Lists all projects with stored memories for the current user, showing memory counts and last activity dates. Use when checking which projects have memories, comparing memory distribution across repos, or finding a specific project scope.

# Mem0 List Projects

Show all known project scopes for the current user.

## Execution

### Step 1: Fetch memories to discover app_ids

There is no dedicated "list projects" API endpoint. Discover projects by fetching
the user's memories across all scopes.

**Important:** A filter with only `user_id` triggers implicit null scoping — it
excludes memories that have a non-null `app_id`. Run two queries and merge:

1. **Null-scoped:** `get_memories` with `filters={"AND": [{"user_id": "<active_user_id>"}]}`, `page_size=200`
   — catches memories without `app_id`
2. **App-scoped:** `get_memories` with `filters={"AND": [{"user_id": "<active_user_id>"}, {"app_id": {"exists": true}}]}`, `page_size=200`
   — catches memories with any `app_id`

Run both calls in parallel. Merge results, deduplicate by memory `id`.

If either response indicates more pages, paginate (up to 1000 total).

### Step 2: Extract distinct projects

For each memory, determine project by:
1. Top-level `app_id` field (preferred)
2. `metadata.project_id` (legacy memories)
3. `metadata.project` (oldest format)
4. `"(unscoped)"` if none found

Group by resolved project name. For each project, count:
- Total memories
- Most recent `created_at` date
- Top 3 `metadata.type` values by frequency

### Step 3: Display

```
## mem0 projects

  <app_id_1>  <count> memories  (last: <date>) ← current
  <app_id_2>  <count> memories  (last: <date>)

<N> projects, <M> total memories
```

Mark current project with `← current`. Sort by memory count descending.

### Step 4: Empty state

If zero memories found:
```
No projects found. Run /mem0:onboard to get started.
