Playwright

Playwright CLI Skill

Drive a real browser from the terminal using playwright-cli. Prefer the bundled wrapper script so the CLI works even when it is not globally installed. Treat this skill as CLI-first automation. Do not pivot to @playwright/test unless the user explicitly asks for test files.

Choose this skill when:

• you want a short, reproducible terminal workflow or command sequence
• the target is a web app or website rather than Electron
• restarting or reopening the browser during debugging is acceptable
• you want snapshots, traces, or screenshots without maintaining a long-lived session

Use playwright-interactive instead when the same browser state must survive multiple edits, when the task is heavily iterative, or when you are debugging Electron.

Prerequisite check (required)

Before proposing commands, check whether npx is available (the wrapper depends on it):

command -v npx >/dev/null 2>&1

If it is not available, pause and ask the user to install Node.js/npm (which provides npx). Provide these steps verbatim:

# Verify Node/npm are installed
node --version
npm --version

# If missing, install Node.js/npm, then:
npm install -g @playwright/cli@latest
playwright-cli --help

Once npx is present, proceed with the wrapper script. A global install of playwright-cli is optional.

Skill path (set once)

export PWCLI="<path-to-skill>/scripts/playwright_cli.sh"

Resolve <path-to-skill> from the installed skill directory for your current agent. Do not hardcode ~/.codex or ~/.claude into reusable workflows.

Quick start

Use the wrapper script:

"$PWCLI" open https://playwright.dev --headed
"$PWCLI" snapshot
"$PWCLI" click e15
"$PWCLI" type "Playwright"
"$PWCLI" press Enter
"$PWCLI" screenshot

If the user prefers a global install, this is also valid:

npm install -g @playwright/cli@latest
playwright-cli --help

Core workflow

1. Open the page.
2. Snapshot to get stable element refs.
3. Interact using refs from the latest snapshot.
4. Re-snapshot after navigation or significant DOM changes.
5. Capture artifacts (screenshot, pdf, traces) when useful.

Minimal loop:

"$PWCLI" open https://example.com
"$PWCLI" snapshot
"$PWCLI" click e3
"$PWCLI" snapshot

When to snapshot again

Snapshot again after:

• navigation
• clicking elements that change the UI substantially
• opening/closing modals or menus
• tab switches

Refs can go stale. When a command fails due to a missing ref, snapshot again.

Recommended patterns

Form fill and submit

"$PWCLI" open https://example.com/form
"$PWCLI" snapshot
"$PWCLI" fill e1 "user@example.com"
"$PWCLI" fill e2 "password123"
"$PWCLI" click e3
"$PWCLI" snapshot

Debug a UI flow with traces

"$PWCLI" open https://example.com --headed
"$PWCLI" tracing-start
# ...interactions...
"$PWCLI" tracing-stop

Multi-tab work

"$PWCLI" tab-new https://example.com
"$PWCLI" tab-list
"$PWCLI" tab-select 0
"$PWCLI" snapshot

Wrapper script

The wrapper script uses npx --package @playwright/cli playwright-cli so the CLI can run without a global install:

"$PWCLI" --help

Prefer the wrapper unless the repository already standardizes on a global install.

References

Open only what you need:

• CLI command reference: references/cli.md
• Practical workflows and troubleshooting: references/workflows.md

TaleDraw Console Login

• For authenticated TaleDraw or TaleLens console checks, first run source "$HOME/.config/taledraw-test.env" in the active shell when available.
• Then prefer TALEDRAW_TEST_EMAIL and TALEDRAW_TEST_PASSWORD; if they are unset, fall back to TALELENS_TEST_EMAIL and TALELENS_TEST_PASSWORD.
• The final fallback source is macOS Keychain items codex-talelens-test-email and codex-talelens-test-password. Do not hardcode the credentials into repo files or ad hoc scripts.
• If either variable is missing, retrieve it with security find-generic-password -a talelens-test -s <service> -w for the active run, or ask the user to restore the Keychain items before continuing.

Guardrails

• Always snapshot before referencing element ids like e12.
• Re-snapshot when refs seem stale.
• Prefer explicit commands over eval and run-code unless needed.
• When you do not have a fresh snapshot, use placeholder refs like eX and say why; do not bypass refs with run-code.
• Use --headed when a visual check will help.
• When capturing artifacts in this repo, use output/playwright/ and avoid introducing new top-level artifact folders.
• Default to CLI commands and workflows, not Playwright test specs.
