Does the description clearly state what the tool does and how it differs from similar tools?
The description names a specific resource (recent daily allocation decisions) and enumerates the returned fields (date, weights, rationale, receipt transaction), so the agent knows exactly what it gets. It does not, however, distinguish itself from near-siblings like get_todays_allocation, get_treasury_history, or get_recent_cycles, so the agent must infer the boundary.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
