Prefer the bundled wrapper script so the CLI works even when it is not globally installed.\nTreat this skill as CLI-first automation. Do not pivot to `@playwright\u002Ftest` unless the user explicitly asks for test files.\n\n## Prerequisite check (required)\n\nBefore proposing commands, check whether `npx` is available (the wrapper depends on it):\n\n```bash\ncommand -v npx >\u002Fdev\u002Fnull 2>&1\n```\n\nIf it is not available, pause and ask the user to install Node.js\u002Fnpm (which provides `npx`). Provide these steps verbatim:\n\n```bash\n# Verify Node\u002Fnpm are installed\nnode --version\nnpm --version\n\n# If missing, install Node.js\u002Fnpm, then:\nnpm install -g @playwright\u002Fcli@latest\nplaywright-cli --help\n```\n\nOnce `npx` is present, proceed with the wrapper script. A global install of `playwright-cli` is optional.\n\n## Skill path (set once)\n\n```bash\nexport CODEX_HOME=\"${CODEX_HOME:-$HOME\u002F.codex}\"\nexport PWCLI=\"$CODEX_HOME\u002Fskills\u002Fplaywright\u002Fscripts\u002Fplaywright_cli.sh\"\n```\n\nUser-scoped skills install under `$CODEX_HOME\u002Fskills` (default: `~\u002F.codex\u002Fskills`).\n\n## Quick start\n\nUse the wrapper script:\n\n```bash\n\"$PWCLI\" open https:\u002F\u002Fplaywright.dev --headed\n\"$PWCLI\" snapshot\n\"$PWCLI\" click e15\n\"$PWCLI\" type \"Playwright\"\n\"$PWCLI\" press Enter\n\"$PWCLI\" screenshot\n```\n\nIf the user prefers a global install, this is also valid:\n\n```bash\nnpm install -g @playwright\u002Fcli@latest\nplaywright-cli --help\n```\n\n## Core workflow\n\n1. Open the page.\n2. Snapshot to get stable element refs.\n3. Interact using refs from the latest snapshot.\n4. Re-snapshot after navigation or significant DOM changes.\n5. Capture artifacts (screenshot, pdf, traces) when useful.\n\nMinimal loop:\n\n```bash\n\"$PWCLI\" open https:\u002F\u002Fexample.com\n\"$PWCLI\" snapshot\n\"$PWCLI\" click e3\n\"$PWCLI\" snapshot\n```\n\n## When to snapshot again\n\nSnapshot again after:\n\n- navigation\n- clicking elements that change the UI substantially\n- opening\u002Fclosing modals or menus\n- tab switches\n\nRefs can go stale. When a command fails due to a missing ref, snapshot again.\n\n## Recommended patterns\n\n### Form fill and submit\n\n```bash\n\"$PWCLI\" open https:\u002F\u002Fexample.com\u002Fform\n\"$PWCLI\" snapshot\n\"$PWCLI\" fill e1 \"user@example.com\"\n\"$PWCLI\" fill e2 \"password123\"\n\"$PWCLI\" click e3\n\"$PWCLI\" snapshot\n```\n\n### Debug a UI flow with traces\n\n```bash\n\"$PWCLI\" open https:\u002F\u002Fexample.com --headed\n\"$PWCLI\" tracing-start\n# ...interactions...\n\"$PWCLI\" tracing-stop\n```\n\n### Multi-tab work\n\n```bash\n\"$PWCLI\" tab-new https:\u002F\u002Fexample.com\n\"$PWCLI\" tab-list\n\"$PWCLI\" tab-select 0\n\"$PWCLI\" snapshot\n```\n\n## Wrapper script\n\nThe wrapper script uses `npx --package @playwright\u002Fcli playwright-cli` so the CLI can run without a global install:\n\n```bash\n\"$PWCLI\" --help\n```\n\nPrefer the wrapper unless the repository already standardizes on a global install.\n\n## References\n\nOpen only what you need:\n\n- CLI command reference: `references\u002Fcli.md`\n- Practical workflows and troubleshooting: `references\u002Fworkflows.md`\n\n## Guardrails\n\n- Always snapshot before referencing element ids like `e12`.\n- Re-snapshot when refs seem stale.\n- Prefer explicit commands over `eval` and `run-code` unless needed.\n- When you do not have a fresh snapshot, use placeholder refs like `eX` and say why; do not bypass refs with `run-code`.\n- Use `--headed` when a visual check will help.\n- When capturing artifacts in this repo, use `output\u002Fplaywright\u002F` and avoid introducing new top-level artifact folders.\n- Default to CLI commands and workflows, not Playwright test specs.\n",{"data":36,"body":41},{"name":4,"description":6,"metadata":37},{"short-description":38,"author":39,"source":40},"Automate real browsers from the terminal","OpenAI","https:\u002F\u002Fgithub.com\u002Fopenai\u002Fskills\u002Ftree\u002Fmain\u002Fskills\u002F.curated\u002Fplaywright",{"type":42,"children":43},"root",[44,53,76,83,96,146,158,257,276,282,385,406,412,417,578,583,620,626,656,661,754,760,765,789,794,800,807,974,980,1063,1069,1165,1171,1184,1210,1215,1221,1226,1251,1257,1348],{"type":45,"tag":46,"props":47,"children":49},"element","h1",{"id":48},"playwright-cli-skill",[50],{"type":51,"value":52},"text","Playwright CLI Skill",{"type":45,"tag":54,"props":55,"children":56},"p",{},[57,59,66,68,74],{"type":51,"value":58},"Drive a real browser from the terminal using ",{"type":45,"tag":60,"props":61,"children":63},"code",{"className":62},[],[64],{"type":51,"value":65},"playwright-cli",{"type":51,"value":67},".
