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 Use when removing outdated decisions, incorrect memories, sensitive data, or cleaning up after experiments.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.
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.
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 Use when removing outdated information, incorrect memories, sensitive data, or cleaning up after experiments.
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 auth module decisions/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):
get_memory with the ID to verify it exists.Found: "<memory content first 120 chars>" (created <date>)If search query provided:
search_memories with:
query=<user's query>filters={"AND": [{"user_id": "<active_user_id>"}, {"app_id": "<project_id>"}]}top_k=10Found <N> memories matching "<query>":
1. <content, 120 chars> (type: <type>, created: <date>) [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, call delete_memory with the memory ID.
Deleted <N> memories.
If any deletions failed, report which ones and why.
If the user says "undo last N memories" or "undo last write":
MEM0_SESSION_ID environment variable (set by the plugin's shell.env hook).MEM0_SESSION_ID is set, call search_memories with:
query="recently added"filters={"AND": [{"user_id": "<active_user_id>"}, {"app_id": "<project_id>"}, {"metadata": {"session_id": "<MEM0_SESSION_ID>"}}]}top_k=20delete_memory.If MEM0_SESSION_ID is not set or the search returns no results, 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."
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.
