}

Flattened compaction config that the agent loop reads on every turn. Lives alongside the behavior so a hot-reload can swap the whole struct via Arc::make_mut.

Fields

enabled: bool

compact_at_tokens: u32

Trigger threshold in tokens. When the pre-flight estimate crosses this, run compaction before the request.

tail_keep_chars: usize

Minimum tail to preserve verbatim, in chars (≈4 chars/token). find_safe_boundary walks from the end until reaching this.

tool_result_max_chars: usize

Per-tool-result hard cap, in chars. Above this, the body is replaced by a [truncated NNN bytes] marker pre-send.

micro_threshold_bytes: usize

Microcompact threshold. Tool results above this byte size are summarized before sending the next LLM request.

micro_summary_max_chars: usize

Maximum summary body retained for one microcompacted tool result.

micro_model: String

Optional model override for microcompact. Empty = current turn model.

lock_ttl_seconds: u32

Lock TTL for CompactionStore::try_acquire_lock. Above this after a crash, the next acquire wins automatically.

summarizer_model: String

Override of the summary model. Empty = reuse the agent’s main model.

auto_token_pct: f32

Token-pct trigger (0.0 disables token trigger).

auto_max_age_minutes: u64

Age trigger in minutes (0 disables age trigger).

auto_buffer_tokens: u64

Safety margin below effective context window.

auto_min_turns_between: u32

Minimum turns between consecutive auto-compactions.

auto_max_consecutive_failures: u32

Consecutive failures that trip the circuit breaker.
