Put the control flow in code, not in the prompt
Sequencing belongs in a script and judgement in the model. One routine commit cost 180k tokens as reasoning and seconds as bash. Here is the line.

A hinge is a physical object, and your layout should know where it is
Foldables give two things a resize doesn't: a posture and a hinge with real coordinates. Handling them well means avoiding the seam and using tabletop mode, not just supporting a new width.
Where to put the human
Gate placement for autonomous agents. Reversibility is the criterion, not confidence, and the consent surface matters as much as the question.
MCP, or a shell script? The honest comparison
Decided on concrete cases rather than preference. Where a protocol server earns its keep, where a script wins, and the failure that shows up unattended.
I swept the parameter instead of arguing about it
A threshold argument settled by measuring four values over the real corpus. The knee, the trade that stops paying, and why the numbers go in the comment.
The same rule in two files is how agent-written code drifts
A protected-path list was typed by hand and had drifted nine entries behind reality. Derive the list instead of copying it, and gate the copies you keep.
One level of fan-out, and why that is enough
A subagent cannot delegate, so the top session is the only scheduler. Designing around that, and why a barrier between stages costs more than it looks.
The prompt is not the artifact — the runtime is
A behaviour defect belongs in the command's runtime file, not in better instructions next time. What to edit, how to lock it, and where that stops working.
429 is not an error, it is a schedule
Transient and terminal failures need opposite responses and look identical. How to tell them apart, and why partial progress must be persisted before it is believed.
A gate that fixes what it finds
An auto-healing loop must fix the source, never the symptom, and must never edit the thing that found the problem. Confidence floors and bounded rounds.
Six guardrails that stop my AI agent mid-command
Six PreToolUse hooks that refuse an agent's command before it runs. What each one caught, and why a guard the agent can talk its way past is not a guard.
Skills, tools, and the difference that matters
Progressive disclosure across four tiers: what must be loaded to decide, what loads to execute, and what should never load unless someone asks for it.
