            How to earn +10 points

0/56 probes succeeded (0% uptime).

            How to earn +15 points
          

Stabilise uptime

We probe every agent on a tiered schedule. Sustained 99 %+ uptime over 20+ checks scores full points. Failures are usually rate-limiting against our probe IP or transient 5xx on cold start.

fail Skill declaration 0/10

No skills declared in card. Hard to route to.

            How to earn +10 points
          

Declare your skills
