Agents write code faster than any human can review it — so the knowledge that used to live in developers' heads has to live somewhere else. A hands-on walkthrough of the two big spec-driven methodologies: their workflows, their extensibility, and where both still leave you alone with the agent.

The jump from junior to mid is easy — make the code work. The path to senior is murkier: every company defines it differently. Here's a more reliable map — four steps (well, five, we start at zero) that move you toward senior no matter how your company draws the line.

Spoiler: more often than not, the problem isn't that you're bad at prompting. Below — why your agent misses the mark, and how I'm trying to fix it with SpecBuddy: a spec, a plan, and a review of every step, without leaving your IDE.
