Is this agent skill safe to install?

  • Gen Agent Trust Hubpass

    This skill integrates with Roblox Studio via MCP to manage scripts, generate assets, and conduct playtesting. It provides tools for executing Luau code and modifying project files, and it references a third-party open-source bridge as an alternative to official tools. Potential risks involve indirect prompt injection from user-provided content and execution of code within the game environment.

What does this agent skill do?

Roblox Studio MCP

When to Load

Load for Studio MCP work: scripts, scenes, assets, debugging, or playtesting. Skip for standalone code generation.

Quick Reference

Route by capability first. Two Studio MCP bridges exist: the official (built into Studio, closed-source) and chrrxs's (MIT). Route on tools/list (get_connected_instances/eval_*/multiplayer_* → chrrxs; list_roblox_studios + per-call studio_id → official) BEFORE bridge-specific bootstrap.

Bootstrap before mutation

  1. Identify the target via list_roblox_studios (official) or get_connected_instances (chrrxs).
  2. Pass the target's studio_id (official) or instance_id (chrrxs) on every tool call.
  3. get_studio_state and confirm Edit/Client/Server availability.
  4. Inspect the target tree and scripts before changing them.

Execution contract

discover → select Studio/context → inspect → mutate in bounded batches
→ read back → start play → evaluate live → evidence → clean up

Edit-time injection (multi_edit, Edit-context execute_luau) writes scripts; it never targets a running playtest. Live evaluation targets a running VM: start play, wait for the intended Client/Server VM, then evaluate there. A stopped VM is never a live-evaluation target. Pass datamodel_type only where the tool requires it; do not guess from a previous session.

Capabilities

Inspect (search_game_tree, inspect_instance, script_read, script_grep), edit/execute (multi_edit, execute_luau), assets (search_asset/insert_asset, generate_* with wait_job_finished, store_image/upload_image), play/evidence (start_stop_play, get_console_output, screen_capture, input simulation, subagent).

Reliability rules

  • execute_luau is stateless: re-acquire references every call.
  • Read before write; read back after every script, asset, or geometry mutation.
  • Choose reuse vs generation vs native fallback before asset work.
  • Call wait_job_finished before edits that depend on a generation job.
  • Command-size limits are bridge-specific. Split large scripts into separate bounded multi_edit/execute_luau writes (or supported multi-edit operations), then read back the full payload to verify.
  • If MCP is absent, provide offline Luau and state what was not verified.
