Agentic coding is dead.
The AI agent discipline that replaced it requires something most teams haven't built yet..
The ones who figure it out first will widen the gap on everyone else.
Andrej Karpathy gave it a name earlier this year: Agentic Engineering.
Not "use an AI agent to write code faster." Something far more structured designing systems where AI agents plan, write, test, and ship under real human oversight.
The teams skipping this structure are producing AI slop. Code that looks right, handles no edge cases, and nobody can maintain six weeks later.
📌 Here's what agentic engineering actually looks like in practice:
1. Write specs before touching the agent
The agent doesn't know your codebase conventions, naming patterns, or business logic. A rules file tells it how your project thinks,before it writes a single line.
→ Use case: Onboarding a new module without breaking existing architecture
→ Tools: Claude Code, Cursor
2. Choose your review posture and stick to it
Two modes: watch the agent work and approve edits in real time, or let it run and review the final PR. Mixing them randomly is how codebases get messy fast.
→ Use case: Production features need "human in the loop." Internal tooling can go "agent first."
→ Tools: Devin, GitHub Copilot Workspace
3. Build test harnesses before scaling agent output
At agent speed, a 1% error rate causes real damage. Automated tests need to catch bad code before it merges, not after.
→ Use case: High-volume teams running 500 PRs weekly with quality control intact
→ Tools: Augment Code, Zencoder
4. Design for parallel agents, not a single session
Running multiple agents simultaneously requires clear task boundaries, isolated branches, and a merge strategy not just a bigger prompt.
→ Use case: One agent refactors auth, another builds the API layer, a third writes tests all at once
→ Tools: Cursor, Kilo Code
The AI agents are the workforce. Agentic engineering is the system they run on.
Teams winning right now aren't better at prompting. They built better rails first.
