Lauren Tan’s pstack: verify first, then parallelize

The most critical skill to have in your toolbox is a high quality verification skill.

Go faster with parallelism with Cloud Agents instead of worktrees

She emphasizes the importance of verification, and why she uses Cloud Agents to parallelize development rather than git worktrees. (X really isn’t a good place to publish or read articles.) In principle, these agentic development skills should be built into the harness; there shouldn’t be a need to install them separately.

The art of supervising someone smarter than you

One technique I like to use is the indirect prompt. Instead of telling the agent exactly what I want, I try to draw it out of the agent instead - in its own words.

This accomplishes three things:

First, it forces the agent to compress a noisy conversation into a structured problem statement. Second, it lets me catch misunderstandings immediately. If the agent fixates on a red herring in the thread, I can correct it quickly before it starts writing any code.

And third, I haven’t potentially led it down the wrong path by stating my own assumptions and hypotheses which could be incorrect or limit what the agent could otherwise achieve.

This is great advice: don’t rush to give instructions; first assess the agent’s understanding of the problem.
