description: Deep Dream — automatic distillation from conversations to permanent memory
|
|
---
|
|
|
|
Deep Dream is the core consolidation mechanism of CowAgent's memory system, responsible for distilling scattered daily memories into refined long-term memory and generating dream diaries.
|
|
|
|
## Memory Flow
|
|
|
|
CowAgent's memory progresses through three stages from short-term to long-term:
|
|
|
|
```
|
|
Conversation context (short-term) → Daily memory (mid-term) → MEMORY.md (long-term)
|
|
```
|
|
|
|
### 1. Conversation → Daily Memory
|
|
|
|
When conversation context is trimmed or during the daily scheduled summary, the system uses LLM to summarize conversation content into key events, writing them to the daily memory file `memory/YYYY-MM-DD.md`.
|
|
|
|
Triggers:
|
|
- **Context trimming** — Trimmed content is summarized when turn or token limits are exceeded
|
|
- **Daily schedule** — Automatically triggered at 23:55
|
|
- **API overflow** — Emergency save of current conversation summary
|
|
|
|
### 2. Daily Memory → MEMORY.md (Distillation)
|
|
|
|
After the daily summary completes, Deep Dream automatically runs distillation:
|
|
|
|
1. **Read materials** — Current `MEMORY.md` + today's daily memory
|
|
2. **LLM distillation** — Deduplicate, merge, prune, extract new information
|
|
3. **Overwrite MEMORY.md** — Output the refined long-term memory
|
|
4. **Generate dream diary** — Record discoveries and insights from the consolidation
|
|
|
|
### 3. Role of MEMORY.md
|
|
|
|
`MEMORY.md` is injected into the system prompt for every conversation, keeping the Agent aware of user preferences, decisions, and key facts. Therefore it must stay concise — Deep Dream targets approximately 30 entries or fewer.
|
|
|
|
## Distillation Rules
|
|
|
|
Deep Dream follows these consolidation rules:
|
|
|
|
| Operation | Description |
|
|
| --- | --- |
|
|
| **Merge & refine** | Combine similar entries into single high-density statements |
|
|
| **Extract new** | Pull preferences, decisions, people, experiences from daily memory |
|
|
| **Conflict update** | When new info contradicts old entries, newer info takes precedence |
|
|
| **Clean invalid** | Remove temporary records, blank entries, formatting artifacts |
|
|
| **Remove redundancy** | Delete old entries already covered by more refined statements |
|
|
|
|
## Dream Diary
|
|
|
|
Each distillation generates a dream diary saved at `memory/dreams/YYYY-MM-DD.md`, written in a narrative style recording:
|
|
|
|
- Duplications or contradictions found
|
|
- New insights extracted from daily memory
|
|
- Cleanups and optimizations performed
|
|
- Overall observations
|
|
|
|
Dream diaries can be viewed in the Web console under "Memory → Dream Diary" tab.

|
## Manual Trigger
|
|
|
|
In addition to the automatic daily run, you can manually trigger distillation in chat:
|
|
|
|
```text
|
|
/memory dream [N]
|
|
```
|
|
|
|
- `N`: Consolidate the last N days of memory (default 3, max 30)
|
|
- Runs asynchronously in the background; you'll be notified in chat when complete
|
|
- Web notifications include clickable links to view MEMORY.md and dream diary
|
|
- Works without Agent initialization — can be used before the first conversation
|
|
|
|
<Tip>
|
|
After first deployment, it's recommended to run `/memory dream 30` once to distill all historical daily memories into MEMORY.md.

## Safety Mechanisms
|
|
|
|
| Mechanism | Description |
|
|
| --- | --- |
|
|
| **Skip on no content** | Distillation skipped when no daily memory exists, avoiding empty overwrites |
|
|
| **Input dedup** | In scheduled tasks, automatically skipped when input materials haven't changed |
|
|
| **Async execution** | Distillation runs in a background thread, never blocking conversation |
|
|
| **Sequential guarantee** | In scheduled tasks, daily flush completes before distillation starts |
|
|
| **No fabrication** | Prompt explicitly constrains consolidation to existing materials only |
|
