Struct ContextManagementConfig 

pub struct ContextManagementConfig {
    pub mode: ContextManagementMode,
    pub pressure_tokens: Option<u64>,
    pub rollover_tokens: Option<u64>,
    pub reserve_tokens: u64,
    pub finish_rounds: u32,
    pub target_tokens: Option<u64>,
}

Task-aware soft context bands, parsed from context_management.* keys.

Missing thresholds use window-aware defaults (200k: 140k/180k; 1m: 250k/400k). A single override adjusts the other default as necessary to keep pressure below rollover. These settings never override the host’s hard capacity or authorize tools, disclosure, or a session transition.

Fields

mode: ContextManagementMode

pressure_tokens: Option<u64>

Optional absolute token threshold; auto in config clears the override.

rollover_tokens: Option<u64>

Optional absolute token threshold; auto in config clears the override.

reserve_tokens: u64

Minimum remaining headroom before any model round. Default: 16,000.

finish_rounds: u32

Maximum extra Plan/WrapUp rounds after rollover becomes due. Default: 2. Zero disables extensions; phase reports cannot renew this allowance.

target_tokens: Option<u64>

Footprint a rollover successor aims for (system prompt + tool schemas + retained messages). None/auto = min(100,000, 2/3 of pressure). An explicit value must be positive and below the pressure threshold.

Implementations

impl ContextManagementConfig

pub const MAX_FINISH_ROUNDS: u32 = 8

pub const MAX_RESERVE_TOKENS: u64 = 1_000_000

pub fn validate(&self) -> Result<(), &'static str>

Validate independently of a model selection. Also call validate_for_window when the effective context window is known.

pub fn validate_for_window( &self, context_window_tokens: u64, ) -> Result<(), &'static str>

Threshold overrides must fit the effective window. The hard budget remains authoritative even when an override fits this validation.
