3000
4. Load html-to-image library (same library ray.so uses internally)
加载html-to-image库(与ray.so内部使用的库相同)
agent-browser --session $SESSION eval 'new Promise((r,e)=>{const s=document.createElement("script");s.src="https://cdn.jsdelivr.net/npm/html-to-image@1.11.11/dist/html-to-image.js";s.onload=r;s.onerror=e;document.head.appendChild(s)})'
agent-browser --session $SESSION eval 'new Promise((r,e)=>{const s=document.createElement("script");s.src="https://cdn.jsdelivr.net/npm/html-to-image@1.11.11/dist/html-to-image.js";s.onload=r;s.onerror=e;document.head.appendChild(s)})'
5. Capture at 4x resolution using html-to-image (produces crisp text)
4. 使用html-to-image以4倍分辨率捕获(生成清晰文本)
agent-browser --session $SESSION eval 'htmlToImage.toPng(document.querySelector("#frame > div"),{pixelRatio:4,skipAutoScale:true})' > /tmp/rayso-dataurl-$SESSION.txt
agent-browser --session $SESSION eval 'htmlToImage.toPng(document.querySelector("#frame > div"),{pixelRatio:4,skipAutoScale:true})' > /tmp/rayso-dataurl-$SESSION.txt
6. Close the browser
5. 关闭浏览器
agent-browser --session $SESSION close
agent-browser --session $SESSION close
7. Convert data URL to PNG file
6. 将数据URL转换为PNG文件
DATAURL=$(cat /tmp/rayso-dataurl-$SESSION.txt | tr -d '"' | tr -d '\n')
echo "$DATAURL" | sed 's/data:image/png;base64,//' | base64 -d > /path/to/output.png
DATAURL=$(cat /tmp/rayso-dataurl-$SESSION.txt | tr -d '"' | tr -d '\n')
echo "$DATAURL" | sed 's/data:image/png;base64,//' | base64 -d > /path/to/output.png
8. Clean up temp file
7. 清理临时文件
rm /tmp/rayso-dataurl-$SESSION.txt
**Critical notes:**
- Uses `html-to-image` library which is what ray.so uses for its own export feature
- `pixelRatio: 4` produces high-DPI images with crisp, sharp text (4x native resolution)
- The data URL is captured directly from the library, not from a screenshot
- No ImageMagick required - pure browser-based rendering at high resolution
- Output is correctly sized with no extra whitespacerm /tmp/rayso-dataurl-$SESSION.txt
**重要注意事项:**
- 使用`html-to-image`库,这是ray.so自身导出功能使用的库
- `pixelRatio: 4`生成高DPI图片,文本清晰锐利(4倍原生分辨率)
- 直接从库中捕获数据URL,而不是从截图中获取
- 不需要ImageMagick - 纯基于浏览器的高分辨率渲染
- 输出尺寸正确,无额外空白Step 6: Confirm Output and STOP
步骤6:确认输出并结束
Report the saved file location to the user. The task is complete - do not perform any additional checks, explorations, or verifications after the screenshot is saved.
向用户报告保存的文件位置。任务完成 - 截图保存后不要执行任何额外的检查、探索或验证操作。

图片分辨率与质量
This skill uses the library with to produce high-quality images with crisp, sharp text. This is the same rendering approach that ray.so uses for its built-in export feature.
html-to-imagepixelRatio: 4Output quality:
- Default: 4x native resolution (frame auto-sizes to content, then rendered at 4x)
- Text is rendered at high DPI, not upscaled from low resolution
- Gradient backgrounds and all CSS styling are preserved
- No unnecessary empty space (frame auto-sizes to fit code)
Adjusting resolution:
- For smaller files: Change to
pixelRatio:4in the eval commandpixelRatio:2 - For maximum quality: Use (same as ray.so's "6x" export option)
pixelRatio:6
Forcing a specific width:
- Only add to the URL if you need a fixed width (e.g., for consistent sizing across multiple images)
&width=NUMBER
此技能使用库并设置来生成高质量、文本清晰锐利的图片。这与ray.so内置导出功能使用的渲染方式相同。
html-to-imagepixelRatio: 4输出质量:
- 默认:4倍原生分辨率(框架自动调整大小以适配内容,然后以4倍分辨率渲染)
- 文本以高DPI渲染,而非从低分辨率放大
- 渐变背景和所有CSS样式均被保留
- 无不必要的空白(框架自动调整大小以适配代码)
调整分辨率:
- 如需更小的文件:在eval命令中将改为
pixelRatio:4pixelRatio:2 - 如需最高质量:使用(与ray.so的“6x”导出选项相同)
pixelRatio:6
强制固定宽度:
- 仅当需要固定宽度时才在URL中添加(例如,为了保持多张图片尺寸一致)
&width=NUMBER
Troubleshooting
故障排除
- If agent-browser is not available: Inform the user and do not proceed
- If curl fails to fetch themes/languages, use these common defaults:
- Themes: breeze, midnight, candy, crimson, falcon, meadow, raindrop, sunset, vercel, supabase, tailwind
- Languages: auto, javascript, typescript, python, rust, go, java, ruby, swift, kotlin, css, html, json, yaml, bash
- If parameters aren't applied: Ensure ALL parameters are in the URL hash (after #), not the query string
- If title isn't showing: The title parameter must be in the hash:
#title=filename.py&code=... - If html-to-image fails to load: Check network connectivity; the library loads from jsdelivr CDN
- If capture returns empty: The frame selector may have changed; inspect the page structure
#frame > div - For very long code snippets, ray.so may truncate; consider splitting into multiple images
- If the page doesn't load properly, increase the wait time (try 4000ms or more)
- If you get a blank page: Use a fresh unique session name with flag
--session - If data URL is malformed: Ensure quotes and newlines are stripped before base64 decoding
- 如果agent-browser不可用: 告知用户此技能需要agent-browser,无法继续
- 如果curl获取主题/语言失败,使用以下常用默认值:
- 主题:breeze, midnight, candy, crimson, falcon, meadow, raindrop, sunset, vercel, supabase, tailwind
- 语言:auto, javascript, typescript, python, rust, go, java, ruby, swift, kotlin, css, html, json, yaml, bash
- 如果参数未生效: 确保所有参数都在URL的哈希部分(#之后),而非查询字符串中
- 如果标题未显示: 标题参数必须在哈希部分:
#title=filename.py&code=... - 如果html-to-image加载失败: 检查网络连接;该库从jsdelivr CDN加载
- 如果捕获返回空内容: 框架选择器可能已更改;检查页面结构
#frame > div - 对于非常长的代码片段,ray.so可能会截断;考虑拆分为多张图片
- 如果页面加载不正常,增加等待时间(尝试4000ms或更长)
- 如果出现空白页面: 使用标志指定新的唯一会话名称
--session - 如果数据URL格式错误: 确保在Base64解码前去除引号和换行符
