/digital-marketing-pro:verify-claims

Purpose

Cross-check marketing claims against user-provided evidence data. Extracts all verifiable claims from content — statistics, percentages, rankings, awards, certifications, named citations, performance metrics, customer counts, and time-bound assertions — then matches each against an evidence file and classifies it as verified, partially verified, unverified, or contradicted. This command is the dedicated deep-dive for claim integrity, while /digital-marketing-pro:eval-content includes claim verification as one dimension of its broader quality assessment.

Marketing content that cites specific numbers, awards, or results without verified backing is a brand risk. Contradicted claims erode trust if caught by customers, journalists, or regulators. This command ensures every factual assertion in your content is backed by real data, clearly sourced, and defensible under scrutiny.

Input Required

The user must provide (or will be prompted for):

• Content with claims: The text to verify — provided inline, as a pasted block, or as a file path. Any marketing content that makes factual assertions: landing pages, case studies, press releases, ad copy, pitch decks, investor materials, product pages, or client reports
• Evidence file (optional but strongly recommended): A JSON file containing source data to verify against. Format: [{"claim": "descriptive claim text", "source": "data source name or URL", "date": "YYYY-MM-DD when verified", "verified": true/false, "value": "the verified number or fact"}]. Can be exported from GA4, CRM, sales data, certification bodies, or assembled manually. If not provided, the command operates in extraction-only mode and guides the user on creating an evidence file
• Specific claim to check (optional): A single claim to focus on instead of scanning the full content — useful for quick spot-checks on a particular statistic or assertion

Process

1. Load brand context: Read ~/.claude-marketing/brands/_active-brand.json for the active slug, then load ~/.claude-marketing/brands/{slug}/profile.json. Apply compliance rules for target markets (skills/context-engine/compliance-rules.md) — some industries and regions have stricter requirements for substantiating claims (financial services, healthcare, EU consumer protection). Also check for guidelines at ~/.claude-marketing/brands/{slug}/guidelines/_manifest.json — if present, load messaging restrictions that may define approved claims and prohibited assertions. Check for agency SOPs at ~/.claude-marketing/sops/. If no brand exists, ask: "Set up a brand first (/digital-marketing-pro:brand-setup)?" — or proceed with defaults.
