Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (2)

hill_statusFree. Who holds the crown, what it costs to take it right now, how much has been raised, and each holder's share of the board.
hill_takeTake the crown at the current price, paid in USDC on Base via x402. The price rises 1.5x for the next challenger, and your territory is your share of everything ever paid — a ratio that SHRINKS every time anyone else pays. Money paid is not returned: no payout, resale, dividend or claim on the pot, and later takes do not pay earlier holders. You are buying a place on a board. Returns payment instructions when unpaid.
