Content Consistency Validator

Overview

Checks content for tone, terminology, formatting, and structural consistency across multiple documentation sources (websites, GitHub repos, local docs). Generates read-only discrepancy reports with severity-classified findings and actionable fix suggestions including file paths and line numbers.

Examples

• Pre-release audit: Before tagging a new version, run the validator to catch version mismatches between your README, docs site, and changelog — e.g., the website says v2.1.0 but the GitHub README still references v2.0.0.
• Post-rebrand check: After renaming a product or updating terminology (e.g., "plugin" to "extension"), validate that all docs, landing pages, and contributing guides use the new term consistently.
• Onboarding review: When a new contributor flags confusing docs, run a consistency check to surface contradictory feature claims, outdated contact info, or missing sections across your documentation sources.

Prerequisites

• Access to at least two content sources (website, GitHub repo, or local docs directory)
• WebFetch permissions configured for remote URLs (deployed sites, GitHub raw content)
• Local documentation stored in recognizable paths (docs/, claudes-docs/, internal/)

Instructions

1. Discover sources — scan for build directories (dist/, build/, public/, out/, _site/), GitHub README/CONTRIBUTING files, and local doc folders:

   find . -maxdepth 3 -name "README*" -o -name "CONTRIBUTING*" | head -20
   ls -d docs/ claudes-docs/ internal/ 2>/dev/null

1. Extract structured data from each source: version numbers, feature claims, product names, taglines, contact info, URLs, and technical requirements:

   grep -rn 'v[0-9]\+\.[0-9]\+' docs/ README.md
   grep -rn -i 'features\|capabilities' docs/ README.md

1. Verify extraction — confirm at least 3 data points per source. If a source returns empty, check the Error Handling table before continuing.
2. Build comparison matrix pairing each source against every other (website vs GitHub, website vs local docs, GitHub vs local docs):

   diff <(grep -i 'version' README.md) <(grep -i 'version' docs/overview.md)

1. Classify discrepancies by severity:

• Critical: conflicting version numbers, contradictory feature lists, mismatched contact info, broken cross-references
• Warning: inconsistent terminolo
