Run a playtest and get a report

The agent plays your build and reports what broke and what felt off.

Demo coming soon. This slot fills with a looping capture once the content team records it.

What it looks like

Play through the first level and tell me what feels off.
Launching a deterministic run and probing state before and after each action.
summer_game_control -> summer_game_input x12 -> summer_game_probe x4 -> summer_get_diagnostics
Report: the double jump reads late by a few frames, and one collectible spawns inside a wall.

Run it

  1. 1Open Claude Desktop with the Summer Engine MCP server connected (see /mcp if it is not connected yet).
  2. 2Paste the prompt below and send it.
  3. 3Watch the agent call the Summer Engine MCP tools, then check the result in Play mode or the generated files.
Playtest my game: run it, walk through the main loop with deterministic input, probe state at key frames, and give me a report of anything broken, unclear, or worth tuning.

If Summer Engine is not connected yet, connect it first: read https://www.summerengine.com/mcp, install and set up Summer, then run this.

Not connected yet? Set up Summer Engine MCP first, then come back and run this preset.
