pi-auto-session-name

A pi extension that gives every session a short, human-readable name so pi --resume shows a real description instead of the raw first message (which often starts with <system-reminder> context blobs and is useless for finding anything).

Features

• Automatic naming — after the first agent run settles, asks the model for a concise one-line title (up to ~14 words / 100 chars) summarizing the session, stored via pi.setSessionName().
• Stays current — refreshes the title every 8 user messages, so long-lived sessions stay findable as the topic evolves.
• Backfills old sessions — resuming an old unnamed session names it from existing history, gradually fixing your backlog as you open sessions.
• Never clobbers manual names — names set via /name, pi --name, or RPC are detected and respected, both in-process and across restarts (via a persisted ownership marker).
• Graceful fallback — if the model call fails, falls back to a cleaned + truncated version of the first user message.
• Cheap mode — use a smaller model for title generation via PI_AUTONAME_MODEL.

Install

# from npm (shows up on the pi package gallery)
pi install npm:@optomatica/pi-auto-session-name

# from git
pi install git:github.com/Optomatica/pi-auto-session-name

Or try it without installing:

pi -e npm:@optomatica/pi-auto-session-name

Usage

The extension works automatically — just start (or resume) a session and it gets named.

Commands:

• /autoname — regenerate the title now
• /autoname <text> — set a custom title (stops auto-renaming for this session)

Configuration

Env var	Default	Description
PI_AUTONAME_MODEL	active model	provider/model-id to use a specific (e.g. cheaper) model for title generation
PI_AUTONAME_DEBUG	unset	set to 1 to log debug output to stderr
