SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Removing outdated, incorrect, or sensitive memories from a mem0 store is risky without safeguards. This Skill locates the right memories and enforces confirmation before any destructive deletion. ## Core Features & Use Cases - Search-Based Deletion: Find memories by natural language query scoped to the active user and project, then select which ones to remove. - Direct ID Deletion: Verify a memory by its ID, preview its content, and delete it after confirmation. - Session Undo: Roll back memories added in the current session using the MEM0_SESSION_ID environment variable. - Use Case: After an experiment stores incorrect architecture decisions, run a search for the topic, review the numbered matches, and delete only the confirmed entries. ## Quick Start Ask the assistant to forget memories about a topic, for example: delete the memories about the old authentication module decisions.

Frequently Asked Questions about mem0-forget

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I delete memories from mem0 by search query?▼

Provide a search query and the skill calls search_memories filtered by your user ID and project ID, returning up to 10 matches. You then confirm which numbered results to delete, and each confirmed entry is removed via delete_memory.

How do I undo recently added memories in mem0?▼

Say 'undo last N memories' and the skill reads the MEM0_SESSION_ID environment variable to find memories tagged with the current session. It sorts them by creation time, shows the most recent entries, and deletes them after your confirmation.

Can I delete a mem0 memory by its ID?▼

Yes, pass the memory ID directly and the skill calls get_memory to verify it exists and shows a content preview with its creation date. Deletion only proceeds after you confirm the prompt.

Does mem0 deletion happen without confirmation?▼

No, the skill never deletes without explicit confirmation because deletion is destructive. You must enter item numbers, 'all', or answer yes to the confirmation prompt before any delete_memory call runs.

What happens if no recent memories are found to undo?▼

If MEM0_SESSION_ID is unset or the session-filtered search returns nothing, the skill reports that no recent memory IDs were tracked. It suggests browsing recent memories or searching by query instead.
