Claude + Slack Knowledge Base Maintenance in n8n Workflow

Keep your Slack knowledge base accurate—automatically

This Claude + Slack Knowledge Base Maintenance workflow for n8n runs weekly to audit your knowledge base for stale articles, broken links, sentiment shifts, and factual/SEO issues—then uses Anthropic Claude to apply minor fixes or route major updates to Jira for SME review. Results are posted to Slack and logged to PostgreSQL.

What this workflow does

• Weekly scheduled audit: Sets configuration values like the knowledge base API URL, product version, staleness thresholds, and the Slack channel.
• Detects stale content: Fetches knowledge base articles via HTTP, calculates staleness signals (age, view trend, helpfulness), and filters articles exceeding your threshold.
• Validates links + reviews feedback: Extracts links from stale articles, checks them with HTTP HEAD requests, and analyzes recent article feedback stored in PostgreSQL using Claude sentiment analysis.
• Fact-checks and scores quality: Routes by severity, uses Tavily web search plus Claude to fact-check content and identify inaccuracies, then calculates an overall quality score.
• Performs SEO audit: Runs an Anthropic Claude SEO audit, stores audit history in PostgreSQL, and reports outcomes to Slack and an analytics API.
• Improves the articles safely: Uses Claude to classify each update as minor or major; it automatically rewrites and patches minor updates, while creating a Jira ticket for major changes.
• Finds knowledge gaps: Pulls top support-ticket topics from PostgreSQL, and uses Claude to propose new article titles.

Use cases

• SaaS teams keeping documentation current after releases and policy changes
