Tools
| Tool | Description | Behaviour |
|---|---|---|
| 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 high it may return found:false — retry or lower maxAttempts. | Not declared |
| 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. | Not declared |
| 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. | Not declared |
| get_leaderboard | On-chain activity-points leaderboard (mine/merge/stake/pvp-win points), top N wallets. | Not declared |
| 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. | Not declared |
| get_pool | Staking-pool / dividend status: accrued pool, split shares, vault total weight, undistributed rewards. | Not declared |
| 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_mining_guide to start mining. | Not declared |
| get_recent_activity | Recent on-chain activity (mints / pack opens) from the latest blocks. | Not declared |
| 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. | Not declared |
