En bref
Agentic coding is writing software by directing an AI coding agent that plans, edits and runs code in a loop, instead of typing every line yourself. You describe the goal in plain language, the agent reads your files, proposes changes, edits across the codebase, runs the tests and reacts to the results, while you steer and review along the way. Agentic coding is the hands-on, day-to-day practice of building with coding agents like Claude Code, Codex CLI and Cursor. Agentic engineering is the broader discipline that wraps that practice in clear goals, verification and quality gates so the output is production-grade.
How agentic coding works
Agentic coding flips the usual ratio: the agent does most of the typing and you do the directing. You give it a goal and the context it needs, it works in a loop, and you review what it produces before it counts.
- You describe the goal in plain language, not in syntax.
- The agent reads the codebase, plans, edits across files and runs your tests.
- You review the plan and the diff and decide what ships.
Agentic coding vs vibe coding vs autocomplete
There is a spectrum of AI coding. Autocomplete suggests the next line as you type. Vibe coding leans on an agent but accepts the result by its behaviour without reading it, which is great for prototypes. Agentic coding sits where most real work happens: you direct an agent through a whole task and stay in the review loop. Done with discipline (clear goals, tests, verification) agentic coding becomes agentic engineering.
- Autocomplete: line-by-line suggestions while you type (for example Copilot).
- Vibe coding: prompt, accept and run without reading the code. Best for throwaway work.
- Agentic coding: direct an agent through a whole task and review its work. The everyday practice.
How to get good at agentic coding
The skill is not memorising syntax; it is writing precise specs, preparing context, and reviewing fast. Set up a repeatable agentic coding workflow: a CLAUDE.md that teaches the agent your rules, a plan-before-edit habit, automatic quality gates, and a clean repo the agent can navigate. If you want a structured path, an agentic coding course that takes you from your first shipped app through the modern app stack and agent-first practices beats picking it up ad hoc.
