Memory

Memory lets agents retain context across turns. AutoAgents exposes a MemoryProvider trait and includes a simple sliding‑window implementation.

Sliding Window Memory

SlidingWindowMemory stores the most recent N messages (FIFO). Use it when recent context is sufficient and you want predictable memory usage.

#![allow(unused)]
fn main() {
use autoagents::core::agent::memory::SlidingWindowMemory;
let memory = Box::new(SlidingWindowMemory::new(10));
}

Attach memory via AgentBuilder:

#![allow(unused)]
fn main() {
let handle = AgentBuilder::<_, DirectAgent>::new(agent)
    .llm(llm)
    .memory(Box::new(SlidingWindowMemory::new(10)))
    .build()
    .await?;
}

The ReAct executor automatically stores user/assistant messages and tool interactions in memory each turn.

Custom Memory

Implement MemoryProvider to support alternate strategies (e.g., vector‑store, summaries, persistence). Key methods:

• remember(&ChatMessage) — store message
• recall(query, limit) — retrieve relevant context
• clear() — reset
• size() / memory_type() — diagnostics

The trait includes convenience hooks for summarization and export/import if you need persistence.
