Interface: TokenBudgetOptions

Defined in: src/core/agent/window/types.ts:486

What tokenBudget({...}) accepts.

Example

const agent = Agent.create({ provider: anthropic(), model: 'claude-sonnet-4-5' })
  .window(tokenBudget({ thresholdTokens: 120_000 }))
  .build();

Properties

keepRecentTurns?

readonly optional keepRecentTurns?: number

Defined in: src/core/agent/window/types.ts:497

How many of the most recent turns are never dropped. Default 6.

thresholdTokens

readonly thresholdTokens: number

Defined in: src/core/agent/window/types.ts:493

Drop when the LAST call's adapter-reported input tokens exceed this.

REQUIRED, with no default — the same reason as .compaction(): only your model and your bill know the right number.
