}

Session event “session.compaction_complete”. Conversation compaction results including success status, metrics, and optional error details

Fields

checkpoint_number: Option<i64>

Checkpoint snapshot number created for recovery

checkpoint_path: Option<String>

File path where the checkpoint was stored

compaction_tokens_used: Option<CompactionCompleteCompactionTokensUsed>

Token usage breakdown for the compaction LLM call (aligned with assistant.usage format)

conversation_tokens: Option<i64>

Token count from non-system messages (user, assistant, tool) after compaction

custom_instructions: Option<String>

User-supplied focus instructions provided to a manual /compact invocation. Omitted for automatic compaction and for manual compaction with no focus text.

error: Option<String>

Error message if compaction failed

messages_removed: Option<i64>

Number of messages removed during compaction

post_compaction_tokens: Option<i64>

Total tokens in conversation after compaction

pre_compaction_messages_length: Option<i64>

Number of messages before compaction

pre_compaction_tokens: Option<i64>

Total tokens in conversation before compaction

request_id: Option<RequestId>

GitHub request tracing ID (x-github-request-id header) for the compaction LLM call

service_request_id: Option<String>

Copilot service request ID (x-copilot-service-request-id header) for the compaction LLM call

status_code: Option<i64>

For failed compaction only: the HTTP status code of the compaction LLM call failure, when it carried one. Absent for successful compaction and for failures without an HTTP status (e.g. an empty model response or a transport error).

success: bool

Whether compaction completed successfully

summary_content: Option<String>

LLM-generated summary of the compacted conversation history

system_tokens: Option<i64>

Token count from system message(s) after compaction

tokens_removed: Option<i64>

Number of tokens removed during compaction

tool_definitions_tokens: Option<i64>

Token count from tool definitions after compaction
