Method AddToolWarning

pkg/agent/agent.go:535–542

AddToolWarning records a warning generated while loading or starting toolsets. Warnings represent real failures the user should know about (a remote MCP server returning 4xx, an MCP binary missing, ...). Recoveries from a previous failure are intentionally not surfaced: the OAuth dialog and subseque

// a "now available" notification only adds noise.
func (a *Agent) AddToolWarning(msg string) {
	if msg == "" {

	a.warningsMu.Lock()
	defer a.warningsMu.Unlock()
	a.pendingWarnings = append(a.pendingWarnings, msg)
}

// DrainWarnings returns pending warnings and clears them.
func (a *Agent) DrainWarnings() []string {
