# Unique User Memory

Persistent per-user memory for Unique AI agents.

`unique_user_memory` stores a compact Markdown profile for each user and updates it after every agent turn. The profile is loaded before the next turn so the assistant can remember stable user context such as communication preferences, work context, expertise, recent topics, and open follow-ups.

## What It Does

The package provides:

- `UserMemoryConfig` - Pydantic configuration for the consolidation model, profile token budget, and memory folder.
- `load_user_memory(...)` - resolves the user's private memory folder, downloads `memory.md`, and enforces the configured token budget.
- `UserMemoryPostprocessor` - runs after the assistant response, consolidates the latest turn into the profile, and uploads the updated `memory.md`.

The memory file is intentionally small and structured. It is rewritten as a full Markdown profile rather than appended to as an event log.

## Lifecycle

1. The orchestrator enables memory when `space.allow_user_memory` is true.
2. `load_user_memory(...)` resolves the pre-provisioned root folder, ensures a private child folder for the current user, and downloads `/user-memory/<user_id>/memory.md` if it exists.
3. The loaded memory text is passed into the agent context for the current turn.
4. `UserMemoryPostprocessor` runs after the assistant response.
5. The package asks the configured language model to either return `NOOP` or a complete rewritten profile.
6. If the profile changed, `memory.md` is uploaded back to the user's folder with ingestion skipped and the content hidden from chat.

## Storage Model

Memory is stored in Unique content as Markdown:

```text
/<root_folder>/<user_id>/memory.md
```

By default, `root_folder` is `user-memory`. The root folder must already exist. The package creates the per-user child folder when needed.

## Profile Format

Profiles contain YAML frontmatter followed by fixed Markdown sections:

```markdown
---
user_id: user_123
schema_version: 1
last_updated: 2026-06-17T12:00:00+00:00
turn_count: 1

# User Memory

## Communication Preferences
- Prefers concise answers with concrete examples.

## Work Context

## Skills & Expertise

## Recent Topics

## Open Questions / Follow-ups

```

The consolidation prompt preserves the schema, keeps bullets short, and returns `NOOP` when a turn has no durable user facts.

## Configuration

Memory is activated by the orchestrator when `space.allow_user_memory` is true. `UserMemoryConfig` only configures how active memory is consolidated and stored.

```python
from unique_user_memory import UserMemoryConfig

config = UserMemoryConfig(
    max_tokens=2000,
    root_folder="user-memory",
)
```

| Field | Default | Description |
| --- | --- | --- |
| `language_model` | `DEFAULT_GPT_4o` | Model used to consolidate the latest turn into the profile. |
| `max_tokens` | `2000` | Maximum profile size. Must be between 500 and 8000 tokens. |
| `root_folder` | `user-memory` | Root KB folder that contains per-user memory folders. |

## Integration

Typical orchestration code loads memory before the agent loop and registers the postprocessor for the same turn:

```python
from unique_user_memory.user_memory import load_user_memory
from unique_user_memory.user_memory_postprocessor import UserMemoryPostprocessor

user_memory_state = await load_user_memory(
    event=event,
    config=config.agent.services.user_memory_config,
    logger=logger,
)

if user_memory_state is not None:
    user_memory_text = user_memory_state.text
    postprocessor_manager.add_postprocessor(
        UserMemoryPostprocessor(
            config=config.agent.services.user_memory_config,
            event=event,
            state=user_memory_state,
            logger=logger,
        )
    )
```
