From ac9f2d57457f0f8f6d85150e44b26acfb784e366 Mon Sep 17 00:00:00 2001 From: Jiangtian Feng Date: Tue, 9 Jun 2026 20:02:49 +0800 Subject: [PATCH 1/5] =?UTF-8?q?feat(sight):=20add=20ReactiveExporter=20for?= =?UTF-8?q?=20observe=E2=86=92act=20pipeline?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The first piece of dynamic orchestration in ANOLISA: agentsight can now react to observed events, not just record them. ReactiveExporter is a GenAIExporter that inspects each LLM call event for critical signals and triggers actions: - Critical interruption (crash/OOM/SIGKILL in error) → spawn ws-ckpt checkpoint to save workspace state automatically - Token waste advisory (>50K input with no prompt caching) → log a recommendation Design: - Non-blocking: export() does try_send on a bounded channel (cap 32); background thread owns the receiver and runs ws-ckpt - Timeout-protected: try_wait poll loop with 10s deadline + kill, so a stuck ws-ckpt never blocks the thread or Drop - Debounced: at most 1 checkpoint per configurable interval (default 30s), preventing storm-triggered cascades - Graceful: if ws-ckpt is not installed, new() returns None and no exporter is registered (zero runtime cost) - Default disabled: requires explicit config to activate Config (agentsight.json): { "reactive": { "enabled": true, "debounce_secs": 30, "workspace": "/root" } } Tested: 8 unit tests (detection, advisory, disabled, integration with real ws-ckpt spawn + timeout + debounce + clean Drop), full 546-test regression, ECS E2E (registration confirmed, zero false positives on normal traffic, integration test passes).

When an agent exceeds 200K input tokens in one hour with no prompt caching, logs a one-time actionable advisory. Debounced per-agent per-hour. Replaces the old per-call 50K check_advisory (too aggressive, no state) with the cumulative approach (more accurate, fewer false positives).

Changes: - Add ReactiveNotifier (lightweight, Clone, Send+Sync) holding a SyncSender clone. ReactiveExporter::new() now returns the tuple (Self, ReactiveNotifier). - Store reactive_notifier on AgentSight struct. - Call notify_interruption("retry_storm") after RetryStorm insert (guarded by exists_for_conversation dedup — fires at most once per conversation). - Call notify_interruption("dead_loop") after DeadLoop insert (guarded by should_detect + LoopDetector.detect — fires only on genuine new pattern detection). Both calls are non-blocking (try_send), properly guarded against duplicates, and debounced by the background thread (30s default).
