Struct CompactionConfig 

pub struct CompactionConfig {
    pub threshold_tokens: usize,
    pub retain_recent: usize,
    pub min_messages_for_compaction: usize,
    pub auto_compact: bool,
}

Configuration for context compaction.

Controls when and how context compaction occurs.

Example

use agent_sdk::context::CompactionConfig;

let config = CompactionConfig::default()
    .with_threshold_tokens(100_000)
    .with_retain_recent(20);

Fields

threshold_tokens: usize

Token threshold to trigger compaction. When estimated tokens exceed this, compaction is triggered. Default: 80,000 (conservative for 128K context models)

retain_recent: usize

Number of recent messages to keep intact (not summarized). These messages remain in full to preserve immediate context. Default: 10

min_messages_for_compaction: usize

Minimum messages before compaction is considered. Prevents compaction when conversation is still short. Default: 20

auto_compact: bool

Whether to automatically compact when threshold is reached. If false, compaction only occurs on explicit request. Default: true
