What this skill does
Mem0 Forget Delete specific memories from mem0. Execution Step 1: Parse input The user provides either: A search query: /mem0-forget auth module decisions A memory ID: /mem0-forget <memoryid> If no argument, ask: "What should I forget? Provide a search query or memory ID." Step 2: Find memories If memory ID provided (looks like a UUID or hex string): Call getmemory with the ID to verify it exists. Show: Found: "<memory content first 120 chars>" (created <date>) If search query provided: Call searchmemories with: query=<user's query> filters={"AND": [{"userid": "<activeuserid>"}, {"appid": "<projectid>"}]} topk=10 Show numbered list: Step 3: Confirm 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. Step 4: Delete For each confirmed memory, call deletememory with the memory ID. Step 5: Report If any deletions failed, report which ones and why. Undo recent writes If the user says "undo last N memories" or "undo last write": 1. Check the MEM0SESSIONID environment variable (set by the plugin's shell.env hook). 2. If MEM0SESSIONID is set, call searchmemories with: query="recently added" filters={"AND": [{"userid": "<activeuserid>"}, {"appid": "<projectid>"}, {"metadata": {"sessionid": "<MEM0SESSIONID>"}}]} topk=20 3. Sort results by creation time descending and show the last N entries (default 1). Ask for confirmation. 4. Delete confirmed entries via deletememory. If MEM0SESSIONID 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." 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. …
