# Mem0 Stats

Show session and lifetime memory statistics.

## Execution

### Step 1: Gather session stats

Run the session stats reporter:

```bash
SCRIPT_DIR="${CLAUDE_PLUGIN_ROOT:-${CODEX_PLUGIN_ROOT:-${CURSOR_PLUGIN_ROOT:-}}}/scripts"
python3 "$SCRIPT_DIR/session_stats.py" peek 2>/dev/null || echo "{}"
```

The `peek` command returns JSON without clearing the stats file (unlike `report`).

If the script returns empty or errors, note "No session data available" and continue.

### Step 2: Fetch lifetime stats from API

Call `get_memories` with:
- `user_id=<active_user_id>`
- `app_id=<active_project_id>`
- `page_size=100`

Count the returned memories. Group them by:
1. `categories[0]` (platform-assigned) — primary grouping
2. `metadata.type` (agent-assigned) — secondary if no categories
3. `created_at` date — for age analysis

Also run a `search_memories` call with `query="project"`, `limit=1` to measure round-trip latency (time the call).

### Step 3: Display

Print a minimal dashboard. No ASCII bar charts — use a clean table layout:

```
## mem0 stats

**Session** — 3 written, 5 searches, categories: decision, convention

**Project: my-project** — 55 memories, API: 84ms

| Category             | Count |
|----------------------|-------|
| decision             |    24 |
| convention           |    15 |
| anti_pattern         |     6 |
| task_learning        |     5 |
| user_preference      |     3 |
| session_state        |     2 |

**Age** — oldest: 2026-02-15, newest: 2026-05-23
  < 7 days: 5 · 7–30d: 12 · 30–90d: 10 · > 90d: 8

**Identity** — user: kartik · project: my-project · branch: main
```

**Display rules:**
- Category table: sort by count descending, omit categories with 0 memories
- Age: single line with dot-separated buckets, computed from `created_at`
- Session line: skip if no session data available
- If only 1-2 total memories, skip the category table — just show the count
- Keep everything compact — no decorative borders or filler

## Weekly digest mode

When invoked with `--weekly` (e.g., `/mem0:stats --weekly`), append a weekly
activity digest after the standard stats dashboard:

### W1: Fetch recent memories

Call `search_memories` in parallel with time-scoped queries:
1. `query="decisions made this week"`, `filters={"AND": [{"user_id": "<id>"}, {"app_id": "<pid>"}, {"created_at": {"gte": "<7 days ago YYYY-MM-DD>"}}]}`, `limit=20`
2. `query="bugs errors fixes"`, same time filter, `limit=20`
3. `query="patterns conventions learnings"`, same time filter, `limit=20`

### W2: Analyze

Merge by ID. Group into "New this week" by `categories[0]` or `metadata.type`.
Calculate: memories added last 7 days, most active categories, most active day.

### W3: Display

Append after the standard stats:

```
### This week (May 16 – May 23)

+12 memories — most active: Wednesday (5)

| Category      | New |
|---------------|-----|
| decision      |   5 |
| task_learning |   4 |
| bug_fix       |   3 |

**Highlights**
- <2-3 sentence summary of most important decisions/learnings this week>
```

### W4: Write digest file

Write to `~/.mem0/weekly-digest.md` (overwrite). Append one-line to
`~/.mem0/digest-history.log`:
```
<YYYY-MM-DD> | <project_id> | +<new_count> memories | top: <top_category>
```

### W5: Empty state

If no new memories in 7 days:
```
No new memories in the past week. Total: <N> memories in <project_id>.
```
