Write the problem hypothesis
For [specific user], completing [job] is difficult because [missing capability], causing [measurable consequence].
You can name one user, one situation and one measurable consequence without proposing a feature.感谢大佬的教程，学完后自己做了一个乐高式组装harness的项目，分享出来共同学习

SOURCE EVIDENCE
Read original GitHub Issue ↗Start with what users actually said
Reporter context: llm-space 可以随意搭配 tool、特性（memory、 context compact等）创建harness并进行对比实验。 目前按照此课程实现了大部分特性，剩余特性正在开发。 <img width="1080" height="608" alt="Image" src="[link] /Excerpted from the public Issue. Read the complete thread before interpreting it.
Interview five affected users
- When did you last need this?
- What outcome were you trying to reach?
- What did you use instead?
- How often does this occur?
- What commitment would prove it matters?
Run the smallest experiment
Deliver the outcome manually or with a narrow prototype before building a reusable feature.
A user completes the real workflow and commits time, data, distribution or budget to repeat it.Make a build decision
- Build: repeated pain and active commitment
- Narrow: pain is real but the audience or job differs
- Stop: weak frequency or no behavioral proof
Why this brief exists
Information has value only when it changes action. This page turns one public signal into a bounded validation exercise. It is a research aid, not proof of demand, investment advice or a product recommendation.
