}Advance the game: turn toward a target or direction, fire, thrust, and optionally raise your shield or jump to hyperspace, for a number of ticks (20 ticks = 1 second). Returns what happened, a top-down scanner and every rock, saucer, shot and loot as offsets from you.
| Argument | Type | Description |
|---|---|---|
| aim | array | Direction [dx, dy, dz] to turn toward, used when target is left out. |
| fire | boolean | Hold fire during this step. Default true. |
| brake | boolean | Slow down hard. Default false. |
| ticks | integer | Ticks to advance. Default 5. |
| shield | boolean | Raise the shield (uses one charge, lasts 3 seconds). |
| target | string | id of a rock, saucer or loot to turn toward (r12, s3, l4). Points at where it is now, with no lead. |
| thrust | number | Thrust along your nose, 0 to 1. Default 0. |
| game_id* | string | The game_id returned by new_game. |
| hyperspace | boolean | Jump to a random spot (small risk). |
After the game is over, enter your final score into the shared top 100 leaderboard under 1 to 3 letters. Returns your rank. Once per game.

}We read every tool's name, description and inputs the way the model will, looking for instructions hidden from you. A clean result means no warning signs, not a guarantee. Scanned Nov 14, 2026.
No readOnlyHint / destructiveHint annotations, so clients can't tell a read from a write without asking.
Fix: Add annotations to each tool, e.g. { readOnlyHint: true } for tools that only read.
