# Playwright > Use globally installed `playwright-cli` for browser automation, UI inspection, screenshots, Playwright test debugging, or test generation. Trigger when a task needs browser interaction or test repair. Do not use for generic tests, web search, non-browser docs, or API-only work. - Skill: `conn-castle/playwright` (Agent Skill, multi-file: 4 files) - Install (CLI): `npx skillmds@latest add conn-castle/playwright` - Raw SKILL.md: https://api.skillmd.com/api/skills/conn-castle/playwright/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: AI & ML - License: Apache-2.0 - Author: conn-castle (https://skillmd.com/u/conn-castle) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/conn-castle/playwright --- # Browser Automation with playwright-cli > Modified by Conn Castle Studios on 2026-05-26 from the Apache-2.0 > playwright-cli skill: reduced duplicated command reference material and > tailored the workflow guidance for Agent Layer. Use globally installed `playwright-cli` as the browser control surface. This skill provides routing, safety, and workflow rules; installed CLI help provides command syntax. ## Defaults - Use snapshots and element refs for navigation. - Use screenshots only when visual evidence matters. - Use references only for Playwright test debugging or test generation. - Create no durable artifact unless the task needs one. ## Required artifacts - No artifact is required for ordinary inspection. - Put agent-only scripts, state files, traces, videos, screenshots, and saved snapshots under `.agent-layer/tmp/`. - Report every artifact path created. ## Global constraints - Run `playwright-cli --version` before the first `playwright-cli` command in a session. Stop if it is missing. - Run `playwright-cli --help` before the first `playwright-cli` command in a session. - Run `playwright-cli --help ` before using a non-obvious subcommand or flag. - Treat installed CLI help as the source of truth for commands, arguments, flags, and defaults. - Keep short help-probe lists as routing hints, not command documentation. Always query live help before using a listed command. - If CLI, browser, app, or test setup is missing, stop and report the missing requirement; do not install packages or browsers unless the user asked for setup. - Do not run `playwright-cli install --skills`. - Do not hard-code or expose secrets in commands, tests, storage state, traces, videos, screenshots, or logs. ## Human checkpoints - Ask before installing CLI packages, installing browsers, changing browser configuration, or using a persistent profile outside an explicit user request. - Ask before saving or reusing authentication state outside `.agent-layer/tmp/`. - Ask before leaving a browser session running when the user did not request an interactive handoff. ## Workflow 1. Start or connect to the browser using the command shape from live help. 2. Capture semantic page state and use element refs for normal interaction. 3. Use screenshots only for visual verification. 4. Use selectors or Playwright locators only when refs are insufficient. 5. When refs omit needed details, choose the inspection or output mode from live subcommand help. 6. Use dashboard or visual-aid features from live help when the user needs to identify or comment on UI. 7. End, disconnect from, or report any remaining session before handoff. ## Help probes Use these as `playwright-cli --help ` targets, not as syntax documentation: - Browser/session lifecycle: `open`, `attach`, `list`, `close`, `detach`, `close-all`, `kill-all`. - Page state and inspection: `snapshot`, `screenshot`, `eval`, `console`, `requests`, `request`. - UI clarification: `show`, `highlight`. - Storage and auth state: `state-save`, `state-load`, cookie and storage commands from root help. - Network mocking and advanced browser logic: `route`, `run-code`. - Debugging evidence: `tracing-start`, `tracing-stop`, `video-start`, `video-stop`. ## Conditional references - Read [references/playwright-tests.md](references/playwright-tests.md) when running, debugging, or healing Playwright tests, especially with `npx playwright test --debug=cli` sessions. - Read [references/test-generation.md](references/test-generation.md) when creating or updating Playwright tests from interactive browser actions, generated Playwright code, or manually added assertions. ## Operational notes - Named sessions isolate cookies, storage, cache, history, and tabs; use semantic names and clean them up. - Saved storage state can contain credentials; keep it temporary and uncommitted. - For failed HTTP activity, use live help to find inspection commands; do not invent command groups. - Prefer built-in commands for simple mocks or browser operations; use code-execution from live help only when a simpler command cannot express the behavior. - Use replay or recording artifacts only when they provide needed evidence. Clean up large artifacts. ## Guardrails - Do not guess command names, flags, session behavior, or install commands. - Do not use Playwright automation to bypass authentication, authorization, or site terms. - Do not hard-code secrets, tokens, or real credentials into commands, test files, storage state, logs, screenshots, videos, or traces. - Do not add sleeps or skip Playwright hooks to make a test pass. Diagnose the app state and wait for specific, testable readiness instead. ## Definition of done - The installed CLI help was checked for each command shape used. - Browser sessions were closed, detached, or intentionally left running with that state reported. - Generated artifacts were saved only where appropriate and secrets were not committed or exposed. - For Playwright test work, the relevant reference file was followed and the smallest meaningful test was rerun. ## Final handoff State which pages, flows, or tests were exercised; name any files or artifacts created; summarize cleanup; and report any verification that could not be run.
