baronguyen001 Playwright PDF Snapshot
Use this skill when a script needs a browser-rendered artifact from a URL: a PDF report, a full-page PNG, or a dashboard capture. The helper runs Chromium headless through Playwright, accepts optional extra headers from the caller, and does not ship cookies or credentials.
When to invoke
- User says: "save this page as PDF", "capture a PNG snapshot", "archive the dashboard", "render this report URL".
- The page needs browser rendering rather than a raw HTTP download.
When NOT to invoke
- The URL is a static file that can be downloaded directly.
- The page requires a persisted login session; use [[playwright-login-session]] first and keep state files gitignored.
Concrete example
User input:
Render the public report URL to both a PDF and a PNG after the run finishes.
Output:
# Copy assets/snapshot.py into your project, then:
from snapshot import snapshot
paths = snapshot("https://example.com/report", out_dir="artifacts", name="report")
print(paths)
Install Playwright in the target project with pip install playwright and python -m playwright install chromium. Do not commit cookies, storage state, or private headers.
Pattern to apply
- Use headless Chromium and wait for network idle or a specific selector before capturing.
- Save both PDF and PNG only when the downstream workflow needs both.
- Keep auth out of this helper; pass public URLs or combine with a local, gitignored Playwright state file.
- Use stable filenames so artifact upload steps can find them.
- Pair with object storage when snapshots need to survive the local run.
