## Tools (as reported by the server, not verified)

- `get\_collection\_stats`: Live collection statistics for Spirit Cards: total minted, max supply, current mint price \(ETH\), difficulty \(requiredBits/baseBits\), cooldown, merge fee, burned/forged counters, paused flag, chainId and contract.
- `get\_card`: Full profile of a Spirit Cards token by id: species, element, rarity tier, HP/ATK/DEF, and the deterministic on-chain seed. Works for any minted token id.
- `verify\_nonce`: Recompute the proof-of-work for a \(miner, nonce\) pair exactly as the contract does: work = keccak256\(chainId ‖ contract ‖ miner ‖ nonce\). Returns the hash, its leading-zero-bit count, the current requiredBits threshold, and whether it would be accepted on-chain.
- `get\_leaderboard`: On-chain activity-points leaderboard \(mine/merge/stake/pvp-win points\), top N wallets.
- `get\_pool`: Staking-pool / dividend status: accrued pool, split shares, vault total weight, undistributed rewards.
- `get\_recent\_activity`: Recent on-chain activity \(mints / pack opens\) from the latest blocks.
- `get\_project\_info`: What Spirit Cards is: the game, the five-node loop \(mine → merge → battle → stake → points\), the chain \(Robinhood Chain, CORE contract, explorer, ETH gas\), official links, the collection \(species / rarity tiers / battle elements\) and the key economy \(max supply, price step, fee split\). Call get\_mini
- `get\_mining\_guide`: Step-by-step guide to mine a Spirit Card: the exact proof-of-work rule, the live difficulty / price / cooldown / chip discount, where to get a miner \(browser at /mine, public CLI\), the exact contract call, and how to get a valid nonce with the find\_nonce tool.
- `find\_nonce`: Grind a proof-of-work nonce for a miner address so it can mint immediately: work = keccak256\(chainId ‖ core ‖ miner ‖ nonce\), using the live requiredBits threshold. Returns the first nonce whose work has at least requiredBits leading zero bits, within a \~20 s wall-clock cap. If the difficulty is hig
