dsh-context-enhancement

Usage and verification

1. Start the Web profile and open or create a session.
2. Select 上下文增强 in the agent picker.
3. Work normally; task-state updates and context management are automatic.
4. Open Enhanced features in the session header to inspect enabled state and trigger counts.
5. Open Trajectory to inspect detailed pruning and compaction events.

Task state updates asynchronously after its event threshold is reached. A new session may report that an effect has not triggered yet even though the feature is enabled.

Configuration

Defaults live in cordis.patch.yml and can be replaced through a profile or home patch. A patch replaces the entire config object, so provide every required field.

Task-state provider

Field	Default	Purpose
provider / model	deepseek-official / deepseek-v4-flash	Model route for background state updates
minEvents	20	Eligible events required to start an update
maxEvents	200	Maximum events processed by one update
maxInputBytes	60000	UTF-8 input budget for one update
maxOutputTokens	4000	Background generation limit
timeoutMs	120000	Request deadline
maxInfraRetries	2	Additional retries for transient infrastructure failures
maxEntriesPerKind	50	Limit for each facts/decisions/constraints/risks collection
maxEntryBytes	4000	Limit for one state entry
maxListItems	40	Limit for one list field

task-state-prompt.maxBytes defaults to 8000 and bounds the state injected into a model request.

Compaction

contextual retains the official configuration vocabulary, including thresholdRatio, retainRatio, retainTokens, summarizationProvider, summarizationModel, maxTokens, compactionRetries, maxOverflowRetries, modelPolicies, and auto.

Tool-output reduction uses thresholdChars, headChars, and tailChars. Inspect real sessions in Trajectory before lowering these values. Aggressive thresholds increase processing frequency and may remove output needed for debugging.
