Content Consistency Validator

Overview

Cross-platform content consistency auditing for organizations maintaining messaging across websites, GitHub repositories, and local documentation. This read-only skill discovers content sources, extracts key messaging elements, and generates severity-graded discrepancy reports -- without modifying any files.

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/)
• Grep and diff access for comparing extracted content fragments

Instructions

1. Discover all content sources by scanning for website build directories (e.g., dist/, build/, public/, out/, _site/), GitHub README/CONTRIBUTING files, and local documentation folders.
2. Extract structured data from each source: version numbers, feature claims, product names, taglines, contact information, URLs, and technical requirements.
3. Build a cross-source comparison matrix pairing each source against every other source (website vs GitHub, website vs local docs, GitHub vs local docs).
4. Classify discrepancies by severity:
   • Critical: conflicting version numbers, contradictory feature lists, mismatched contact info, broken cross-references.
   • Warning: inconsistent terminology (e.g., "plugin" vs "extension"), missing information in one source, outdated dates.
   • Informational: stylistic differences, platform-specific wording, differing detail levels.
5. Apply trust priority when noting conflicts: website (most authoritative) > GitHub (developer-facing) > local docs (internal use).
6. Generate the final Markdown report with executive summary, per-pair comparison tables, a terminology consistency matrix, and prioritized action items with file paths and line numbers.
7. Save the report to consistency-reports/YYYY-MM-DD-HH-MM-SS.md.

Output

• Markdown report containing:
  • Executive summary with discrepancy counts grouped by severity
  • Source-pair comparison sections (website vs GitHub, website vs local docs, GitHub vs local docs)
  • Terminology consistency matrix showing term usage across all sources
  • Prioritized action items with specific file locations, line numbers, and suggested corrections
• Report file saved to consistency-reports/ with timestamped filename

Error Handling

Error	Cause	Solution
Website content unreachable	Deployed URL returns 4xx/5xx or local build directory missing	Verify the site is deployed or run the local build; check WebFetch permissions
GitHub API rate limit exceeded	Too many raw content fetches in a short window	Pause and retry after the rate-limit reset window; use authenticated requests
No documentation directory found	Expected paths (docs/, claudes-docs/) do not exist	Confirm correct working directory; specify the documentation path explicitly
Empty content extraction	Source page uses client-side rendering not visible to fetch	Use a local build output directory instead of the live URL
Diff command failure	File paths contain special characters	Quote all file paths passed to diff and grep commands

Examples

Example 1: Pre-release version audit

• Scenario: A new version (v2.1.0) ships but internal training docs still reference v2.0.0.
• Action: Run the validator across the website, GitHub README, and docs/ directory.
• Result: Report flags version mismatch as Critical, listing each file and line where the old version appears.

Example 2: Feature claim alignment after adding a new capability

• Scenario: The website announces "AI-powered search" but the GitHub README omits it.
• Action: Validator extracts feature lists from both sources and compares.
• Result: Warning-level discrepancy noting the missing feature mention in the GitHub README with a suggested addition.

Example 3: Terminology consistency check

• Scenario: The website uses "plugins" while local docs use "extensions" and GitHub uses "add-ons."
• Action: Validator builds a terminology matrix across all three sources.
• Result: Informational note with a recommendation to standardize on a single term, listing every occurrence.
