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.

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 covers all dimensions thoroughly. It provides specific concrete actions, comprehensive trigger terms, explicit 'Use when' guidance with differentiation from similar tools (Playwright MCP), and a clear technical niche (CDP protocol). The description is well-structured and uses proper third-person voice throughout.

DimensionReasoningScore

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 to Chrome via CDP, navigate, click, type, screenshot, etc.) and 'when' (explicit 'Use when...' clause with specific scenarios plus a 'Triggers on:' list of keywords).

3 / 3

Trigger Term Quality

Excellent coverage of natural trigger terms including 'cdp connect', 'connect to browser', 'connect to chrome', 'attach to browser', 'browser automation', 'control chrome', 'connect 9222'. These cover many natural phrasings a user might use.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive — specifically targets CDP/Chrome DevTools Protocol connection to an existing browser, and explicitly differentiates from Playwright MCP ('without Playwright MCP'). The port number 9222 and CDP-specific terminology create a clear niche.

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 is lean, actionable, and well-structured. It assumes Claude's competence, provides executable commands for every operation, and includes a clear workflow with verification steps. The tips section adds genuinely useful guidance including the security warning about external content.

DimensionReasoningScore

Conciseness

Every section earns its place. No explanation of what CDP is or how WebSockets work. The prerequisites, command reference, and workflow are all tightly written with no padding.

3 / 3

Actionability

Provides fully executable bash commands for every operation, a concrete script block for locating the cdp.js file, and specific examples including eval with promises. All commands are copy-paste ready with clear argument syntax.

3 / 3

Workflow Clarity

The 5-step workflow (Discover → Understand → Interact → Verify → Debug) is clearly sequenced with explicit verification via screenshot + Read tool. The workflow naturally includes validation checkpoints and the tips section covers error recovery scenarios like timeouts.

3 / 3

Progressive Disclosure

Content is well-structured with clear sections (Prerequisites, Script, Commands, Workflow, Tips) that progress from setup to usage. The skill references an external script file (cdp.js) appropriately, keeping the SKILL.md as an overview without inlining implementation details.
