Run and trial
A run is one agent attempt on a task under a treatment. The task brings its files and machine. The treatment brings its assets. The agent is who attempts the work. See Core concepts. A trial is a repeat of the same inputs. Trials = 2 launches two runs with the same task, treatment, and agent. Each costs one run from your balance. Agents are not deterministic. Repeats turn a lucky or unlucky one-off into a pass rate you can trust.Pass rate and lift
Pass rate is the fraction of those repeated runs that passed, with a 95% confidence interval. More trials narrow the interval. Lift is the change in pass rate from a treatment versus the baseline. Positive lift means the treatment helped. Your skill, MCP server, CLI, or SDK made agents more successful.Matrix
Matrix lines up tasks, agents, and treatments. You see pass rate, lift, cost, tokens, and duration together. Use it to pick what works well and cheaply.
