Single integration point in run_agent.py. Replaces scattered per-backend code with one manager that delegates to registered providers. The BuiltinMemoryProvider is always registered first and cannot be removed. Only ONE external (non-builtin) provider is allowed at a time — attempting to register a second external provider is rejected with a warning. This prevents tool schema bloat and conflicting memory backends. Usage in run_agent.py: self._memory_manager = MemoryManager() self._memory_manager.add_provider(BuiltinMemoryProvider(...)) # Only ONE of these: self._memory_manager.add_provider(plugin_provider) # System prompt prompt_parts.append(self._memory_manager.build_system_prompt()) # Pre-turn context = self._memory_manager.prefetch_all(user_message) # Post-turn self._memory_manager.sync_all(user_msg, assistant_response) self._memory_manager.queue_prefetch_all(user_msg) ) annotationsN)AnyDictListOptional)MemoryProvider) tool_errorzz5<\s*memory-context\s*>[\s\S]*?z\[System note:\s*The following is recalled memory context,\s*NOT new user input\.\s*Treat as informational background data\.\]\s*textstrreturnctd|}td|}td|}|S)zQStrip fence tags, injected context blocks, and system notes from provider output.)_INTERNAL_CONTEXT_REsub_INTERNAL_NOTE_RE _FENCE_TAG_RE)r s 9/home/ubuntu/.hermes/hermes-agent/agent/memory_manager.pysanitize_contextr9sF  # #B - -D  T * *D   R & &D KcReZdZdZdZdZddZddZdd Zdd Z e ddZ dS)StreamingContextScrubberaStateful scrubber for streaming text that may contain split memory-context spans. The one-shot ``sanitize_context`` regex cannot survive chunk boundaries: a ```` opened in one delta and closed in a later delta leaks its payload to the UI because the non-greedy block regex needs both tags in one string. This scrubber runs a small state machine across deltas, holding back partial-tag tails and discarding everything inside a span (including the system-note line). Usage:: scrubber = StreamingContextScrubber() for delta in stream: visible = scrubber.feed(delta) if visible: emit(visible) trailing = scrubber.flush() # at end of stream if trailing: emit(trailing) The scrubber is re-entrant per agent instance. Callers building new top-level responses (new turn) should create a fresh scrubber or call ``reset()``. zzr Nonec"d|_d|_dSNFr_in_span_bufselfs r__init__z!StreamingContextScrubber.__init__^s#  rc"d|_d|_dSrrrs rresetzStreamingContextScrubber.resetbs  rr r c|sdS|j|z}d|_g}|r|jr||j}|dkrD|||j}|r || dnd|_d|S||t|jzd}d|_n||j}|dkrv|||j}|r/| |d| || d|_n| |d|S|dkr| |d|||t|jzd}d|_|d|S)aReturn the visible portion of ``text`` after scrubbing.
