Problem Statement

Problem

When using Claude Code in VS Code, users often need to analyze or describe images (screenshots, diagrams, UI mockups, etc.) during development. Currently, Claude Code lacks a built-in tool to read and interpret image files.

GitHub Copilot has a powerful built-in view_image tool that allows the assistant to read PNG/JPG/GIF/WebP images and describe their contents. This is extremely useful for:

• Analyzing UI/UX screenshots
• Reading diagrams and architecture drawings
• Debugging visual issues
• Understanding test output screenshots

Feature Request

Add a view_image (or similar) tool that Claude Code can invoke to read image files and provide their content/description to the language model.

Proposed Solution

Suggested Implementation

Following VS Code's Language Model Tools API (vscode.lm.registerTool), the tool could:

1. Accept a file path as input
2. Read the image file using vscode.workspace.fs.readFile()
3. Convert the image to a format compatible with the underlying model (e.g., base64)
4. Return the image data as a tool result

The tool declaration in package.json would use the languageModelTools contribution point.
