Ask for a Conservative Estimate
Works with ChatGPT · Claude · Copilot · Gemini
You can plan with realistic, cautious estimates.
The problem
Optimistic estimates set you up to run over on time and cost.
What this skill does
Ask the AI for a conservative estimate and the assumptions behind it. Estimates are not guarantees; for budgets or contracts, confirm figures with real quotes or a professional.
When to use it
- Use this when you are estimating time, cost, or effort.

Juni’s tip
Juni says: plans slip. A cautious estimate leaves room for reality.
