ailinter gives AI coding assistants a safety checklist. Before your AI writes a single line — and after — it evaluates the file and tells the AI whether to Go Ahead or Stop & Refactor. Three scanners in one: 20 code quality detectors (0-100 score), 269 secret detection rules, 58 vulnerability patterns. Runs as an MCP server — integrates with Claude Code, Cursor, OpenCode, and GitHub Copilot. 15MB Go binary, zero dependencies, MIT licensed.
