screen-aware

screen-aware is a skill for Claude Code, Codex from GOWTHAM2036/SightMCP. It costs 66 tokens per session (870 once invoked), scanned A, original, MIT.

A workflow for connecting what a user points to on their screen with the matching part of a codebase. It uses the current screen, cursor position, and active window to identify visual targets and verify UI changes.

In plain words
What is it for?
Use it to locate the source of a visible interface element, modify it, and check the result against the screen.
Why use it?
It reduces guesswork when a user refers to something visible, such as “this button” or “that color.”

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

screen-aware scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Screen-Aware Development & Visual Targeting Skill

This skill teaches the agent how to leverage the Screen-Aware MCP tools to ground user intent in the current computer screen state, locate matching source components, apply modifications, and visually verify the results.


🧭 Core Principles & Rules of Engagement

  1. Obtain Fresh Context for Visual References:

    • Whenever the user refers to something visible on screen or uses deictic pointers ("this", "here", "that button", "the navbar icon"), call capture_screen_context() immediately.
    • Never hallucinate or guess what is on the screen without capturing fresh screen context.
  2. Combine Screenshot and Cursor Coordinates:

    • Use the mouse cursor coordinates (x, y) and normalized coordinates (normalized_x, normalized_y) in tandem with the visual screenshot.
    • Reason about the specific UI element directly located under or nearest to the cursor position.
  3. Grounding to Source Code:

    • After visually identifying the target element from the screenshot and active window:
      1. Note key semantic text, class names, icons, labels, or layout attributes visible in the element.
      2. Search the codebase for corresponding templates, components, JSX/TSX elements, or CSS rules.
      3. Ensure you have accurately located the component before modifying code.
  4. Visual Verification Loop:

    • After applying code modifications and allowing the UI / hot-reload to refresh:
      1. Call capture_screen_context() (or capture_screen()) to capture an updated screen frame.
      2. Visually verify that the requested visual changes (e.g., color, size, padding, alignment) have taken effect as requested.
      3. Report the verified outcome clearly to the user.
  5. Security & Privacy Guardrails:

    • Never log or display sensitive personal information, credentials, or private message content captured in screenshots.
    • Ask for user confirmation before executing any destructive operations.
