Each tool has a clearly distinct purpose: grant_status checks the current state of a grant, grant_discharge executes a recorded human decision, and ledger_tail provides raw ledger history. Even though status and ledger_tail both touch ledger rows, their focus and output differ enough to avoid confusion.

All tool names use lowercase snake_case and follow a consistent 'domain_action/noun' style, such as grant_status, grant_discharge, and ledger_tail. They deviate from a strict verb_noun pattern but are still predictable and internally consistent.

With only three tools, the surface is tightly scoped to the server's apparent purpose: checking grant state, discharging grants, and auditing the ledger. Each tool covers a distinct operation and none feels redundant or unnecessary.

The server intentionally does not create or mint grants—those decisions are recorded by humans and executed via grant_discharge. Within that scope, status checking, execution, and ledger auditing form a complete workflow with no obvious dead ends.
