forget	Deletes memories by search query or memory ID with confirmation before removal. Use when removing outdated decisions, incorrect memories, sensitive data, or cleaning up after experiments. Also handles undo of recent additions.

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."
