ct CancellationToken

Returns

Task

CheckAllToolsAsync(CancellationToken)

Checks all installed JD.AI tools for updates and returns a structured plan.

public Task<AllToolsUpdatePlan> CheckAllToolsAsync(CancellationToken ct = default)

Parameters

ct CancellationToken

Parameters

stoppingToken CancellationToken

Triggered when StopAsync(CancellationToken) is called.

Returns

Task

A Task that represents the long running operations.
