Agentic Engineering: Moving Fast with Precision

Software engineering with autonomous coding agents is not about prompting an LLM to generate entire applications in one blind leap. That approach produces brittle codebases full of hallucinations and subtle regressions. ### The 80/20 Research and Planning Rule The highest leverage phase of any software project is the planning phase: - Deep dive research into API constraints, schema dependencies, and trade-offs. - Writing formal markdown specifications with explicit data models and strict edge case handling. - Reviewing implementation plans before a single line of application code is committed. When an implementation plan has zero ambiguity, subagents execute with mathematical precision and pass automated test suites on the first run.
