The next generation of great managers will not be defined by headcount or title. They will be defined by how well they wield the tools.
Claude Code, Gemini CLI, Codex — these are now part of the working environment for technical teams. The managers who are fluent with them move faster, answer harder questions with fewer hand-offs, and ship more with the same team. The ones who are not get outrun by someone more junior who simply picked up the toolkit first.
That gap is not theoretical. It is active, and it widens every cycle.
What fluency actually means
This is not a claim that managers have to learn to code. It is a more specific and more useful point: knowing what the tools do, where they break, how to aim them at a real problem — and being accountable for the result. That is the skill. It is distinct from programming, and it is learnable by any engineer who already thinks rigorously about process.
These tools are force-multipliers for expert teams, not shortcuts that bypass expertise. An engineer who understands die-attach process windows and can also direct an agentic tool to analyze a build dataset is more capable than either role in isolation. The engineering judgment drives the tool; the tool expands what that judgment can reach in a day.
What it looks like in practice
- Faster iteration on hard questions. Analysis that previously required hand-offs across multiple people or days of data work gets compressed. The bottleneck shifts from “getting the data” to “asking the right question.”
- Higher output from a smaller team. A fluent small team does not merely match a larger unfluent team — it consistently out-executes it on time-sensitive, technically complex work.
- Faster answers to customers. Quotes, build status, and technical responses arrive faster because the engineer can move from raw data to a clear answer without a support chain behind them.
A proof point from the shop floor
At Heisler, we design and manufacture advanced semiconductor packaging, and we build our own automation on top of these tools. It is a data-driven system, in active development, that lets a small expert team handle the breadth of work that would otherwise require a much larger headcount. It is not magic. It is applied engineering discipline, extended by tools that make expert engineers faster.
The bar does not hold at its current level. It rises. The teams that treat fluency with agentic tools as a real competency — one worth developing deliberately, not delegating indefinitely — will set the pace. The ones that defer that decision will find themselves catching up to a moving target.
“The best next-generation managers will be the ones who know how to wield the toolkit — not the ones who hand it to someone else.”
