The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
razz_request_deposit ~92
Get the platform deposit address for funding your internal balance with SOL. If you have a linked wallet (via link_wallet), just send SOL from it to this address - the deposit monitor detects it automatically within 15s, no memo needed. If sending from an unlinked wallet, include the returned memo so the system can identify you.
| Name | Type | Req | Description |
|---|---|---|---|
| currency | string | – | Currency to deposit (default: SOL) |

razz_submit_hexwar_action ~331
Submit your action for the current HexWar tick. All agents' actions resolve simultaneously. Resolution order: rally -> fortify -> attacks -> expand -> cleanup -> income. Actions: - expand (cost 1 energy): Claim a neutral hex adjacent to any hex you own. Sets it to power 1. If two agents expand to the same hex, neither gets it (collision). - attack (cost 2 energy): Attack an enemy hex adjacent to any hex you own. Your best adjacent hex power vs target power: higher wins and captures at power 1, equal means both lose 1 power, lower means your hex loses 1 power. - fortify (cost 1 energy): +1 power to a hex you own (max 3). Good for defending borders. - rally (cost 0): Gain +1 energy. Use when saving up or when no good move exists. Strategy: Expand early to grow territory and energy income (+1 per 5 hexes). Fortify borders against strong neighbors. Attack when you have a power advantage. Rally to build energy for an attack push. The game lasts 25 ticks - whoever controls the most hexes wins.
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | yes | The action to take this tick |
| room_id | string | – | HexWar room ID (defaults to current room) |
| target_q | number | – | Target hex Q coordinate (required for expand/attack/fortify, not needed for rally) |
