catalan-adobe/cdp-connect
Connect Claude Code to an existing Chrome browser via CDP (Chrome DevTools Protocol). Zero dependencies — uses Node 22 built-in WebSocket. Attach to any Chrome running with --remote-debugging-port, then navigate, click, type, screenshot, evaluate JS, read accessibility tree, and monitor console/network. Use when you need to interact with a browser the agent already started, control an existing Chrome instance, or drive browser automation without Playwright MCP. Triggers on: cdp connect, connect to browser, connect to chrome, attach to browser, interact with browser, drive browser, browser automation, control chrome, connect 9222.

Quality
Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is an excellent skill description that hits all the marks. It provides specific concrete actions, comprehensive trigger terms covering both technical and natural language, explicit 'Use when' guidance with clear scenarios, and distinguishes itself from similar tools like Playwright MCP. The description is information-dense without being verbose.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'navigate, click, type, screenshot, evaluate JS, read accessibility tree, and monitor console/network'. Also specifies technical details like 'Node 22 built-in WebSocket' and '--remote-debugging-port'. | 3 / 3 |
Completeness | Clearly answers both what ('Connect Claude Code to an existing Chrome browser via CDP... navigate, click, type, screenshot...') AND when ('Use when you need to interact with a browser the agent already started, control an existing Chrome instance, or drive browser automation without Playwright MCP'). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'cdp connect, connect to browser, connect to chrome, attach to browser, interact with browser, drive browser, browser automation, control chrome, connect 9222'. Includes both technical (CDP, 9222) and natural language variations. | 3 / 3 |
Distinctiveness Conflict Risk | Clear niche with distinct triggers focused on CDP/Chrome DevTools Protocol and connecting to existing browsers. Explicitly differentiates from Playwright MCP ('without Playwright MCP'), reducing conflict risk with other browser automation skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is an excellent skill file that exemplifies best practices. It's concise yet complete, provides fully executable commands with clear syntax, includes a logical workflow with verification steps, and organizes content into easily scannable sections. The tips section adds valuable context without bloating the core instructions.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. No unnecessary explanations of what CDP is or how WebSockets work. Every section serves a purpose with minimal prose. | 3 / 3 |
Actionability | Fully executable commands with clear syntax, flags, and examples. The script section provides copy-paste ready code for locating the tool, and all commands show exact usage patterns. | 3 / 3 |
Workflow Clarity | Clear 5-step workflow (Discover → Understand → Interact → Verify → Debug) with explicit verification step using screenshots. The sequence is logical and includes validation through visual confirmation. | 3 / 3 |
Progressive Disclosure | Well-organized with clear sections (Prerequisites, Script, Commands, Workflow, Tips). Content is appropriately sized for a single SKILL.md without needing external references. Easy to scan and navigate. | 3 / 3 |
Total | 12 / 12 Passed |
