Data for context.compacting event (compaction starting).

Fields

reason: CompactionReason

Why compaction was triggered.

strategy: String

Strategy requested (may differ from strategy_used in the completed event).

messages_before: usize

Number of messages before compaction.

tokens_before: Option<u64>

Estimated or provider-reported input tokens before compaction.

bytes_before: Option<u64>

Serialized request-context bytes before compaction, when measurable.

trigger: CompactionTrigger

What triggered this attempt: context-window budget or cost pressure.

model: String

Model performing the compaction.

provider: Option<String>

Provider backend (e.g. “openai”), when known.

driver: Option<String>

Local driver identifier, when known.

budget_remaining_tokens: Option<u64>

Tokens of headroom remaining when the attempt started, when measurable.

source_sequence: Option<i64>

Source message sequence the attempt ran at, when known.

cache_read_tokens: Option<u32>

Cached input tokens read before compaction, when reported.

cache_creation_tokens: Option<u32>

Cache-creation tokens written before compaction, when reported.
