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:
- Read materials — Current
MEMORY.md + today’s daily memory
- LLM distillation — Deduplicate, merge, prune, extract new information
- Overwrite MEMORY.md — Output the refined long-term memory
- 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:
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
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 |
