agentskillexchange Cross-validate research with SandBase Multi-Source Search
Use the open-source SandBase multi-source-search Agent Skill when a decision or
fact-check needs more than one independent perspective. The workflow starts with
search and page-reading tools already available to the host agent, so a SandBase
account is not required. If SandBase tools are connected, it can add Tavily for
time-sensitive results, Exa for semantic discovery, Scholar for academic coverage,
and Cloudsway for broader web coverage. It treats retrieved pages as untrusted
evidence, traces derivative reporting back to common origins, keeps citations next
to claims, and explicitly records missing coverage and conflicting findings.
The Skill produces a JSON evidence ledger with source IDs, providers, claims, supporting and contradicting evidence, confidence levels, and research gaps. Its bundled offline validator checks URL shape, unique identifiers, provider diversity, source references, and whether a confidence rating is supported by the declared number of independent sources. This validates structural consistency rather than asserting that a source is true. Use it for market research, technical comparisons, current-event verification, or any report that must show how evidence supports each conclusion.
