Own blockrun.ai? List it with your agent
Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.
- 14 of 60 routes have never been scored — the audition tests them for the first time.
- 9 routes are scoring below 50 — likely broken, mispriced, or returning the wrong shape.
- 4 routes are in the 50–74 band — working, but with room to climb.
- 25 routes are flagged by the verifier as failing or inconclusive.
