Give your agent a post link, a saved article title, or a technical claim. It finds the article, checks the discussion for caveats, and produces an experiment card with a baseline, one change, metrics, and a decision rule. For example, you can check whether a pgvector index improves p95 latency while preserving recall on your own data. Connect daily.dev through MCP or configure a personal token locally, then ask: "Use Proof Before Merge to test the performance claim in this daily.dev post." The skill reads posts, bookmarks, and discussions and leaves execution to you unless you request it. ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"SoftwareApplication","name":"Proof Before Merge","description":"Turn a technical claim from a daily.dev post or bookmark into a reproducible experiment with a baseline, metrics, and a decision rule.","applicationCategory":"DeveloperApplication","url":"https://daily.dev/marketplace/ENfcrtStE","author":{"@type":"Person","name":"Chien Vu"},"dateModified":"2026-11-09T09:50:36.804Z"} ```
