io.github.brianfofficialPublished by GitHub account brianfofficialv0.6.2Updated Oct 24, 2026
Pull churn from Stripe, Postgres, MySQL, or pasted feedback. AI-ranked drivers + fixes.
The publisher's own server: check.tattoo: tattoo size and placement guide
Overview
RetentionCheck lets an assistant analyze customer churn from Stripe, Postgres, MySQL or pasted feedback and get AI-ranked churn drivers with suggested fixes.
- What you can do
- Analyze Stripe subscriptions and customers to surface churn drivers and suggested fixes. Run SQL churn analysis against Postgres or MySQL, choosing the dialect. Analyze pasted customer feedback text into AI-ranked churn reasons. Show an example analysis without needing an API key.
- When to use it
- Use it when you want to find why customers churn from Stripe, Postgres, MySQL or pasted feedback and get ranked drivers with suggested fixes. Suited to a quick diagnostic before planning retention work.
- Requirements
- Runs locally over stdio from an npm package, so Node.js is needed. analyze_churn, analyze_stripe_churn and analyze_sql_churn require ANTHROPIC_API_KEY; Stripe analysis needs STRIPE_SECRET_KEY; SQL analysis needs POSTGRES_URL or MYSQL_URL. Network access to the Anthropic API and to Stripe or the chosen database is required.
Installation
In SourceWeft
- Open RetentionCheck in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
