Module session_memory_compact 

Session memory compaction.

Uses pre-extracted session memory as the summary instead of making an API call. Keeps recent messages above minimum thresholds and preserves API invariants.

Structs

SessionMemoryCompactConfig

Configuration for session memory compaction thresholds

SessionMemoryCompactResult

Result from session memory compaction

Functions

adjust_index_to_preserve_api_invariants

Adjust the start index to ensure we don’t split tool_use/tool_result pairs or thinking blocks that share the same message.id with kept assistant messages.

calculate_messages_to_keep_index

Calculate the starting index for messages to keep after compaction.

get_session_memory_compact_config

Get the current session memory compact configuration

has_text_blocks

Check if a message contains text blocks

is_compact_boundary_message

Check if a message is a compact boundary message

should_use_session_memory_compaction

Check if session memory compaction should be used

try_session_memory_compaction

Try to use session memory for compaction instead of traditional compaction. Returns None if session memory compaction cannot be used.
