Function TestKnowledgePlugin_DescribeCall

cli/plugins/builtin_knowledge_test.go:174–202

TestKnowledgePlugin_DescribeCall pins the spinner-label contract: short, human one-liners — never the static description or the raw JSON envelope, both of which overflow a terminal row and flood the screen via the spinner's single-line repaint.

(t *testing.T)

// both of which overflow a terminal row and flood the screen via the
// spinner's single-line repaint.
