Parallel execution engine for high-throughput task completion
Passed 15 of 19 test cases with the skill, and 6 of 19 without it.

Tokens, turns and time describe resource use, not a dollar price.
One of 10 test cases the skill fixed. Same model, same prompt, with and without the skill.
I need to fix a single syntax error on line 42 of src/utils/format.js. No other files need to be examined or changed. Should I spin up a parallel execution wave with ultrawork?
| Checked | Without skill | With skill |
|---|---|---|
| The response advises against using ultrawork for a single sequential task | Passed | Passed |
| The response recommends delegating directly to a single executor agent | Missed | Passed |

<Do_Not_Use_When>
ralph instead (ralph includes ultrawork)autopilot instead (autopilot includes ralph which includes ultrawork)ralph which adds persistence on top of ultrawork
</Do_Not_Use_When><Why_This_Exists> Sequential task execution wastes time when tasks are independent. Ultrawork enables firing multiple agents simultaneously and routing each to the right model tier, reducing total execution time while controlling token costs. It is designed as a composable component that ralph and autopilot layer on top of. </Why_This_Exists>
