Struct CompressionConfig

Configuration for active context compression (#1161).

Fields

strategy: CompressionStrategy

Compression strategy.

pruning_strategy: PruningStrategy

Tool-output pruning strategy (requires context-compression feature).

model: String

Model to use for compression summaries.

Currently unused — the primary summary provider is used regardless of this value. Reserved for future per-compression model selection. Setting this field has no effect.

compress_provider: ProviderName

Provider name from [[llm.providers]] for compress_context summaries. Falls back to the primary provider when empty. Default: "".

probe: CompactionProbeConfig

Compaction probe: validates summary quality before committing it (#1609).

archive_tool_outputs: bool

Archive tool output bodies to SQLite before compaction (Memex #2432).

When enabled, tool output bodies in the compaction range are saved to tool_overflow with archive_type = 'archive' before summarization. The LLM summarizes placeholder messages; archived content is appended as a postfix after summarization so references survive compaction. Default: false.

focus_scorer_provider: ProviderName

Provider for Focus strategy segment scoring and the auto-consolidation extraction LLM call (#2510, #3313). Both are cheap/mid-tier tasks, so one provider suffices. Falls back to the primary provider when empty. Default: "".

high_density_budget: f32

Token-budget fraction for high-density content in density-aware compression (#2481). Must sum to 1.0 with low_density_budget. Default: 0.7.

low_density_budget: f32

Token-budget fraction for low-density content in density-aware compression (#2481). Must sum to 1.0 with high_density_budget. Default: 0.3.
