dsh-brief-session-title

DSH session titles in the sidebar tend to be full sentences — a verbatim echo like "Explain what JavaScript closures are" sits there, long and hard to scan. The root cause is simple: the official prompt's only length constraint is "aim for about 5 words," a soft target that models routinely overshoot, and "concise" is never concrete enough to act on.

dsh-brief-session-title does exactly one thing: it swaps the system prompt for four hard rules plus six correct-versus-incorrect example pairs. English output stays plain and direct; Chinese output adopts a compact classical-vernacular blend; verbs are banned because they are the skeleton of a sentence; the result is capped under five words. All official logic — first human message, streaming, fallback — stays untouched. On load the plugin shuts the official title provider down and registers itself so exactly one generator stays active, and on any error it falls back to the deterministic official title.

Built for heavy DSH users who open many sessions daily and want sidebar titles short enough to use as bookmarks: "JS闭包浅说," "游戏PRD," "Node memory leak" — instantly legible, never a paragraph in disguise.
