Serper
Google search via Serper API. Fetches results AND reads the actual web pages to extract clean full-text content via trafilatura. Not just snippets — full article text.
Constraint
This skill already fetches and extracts full page content. Do NOT use WebFetch, web_fetch, WebSearch, browser tools, or any other URL-fetching/browsing tool on the URLs returned by this skill. The content is already included in the output. Never follow up with a separate fetch — everything you need is in the results.
Query Discipline
Craft ONE good search query. That is almost always enough.
Each call returns multiple results with full page text — you get broad coverage from a single query. Do not run multiple searches to "explore" a topic. One well-chosen query with the right mode covers it.
At most two calls if the user's request genuinely spans two distinct topics (e.g. "compare X vs Y" where X and Y need separate searches, or one default + one current call for different aspects). Never more than two.
Do NOT:
- Run the same query with different wording to "get more results"
- Run sequential searches to "dig deeper" — the full page content is already deep
- Run one search to find something, then another to follow up — read the content you already have
Two Search Modes
There are exactly two modes. Pick the right one based on the query:
default — General search (all-time)
- All-time Google web search, 5 results, each enriched with full page content
- Use for: general questions, research, how-to, evergreen topics, product info, technical docs, comparisons, tutorials, anything NOT time-sensitive
current — News and recent info
- Past-week Google web search (3 results) + Google News (3 results), each enriched with full page content
- Use for: news, current events, recent developments, breaking news, announcements, anything time-sensitive
Mode Selection Guide
| Query signals |
Mode |
| "how does X work", "what is X", "explain X" |
default |
| Product research, comparisons, tutorials |
default |
| Technical documentation, guides |
default |
| Historical topics, evergreen content |
default |
| "news", "latest", "today", "this week", "recent" |
current |
| "what happened", "breaking", "announced", "released" |
current |
| Current events, politics, sports scores, stock prices |
current |
Locale
Default is global — no country filter, English results. This ONLY works for English queries.
You MUST ALWAYS set --gl and --hl when ANY of these are true:
- The user's message is in a non-English language
- The search query you construct is in a non-English language
- The user mentions a specific country, city, or region
- The user asks for local results (prices, news, stores, etc.) in a non-English context
If the user writes in German, you MUST pass --gl de --hl de. No exceptions.
| Scenario |
Flags |
| English query, no country target |
(omit --gl and --hl) |
| German query OR user writes in German OR targeting DE/AT/CH |
--gl de --hl de |
| French query OR user writes in French OR targeting France |
--gl fr --hl fr |
| Any other non-English language/country |
--gl XX --hl XX (ISO codes) |
Rule of thumb: If the query string contains non-English words, set --gl and --hl to match that language.
How to Invoke
python3 scripts/search.py -q "QUERY" [--mode MODE] [--gl COUNTRY] [--hl LANG]
Examples
# English, general research
python3 scripts/search.py -q "how does HTTPS work"
# English, time-sensitive
python3 scripts/search.py -q "OpenAI latest announcements" --mode current
# German query — set locale + current mode for news/prices
python3 scripts/search.py -q "aktuelle Preise iPhone" --mode current --gl de --hl de
# German news
python3 scripts/search.py -q "Nachrichten aus Berlin" --mode current --gl de --hl de
# French product research
python3 scripts/search.py -q "meilleur smartphone 2026" --gl fr --hl fr
Output Format
The script streams a JSON array. The first element is metadata, the rest are results with full extracted content:
[{"query": "...", "mode": "default", "locale": {"gl": "world", "hl": "en"}, "results": [{"title": "...", "url": "...", "source": "web"}]}
,{"title": "Page Title", "url": "https://example.com", "source": "web", "content": "Full extracted page text..."}
,{"title": "News Article", "url": "https://news.com", "source": "news", "date": "2 hours ago", "content": "Full article text..."}

Edge Cases
- If trafilatura cannot extract content from a page, the result falls back to the search snippet.
- Some sites block scraping entirely — the snippet is all you get.
- If zero results are returned, the script exits with
{"error": "No results found", "query": "..."}.
- The Serper API key is loaded from
.env in the skill directory. If missing, the script exits with setup instructions.
