Summary  
This chapter covers implementing data validation routines that ensure every assertion is backed by a reliable reference, flag missing or mismatched links, detect outdated or weak sources, and enforce appropriate confidence levels.

General domain of usage  
Academic research

Before completing the report, check that every important claim is supported by a reliable source. Claude should identify:

* claims without citations;
* citations that do not support the claim;
* weak or outdated sources;
* missing context or limitations;
* conclusions stated with too much certainty.

> ### Task
> 
> * Ask Claude to review the research brief and correct any unsupported or inaccurate claims.
> 
>   > **Review every claim and citation in the research brief. Flag unsupported claims, verify that each citation matches the evidence, and revise anything that is unclear, misleading, or stated with too much certainty.**

Build a complete AI-powered research system using Claude Code. You will learn how to turn a broad topic into focused research questions, create a structured plan, find and evaluate reliable sources, and organise evidence in a reusable workspace. Through practical AI Lab chapters, you will create source libraries, compare conflicting information, store findings in a research database, and produce clear research briefs with accurate citations. By the end of the course, you will have a repeatable Claude Code workflow that can be used for future research projects.

Learn what makes a research system reliable and how to prepare a structured workspace before collecting information. You will define research questions, set the scope of the project, and create a clear research plan for Claude to follow.

Learn how to find relevant information and judge whether a source is trustworthy. You will remove weak, outdated, and duplicate sources before organising the strongest results into a structured source library.

Turn collected sources into clear and usable evidence. You will extract key findings, compare sources that disagree, and build a research database that keeps claims, evidence, and source details connected.

Use the collected evidence to develop supported conclusions and create a concise research brief. You will review claims and citations for accuracy before turning the complete process into a reusable Claude Code workflow.
