Forget

Mem0 Forget

Delete specific memories from mem0.

Execution

Step 1: Parse input

The user provides either:

• A search query: /mem0:forget auth module decisions
• A memory ID: /mem0:forget <memory_id>

If no argument, ask: "What should I forget? Provide a search query or memory ID."

Step 2: Find memories

If memory ID provided (looks like a UUID or hex string):

• Call get_memory with the ID to verify it exists.
• Show: Found: "<memory content first 120 chars>" (created <date>)

If search query provided:

• Call search_memories with:
• query=<user's query>
• filters={"AND": [{"user_id": "<active_user_id>"}, {"app_id": "<project_id>"}]}
• top_k=10
• Show numbered list:

  Found <N> memories matching "<query>":
  1. <content, 120 chars> (type: <type>, created: <date>) [ID: <short_id>]
  2. ...

Step 3: Confirm

Ask: "Delete which memories? Enter numbers (e.g., 1,3,5), 'all', or 'cancel'."

For a single memory ID, ask: "Delete this memory? [y/N]"

Never delete without confirmation. This is destructive.

Step 4: Delete

For each confirmed memory, call delete_memory with the memory ID.

Step 5: Report

Deleted <N> memories.

If any deletions failed, report which ones and why.

Undo recent writes

If the user says "undo last N memories" or "undo last write":

1. Read session stats to get recently written memory IDs:

   SCRIPT_DIR="${CLAUDE_PLUGIN_ROOT:-${CODEX_PLUGIN_ROOT:-${CURSOR_PLUGIN_ROOT:-}}}/scripts"
   python3 "$SCRIPT_DIR/session_stats.py" peek

2. Parse the recent_ids array from the JSON output. Each entry has id, category, ts. 3. Show the last N entries (default 1) and ask for confirmation. 4. Delete confirmed entries via delete_memory.

If recent_ids is empty, tell the user: "No recent memory IDs tracked this session. Try /mem0:tour to browse recent memories, or /mem0:forget <search query> to find specific ones."
