Install
Claude.ai (Easiest — No Install)
Add the MCP connector and install the skill for the best experience:
- Go to Customize → Connectors → "Add custom connector"
- Paste:
https://demo.cbrowser.ai/mcp - Download the CBrowser Skill (.skill)
- Go to Customize → Skills → Upload the zip
- Start a new conversation and test your site
Note: The Claude.ai skill is a lightweight knowledge file that gives Claude context about CBrowser tools, pricing, and workflows. It works alongside the MCP connector. This is different from the Claude Code skill below, which is a full CLI integration.
Claude Code Skill (CLI)
For Claude Code terminal users — not for Claude.ai web:
curl -fsSL https://raw.githubusercontent.com/alexandriashai/cbrowser/main/scripts/install-skill.sh | bash
npm install -g cbrowser && npx playwright install
Then add to ~/.claude/skills/skill-index.json:
{"CBrowser": "~/.claude/skills/CBrowser/SKILL.md"}
See Claude-Skill-Installation for full guide.

What ONLY CBrowser Does
No other browser automation tool has these capabilities:
| Capability | What It Does | Why It Matters |
|---|---|---|
| Cognitive User Simulation | AI simulates how users think: patience, frustration, confusion | Test if real humans can use your site, not just if buttons click |
| Abandonment Detection | Automatically detects when users would give up | Find UX friction before losing customers |
| Site Knowledge Learning | Builds a knowledge graph per site: navigation maps, element reliability, goal paths | Each visit is better than the last. Gets smarter over time. |
| Page Understanding | Real-time page model: page type, interactive elements, forms, navigation | AI knows what each element does before clicking it |
| Constitutional Safety | Risk zones (Green/Yellow/Red/Black) prevent harmful actions | Safe to run AI agents unsupervised |
| Chaos Engineering | Inject failures: slow networks, timeouts, failed assets | Test error handling before real incidents |
| Autonomous Bug Hunting | AI explores your site and reports issues on its own | Finds bugs you didn't know to look for |
| **[[26 Cognitive Traits | Trait-Index]]** | patience, riskTolerance, selfEfficacy, siteFamiliarity, trustCalibration + 21 more |
| 21 Research-Backed Personas | 6 cognitive + 11 accessibility + 4 emotional personas | Each cites peer-reviewed HCI research with spectrum notes |
| siteFamiliarity Gating | Persona site knowledge scales to actual data available | Power-users on unknown sites are auto-downgraded to first-timers |
