pi-timestamp

Shows timestamps for user input and agent completion timing. Requires pi >=0.81.1.

What it does

• User input: Shows Sent HH:MM:SS as a dim status line in the chat display after each user message
• Agent completion: Shows Done at HH:MM:SS · duration as a dim status line in the chat display after each agent turn (e.g., Done at 14:32:05 · 3.2s)
• Session/runtime summaries: Shows accent-colored summaries when switching sessions and at final Pi exit, including start/end times and durations. The final summary includes the complete Pi process runtime and every session interval.

All timestamps and summaries are display-only — session-switch summaries render in Pi's UI and the final runtime summary prints after Pi restores the terminal in TUI mode. They never enter the LLM context.

Display behavior

Timestamps appear inline in the chat display, similar to Pi's built-in tool timing lines such as Took 1.9s. They are not appended to the session as user or custom messages, so they do not pollute the model context.

Installation

pi install npm:@hk_net/pi-timestamp

Or copy manually:

mkdir -p ~/.pi/agent/extensions
cp packages/pi-timestamp/timestamp.ts ~/.pi/agent/extensions/timestamp.ts

Duration measurement

Captured from agent_start (when the model starts processing) to agent_end (when all tool calls and model processing are done).
