Show HN: BlastRadar GitHub Action, automatic production risk scoring on every PR

BlastRadar released a GitHub Action that automatically scores every pull request for production risk on a scale of 1-10 and blocks merges if the score exceeds a configurable threshold (default 7). The action uses an Anthropic API key to analyze diffs and can also be tested via a web interface at blastradar.vercel.app.
