Summarise URL
When to use
The user has shared a URL and wants a quick understanding without reading the whole thing.
Steps
-
Fetch — use browser_markdown to get the page as clean text.
-
Extract structure — produce a summary with:
- Title (1 line)
- Source (publisher, author if available, date)
- Summary (2-3 sentences capturing the main point)
- Key points (3-5 bullet points covering the substantive claims or arguments)
- Takeaway (1 sentence: what should the reader do or think differently?)
-
Length-aware — if the page is very long (>3000 words):
- Keep summary to 100 words max
- Limit key points to 5 maximum
- Skip filler sections (related links, ads, comments)
-
Use UI elements where helpful:
show_alert for important caveats (paywall, opinion piece, sponsored content)
offer_choices at the end: "Read in full", "Find related articles", "Save to memory"
Style
- Be objective. If the article is opinionated, note that — don't echo its tone.
- Avoid hedging language ("seems to suggest"). Be direct.
- Preserve specific numbers and quotes that matter; paraphrase the rest.
What not to do
- Don't pretend you read more than was returned. If
browser_markdown returns partial content, say so.
- Don't ignore the date — old articles may be outdated.
- Don't include section headers from the page verbatim — synthesise.
