Variable: approximateCounter

const approximateCounter: TokenCounter

Defined in: token-counter.ts:44

A fast, zero-dependency approximate token counter.

Uses the chars / 4 heuristic plus a small per-message overhead to account for chat framing tokens.

Good enough for budget checks and context-window guards. For exact counts, use a provider-specific counter (e.g. createTiktokenCounter).

#Example

import { approximateCounter } from '@agentskit/observability'

const tokens = approximateCounter.count(messages)
if (tokens > 120_000) trimOldMessages(messages)
