The five durable skills
AI made producing output almost free; judgment stayed scarce. These five skills close that gap - they transfer across every stack and every model, and they're the spine of everything I teach.
Specification - saying precisely what "good" looks like
The single highest-leverage skill. Most bad AI output traces back to a vague ask. Learning to write a crisp spec -- context, constraints, and what "done" means -- is the difference between delegating and gambling.
Decomposition - breaking ambiguity into checkable pieces
Big, fuzzy goals are where AI hallucinates and humans lose the thread. The skill is cutting a goal into units small enough to verify, then sequencing them. It's project management for non-deterministic collaborators.
Verification - building guardrails around a system that guesses
AI output is non-deterministic by nature, so responsible use means wrapping it in deterministic checks: tests, acceptance criteria, review, a source of truth. Engineers call this agentic coding - and it's the line between a demo that impresses and software you can actually ship and maintain. Everyone else needs their own version of it.
Extraction & reuse - seeing the repeatable pattern and naming it once
The senior-engineer move: notice when you're doing the same thing twice, factor it out, and reuse it instead of rewriting it. Abstraction is what keeps systems -- and AI workflows -- healthy as they grow. It's the difference between vibe-coded software that buckles as it scales and agentically-built software that holds up.
Taste & judgment - knowing what's worth doing, and when it's actually good
When production is cheap, the constraint becomes discernment. What deserves to exist? Is this draft genuinely good or just plausible? Taste used to be a nice-to-have. It's now the job - and the last word, after everything else is in place.
Better felt than read
Now feel them
Reading the names is the fast path; feeling them stick takes ninety seconds. Instruct a hyper-literal robot (played by Claude) to make a PB&J, watch it do exactly what you said - not what you meant - and all five skills land at once.
