Microsoft Agent Framework integration for Hindsight - persistent memory for AI agents

hindsight-agent-framework

Persistent long-term memory for Microsoft Agent Framework via Hindsight.

Microsoft Agent Framework is the successor to Semantic Kernel. This integration plugs Hindsight in as a context provider, so every agent run automatically recalls relevant memories into the agent's context and retains the conversation afterward — no MCP, and no tools the model has to remember to call.

Installation

pip install hindsight-agent-framework

✨ Recommended: Hindsight Cloud — sign up free, get an API key, and skip self-hosting.

Usage

from agent_framework.openai import OpenAIChatClient
from hindsight_agent_framework import HindsightProvider

agent = OpenAIChatClient().as_agent(
    name="assistant",
    instructions="You are a helpful assistant.",
    context_providers=[HindsightProvider(bank_id="user-123")],
)

session = agent.create_session()
await agent.run("Remember that I prefer vegetarian food.", session=session)
# ...later, even in a new process:
await agent.run("Suggest a recipe.", session=session)  # recalls the preference

Set your API key once via the HINDSIGHT_API_KEY environment variable, or pass api_key=/hindsight_api_url= to HindsightProvider. For self-hosting:

pip install hindsight-all
export HINDSIGHT_API_LLM_API_KEY=your-openai-key
hindsight-api  # http://localhost:8888

HindsightProvider(bank_id="user-123", hindsight_api_url="http://localhost:8888")

How It Works

Hook	Behavior
before_run	Recall memories relevant to the user's message and inject them as a ## Memories block in the agent's instructions.
after_run	Retain the user input + agent response so future runs build on them.

Memories live in a Hindsight bank (one per user/agent/session — you choose). Recall and retain are best-effort: a memory hiccup never blocks the agent.

Configuration

HindsightProvider(bank_id, ...) accepts: client, hindsight_api_url, api_key, budget (low/mid/high), max_tokens, context, tags, recall_tags, recall_tags_match, mission (creates the bank with a fact-extraction persona), auto_recall, auto_retain, source_id. You can also set process-wide defaults via configure(...).
