Mem0 Tour

Mem0 Project Tour

Show the user what mem0 has stored for the current project.

Cross-project mode

When invoked with --all-projects (e.g., /mem0-tour --all-projects or /mem0-tour --all-projects auth middleware), search across ALL projects:

1. Call get_memories with filters={"AND": [{"user_id": "<active_user_id>"}]}, page_size=200 — no `app_id` filter. 2. If a search query was also provided, run search_memories with query=<query>, filters={"AND": [{"user_id": "<active_user_id>"}]}, top_k=20 — again no app_id. 3. Group results by app_id first, then by category within each project. 4. Display:

   ## <app_id_1> (<N> memories) ← current
   **Architecture Decisions** — <memory content>
   ...

   ## <app_id_2> (<N> memories)
   ...

   <N> memories across <M> projects

5. Mark the current project with ← (current) in the heading.

If --all-projects is NOT present, use the standard single-project flow below.

Peek mode (compact search)

When /mem0-tour receives a search query argument (e.g., /mem0-tour auth middleware) WITHOUT --all-projects, run in peek mode — compact one-liner results:

1. Run 2 parallel search_memories calls:

• Broad: query=<query>, filters={"AND": [{"user_id": "<id>"}, {"app_id": "<pid>"}]}, top_k=10, rerank=true
• Targeted: query=<query>, filters={"AND": [{"user_id": "<id>"}, {"app_id": "<pid>"}, {"metadata": {"type": "decision"}}]}, top_k=5, rerank=true

2. Deduplicate by ID, display compact results:

   ## mem0 search: "<query>" (<N> results)

   1. [decision] Auth module uses JWT with RS256 keys (2025-05-15) [mem0:a3f8b2c1]
   2. [anti_pattern] Don't use symmetric HS256 — leaked in env (2025-05-10) [mem0:7e2d9f4a]
   3. [convention] All middleware in src/middleware/ (2025-05-08) [mem0:c4d5e6f7]

Format: <number>. [<type>] <content, 80 chars> (<date>) [mem0:<short_id>] 3. If no results: No memories matching "<query>" for project <project_id>.

If no query argument and no --all-projects flag, use the full tour flow below.

Execution

Step 1: Fetch ALL memories for this project

Call get_memories to fetch all memories for this project:

filters={"AND": [{"user_id": "<active_user_id>"}, {"app_id": "<active_project_id>"}]}, page_size=100

Step 2: Run supplementary semantic searches

In parallel, run these search_memories calls to get relevance-ranked results for key topics:

• query="architecture decisions design choices", filters={"AND": [{"user_id": "<id>"}, {"app_id": "<pid>"}]}, top_k=10, rerank=true
• query="bugs errors failures anti-patterns", filters={"AND": [{"user_id": "<id>"}, {"app_id": "<pid>"}]}, top_k=10, rerank=true
• query="project setup tooling conventions preferences", filters={"AND": [{"user_id": "<id>"}, {"app_id": "<pid>"}]}, top_k=10, rerank=true

Do NOT filter by `metadata.type` in these calls. The platform auto-assigns categories — filtering on metadata.type misses memories that were auto-categorized but don't have an explicit metadata.type.

Step 3: Merge and group

Merge all results by memory ID (deduplicate). For each memory, determine its group using this priority:

1. Platform `categories` field (array on each memory, auto-assigned by Mem0). Use the first category value. 2. `metadata.type` field (if present, set explicitly by hooks/agent). Use as fallback if no categories. 3. "other" bucket for memories with neither.

Map category names to display names:

Step 4: Display results

Sort groups by descending memory count. Display in compact tabular format:

First show the category summary table:

mem0 tour

Session (ses_abc123)  branch: main
Project: my-project  -  349 memories

Category                   Count
-----------------------------------------
tooling_setup                119
bug_fixes                     78
architecture_decisions        32
task_learnings                14
...

Then for each category (sorted by count descending), show memories as numbered one-liners. Truncate each memory to 100 chars max:

tooling_setup (119)
  1. User requires that no git commit or push be performed without explicit permission... 
  2. OpenCode plugins are loaded from ~/.config/opencode/plugins/ for global installation...
  3. Assistant determined that the symlink method for loading the Mem0 plugin was failing...
  ... and 116 more

bug_fixes (78)
  1. Fixed getAll filter format from flat object to AND-wrapped array for mem0ai TS SDK v3...
  2. Root cause of user_id mismatch: plugin derived kartik.labhshetwar from git email...
  ... and 76 more

Show top 5 memories per category by recency. If a group has more than 5, note ... and <N> more.

Skip empty groups entirely.

Step 5: Print totals

<N> memories across <M> categories
project: <project_id>  branch: <active_branch>

Identity - user: <user_id>  project: <project_id>  branch: <branch>

Step 6: Empty state

If zero memories found for this project, print:

No memories stored yet for project <project_id>.
Start working - mem0 captures learnings automatically, or use /mem0-remember to save something now.

Output formatting

IMPORTANT: Do NOT use markdown in your output. OpenCode TUI renders text verbatim - markdown like bold, ## headers, and | table | syntax appears as raw characters. Use plain text with indentation for structure. Use dashes for lists. Use spaces to align columns instead of markdown tables.
