AI Tips2

Delete stale AI instructions, rebuild from evidence

  1. Turn off your system prompt, skills, hooks, and custom instructions for a real task.
  2. Add an instruction only when the same mistake repeats, then retest before keeping it.
Prompt
Help me run an ablation test on my AI setup.

TASK:
[Describe a real task.]

GUARDRAILS:
[List the rules that cannot be violated.]

EXIT CRITERIA:
[Define exactly what “done” means.]

VERIFICATION:
[Explain how the result can be tested or inspected.]

Start without relying on my existing skills, hooks, memories, or detailed workflow instructions.

Complete the task, record where you struggle, and distinguish one-time mistakes from repeated failure patterns. Recommend a new instruction only when the same failure occurs repeatedly.

For every proposed instruction:
1. Explain the observed failure it fixes.
2. Write the smallest instruction that could fix it.
3. Retest the task with that instruction added.
4. Keep it only if the result measurably improves.

US GDP growth slows to 1.5% in Q2, but AI infrastructure spending props up the number

Growth missed the 1.8% forecast and fell from 2.1% the prior quarter; more than half of Q2 growth came from AI-related data-center investment, per Stripe's chief economist, even as consumer spending accelerated to 3.2% on tax refunds and a brief dip in gas prices.

The takeawayA live data point for any client budgeting conversation about how much of the current economy is genuinely new demand versus AI infrastructure spend, and the Fed is now weighing a possible September rate move.

Conversation starterHow much of our own growth story this year is real new demand versus AI infrastructure spend propping up the topline?

Tim Cook closes out his final earnings call as Apple CEO.

Apple beat on iPhone and Mac revenue, but softness in China and services, plus perceptions that Apple is spending less on AI than rivals, sent the stock lower in after-hours trading; John Ternus takes over as CEO on September 1.

The takeawayA textbook case of a leadership transition landing at the same moment as market doubts about AI strategy, useful if you're advising a client through a CEO succession of their own.

Conversation starterIf you were advising Apple's board, would you be worried the market is judging Ternus on an AI story he didn't write?

Amazon's cloud unit beats, and Amazon raises its AI capex guidance to $220 billion

AWS reported its fastest sales growth since Q4 2021, sending the stock up 9% after hours; investors shrugged off the higher 2026 AI spending target, up from $200 billion, given the strong cloud results.

The takeawayCloud and AI infrastructure budgets keep climbing at the biggest players, a useful benchmark when a client pushes back on their own rising AI infra line item.

Conversation starterIf Amazon just raised its AI capex guidance again, are we still comfortable with the budget assumptions in our own AI roadmap?

The takeawayNo direct relevance to your work, general awareness only.

Conversation starterDid you see Jersey Mike's average location does nearly triple Subway's revenue with a fraction of the locations? Says a lot about franchise economics.
