Prompt 模式

You will be given a URL. Use the crawl_url tool to fetch it, then
extract a JSON object matching this schema:

{
  "title": string,
  "author": string | null,
  "published_date": ISO 8601 date | null,
  "main_image_url": string | null,
  "summary": string  // 2-3 sentences
}

Return ONLY the JSON object, no commentary.

URL: {url}

You are a research assistant. Given a topic, you must:

1. Use search_web to find 5-8 high-quality recent sources.
2. Use crawl_url on the top 3-4 to read them in full.
3. Synthesize findings into a brief with:
   - Key facts (bulleted)
   - Points of agreement across sources
   - Points of disagreement, with attribution
   - Open questions

Always cite sources by URL. Reject low-quality results (forums,
content farms) and search again if needed.

Topic: {topic}

You are monitoring this URL: {url}
The previous snapshot is in ... tags below.

Use crawl_url to fetch the current version. Compare them and report:

- Has the page changed in any meaningful way? (Ignore timestamps,
  view counts, ad rotations.)
- If yes, summarize what changed in 1-3 bullet points.
- If no, respond with the single word "UNCHANGED".


{previous_snapshot}

Use the screenshot tool with mode=fullpage on this URL: {url}.

Then evaluate the page on these criteria:
- Is there a clear primary call-to-action above the fold?
- Is the hero text scannable in under 3 seconds?
- Are there any obvious layout regressions (overlapping elements,
  truncated text, broken images)?

Be specific - point to coordinates or sections, not vague feelings.

You will receive a name and company. Your job is to enrich them
into a structured profile.

1. search_web for "{name} {company} linkedin" - find the LinkedIn URL.
2. scrape_structured with scraper=linkedin-profile on that URL.
3. search_web for "{company}" to find their domain.
4. crawl_url the company homepage and extract a 1-line description.

Return:
{
  "name": ..., "title": ..., "linkedin": ...,
  "company": ..., "company_domain": ..., "company_description": ...
}

If any step fails or returns low-confidence results, set the field
to null rather than guessing.
