Show HN: I build a tool to encourage before reviewing code, review intents

Category: devtools

Tags: code-review, ai-agents, git-integration

Score: 8.3/10 (Innovation: 8, Technical: 8, Documentation: 9, Utility: 8)

Mainline is a Git-native memory layer for coding agents that records intent, decisions, and constraints before code changes, making it possible to review the rationale for AI-generated code before the diff. It addresses a critical gap in modern AI-assisted development by preventing agents from making context-blind edits, with a promising evaluation showing zero forbidden-list violations compared to code-first approaches.

Target audience: backend devs, devops, ai engineers
