Does the description clearly state what the tool does and how it differs from similar tools?
The description is a noun phrase listing components ('ignition, focus, qualia, sync R, unity metrics, access history') with no verb indicating the tool's action. It doesn't explicitly state whether the tool retrieves, computes, or updates state, making the purpose ambiguous. It does list specific metric names, slightly distinguishing it from siblings, but the core action is missing.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
