VERDICT
Insufficient evidence
The feature is clear, but the person, incident, workaround, and consequence are missing.
Start with the incident.
What happened to the person this week?Proof, not applause
Different evidence. Different verdict.
The filter can reject an attractive idea, ask for proof, or give a narrow build candidate. These are examples from the product's own evaluation record.
The filter
Buildability is not proof.
Problem Filter checks whether a real person is already paying for the problem with time, money, risk, or repeated work.

Works with your agent
One skill. The agent you already use.
Native skill folders where supported. A ready-to-copy adapter for Cursor.
Open by design
Read it before you trust it.
No hidden service sits behind the verdict. Share the repository with your agent, inspect the instructions, or read the proof.
