Ray is an Agent Skill for documents published in the Railly/tinte repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Generate code screenshots via ray.tinte.dev API. Use when user asks for code screenshots, code images, code snippets as images, or says "ray". Calls POST https://ray.tinte.dev/api/v1/screenshot and saves the PNG result.

QUICK START

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

Open your project in Codex.
Copy and paste the prompt below.
Review files and risks before approving any action.

Prompt to paste

Inspect the Agent Skill at https://github.com/Railly/tinte/blob/HEAD/skills/ray/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/ray, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

Ray - Code Screenshots

Generate code screenshots by calling the ray.tinte.dev API.

API

POST https://ray.tinte.dev/api/v1/screenshot
Content-Type: application/json

Parameters

Param	Type	Default	Notes
`code`	string	required	1-10,000 chars
`language`	string	`"typescript"`	typescript, javascript, python, rust, go, java, cpp, c, html, css, json, bash, sql, markdown, toml
`theme`	string or TinteBlock	`"one-hunter"`	Slug from tinte.dev or inline object
`mode`	`"dark"` \| `"light"`	`"dark"`
`padding`	number	`32`	0-256
`fontSize`	number	`14`	8-32
`lineNumbers`	boolean	`true`
`title`	string	`""`	Window chrome title (max 100)
`background`	string	`"midnight"`	One of: midnight, sunset, ocean, forest, ember, steel, aurora, none. Hex colors are not accepted.
`format`	`"png"`	`"png"`	PNG only
`scale`	number	`2`	1-4 (retina)

Notes

background: "none" returns a transparent RGBA PNG. Useful when you want to composite the screenshot onto a custom background.
Returned PNGs always include some transparent margin around the window for the drop shadow, even with padding: 0. If you're compositing the result, trim that halo first (e.g. magick input.png -trim +repage output.png).
Long snippets can take 30-60+ seconds to render. Use a per-request timeout when calling from scripts or agents.

Workflow

Identify the code to screenshot (from file, clipboard, or user input)
Detect language from file extension or content
Call the API via curl
Save the PNG and open it

Example

curl -s -X POST https://ray.tinte.dev/api/v1/screenshot \
  -H 'Content-Type: application/json' \
  -d '{
    "code": "const greeting = \"Hello, world!\";",
    "language": "typescript",
    "theme": "one-hunter",
    "title": "hello.ts"
  }' -o screenshot.png && open screenshot.png

Language Detection

.ts, .tsx	typescript
.js, .jsx	javascript
