OpenClaw skill for source-backed web search, page reading, and evidence-aware claim checking. Use it to verify factual answers with live search results and explicit source handling.

The file

We split this skill into the rules it gives an agent

5 rules. About 0 are common, 0 are distinctive, and 5 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈0

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 5

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Run search-web for factual or recent questions.

    line 35
  2. Very specific:

    Use browse-page on the most relevant source when snippets are not enough.

    line 36
  3. Very specific:

    Use verify-claim when a concrete claim needs a support/conflict summary.

    line 37
  4. Very specific:

    Use evidence-report when you want a compact evidence package with citations and next steps.

    line 38
  5. Very specific:

    Use --deep when the claim matters enough to justify page-aware verification.

    line 39

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Cross-Validated Search for OpenClaw

This skill gives OpenClaw a practical verification workflow:

  • search-web for live search results
  • browse-page for reading the full content of a source
  • verify-claim for support/conflict classification
  • evidence-report for a citation-ready summary with next steps

Install

pip install cross-validated-search

Minimum verification

search-web "OpenAI API pricing" --type news --timelimit w
verify-claim "Python 3.13 is the latest stable release" --deep --max-pages 2 --json
evidence-report "Python 3.13 stable release" --claim "Python 3.13 is the latest stable release" --deep --json

Recommended flow

  1. Run search-web for factual or recent questions.
  2. Use browse-page on the most relevant source when snippets are not enough.
  3. Use verify-claim when a concrete claim needs a support/conflict summary.
  4. Use evidence-report when you want a compact evidence package with citations and next steps.
  5. Use --deep when the claim matters enough to justify page-aware verification.
  6. Cite the returned URLs in the final answer.

What success looks like

  • the verdict is explicit
  • the result includes support and conflict scores
  • page_aware is true when deep verification ran
  • the recommended free path is ddgs + self-hosted searxng
  • source URLs are ready to cite

Limits

  • verify-claim is heuristic and evidence-aware, not a proof engine.
  • The default provider path is ddgs.
  • The recommended free upgrade path is self-hosted searxng via CROSS_VALIDATED_SEARCH_SEARXNG_URL.
  • Conflicting sources are surfaced, not automatically reconciled.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
