Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero parameters, and description coverage is 100% (vacuous). The description adds meaning by specifying that the tool lists 'repositories and plugin states,' which explains what data the agent will receive, even though there are no parameters to document. Baseline for 0 params is 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
