Documentation

README

CDP — browser-harness-js skill

Custom codegen'd CDP SDK (every method from browser_protocol.json + js_protocol.json gets a typed wrapper) plus a tiny HTTP server that holds one persistent CDP Session. The browser-harness-js CLI auto-starts the server on first use and forwards JS snippets to it.

The SDK lives in the skill's sdk/ directory. In the rest of this doc, <skill-dir> refers to wherever npx skills add installed the skill (Claude Code: ~/.claude/skills/cdp; Cursor: ~/.cursor/skills/cdp; other agents vary). The CLI should be on PATH as browser-harness-js.

Setup (once, first use)
