Compaction configuration for context window management.
Fields§
§trigger_threshold: f64Threshold (0.0-1.0) at which to trigger compaction.
target_threshold: f64Target usage ratio (0.0-1.0) after compaction.
summary_prompt: StringPrompt for summarization.
keep_last_messages: usizeLegacy short-circuit used to skip local compaction for tiny histories.
retained_user_message_tokens: usizeTotal token budget reserved for retaining real user messages verbatim.
retained_user_messages: usizeMaximum number of recent user messages to retain verbatim.
always_summarize: boolForce local summarization even for short histories and providers with native compaction.
hierarchical: boolEnable hierarchical summarization (multi-level pyramid).
When true, compaction produces three tiers instead of a flat summary:
- Abstract: oldest turns compressed into 1-2 sentences
- Detail: middle turns summarized into a paragraph
- Verbatim: most recent turns kept as-is
When false (default), all old turns become a single flat summary.
auto_compact_suppressed: u8Auto-compaction suppression state. SUPPRESS_NONE (0) means compaction
is allowed; any other value gates automatic compaction until the
appropriate clearing event (success, model switch, etc.).
