NEW Boss mode: one idea, 10 workers
Describe it rough. Spark builds it right.
The desktop companion that turns a messy idea into a real Roblox game inside Studio. Claude keeps your exact words, a boss splits the work across 10 specialist workers, and every step is proven before it's called done.

BRIEF KEEPS YOUR WORDS

From a sentence to a shipped feature.
Spark sits next to Roblox Studio. You talk like a player. It works like a studio.

Say it rough
"A lava-rising round game with a tower to climb." Typos, half-ideas, a screenshot — all fine.

A brief that keeps your words
Asked, examples, hints and unclear bits are sorted. "Also" stays an addition. At most three sharp questions — each with a recommended answer.

A boss splits the work
Plan, contracts and lanes. Scout, coder, mapper, UI, VFX, sound and more work in parallel — one Studio turn at a time.

THE CREW
Ten specialists. One boss.
Each worker has a lane, the right model for its job and its own memory. The boss hands out task cards with DONE MEANS lines and won't merge without proof.
DONE MEANS PROVEN
It doesn't say "should work."
Every change ends with a verification matrix: what was verified, what needs a playtest, and what's still open. Guard hooks stop workers from editing Studio directly or committing on their own.
- Raycast map checker: reachability, traps, floating parts
- Feel probe prints jump height, airtime, accel and stop
- UI checked at four screen sizes before it ships
- Release gate blocks on any FAIL
