Substack News

Collect and summarize Substack search results via browser automation.

Workflow

1. Open Substack Search

Run the browser automation script:

python "${SKILL_DIR}/scripts/scrape_substack.py" "SEARCH QUERY" [--range day|week|month]

For environments without Python, fall back to the manual agent-browser commands documented in references/browser-flow.md.

2. Output Format

Return results as a numbered list:

N. **Title**
   — Author · Publication · X min read — *one-line summary if available*

If fewer than 20 results exist on the page, report exactly what is found. No padding.

3. Scroll for More

The script auto-scrolls up to 3 times to capture additional results.

Substack typically returns 10-20 posts per 24-hour window.

Notes

• Substack search is behind JS rendering; web_fetch cannot extract it — browser automation is required.
• Time range filter: day (default), week, month.
• Close the browser session after extraction: agent-browser close.
