If you&#8217;re unsure about any aspect or if the report lacks necessary information, say &#8220;I don&#8217;t have enough information to confidently assess this.&#8221;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Use direct quotes for factual grounding:<\/strong>\u00a0For tasks involving long documents (>20K tokens), ask Claude to extract word-for-word quotes first before performing its task. This grounds its responses in the actual text, reducing hallucinations.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"border-width:1px;margin-top:var(--wp--preset--spacing--50);margin-right:var(--wp--preset--spacing--70);margin-bottom:var(--wp--preset--spacing--50);margin-left:var(--wp--preset--spacing--70);padding-top:var(--wp--preset--spacing--40);padding-right:var(--wp--preset--spacing--40);padding-bottom:var(--wp--preset--spacing--40);padding-left:var(--wp--preset--spacing--40)\"><strong>Example: Auditing a data privacy policy<br><\/strong><br>As our Data Protection Officer, review this updated privacy policy for GDPR and CCPA compliance.<br><br>&lt;policy><br>{{POLICY}}<br>&lt;\/policy><br><br>1. Extract exact quotes from the policy that are most relevant to GDPR and CCPA compliance. If you can&#8217;t find relevant quotes, state &#8220;No relevant quotes found.&#8221;<br>2. Use the quotes to analyze the compliance of these policy sections, referencing the quotes by number. Only base your analysis on the extracted quotes.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Verify with citations<\/strong>: Make Claude&#8217;s response auditable by having it cite quotes and sources for each of its claims. You can also have Claude verify each claim by finding a supporting quote after it generates a response. If it can&#8217;t find a quote, it must retract the claim.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"border-width:1px;margin-top:var(--wp--preset--spacing--50);margin-right:var(--wp--preset--spacing--70);margin-bottom:var(--wp--preset--spacing--50);margin-left:var(--wp--preset--spacing--70);padding-top:var(--wp--preset--spacing--40);padding-right:var(--wp--preset--spacing--40);padding-bottom:var(--wp--preset--spacing--40);padding-left:var(--wp--preset--spacing--40)\"><strong>Example: Drafting a press release on a product launch<br><\/strong><br>Draft a press release for our new cybersecurity product, AcmeSecurity Pro, using only information from these product briefs and market reports.<br><br>&lt;documents><br>{{DOCUMENTS}}<br>&lt;\/documents><br><br>After drafting, review each claim in your press release. For each claim, find a direct quote from the documents that supports it. If you can&#8217;t find a supporting quote for a claim, remove that claim from the press release and mark where it was removed with empty [] brackets.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Advanced techniques<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Chain-of-thought verification<\/strong>: Ask Claude to explain its reasoning step-by-step before giving a final answer. This can reveal faulty logic or assumptions.<\/li>\n\n\n\n<li><strong>Best-of-N verficiation<\/strong>: Run Claude through the same prompt multiple times and compare the outputs. Inconsistencies across outputs could indicate hallucinations.<\/li>\n\n\n\n<li><strong>Iterative refinement<\/strong>: Use Claude&#8217;s outputs as inputs for follow-up prompts, asking it to verify or expand on previous statements. This can catch and correct inconsistencies.<\/li>\n\n\n\n<li><strong>External knowledge restriction<\/strong>: Explicitly instruct Claude to only use information from provided documents and not its general knowledge.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Remember, while these techniques significantly reduce hallucinations, they don&#8217;t eliminate them entirely.
