Playwright Automation Skill

Python-based browser automation for complex workflows requiring video recording, multi-page navigation, or data extraction.

When to Use

• Video recording of browser interactions
• Multi-page navigation sequences
• Data extraction with post-processing
• Form filling with validation
• Screenshot sequences or comparisons
• Any automation requiring Python logic

Wait Strategy Guide

Strategy	Use Case	Speed	Reliability
domcontentloaded	General web pages (default)	Fast (1-3s)	High
load	Media-heavy sites, SPAs	Medium (2-5s)	High
networkidle	Static sites that fully settle	Slow (5-30s+)	Variable

Recommendation: Use domcontentloaded (default) for most sites. Only use networkidle for static pages where you need all resources loaded.

Utility Scripts

Screenshot Utility

cd /workspace/.claude/skills/playwright-automation && \
uv run python scripts/screenshot.py <url> \
  [--full-page] \
  [--wait-until domcontentloaded|load|networkidle] \
  [--timeout 30000] \
  [--output filename.png]

Video Recorder

cd /workspace/.claude/skills/playwright-automation && \
uv run python scripts/video_recorder.py <url> \
  [--duration 10] \
  [--wait-until domcontentloaded|load|networkidle] \
  [--timeout 30000] \
  [--output filename.webm]

Common Patterns

Screenshot Capture

SCREENCAP_DIR = "/workspace/.claude/.data/playwright/screencaps"

# Full page
page.screenshot(path=f"{SCREENCAP_DIR}/full.png", full_page=True)

# Viewport only
page.screenshot(path=f"{SCREENCAP_DIR}/viewport.png")

# Specific element
page.locator("#element").screenshot(path=f"{SCREENCAP_DIR}/element.png")

# With options
page.screenshot(
    path=f"{SCREENCAP_DIR}/custom.jpg",
    type="jpeg",
    quality=80,
    clip={"x": 0, "y": 0, "width": 800, "height": 600}
)

Video Recording

VIDEO_DIR = "/workspace/.claude/.data/playwright/videos"

# Enable in context creation
context = browser.new_context(
    record_video_dir=VIDEO_DIR,
    record_video_size={"width": 1280, "height": 720}
)
page = context.new_page()
# ... perform actions ...

# CRITICAL: Get path BEFORE closing
video = page.video
video_path = video.path() if video else None
page.close()  # Video finalized here

Form Interaction

page.fill("#username", "testuser")
page.fill("#password", "testpass")
page.click("button[type='submit']")
page.select_option("#country", "US")
page.check("#agree-terms")
page.set_input_files("#file-upload", "/path/to/file.pdf")

Data Extraction

import json

DATA_DIR = "/workspace/.claude/.data/playwright/data"

title = page.locator("h1").text_content()
items = page.locator(".item").all()
data = [item.text_content() for item in items]

with open(f"{DATA_DIR}/extracted.json", "w") as f:
    json.dump({"title": title, "items": data}, f, indent=2)

Wait Strategies

# Wait for specific element
page.wait_for_selector("#dynamic-content")

# Wait for URL change
page.wait_for_url("**/success")

# Wait for load state (use sparingly)
page.wait_for_load_state("networkidle")

# Custom timeout
page.wait_for_selector("#slow-element", timeout=60000)

# Fixed delay for dynamic content
page.wait_for_timeout(2000)

Error Handling with Fallback

from playwright.sync_api import TimeoutError as PlaywrightTimeoutError

try:
    page.goto(url, wait_until="networkidle", timeout=30000)
except PlaywrightTimeoutError:
    # Fallback to faster strategy
    page.goto(url, wait_until="domcontentloaded", timeout=30000)

Tracing for Debug

DATA_DIR = "/workspace/.claude/.data/playwright/data"

context.tracing.start(screenshots=True, snapshots=True, sources=True)
# ... perform actions ...
context.tracing.stop(path=f"{DATA_DIR}/trace.zip")
# View with: playwright show-trace trace.zip

Execution

Run scripts using uv from the skill directory:

cd /workspace/.claude/skills/playwright-automation && uv run python scripts/<script>.py

Or for custom scripts in other locations:

cd /workspace/.claude/skills/playwright-automation && uv run python /path/to/custom_script.py

Troubleshooting

Issue	Solution
Browser launch fails	Ensure headless=True in container
Element not found	Use wait_for_selector() before interaction
Video not saved	Get page.video.path() BEFORE page.close()
Permission denied	Check output directory permissions
Timeout errors	Use domcontentloaded instead of networkidle
Streaming sites timeout	Add page.wait_for_timeout(3000) after navigation
