| Segment | Meaning |
|---|---|
T1 |
Turn number |
0.186$ |
Total cost of the turn |
OUT |
Generated tokens (output) |
HIT |
Tokens read from cache (cache read) |
MISS |
Uncached input tokens (input) |
Colors follow the active theme (accent / muted / dim). Notifications are shown only in Pi's TUI, not in JSON or RPC modes.
Installation
pi install npm:@nerisma/pi-turn-usage-notifications
Or via settings.json:
{
"packages": ["npm:@nerisma/pi-turn-usage-notifications"]
}
How it works
The extension subscribes to the turn_end event. When a turn ends it reads the
usage off the assistant message (event.message.usage), which carries the cost
breakdown (cost.total) and the token counts (output, cacheRead, input).
usage is not declared on the message union type in pi's published types, so it
is read through a narrow local cast; the field is present on the assistant
message at runtime.
Each metric becomes a segment, formatted with formatTokens (e.g. 7.79K,
1.41M) and colored with the theme's ANSI codes. Empty segments are dropped: a
zero cost, or a turn with no cache activity, simply does not appear. The segments
are joined with a dim · separator and emitted as a single line through
ctx.ui.notify(line, "info").
