autourgos-memory 1.0.2

Base memory interfaces for Autourgos agents — BaseMemory, MemoryMessage, Document, BaseRetriever.

autourgos-memory

Base memory interfaces for Autourgos agents.

This is the foundation package — it defines the abstract interfaces (BaseMemory, BaseRetriever, MemoryMessage, Document) that all concrete memory implementations use. Install it on its own, or install one of the concrete packages that depend on it.

---

Install

# Base interfaces only
pip install autourgos-memory

# Or install concrete implementations individually
pip install autourgos-buffer-memory    # in-memory ring buffer
pip install autourgos-local-memory     # JSON file + SQLite
pip install autourgos-semantic-memory  # TF-IDF keyword retrieval
pip install autourgos-summary-memory   # LLM-compressed rolling summary
pip install autourgos-token-memory     # token-bounded buffer

Memory types at a glance

Package	Class	Best for
autourgos-buffer-memory	RuntimeShortTermMemory	Fast in-memory buffer, message-count bounded
autourgos-buffer-memory	ConversationBufferMemory	Unbounded in-memory buffer
autourgos-local-memory	LocalShortTermMemory	Disk persistence via JSON file
autourgos-local-memory	SQLiteMemory	Disk persistence via SQLite, concurrent-safe
autourgos-semantic-memory	KeywordMemory	TF-IDF retrieval of relevant past context
autourgos-summary-memory	SummaryBufferedMemory	LLM-compressed history to save tokens
autourgos-token-memory	TokenBufferedMemory	Token-budget bounded buffer

---

Quick start (with concrete packages installed)

RuntimeShortTermMemory is soft re-exported from autourgos_memory — it only resolves if autourgos-buffer-memory is also installed:

pip install autourgos-memory autourgos-buffer-memory autourgos-openaichat

from autourgos_memory import RuntimeShortTermMemory  # requires autourgos-buffer-memory installed
from autourgos_react_agent import ReactAgent
from autourgos_openaichat import OpenAIChatModel

my_llm = OpenAIChatModel(model="gpt-4o-mini")  # needs OPENAI_API_KEY set
memory = RuntimeShortTermMemory(max_messages=20)
agent  = ReactAgent(llm=my_llm, memory=memory)
result = agent.invoke("What did I ask you last time?")

Base interfaces

MemoryMessage

from autourgos_memory import MemoryMessage
from datetime import datetime, timezone

msg = MemoryMessage(role="user", content="Hello", timestamp=datetime.now(timezone.utc))
print(msg.to_dict())
# {"role": "user", "content": "Hello", "timestamp": "2024-..."}

Allowed roles: user, agent, system, tool.

BaseMemory

Implement this to create your own memory backend:

from autourgos_memory import BaseMemory, MemoryMessage

class MyCustomMemory(BaseMemory):
    def add_user_message(self, content: str) -> MemoryMessage: ...
    def add_agent_message(self, content: str) -> MemoryMessage: ...
    def add_tool_message(self, tool_name: str, result: str) -> MemoryMessage: ...
    def format_for_llm(self, query: str = None) -> str: ...
    def clear(self) -> None: ...

BaseRetriever

Implement this to plug in your own vector database:

from autourgos_memory import BaseRetriever, Document

class MyVectorDB(BaseRetriever):
    def retrieve(self, query: str, top_k: int = 5) -> list[Document]: ...

Document

from autourgos_memory import Document

doc = Document(content="Paris is the capital of France.", score=0.92, source="wiki")
