Mem0 Pin

Pin a memory to mark it as high-priority and protect from pruning.

Execution

Step 1: Find the memory

The user provides either a search query or memory ID.

If memory ID:

• Call get_memory with the ID.

If search query:

• Call search_memories with the query, filters={"AND": [{"user_id": "<id>"}, {"app_id": "<pid>"}]}, top_k=5.
• Show numbered list with content previews.
• Ask: "Which memory to pin? Enter a number."

Step 2: Read current content

Call get_memory with the selected memory ID. Store:

• original_text — the memory's text content
• original_metadata — the existing metadata dict

Step 3: Pin it

The update_memory tool updates a memory by id. To pin durably, append a pin marker to the text so it travels with the memory:

pinned_text = "[PINNED] " + original_text if not original_text.startswith("[PINNED]") else original_text
update_memory(id=<selected_id>, text=pinned_text)

For new memories (user wants to pin text that isn't stored yet):

1. Call add_memory with:

• text="[PINNED] <the user's text>"
• user_id=<active_user_id>
• app_id=<active_project_id>
• metadata={"pinned": true, "type": "decision", "confidence": 1.0}
• infer=False

1. The response contains event_id. Call get_event_status(event_id=<event_id>) once to retrieve the memory ID, then confirm.

Step 4: Confirm

Pinned: "<memory content, first 80 chars>"
Memory ID: <id>

Append ... only if content exceeds 80 characters.

Unpin

If the user says "unpin":

1. Call get_memory to read current content.
2. Remove the pin marker from the text:

``python unpinned_text = original_text.removeprefix("[PINNED] ") update_memory(memory_id=<id>, text=unpinned_text) ``

1. Print: Unpinned: "<content>..."

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.
