pi-session-autoname

Pi extension for naming sessions and herdr tabs.

Commands

• /auto-name: generate a session name from the current session context, apply it as the Pi session name, and rename the herdr tab when running inside herdr.
• /hname [name]: rename the current herdr tab. If no name is provided, it uses the current Pi session name, or a fallback label.

How /auto-name works

• uses the active Pi model (ctx.model)
• calls the model directly from the extension via Pi's model API (complete()), without spawning a nested pi process
• samples the visible session transcript using:
  • first 4 conversation messages
  • 4 middle messages
  • last 4 messages
• includes only conversation messages (user and assistant)
• excludes tool outputs
• renames the herdr tab to Loading... while the title is being generated

Install

Option 1: pi package

pi install /absolute/path/to/pi-session-autoname

Then reload Pi:

/reload

Option 2: local extension directory

cp -r pi-session-autoname ~/.pi/agent/extensions/

Then reload Pi:

/reload

Option 3: npm package

pi install npm:pi-session-autoname

Then reload Pi:

/reload

Usage

• /auto-name
• /hname
• /hname "my tab name"

Notes

• /auto-name requires an active model.
• If you are not in a herdr tab, only the Pi session name is updated.
• Herdr auto-rename avoids showing the fallback tab label while an auto-generated name is still pending.
