Cavepaintings Marketplace
Add a browser drawing canvas so you can diagram architecture, mark up screenshots, and hand visuals straight back to Claude Code.
Overview
cavepaintings-marketplace is a plugin marketplace for the Build phase that adds a browser drawing canvas for diagramming, annotating images, and submitting visuals to Claude Code.
What is this marketplace?
- Single-plugin marketplace (cavepaintings v0.3.4) for Claude Code
- Browser-based canvas for freehand drawing and structured diagrams
- Image annotation workflow for UI bugs, wireframes, and architecture sketches
- Submits finished visuals into the active Claude Code session
- No separate desktop app—works in the browser alongside your editor
- 1 plugin in marketplace (cavepaintings)
- Marketplace and plugin version 0.3.4
What problem does it solve?
Explaining UI, architecture, or bugs to your coding agent with text alone is slow and often ambiguous.
Who is it for?
Indie developers who live in Claude Code and want lightweight diagrams and screenshot markup without leaving the agent workflow.
Skip if: Teams that need Figma-grade design systems, collaborative multi-user whiteboards, or non-Claude agents.
What do I get? / Deliverables
You sketch or annotate in the browser and feed the visual directly into Claude Code so the agent works from the same picture you have in mind.
- Registered cavepaintings plugin in your Claude Code environment
- Diagrams and annotated images submitted into agent context

Recommended Marketplaces
Journey fit
Visual explanation and annotation happen while you are building and pairing with the agent, not after launch. The lone plugin extends Claude Code with in-session visuals—classic agent-tooling for clearer specs and debugging screenshots.
How it compares
Agent visual plugin, not a standalone design SaaS or MCP server catalog.
