/new does not rebuild system prompt, causing stale date #2559
Description
What do you want to change?
Fix: Rebuild the system prompt on /new so dynamic values (like the current date) are refreshed. Add two lines after agent.reset() in newSession():
this._baseSystemPrompt = this._rebuildSystemPrompt(this.getActiveToolNames());
this.agent.setSystemPrompt(this._baseSystemPrompt);This matches the pattern already used at startup and extension loading.
Why?
buildSystemPrompt() captures new Date() at call time and embeds Current date: YYYY-MM-DD into the system prompt. However, newSession() in agent-session.ts calls agent.reset() without rebuilding the system prompt.
If a user starts pi, leaves it running overnight, then uses /new, the agent still sees yesterday's date. This causes incorrect results for time-sensitive tasks (e.g., updating a "last modified" date in docs). This is especially problematic for documentation base agent coding workflows where I frequently keep pi running across days. The stale date leads to wrong timestamps in generated content.
