playwright-cliDrive a browser from the terminal with playwright-cli: snapshot the page, then act on elements by ref.
Playwright CLI is an agent skill from lexler/skill-factory. Drive a browser from the terminal with playwright-cli: snapshot the page, then act on elements by ref. Use when automating browser interactions, filling web forms, testing UIs, or driving logged-in web apps from the command line.
Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/attaching-to-chrome.md` and `references/full-command-reference.md`).
It sits in Testing & QA, covering Browser testing. It works with Playwright. The licence is Apache-2.0.
Read from SKILL.md and the folder at commit 8017333. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Playwright CLI loads about 835 tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 61 tokens; SKILL.md has 251 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Driving a browser from the shell. Each command prints the executed Playwright code, the page state, and a fresh snapshot.
Snapshot to see the page, act on an element by its ref, snapshot again.
playwright-cli snapshot # accessibility tree with [ref=e8] handles
playwright-cli click e8 # act on a ref
playwright-cli snapshot # confirm the resultRefs are not stable. Any DOM change renumbers them — re-snapshot before acting on a page that just changed. Acting on a stale ref hits the wrong element or none.
For a large page, snapshot a region instead of the whole tree: snapshot e34 or snapshot --depth=4.
A target is one of three things — a ref, a CSS selector, or a Playwright locator:
playwright-cli click e8
playwright-cli click ".todo-list .toggle"
playwright-cli click "getByRole('button', { name: 'Submit' })"
playwright-cli click "getByText('buy milk')"A bare descriptive phrase is not a target. click "the submit button" is parsed as a CSS selector and fails with "does not match any elements". Prefer refs; reach for getByRole/getByText when a ref won't survive a re-render.
playwright-cli goto https://example.com
playwright-cli fill e5 "user@example.com" --submit # clear, type, then Enter — one step
playwright-cli type "free text into the focused element"
playwright-cli press Enter # also: Tab, Escape, ArrowDown
playwright-cli select e9 "option-value"
playwright-cli check e12 # uncheck / hover / dblclick likewise
playwright-cli screenshot # saves to .playwright-cli/fill works on React/controlled inputs where raw DOM events don't. After filling, the field must blur before dependent values (totals, validation) update — --submit or a following press Tab does that.
playwright-cli eval "el => el.getAttribute('data-testid')" e5 # attributes the snapshot hides
playwright-cli console # page console messages
playwright-cli requests # network log, then `request <n>`--raw strips the wrapper so output pipes, and proves what an action changed:
playwright-cli --raw snapshot > before.yml
playwright-cli click e8
playwright-cli --raw snapshot > after.yml
diff before.yml after.ymlopen launches a fresh browser; --persistent keeps cookies across runs. To drive an already-running, logged-in browser instead, attach over CDP. See references/attaching-to-chrome.md.
Name parallel browsers with -s=<name> (omit it for the implicit default session). playwright-cli list, close, close-all.
The above is the working subset. The CLI ships its own exhaustive reference — tabs, storage, mocking, tracing, video, codegen. See references/full-command-reference.md.

Playwright CLI fits situations like: automating browser interactions; filling web forms; driving logged-in web apps from the command line.
Run `npx skills add lexler/skill-factory --skill playwright-cli -a claude-code`. Or copy the skill folder (output_skills/developer-tools/playwright-cli in lexler/skill-factory) into .claude/skills/playwright-cli in your project. Claude Code loads it when a task matches its description.
Run `npx skills add lexler/skill-factory --skill playwright-cli -a codex`. Or copy the skill folder (output_skills/developer-tools/playwright-cli in lexler/skill-factory) into .agents/skills/playwright-cli in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add lexler/skill-factory --skill playwright-cli -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/playwright-cli, .gemini/skills/playwright-cli, .github/skills/playwright-cli and .opencode/skills/playwright-cli in your project.
SKILL.md names no scripts, command-line tools or credentials: Playwright CLI is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Playwright CLI is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 835 tokens (SKILL.md is roughly 3.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 729 tokens, read only when the agent opens those files.
