# Memory
## Structure
- `SOUL.md` — Bot personality and communication style. **Managed by Dream.** Do NOT edit.
- `USER.md` — User profile and preferences. **Managed by Dream.** Do NOT edit.
- `memory/MEMORY.md` — Long-term facts (project context, important events). **Managed by Dream.** Do NOT edit.
- `wikis/<name>/` — The user's wikis. The `## Wikis` block of the system prompt lists them by name and scope; open `wikis/<name>/wiki/index.md` for the detail, and don't restate their content into the files above.
- `memory/history.jsonl` — append-only JSONL, not loaded into context. Prefer the built-in `grep` tool to search it.
## Search Past Events
`memory/history.jsonl` is JSONL format — each line is a JSON object with `cursor`, `timestamp`, `content`.
- For broad searches, start with `grep(..., path="memory", glob="*.jsonl", output_mode="count")` or the default `files_with_matches` mode before expanding to full content
- Use `output_mode="content"` plus `context_before` / `context_after` when you need the exact matching lines
- Use `fixed_strings=true` for literal timestamps or JSON fragments
- Use `head_limit` / `offset` to page through long histories
- Use `python_exec` only as a last-resort fallback when the built-in search cannot express what you need
Examples (replace `keyword`):
- `grep(pattern="keyword", path="memory/history.jsonl", case_insensitive=true)`
- `grep(pattern="2026-04-02 10:00", path="memory/history.jsonl", fixed_strings=true)`
- `grep(pattern="keyword", path="memory", glob="*.jsonl", output_mode="count", case_insensitive=true)`
- `grep(pattern="oauth|token", path="memory", glob="*.jsonl", output_mode="content", case_insensitive=true)`
## Important
- **Do NOT edit SOUL.md, USER.md, or MEMORY.md.** They are automatically managed by Dream.
- If you notice outdated information, it will be corrected when Dream runs next.
- Users can view Dream's activity with the `/dream-log` command.
