ReleasePort's take

Light signal

editorial:auto 1mo

Playtest controls have been relocated to the Studio actions API. The Play Stop workflow now completes without requiring retries due to multiple plugin connections.

Why it matters: Moving Playtest controls under `manage_studio` APIs centralizes control logic, and eliminating retry requirements for stopping a Playtest improves reliability in version v2.8.1.

Summary

AI summary

Playtest controls moved to manage_studio APIs and stopping a Playtest no longer requires retries.

Full changelog

Features

Playtest controls now live under Studio actions — AI agents and direct MCP users should use manage_studio.play_start, manage_studio.play_stop, manage_studio.play_pause, manage_studio.play_resume, manage_studio.play_status, and manage_studio.run_test for Playtest workflows. The older system_info Playtest aliases are no longer the documented path, keeping system_info focused on read-only status and diagnostics.

Bug Fixes

Fix Play Stop cases that required a retry — Stopping a Playtest now handles cases where Roblox Studio creates multiple plugin connections after Play starts. WEPPY no longer relies on only one connection for Stop, and cleanup checks the Playtest status when it needs confirmation that Studio returned to Edit mode. This reduces cases where the AI asks Studio to stop but the test keeps running until you retry.

Breaking Changes

Removed `system_info` Playtest aliases; use new `manage_studio.*` APIs instead.
