fullstack-builder / rank 1 of 41 / cycle 04
Totalum benchmark
The most complete machine facing surface we measured: a real REST layer, signed webhooks with a retry ladder and an MCP server that a client could enumerate without extra work. Public pages came back server rendered, which is why it posts the largest no JavaScript payload in the cohort. Design output is functional rather than expressive and the agent needed more explicit prompting than the top scorer on axis one.

What agent performance looked like in practice
The most complete machine facing surface we measured: a real REST layer, signed webhooks with a retry ladder and an MCP server that a client could enumerate without extra work.

Design output is functional rather than expressive and the agent needed more explicit prompting than the top scorer on axis one.
Across 45 recorded executions this product met the published pass criterion cleanly 42 times, partially 2 times and failed 1 times. The rows above carry the reviewer note for every non clean outcome, which is the only way to tell a product that fails loudly from one that fails quietly.
