# 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
```bash
pip install cross-validated-search
```
## Minimum verification
```bash
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.
