Web (search + browse + cite + CDP)

Overview

Default to web search when info may have changed, is niche, or the user asks. Use web.run for queries; follow citation rules and prefer authoritative sources. If interaction with a live page is needed, start Chrome with the bundled CDP helpers (tools/start.js, nav.js, eval.js, pick.js, screenshot.js, click-link.js).

When to Use

  • User says search/browse/look up/verify.
  • Topics likely to change: news, prices, releases, schedules, policies, versions, CEOs, rankings, travel, recommendations.
  • Niche/uncertain terms or potential typos.
  • Need direct quotes/links/citations.
  • Need to click, navigate, or extract structured data from a live site (use CDP tools).

Core Pattern

  1. Clarify intent + recency if not given.
  2. Issue 1–3 targeted search_query calls (diverse terms/domains as needed).
  3. Open promising results; skim with find for key patterns (names, dates, numbers).
  4. Extract 3–5 load-bearing facts; ensure dates are explicit.
  5. Cite each non-obvious fact with citeturnX… immediately after the sentence.
  6. State assumptions; if data missing, say so briefly.
  7. If interaction is required, start Chrome and use CDP helpers (below) to click/navigate/screenshot.

Query Tips

  • Add qualifiers: site:docs.example.com, version numbers, region.
  • For names with ambiguity, include org or role.
  • For recency: set recency days on search_query when asking “today/latest”.
  • Run multiple queries in one search_query array to save turns.

Reading & Validation

  • Check publish date vs event date; prefer the latest credible source.
  • Cross-check at least two domains for important claims.
  • Avoid low-trust domains unless only source; if used, flag confidence.

CDP Browser Controls (Chrome DevTools Protocol)

  • Start Chrome with remote debugging on :9222
    ./tools/start.js          # fresh profile
    ./tools/start.js --profile # reuse your profile/cookies
    
  • Navigate current tab or open new tab
    ./tools/nav.js https://example.com
    ./tools/nav.js https://example.com --new
    
  • Evaluate JS in active tab
    ./tools/eval.js 'document.title'
    ./tools/eval.js 'document.querySelectorAll(\"a\").length'
    
  • Screenshot current viewport
    ./tools/screenshot.js
    
  • Pick elements interactively
    ./tools/pick.js "Click the submit button"
    
  • Click a known link/text
    ./tools/click-link.js "Submit"
    
  • All CDP scripts live in skills/web/tools/; ensure they’re executable.

Citations

  • Place after punctuation; avoid bold/italics/code fences.
  • Group multiple sources: citeturn2search1turn2open0
  • Cite every fact that isn’t obvious or could have changed since 2024.
  • Don’t paste raw URLs; citations render as links.

Output Style

  • Be concise; surface the answer first, then short context.
  • Include exact dates (e.g., “as of 2025-12-12”).
  • If unresolved, say what you tried and what’s missing.

Red Flags

  • Answering from memory when the topic is time-sensitive.
  • No dates on “latest/new/current”.
  • Failing to cite or citing irrelevant pages.
  • Over-long quotes; keep ≤25 words per source.
  • Ignoring conflicting sources—mention disagreement briefly.
  • Using CDP without starting Chrome on :9222 via tools/start.js.
  • Forgetting to give citations when summarizing CDP-derived content.
