The spectrum of agentic coding — four maturity levels from vibe coding to staff-level quality¶
Insight: Agentic coding exists on a four-level maturity spectrum: (1) Vibe coding — let AI handle everything, no version control or security, suitable for throwaway projects; (2) Agentic coding with discipline — Git, file-level understanding, basic security and testing; (3) Agentic software engineering — verified tests, CI jobs, pre-commit hooks, function-level understanding; (4) High-quality software engineering — line-by-line understanding, self-reflection loops, AI-powered interactive code reviews, indistinguishable from handwritten staff-engineer code. Vibe coding with software engineering knowledge becomes "agentic software engineering" and eventually just "high-quality software engineering."
Detail: Key practices at each level: Level 2 adds Git and basic understanding. Level 3 adds CI jobs and pre-commit hooks (which solve many use cases people try to address with Claude Code hooks). Level 4 adds draft PRs for line-by-line review and "self-reflection loops" where asking the model "are you sure?" triggers deeper reasoning. The framework positions vibe coding not as a separate practice but as the entry point of a continuous skill progression.
