How to Split Roblox Work Between Assistant, Codex, and Studio Without Duplicating Changes
Assign one owner per contract. Use Assistant/Planning Mode for plan and project-aware decomposition, a coding harness for bounded repository edits, and Studio/manual work for visual judgment and final integration. Never give two agents the same unfinished system at once.

Split by ownership, not by convenience
A stable workflow might make Assistant own the reviewed task plan, Codex own a server module and tests, and a human own level layout or taste-sensitive polish. The exact tools matter less than a clear rule for who may change each interface.
Freeze interfaces before parallel work
If Codex is building an inventory service while Assistant is wiring UI, first freeze the inventory read contract. Without that, both tools may invent slightly different field names or event semantics and create integration work that erases the speed gain.
Use one integration gate
After each workstream finishes, integrate and playtest in Studio against the shared plan. Do not let one agent silently “fix” the other's output during integration; if a contract is wrong, update the contract and send the work back to the correct owner.
Keep taste and product decisions human-owned
Agents can suggest variants, but choices such as progression pacing, monetization feel, readability, and whether a mechanic is enjoyable should not be inferred from implementation convenience.
Working template
OWNERSHIP MAP PLAN / REQUIREMENTS: [...] SERVER CONTRACT: owner [...] CLIENT/UI CONTRACT: owner [...] SCENE / VISUAL: owner [...] FROZEN INTERFACES: [...] INTEGRATION GATE: tests + Studio playtest against original plan.
