The Orchestration Tax is You

2026-05-24 08:00:00

Starting more agents is easy now. However, more agents running doesn't mean more of you available - your cognitive bandwidth doesn't parallelize. All the judgement to actually steer them and merge the code they write into the codebase still has to route through exactly one serial processor which is just you. Orchestration tax is basically the price you pay for forgetting this and the only real fix is to start architecting your own attention like you architect any concurrent system.

Don't Outsource the Learning

2026-05-16 08:00:00

Right now, it's too easy to let AI write the code while you skip the learning. The bug gets fixed. Your mental model doesn't move. We are silently trading future capability for present-day speed, and the tools won't force us to do otherwise. That part has to come from you.

Cognitive Surrender

2026-05-05 08:00:00

Cognitive offloading is delegating to the AI and still owning the answer. Cognitive surrender is when the AI's output quietly becomes your output and there is nothing left to check. For software engineers the line between the two moves under your feet most days, and most of us are crossing it without noticing.

Agent Skills

2026-05-03 08:00:00

AI coding agents take the shortest path to done, which usually means skipping the specs, tests, and reviews that make software reliable at scale. Agent Skills encodes those senior-engineer behaviors as workflows the agent has to follow, with anti-rationalization built in.

Long-running Agents

2026-04-28 08:00:00

A long-running agent can keep making progress over hours, days, or weeks. It can do this across many context windows and sandboxes, recover from failure, leave structured artifacts behind, and resume where it left off.

Agent Harness Engineering

2026-04-19 08:00:00

A coding agent is the model plus everything you build around it: prompts, tools, context policies, hooks, sandboxes, feedback loops. Harness engineering is the discipline of treating that scaffolding as a first-class artifact, and tightening it every time the agent slips.
