Writing CDP Scripts

txtar header comments, helper .js, and helper .cdp files are optional

Use this skill for

choosing between inline commands and sourced helpers
wiring environment variables and output artifacts
explaining assertions, waits, snapshots, and extraction commands

Operates the cdp CLI for browser navigation, element interaction, JavaScript evaluation, browser attachment, and interactive REPL workflows. Use when the task involves driving Chrome or Chromium with the repo's cdp command, exploring available commands, or choosing between interactive and scripted execution.
