Screenshot Capture

Capture high-quality screenshots of any public URL at custom resolutions. Supports desktop and mobile viewports, full-page captures, and specific element targeting. Ideal for visual monitoring, design research, and content archival. Read the API map before selecting a capability.

Call SandBase capabilities

For every selected tool, call sandbase_describe_tool first and use only arguments in its current input schema. Then call sandbase_call_tool with the exact tool_name.

Available Tools

  • strale_screenshot_url
  • context_dev_capture_screenshot

Workflow

  • Understand the user's research question, target, and context.
  • Call sandbase_describe_tool for each selected tool to confirm parameter schema.
  • Call sandbase_call_tool with the exact tool_name and schema-defined arguments.
  • Synthesize findings into a clear, evidence-backed answer.
  • Cite sources, note evidence gaps, and separate observations from interpretations.

Guidelines

  • Always call sandbase_describe_tool before using any capability.
  • Cite sources and preserve attribution (URLs, usernames, dates, metrics).
  • Separate factual observations from analysis and recommendations.
  • If data is unavailable, note the gap and continue with available evidence.
  • Read-only research only. Never take actions on platforms.

How to use it

Copy the folder

Take sandbaseai/screenshot-capture from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
