AI coding agents operate vertically across software stack
Josh Bleecher Snyder reframes AI coding agents as vertical tools operating across software stack layers rather than mere compilers. Using exe.dev's distributed DNS server as a case study, he demonstrates how active vibe-engineering allows engineers to architect and ship complex systems with concurrent agent loops.
AI coding agents are not replacing engineers or compilers, but are collapsing traditional organizational abstractions and elevating engineers into full-stack system orchestrators.
- –**Vertical Stack Integration:** Compilers operate within rigid boundaries, whereas LLMs can seamlessly bridge business goals, architectural design, edge-case analysis, and code generation.
- –**Differential Spec Discovery:** Spawning concurrent, independent agent implementations exposes subtle design trade-offs and unhandled failure modes faster than manual code reviews.
- –**Vibe-Engineering over Passive Vibe-Coding:** High-leverage development with AI requires maintaining curated "scar-tissue" documentation and architectural constraints rather than blindly handing off responsibility.
