Skills

ScreenshotOne publishes reusable agent skills on GitHub:

https://github.com/screenshotone/skills

The repository is meant for agent workflows where you want to give an agent a focused ScreenshotOne capability instead of rebuilding screenshot logic from scratch for every task.

Included skills

Section titled “Included skills”

At the moment, the repository includes:

  • screenshotone-website-screenshot: take website screenshots with ScreenshotOne via curl

Install in Codex

Section titled “Install in Codex”

Codex discovers skills from:

  • $CODEX_HOME/skills
  • ~/.codex/skills when CODEX_HOME is not set

You can install the whole repository with:

Terminal window
npx skills add screenshotone/skills

Or copy only the ScreenshotOne screenshot skill:

Terminal window
mkdir -p ~/.codex/skills
cp -R screenshotone-website-screenshot ~/.codex/skills/

After installation, start a new Codex session or reload the app so it re-indexes the available skills.

Use the skill

Section titled “Use the skill”

Mention the skill by name in your prompt:

Use $screenshotone-website-screenshot to capture a full-page screenshot of https://example.com

Codex can also invoke the skill automatically when your request matches the skill description.

Repository structure

Section titled “Repository structure”

Each skill lives in its own folder and usually includes:

  • SKILL.md for the skill definition and instructions
  • agents/openai.yaml for UI metadata
  • references/ for optional supporting material

When to use skills

Section titled “When to use skills”

Skills are useful when you want to:

  • give an agent a reliable ScreenshotOne workflow
  • keep screenshot instructions reusable across projects
  • avoid repeating the same setup in every prompt

If you need more flexibility than a single skill, you can also use the CLI or MCP integrations.
