Struct CompactStrategy 

pub struct CompactStrategy {
    pub enabled: bool,
    pub threshold_percent: f32,
    pub summary_model: String,
    pub max_summary_tokens: u32,
    pub keep_coding_instructions: bool,
    pub custom_instructions: Option<String>,
}

Strategy for context compaction.

Controls when and how conversation history is summarized to fit within context limits. The keep_coding_instructions flag determines whether detailed coding information (code snippets, file changes, function signatures) is preserved in summaries.

This flag mirrors OutputStyle::keep_coding_instructions for consistency.

Fields

enabled: bool

threshold_percent: f32

summary_model: String

max_summary_tokens: u32

keep_coding_instructions: bool

When true, includes detailed coding information in summaries:

• Full code snippets
• File names and changes
• Function signatures
• Error details and fixes

When false, creates a minimal summary focusing on:

• Primary request and intent
• Key decisions made
• Current work status
• Next steps

This mirrors OutputStyle::keep_coding_instructions for API consistency.

custom_instructions: Option<String>

Optional custom instructions to append to the compact prompt. These are user-provided instructions for customizing the summary.

Implementations

impl CompactStrategy

pub fn disabled() -> Self

pub fn with_threshold(self, percent: f32) -> Self

pub fn with_model(self, model: impl Into<String>) -> Self

pub fn with_keep_coding_instructions(self, keep: bool) -> Self

Set whether to keep detailed coding information in summaries.

This mirrors the keep_coding_instructions flag in OutputStyle.

pub fn with_custom_instructions(self, instructions: impl Into<String>) -> Self

Set custom instructions for the compact prompt.

pub fn from_output_style(style: &OutputStyle) -> Self

Available on crate feature cli-integration only.

Create a CompactStrategy that inherits coding instruction preference from OutputStyle.
