Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific verb and resource: 'Full detail for one programme by id', immediately distinguishing it from list_programmes and compare_programmes. It also enumerates what 'full detail' includes (routes, fees, processing, mobility, tax, path to citizenship, Mirabello score), so the agent knows exactly what this tool returns.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
