Score: 7.8/10 (Innovation: 8, Technical: 8, Documentation: 8, Utility: 7)

Perspica is a Rust-based semantic diff tool that parses code with tree-sitter to separate mechanical noise from real changes, detect broken references and stale call sites, and compute a reading order for reviewers. It optionally adds LLM-powered intent grouping, risk scoring, and a 'Learn' tab that teaches the concepts behind a change, with a particular focus on reviewing code produced by coding agents.

Target audience: backend developers, code reviewers, engineering teams using AI coding agents, devops engineers
