description: Delete specific observations from agentmemory after showing them and getting explicit confirmation. Use when the user says "forget this", "delete memory", "remove that note", or wants to scrub specific data for privacy.

The user wants to remove data from agentmemory: $ARGUMENTS

## Quick start

```json
memory_smart_search { "query": "old api key in config", "limit": 20 }
```

Show the matches, get a yes, then:

```json
memory_governance_delete { "memoryIds": ["abc12345", "def67890"], "reason": "user privacy request" }
```

Expected output:

```text
Found 2 matching memories. Confirmed. Deleted 2 memories.
```

## Why

This is destructive and irreversible. Show exactly what will be deleted and get
an explicit yes before calling delete. Delete by memory ID, never a bare session.

## Workflow

1. Search with `memory_smart_search`, the user's text as `query`, `limit: 20`.
2. Show what matched: session ids, memory ids, titles. Ask for explicit
   confirmation. Do not proceed on silence or a vague "sure, whatever".
3. On confirmation, call `memory_governance_delete` with `memoryIds` (array or
   comma-separated string) and optional `reason` (default `plugin skill request`).
4. To drop a whole session, collect every memory id in that session from the
   search results and pass them all. The MCP does not accept a bare `sessionId`.
5. Lessons are separate: delete one with `memory_lesson_delete` and its
   `lessonId`; `memory_governance_delete` does not touch lessons.
6. Report the deletion count back. A count of 0 means the ids did not exist;
   say so instead of claiming a delete.

## Anti-patterns

WRONG: search returns matches, you immediately call `memory_governance_delete`
without showing them or waiting for a yes.

RIGHT: list the matches, ask "Delete these 2? (yes/no)", and only delete after
an explicit yes.

## Checklist

- Matches were shown to the user before any delete.
- An explicit yes was received, not assumed.
- `memoryIds` holds real ids from the search, never a bare `sessionId`.
- Final message states the actual count deleted.

- `recall`: find the exact memory id before deleting.

## Troubleshooting

See ../_shared/TROUBLESHOOTING.md if `memory_smart_search` or `memory_governance_delete` is not available.
