Deletes memories by search query or memory ID with confirmation before removal. Use when removing outdated information, incorrect memories, sensitive data, or cleaning up after experiments.
Plan and then execute a migration of a project from the mem0 open-source / self-hosted SDK (the local `Memory` class) to the mem0 Platform / hosted / managed SDK (the `MemoryClient` class). Use this whenever a developer wants to move, switch, or migrate their mem0 usage off OSS/self-hosted to the hosted API — e.g. "migrate my mem0 setup to the platform", "switch from self-hosted mem0 to MemoryClient", "use my mem0 API key instead of a local Qdrant", "move mem0 to the cloud/hosted/managed service", or "replace my local mem0 vector store + embedder config with the platform". Applies to Python (`from mem0 import Memory` → `from mem0 import MemoryClient`) and TypeScript/JavaScript (`import { Memory } from "mem0ai/oss"` → `import MemoryClient from "mem0ai"`). Trigger even when the user doesn't say the word "migrate" but clearly wants their existing mem0 integration to run against the hosted platform. It first produces a reviewable migration plan, then executes it after the developer approves. Strictly scoped to th
Searches and injects relevant memories into context before starting work on a task or topic. Use when beginning a new task, switching context, or when past decisions, preferences, or knowledge need to be loaded.
Consolidates stored memories by merging duplicates, resolving contradictions, and pruning stale entries. Use when memory count is high, search results feel noisy or repetitive, or periodic cleanup is needed to maintain memory quality.
Pins or unpins a memory to protect it from pruning during dream consolidation. Use when a memory is critical and must never be removed, such as core preferences, important decisions, or immutable personal facts.
Stores a memory verbatim from user input with appropriate category classification. Use when the user says remember this, save this, store this, note that, or explicitly asks to record a preference, decision, goal, or lesson.
Searches memories and displays compact one-liner results, or looks up a specific memory by ID. Use for quick memory lookups, checking if something was recorded, resolving [mem0:id] citations, or browsing memories without full category detail.

Delete specific memories from Mem0.
The user provides either:
/mem0-forget travel plans/mem0-forget <memory_id>If no argument, ask: "What should I forget? Provide a search query or memory ID."
If memory ID provided (looks like a UUID or hex string):
mem0_memory tool with action="search" and the ID as query, or look it up directly.Found: "<memory content first 120 chars>" (created <date>)If search query provided:
mem0_memory tool with action="search", query=<user's query>.Found <N> memories matching "<query>":
1. <content, 120 chars> [<category>] [ID: <short_id>]
2. ...
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.
For each confirmed memory, use mem0_memory tool with action="delete" and the memory ID.
Deleted <N> memories.
If any deletions failed, report which ones and why.
