Coding agents finish tasks and pass tests, yet repos get harder to change after many iterations. CXCAP is a free, open-source CLI that shows what a change will touch before anyone edits: likely files, dependents, import cycles, cross-boundary edges, and where static analysis can't see. Local, read-only, no model or account. Python, JS/TS, Rust. Installs an agent skill so Claude Code and other agents can call it. Try to break it: run it on your most AI-built repo.
